Introduction
The sustainable use of rapidly diminishing marine resources by consumers is a priority for species conservation. Marine resources have long been used for medicinal, experiential and sensory purposes by communities globally, and there is increasing concern about overexploitation of these resources (Thomas-Walters et al., Reference Thomas-Walters, Hinsley, Bergin, Burgess, Doughty and Eppel2021). In Southeast Asia, most consumption of wildlife including marine resources is deeply rooted in the traditional beliefs and practices of local communities and is an integral part of their lives and livelihoods (Cheung et al., Reference Cheung, Doughty, Hinsley, Hsu, Lee and Milner-Gulland2021; Thomas-Walters et al., Reference Thomas-Walters, Hinsley, Bergin, Burgess, Doughty and Eppel2021). However, these culturally driven practices are rarely integrated into species conservation measures and sustainable resource management (Cheung et al., Reference Cheung, Doughty, Hinsley, Hsu, Lee and Milner-Gulland2021).
Seahorses Hippocampus spp. are a marine resource of commercial and cultural importance. They are used in multiple ways, which could make them more sought-after than other marine species. These bony fishes belong to the family Syngnathidae (Froese & Pauly, Reference Froese and Pauly2011) and live in tropical and temperate shallow waters in habitats such as seagrass meadows and coral reefs (Choo & Liew, Reference Choo and Liew2003; Salin et al., Reference Salin, Yohannan and Mohanakumaran Nair2005). Seahorses are closely associated with bottom habitats and considered key predators of bottom-dwelling organisms (Tipton & Bell, Reference Tipton and Bell1988; Foster & Vincent, Reference Foster and Vincent2004). They are slow swimmers and display traits of low fecundity, mate and site fidelity and obligate parental care (Vincent & Sadler, Reference Vincent and Sadler1995; Foster & Vincent, Reference Foster and Vincent2004). These biological characteristics render them highly vulnerable to localized overexploitation and depletion (Vincent, Reference Vincent1996; Otero-Ferrer et al., Reference Otero-Ferrer, González, Freitas, Araújo, Azevedo and Holt2017).
All known seahorse species are listed on Appendix II of CITES, which regulates international trade (McPherson & Vincent, Reference McPherson and Vincent2004). The global seahorse trade is driven by their perceived medicinal and cultural importance. For example, seahorses are valued as key ingredients in traditional medicine used to support the well-being of millions of people (WHO, 2002). Dried forms of seahorses are consumed in traditional Chinese medicine and other traditional and complementary medicinal practices, with an estimated over 20 million dried seahorses traded globally annually since the 1980s (Vincent, Reference Vincent1996; Foster & Vincent, Reference Foster and Vincent2005). Seahorses reportedly increase and balance energy flow and cure conditions such as impotence and infertility, high cholesterol, kidney disorders, goitres, asthma and skin conditions such as acne and allergies (Rosa et al., Reference Rosa, Defavari, Alves, Oliveira, Alves and Rosa2013). Consumers also believe that medicines derived from seahorses act as a genital tonic and an aphrodisiac and that they facilitate parturition (Vincent, Reference Vincent1995, Reference Vincent1996). Besides consuming dried seahorses for their medicinal value, coastal Malay communities also use seahorse extracts in ointments for external medicinal application, and they believe in keeping dried seahorses to repel evil spirits (Choo & Liew, Reference Choo and Liew2005). In addition, dried seahorses are used as curios, souvenirs and jewellery, and live seahorses are also kept as aquarium fishes (Choo & Liew, Reference Choo and Liew2005; Perry et al., Reference Perry, Lunn and Vincent2010).
The seahorse trade involves various actors including fishers, buyers, exporters, wholesalers and retailers before reaching end consumers (Vincent, Reference Vincent1996). In recent years, conservationists have recognized that interventions aimed at end consumers are an important approach to help curb unsustainable wildlife consumption and shift to more sustainable alternatives (Veríssimo & Wan, Reference Veríssimo and Wan2018; Veríssimo et al., Reference Veríssimo, Schmid, Kimario and Eves2018). To implement such interventions, it is vital to understand consumer behaviours and use patterns (Vincent, Reference Vincent1996). In the absence of formal records of seahorse uses, surveying resource users such as members of the public may be the best available method of gathering information across large geographical areas within practicable timeframes (Perry et al., Reference Perry, Lunn and Vincent2010). Clarification of the role of consumers in driving unsustainable wildlife trade could also create opportunities for communities to support marine management (McKinley & Fletcher, Reference McKinley and Fletcher2012).
