Summary
Abstract
The northwest Atlantic has had a rich history of living marine resource exploitation. As stocks have undergone sequential depletion with some dramatic instances of stock declines in this region, there have been calls for evaluating and improving approaches to managing our use of these resources. As part of these calls and along with recognition that there are broader issues to consider when managing a fishery, the need for more holistic ecosystem-based approaches to manage living marine resources (LMRs) have been increasingly recognized. Here we present a history of LMR management for both Canadian and US waters. We also provide contextual information for the major ecosystems in this region, with synopses and descriptions of major biophysical features in the northwest Atlantic. After noting the main data sets in this region, we discuss some of the major ecosystem models produced by our institutions. Finally, we discuss current efforts to implement ecosystem-based marine fisheries management in the northwest Atlantic.
Introduction
There have been numerous prescriptions and admonitions to implement an ecosystem-based approach to the management of fisheries (EBMF; Larkin 1996, Link 2002a, 2002b, Garcia et al. 2003, Browman and Stergiou 2004, 2005). There have been relatively few instances where such an approach has been implemented to any significant extent (Pitcher et al. 2009), but the number is growing as fisheries scientists, managers, and stakeholders grapple with the specific details of how to do EBMF. As a discipline, and as a practice, we are now moving beyond the “whys” and “whats” of EBMF (Murawski 2007) and squarely facing the “hows.”

Summary
Summary
Literature on the trophic ecology of small pelagic fish (primarly anchovy Engraulis spp. and sardine Sardinops spp. but including the genera Brevoortia, Clupea, Sardina, Sprattus, and Strangomera) and their interactions with plankton are reviewed using case studies describing research on some economically and ecologically important small pelagic fish from up-welling and temperate non-upwelling ecosystems. Information from morphological studies of the feeding apparatus, field studies on dietary composition and foraging behaviour, and laboratory studies that have provided data for the parameterization of bio-energetic and other models of these small pelagic fish are presented, where available. Two or more small pelagic fish species are described in each case study, and disparities in trophic dynamics between co-occurring anchovy and sardine are consistently seen, supporting the hypothesis that species alternations between the two species could be trophically mediated. Linkages between climate and fish are described for many of the systems, and possible impacts of climate change on some of the species are described.
Introduction
Small pelagic fish are, in general, microphagous planktivores, and their high abundance levels in upwelling systems, in particular, was attributed to their ability to feed directly on phytoplankton and hence benefit from a short and efficient food chain (Ryther, 1969; Walsh, 1981). This two-step food chain hypothesis, with small pelagic fish being regarded as essentially phytophagus and feeding on large, chain forming diatoms such as Chaetoceros and Fragilaria (Yoneda and Yoshida, 1955; Bensam, 1964; Loukashkin, 1970; King and Macleod, 1976) was initially well supported (Longhurst, 1971; Durbin, 1979; Walsh, 1981).

Nanoparticle chain aggregates (NCA) of 7 nm titania particles stretch under tension, and contract when the tension is relaxed. The NCA were stretched across expanding holes produced in the carbon film on an electron micrograph grid. After stretching up to 90%, the NCA broke loose at one end and contracted to a tightly folded chain. This pattern was observed in repeated tests. Mechanisms for this behavior and reasons for its generality are proposed. Implications are discussed for the ductility of nanoparticle ceramics, and the improved properties of rubber due to nanoparticle additives.
