Summary

Introduction

The world's oceans have been exploited for generations. In some cases, this has led to the removal of top predators from ecosystems, resulting in a cascading effect through trophic levels altering ecosystems and restructuring food webs (Pauly et al., 2002; Myers & Worm, 2003). Cetaceans (whales, dolphins and porpoises) have also been targeted, mainly for their meat and oil, and some populations being driven close to extinction. Fortunately, attitudes towards cetaceans have changed over the past two decades, and rather than harvest them, it is now more desirable to observe them in their natural environment (Bearzi et al., 2010). Today, cetaceans are icons for marine conservation efforts. The USA was the first country to introduce legislation to protect marine mammals through the Marine Mammal Protection Act 1972 (MMPA). The MMPA was designed to minimize the capture or ‘take’, harassment and disturbance of marine mammals, primarily from fishing operations as by-catch and from cetacean hunting. The MMPA defines the term ‘take’ as ‘hunting, killing, capture and harassment of a marine mammal or the attempt thereof’. Since the declaration of the MMPA, other countries have adopted their own legislation, e.g. The Marine Mammals Protection Act 1978 in New Zealand and the Environment Protection and Biodiversity Conservation Act 1999 in Australia.