Malaysia, a multicultural country with over 65 ethnic groups, is home to vital seahorse habitats and is located at the centre of the Indo-Pacific seahorse trade (Vincent, Reference Vincent1996; Choo & Liew, Reference Choo and Liew2005). Eight of the 12 seahorse species found in Malaysian waters are commonly traded (Lim et al., Reference Lim, Chong, Wong and Choo2011; Aylesworth et al., Reference Aylesworth, Lawson, Laksanawimol, Ferber and Loh2016), reportedly for use in traditional Chinese medicine (Perry et al., Reference Perry, Lunn and Vincent2010). Seahorse exportation is not banned in Malaysia, but claims of there being no such exportation have been made since 2014 (Foster, Reference Foster2023). Seahorses are not protected locally, and there are no local regulations of seahorse trade or catch despite the fact that eight out of the 12 local species are categorized as Vulnerable on the IUCN Red List (IUCN, 2021). Local traditional medicinal use of seahorses has been and purportedly still is widespread for the treatment of diseases amongst Malaysian communities (Halim et al., Reference Halim, Salleh, Mohamed, Mat and Yusof2017). The use of seahorses and their associated cultural value in Malaysia varies between regions (Choo & Liew, Reference Choo and Liew2005), and documentation on the culturally specific uses of seahorses and the purported benefits remains sparse.
Overlooking socio-cultural complexities can undermine conservation effectiveness (Bennett et al., Reference Bennett, Roth, Klain, Chan, Christie and Clark2017; Margulies et al., Reference Margulies, Wong and Duffy2019). Therefore, our study aimed to address knowledge gaps by examining how ethnicity and other socio-demographic drivers shape seahorse use amongst Malaysians, using a questionnaire-based survey. Additionally, we aimed to determine the perceptions of survey respondents regarding the level of threats to seahorses. We hypothesized that seahorse uses would be closely associated with ethnic group, gender, education level, locality, location setting and occupational background (Kellert & Berry, Reference Kellert and Berry1980; Thompson & Mintzes, Reference Thompson and Mintzes2002; Choo & Liew, Reference Choo and Liew2005; Suleiman, Reference Suleiman2014; Boakye, Reference Boakye2018; Naylor & Parsons, Reference Naylor and Parsons2018).
Study area
Malaysia is a Southeast Asian country that is home to three major ethnic groups: Malays (70% of the population), Chinese (23%) and Indians (6%), as well as many other, smaller groups (1%; Department of Statistics Malaysia, 2022). Ethnic composition of the population varies by region, and we considered four major regions for the purposes of this study: the west, east and south coasts of Peninsular Malaysia, and Borneo. In Peninsular Malaysia, the Indigenous communities, collectively known as Orang Asli, comprise three major groups: Negrito, Senoi and Proto-Malay. Within Borneo, of the c. 60 ethnic groups, the Kadazandusun and Iban are the major ethnic groups in the states of Sabah and Sarawak, respectively (Department of Information, 2016). In Peninsular Malaysia, fishers are predominantly Malays (65.3%), followed by Chinese (31.1%), other ethnicities (2.5%) and Indians (1.1%; Department of Fisheries Malaysia, 2021).
Methods
Survey design
To gain insights into seahorse use by the general public, we hosted a questionnaire-based survey on Google Forms (Google, 2022) for 14 months during March 2021–April 2022. Google Forms is an appropriate survey tool for gathering information over large geographical areas within practicable timeframes (Nurmahmudah & Nuryuniarti, Reference Nurmahmudah and Nuryuniarti2020). This online approach was necessary because of the travel restrictions related to the Covid-19 pandemic that were in effect during the survey period. We distributed the form through various online and social media platforms to ensure we reached a wide range of respondents from various backgrounds. Specifically, we posted the questionnaire link on the Facebook (Meta Platforms, 2022a) and Instagram (Meta Platforms, 2022b) pages of Save Our Seahorses (SOS) Malaysia, a local NGO, and on the personal profiles of team members. In addition, we also circulated the form randomly to contacts of the authors via the messaging apps Telegram (Telegram, 2022) and WhatsApp (Meta Platforms, 2022c).
