Resumen del producto

Literature on the trophic ecology of small pelagic fish (primarly anchovy Engraulis spp. and sardine Sardinops sagax 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 fi sh from upwelling and temperate nonupwelling ecosystems. Information from morphological studies of the feeding apparatus, fi eld studies on dietary composition and foraging behaviour, and laboratory studies that have provided data for the parameterization of bioenergetic and other models of these small pelagic fi sh are presented, where available. Two or more small pelagic fi sh 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 could be trophically mediated. Linkages between climate and fi sh are described for many of the systems, and possible impacts of climate change on some of the species are described.