The online approach alone would probably fail to reach the fisher groups that are of interest for this study. Therefore, we concurrently conducted a survey targeted specifically at fishers, which had overlapping questionnaire components with the online public survey. We administered the fisher survey either face to face or through phone calls with fishers from Peninsular Malaysia. We located the fisher respondents using snowball and haphazard sampling (Gubrium & Holstein, Reference Gubrium and Holstein2001), whereby we obtained fisher contacts from initial respondents, local fisher associations and fishmongers.
The questionnaire-based survey (henceforth referred to as the public survey) and the overlapping subset of the fisher survey consisted of three main sections with 26 questions (Supplementary Material 1). We determined respondent knowledge and perceptions of seahorse uses including underlying motivations to consume seahorses (medicinal and non-medicinal uses) across ethnic cultures. We also recorded the respondents’ perceptions of the level of threats to seahorses. We identified the socio-demographic characteristics such as gender, age, ethnicity, location of residence (state), location setting (urban vs rural/semi-rural) and education level of the respondents. We adapted the questionnaire from other studies related to the use of seahorses (Salleh et al., Reference Salleh, Mohamed, Mat, Yusof, Samsuddin, Razali and Wan Talaat2020) and with the guidance of field experts (authors AY-HT and ACOL). We derived the options for the questionnaire sections exploring underlying motivations and aspects relating to health conditions from Salleh et al. (Reference Salleh, Mohamed, Mat, Yusof, Samsuddin, Razali and Wan Talaat2020). Each questionnaire took c. 10–15 min to complete.
Before conducting the surveys, we tested and refined the questionnaire using test groups. The University of Malaya Research Ethics Committee (UMREC) approved the questionnaire and issued an ethical permit (UM.TNC2/UMREC – 1225). In accordance with the approved ethics protocol, the interviewer disclosed the project objectives to each respondent, requested their informed consent, informed them that participation was voluntary and anonymous and gave assurances that the interviewee could terminate the survey at any time.
We restricted the survey to members of the public and fishers of Malaysian nationality who were at least 18 years old and residing in Malaysia. Estimation of the sample size of respondents would ideally be based on data regarding the proportions of the various ethnic groups consuming seahorses, but these were not available. Using the Australian Bureau of Statistics sample size calculator and relevant adult population statistics (see Supplementary Table 1 for details), we obtained expected minimum sample sizes of 269 Malays, 86 Chinese, 26 Indians and four individuals from other ethnic groups.
Data analysis
We summarized the diversity and type of seahorse use (medicinal uses; other uses; both) and underlying motivations by ethnic group (Malay; Chinese; Indian; Indigenous; others) and background (general public; fishers). Ethnicity and culture are used synonymously in this article as ethnic identity is an important determinant of cultural values (Loue, Reference Loue, Gellman and Turner2013; Mohd Yusuf et al., Reference Mohd Yusuf, Azzah and Kamil2016). We categorized medicinal uses into five types: external treatments (of symptoms or diseases), internal treatments (of symptoms or diseases), support of general well-being, uses based on aphrodisiac properties, and uncertain health benefits. We categorized other (non-medicinal) uses into five types: curios/souvenirs, pets in aquariums, protection against evil spirits, to put a spell on someone, and for research and educational purposes (display material).
Given the potential bias in using online surveys for data collection (under-representation of certain groups, such as older age groups or those from rural areas), we weighted the samples to reduce such bias. We applied the raking method for weighting (Pew Research Center, 2018), and conducted univariate statistical analyses (see below) on both weighted and unweighted samples. As the conclusions drawn were similar for both weighted and unweighted samples (Supplementary Table 1), we present the results of the analyses based on the unweighted samples.
We analysed the patterns of seahorse uses using χ 2 tests and Fisher's exact tests. For ethnic-based analyses of medicinal and other uses, we pooled respondents from three groups (Indian, Indigenous, others) because of their small sample sizes. We excluded the 10 respondents who had consumed seahorses but were unsure of the health benefits from the analysis. We compared perceptions of the valuableness of seahorses and of the level of threats facing them between the general public and fisher respondents. We conducted all statistical analyses using R 4.3.0 (R Core Team, 2023). For all comparisons, we considered P < 0.05 to be significant.
We used the classification tree method (a machine learning approach) to explore the key explanatory variables underlying the pattern of seahorse use. We included six socio-demographic (categorical) variables in the model-building process: gender (male; female; both/prefer not to say), age (18–30; 31–40; 41–50; 51–60; > 60 years old), ethnicity (Malay; Chinese; Indian; Indigenous; others), education (none; primary; secondary; tertiary; postgraduate), region of residence (west, east or south coasts of Peninsular Malaysia; Borneo) and occupational background (fisher; general public). We constructed the classification tree using the party package in R (Hothorn et al., Reference Hothorn, Hornik and Zeileis2006).
Results
We obtained 1,189 responses from 637 members of the public and 552 fishers from across all four regions in Malaysia (Figs 1 & 2). The ethnic groups represented were Malays, Chinese, Indians and Indigenous, and other minority ethnic groups collectively categorized as ‘others’. The majority of public respondents were women (64.8%), whereas almost all fisher respondents were men (99.8%). Most of the public respondents were 18–30 years old (54.3%) and more than one-third were of Chinese ethnicity (38.5%). For the fisher respondents, one-third were 41–50 years old and most (88.0%) were from the Malay ethnic group (Table 1).

1 We did not collect information regarding the occupational background of the public respondents, and they were assumed to be primarily non-fishers (Lennox et al., Reference Lennox, Sbragaglia, Wiik Vollset, Sortland, McClenachan and Jaric2022).
A total of 21.0% (n = 250) of respondents reported using seahorses, the majority being men (90%, 225). Amongst the seahorse users, 20.8% (52) were public respondents and 79.2% (198) were fishers. Amongst the public respondents, 5.9% of Malays (12), 15.1% of Chinese (37) and 2.7% of Indians (3) reported using seahorses. Amongst the fisher respondents, 39.1% of Malays (190), 10.9% of Chinese (6) and 11.1% of Indians (1) reported using seahorses. Amongst the Malay seahorse users, most were fishers (94.1%, 190); whereas amongst the Chinese and Indian users, the majority were members of the general public (86.0%, 37 and 75.0%, 3, respectively; Fig. 3). The only reported seahorse use by respondents from the Indigenous (n = 60) and other (n = 16) groups was a single Malaysian Siamese fisher (Fig. 3). A small fraction of the fishers interviewed (2.4%) had used seahorses in the past but no longer did so. Reasons for this cessation of seahorse use included changes in the tradition of using seahorses for spiritual purposes, shifts in opinion regarding the tradition, shifts in perceptions through increased awareness of conservation aspects, lack of seahorse catches and the complexities of keeping live seahorses as aquarium fishes. Consumption status (yes or no) of seahorses was related to the ethnicity (χ 2 = 77.56, df = 3, P < 0.05) and gender (two-tailed P < 0.05) of respondents in both the general public and fisher groups.
Types of seahorse use amongst the 637 general public respondents and 552 fisher respondents of various ethnic groups surveyed from Peninsular Malaysia and Borneo. Percentages of prior use (medicinal use; other uses; both) and respondent group (general public; fisher) are expressed as per ethnic group; sample sizes per group are indicated to the right of each bar.
Amongst seahorse users, 34.4% (86) reported consuming seahorses for medicinal purposes, 55.2% (138) for other purposes and 10.4% (26) for both medicinal and other purposes. The two most common motivations for consuming seahorses for medicinal purposes were to treat diseases (73.2%) and to maintain health and prevent diseases (68.8%). Other reported motivations were cultural beliefs, the pleasant taste of seahorses and views on seahorse-based traditional medicine (e.g. compared to using modern medicine, using seahorses in traditional medicine was perceived as being more effective and having fewer side effects, or the current health condition of the respondent was perceived as not sufficiently severe to necessitate modern medication).
Proportionally, more Malay respondents reported medicinal use of seahorses than other ethnic groups. The primary traditional medicine uses of seahorses were to treat asthma (n = 45 respondents) and skin conditions (41) and to strengthen the body (22). A comprehensive list of reported medicinal uses of seahorses is available in Supplementary Table 2, and direct quotes relating to seahorse use by members of the various ethnic groups in Supplementary Table 3. A small fraction of respondents who consumed seahorses (3.6% of Malay and 4.5% of Chinese respondents) were unsure regarding the health benefits. However, medicinal use types were not associated with the ethnicity of respondents (two-tailed P > 0.05). More Malay respondents (92.7%) reported other use types of seahorses than the other ethnic groups collectively. The most common non-medicinal use was as curios/souvenirs (n = 140; see Supplementary Table 4 for an exhaustive list of other seahorse uses). Types of other uses of seahorses were closely associated with the ethnicity of respondents (two-tailed P < 0.05). In terms of location settings, only the Malay respondents were relatively well represented in both categories of uses. The Malay public respondents who lived in urban settings reported a greater diversity of medicinal uses (four types) compared to those in rural/semi-rural settings (two types).
Regarding the perceived valuableness of seahorses, a relatively large proportion of the public respondents were unsure of this with respect to health benefits (50.5%) and cultural values (41.7%). However, over one-third of the public respondents (35.8%) stated that seahorses are economically valuable, and most agreed that seahorses are valuable to the ecosystem (86.7%) and for recreational purposes (e.g. scuba diving, aquarium visit or as a pet; 76.9%). Many of the fisher respondents were unsure of the valuableness of seahorses (health: 59.4%; economical: 47.1%; cultural: 66.3%; recreational: 45.1%; ecosystem value: 42.8%; Table 2). Perceptions of valuableness were significantly associated with whether respondents used seahorses for the categories of health (χ 2 = 151.31, df = 2, P < 0.05), ecosystem (χ 2 = 38.29, df = 2, P < 0.05) and recreational values (χ 2 = 8.40, df = 2, P < 0.05), but there was no such association for economical (χ 2 = 3.72, df = 2, P > 0.05) and cultural values (χ 2 = 0.80, df = 2, P > 0.05).
Perceptions of the 637 general public respondents and 552 fisher respondents surveyed from Peninsular Malaysia and Borneo on the valuableness of seahorses.
Many of the public respondents were aware of threats to seahorses, particularly habitat destruction (72.1% of respondents) and ocean plastic pollution (65.9%); fewer considered overfishing (42.5%) and bycatch (37.0%) as major threats (Fig. 4a). In contrast, most of the 552 fisher respondents were unsure of the existence and/or severity of the threats to seahorses. Relatively more fisher respondents (38.9%) ranked bycatch as a major threat compared to the other threats (Fig. 4b).

The classification tree identified four variables that were important in explaining the patterns of seahorse use: education level, region of residence, ethnicity and gender. Respondents with tertiary or postgraduate education were less likely to use seahorses in any manner, with the exception of men of Chinese ethnicity (Fig. 5). For individuals with lower education levels (no formal education, or with primary- or secondary-level education), seahorse use was associated with region of residence and ethnicity: those of Malay or Indian ethnicities, and those belonging to various non-Indigenous minority groups, who lived in the east and south coast areas of Peninsular Malaysia had a greater likelihood of seahorse use (Fig. 5).
Classification tree model exploring patterns of seahorse use amongst the 637 general public respondents and 552 fisher respondents from Peninsular Malaysia and Borneo based on socio-demographic variables: education, region (WC = west coast, EC = east coast and SC = south coast of Peninsular Malaysia; Borneo), ethnicity (MAL = Malay; CHI = Chinese; IND = Indian; IGE = Indigenous; OTH = others) and gender. The tree model begins with the entire dataset, forming a root node (variable) at the top of the tree, and uses recursive binary splits by evaluating every predictor to form partitions of the sample into more homogeneous subsets (or nodes) that represent intermediate decisions. Six final nodes at the bottom of the tree represent the final outcomes. The dark and light grey portions of the bars represent the proportion of respondents who do and do not use seahorses, respectively. Probabilities of seahorse use (on a scale from 0 to 1) are indicated within each node, including the final nodes.
Discussion
Our study shows that seahorse uses amongst Malaysians are closely associated with ethnic groups, which can be attributed to culturally specific (ethnomedicinal) practices (Choo & Liew, Reference Choo and Liew2005; Boakye, Reference Boakye2018). To our knowledge, this study provides the first documentation of seahorse use by Indian and Malaysian Siamese respondents in Malaysia. Such sociocultural insights could enable conservationists to develop effective interventions that are strategically targeted at particular demographic groups (Cheung et al., Reference Cheung, Doughty, Hinsley, Hsu, Lee and Milner-Gulland2021). That traditional medicine use of seahorses has not previously been reported within the Indian community could be attributed to the primary use of plant-based ingredients in Indian medicinal practice (Adhikari & Paul, Reference Adhikari and Paul2018).
The practice of traditional and complementary medicine is relatively widespread; a previous study found that 69.4% of Malaysians (n = 6,947) had used traditional and complementary medicine (Siti et al., Reference Siti, Tahir, Ida Farah, Ami Fazlin, Sondi and Azman2009). However, we found a low prevalence of the medicinal use of seahorses, which is consistent with results from a week-long online poll administered via the Facebook page of SOS Malaysia, in which 87.0% of Malaysian respondents (54) indicated they had not used seahorses in any way (Lim, Reference Lim2021). Nevertheless, the reported medicinal uses and benefits in our study are consistent with previous studies that noted seahorses as the most frequently mentioned marine resource in traditional medicine because of their perceived efficacy for treating a variety of ailments and for promoting well-being (Vincent, Reference Vincent1996; Sari et al., Reference Sari, Nurilmala and Abdullah2018; Salleh et al., Reference Salleh, Mohamed, Mat, Yusof, Samsuddin, Razali and Wan Talaat2020). Medicinal use by the Chinese ethnic group, especially amongst the respondents from the general public, could be attributed to the centuries-long strong establishment of seahorses in Chinese pharmacopoeia (Vincent, Reference Vincent1996).
Ethnicity influences non-medicinal uses of seahorses, which, along with medicinal uses, are classified as consumption uses of natural resources (Gomez et al., Reference Gomez, Vliet and Canales2022). Amongst the fisher respondents, the Malay ethnic group commonly reported consuming seahorses for non-medicinal uses. The influence of psychosocial factors such as perceptions, beliefs, attitudes and cultural values in shaping food choices and behaviours (Nestle et al., Reference Nestle, Wing, Birch, DiSogra, Drewnowski and Middleton1998) could have driven their choice to consume seahorses, especially via word of mouth or hearsay amongst family members and friends. A preliminary study showed that seahorse curios represented the second most common type of seahorse trade after traditional medicine on online market platforms in Malaysia (Aminuddin et al., Reference Aminuddin, Then and Lim2021). Thus, conservation strategies should focus on managing these types of seahorse use in both physical and online marketplaces (Challender et al., Reference Challender, Harrop and MacMillan2015; Di Minin et al., Reference Di Minin, Fink, Hiippala and Tenkanen2019).
Our findings indicate that culturally sensitive outreach strategies for conserving seahorses need to target the medicinal uses amongst Malay and Chinese communities, but that this is less relevant for other ethnic groups. A previous study concluded that conservation management awareness campaigns should be targeted at communities of specific ethnic backgrounds in the context of users of pangolin body parts for traditional medicine in Ghana (Boakye, Reference Boakye2018). This indicates the need to design conservation efforts to be appropriate to the nature and circumstances of the communities they target. Enforcement-led approaches to marine resource management are most effective when they are built upon values that are compatible with those held by the most affected communities (Challender et al., Reference Challender, Harrop and MacMillan2015; Cooney et al., Reference Cooney, Roe, Dublin, Phelps, Wilkie and Keane2017).
Locality is a socio-demographic variable that affects the attitudes of people towards the natural environment (Naylor & Parsons, Reference Naylor and Parsons2018). We found greater diversity in medicinal uses of seahorses amongst the Malay public members residing in urban compared to rural/semi-rural settings. Knowledge transfer regarding traditional medicine uses may be more widespread amongst individuals from urban areas because of their greater use of the internet and social media, thereby influencing their positive perceptions of the health benefits of seahorses. Others have noted that the transfer of knowledge is vital for preserving medical practices in the community (Suleiman, Reference Suleiman2014; Jamshed et al., Reference Jamshed, Khan, Ahmad and Elkalmi2016). Stronger seahorse consumer markets and a greater influence of traditional Chinese medicine, especially because there are more traditional Chinese medicine shops in urban areas, may facilitate access to seahorses in cities compared to rural/semi-rural areas (Zhao et al., Reference Zhao, Tang, Mao and Akinyemiju2022). The greater seahorse use amongst respondents on the east coast of Peninsular Malaysia is probably linked to the greater quantities of seahorses caught there compared to other regions (Perry et al., Reference Perry, Lunn and Vincent2010). It is also a common practice amongst Malay east coast fishers to eat deep-fried seahorses as crackers (Choo & Liew, Reference Choo and Liew2005).
Education is another factor that affects attitudes towards conservation issues (Kellert & Berry, Reference Kellert and Berry1980). Our study indicated that individuals with a lower educational level generally showed a higher likelihood of seahorse use. Education is also likely to change individual perceptions of biodiversity conservation (Kellert, Reference Kellert1996), as seen in various studies linking higher educational levels to improved public knowledge of various marine species and a more conservation-positive attitude towards them (Thompson & Mintzes, Reference Thompson and Mintzes2002; Barney et al., Reference Barney, Mintzes and Yen2005; O'Bryhim & Parsons, Reference O'Bryhim and Parsons2015). With most fishers having lower educational levels, general awareness of marine life, including seahorses, amongst coastal people in Malaysia remains an educational priority (O'Bryhim & Parsons, Reference O'Bryhim and Parsons2015; Naylor & Parsons, Reference Naylor and Parsons2018).
Amongst those with a higher education level, men of Chinese ethnicity are more likely to consume seahorses than women or those from other ethnicities. The attitudes of men and women regarding marine conservation issues were previously found to be significantly different (Naylor & Parsons, Reference Naylor and Parsons2018). Women tend to value animals more highly and are more concerned about their exploitation, leading to stronger conservation attitudes; in contrast, men are more inclined to value animals in terms of recreational and practical purposes (Kellert & Berry, Reference Kellert and Berry1980). This suggests that gender is another demographic factor that should be considered when shaping conservation messages.
From a conservation standpoint, it is positive that most respondents, including fishers, regarded seahorses as more valuable alive (i.e. in the ecosystem) than when harvested for medicinal or culturally motivated uses. Attitudes towards marine conservation can vary considerably depending on the issue in question (Naylor & Parsons, Reference Naylor and Parsons2018). The greater awareness of the severity of habitat destruction and ocean plastic pollution amongst the wider public could be because of the increased global media attention given to these issues in recent years (Barney et al., Reference Barney, Mintzes and Yen2005). However, the lack of awareness of the severity of overfishing and bycatch, including of seahorses, suggests that more efforts are required to promote public discourse on these issues, including amongst fishers.
In an earlier study, traders reported a decrease in seahorse sales and demand because of diminishing interest in consuming seahorses as traditional medicine, especially amongst the younger generations (Perry et al., Reference Perry, Lunn and Vincent2010). We corroborated this in another aspect of our study via informal interviews with traditional medicine practitioners and seahorse traders (R.M.Y. Ng, A.C.O. Lim, C.N.B. Henry Chin Siew Lee, N.B. Abdul Majib, M.A. Syed Hussein & A.Y.H. Then, unpubl. data, 2024). These declines could be attributed to reported declines in bycatch volumes by fishers (Choo & Liew, Reference Choo and Liew2005; Perry et al., Reference Perry, Lunn and Vincent2010), driven by overfishing and/or habitat degradation (Perry et al., Reference Perry, Lunn and Vincent2010). Collectively, this evidence suggests that seahorse use amongst Malaysians has decreased and is now generally low.
Seahorse uses amongst minority ethnic groups and elderly people in Malaysia were less well documented in the public survey because of the limited ability to reach these groups online. Future survey-based studies should focus on reaching these groups and on including occupational information (Perry et al., Reference Perry, Lunn and Vincent2010; Naylor & Parsons, Reference Naylor and Parsons2018) to gain insights into these aspects. Regarding the effects of location setting on seahorse use amongst members of the public, there is an under-representation of perceptions from the rural/semi-rural settings. Given the relatively large scale of seahorse harvesting amongst the rural communities of the east coast of Peninsular Malaysia (Choo & Liew, Reference Choo and Liew2005), targeted efforts to survey these communities should be undertaken to better understand seahorse uses in these settings.
In summary, we found that most of the general public and fisher respondents in Malaysia do not use seahorses in any way. A minority reported using seahorses as traditional medicine, ornaments, pets, for spiritual purposes and for research and in educational display materials. However, these findings may not be a true reflection of the level of seahorse exploitation in Malaysia considering the significant involvement of Malaysia in global seahorse exportation (Louw & Bürgener, Reference Louw and Bürgener2020). Socio-demographic variables such as ethnicity, location setting, region, education and gender also play significant roles in shaping the use of seahorses amongst Malaysians. In terms of management implications, culturally specific seahorse uses by the public and fishers had been largely overlooked prior to this study. Future conservation and educational outreach measures should utilize our findings to design socially and culturally appropriate campaigns (Bennett et al., Reference Bennett, Roth, Klain, Chan, Christie and Clark2017; Margulies et al., Reference Margulies, Wong and Duffy2019), setting a precedent for holistic approaches to promoting the sustainable use of seahorses and other marine resources.
