Description :
Anchovies ana sardines are iisnes of great importance as for much of the last decades they accounted for 30-40% by weight of all marine fishes for which records are available. They occur together in commercial quantities in temperate marine areas throughout the world's oceans. Apart from being commercially and socially significant their populations occupy crucial positions in the oceans1 ecosystems. Low in the food chain, clupeoids tend towards abundance, as if their purpose in life was to be eaten and fuel the upper levels of marine trophic chains! The present book covers a broad spectrum of topics on the biology (systematics, phylogeography, reproduction, feeding) and ecology (habitat characterization, recruitment variability) of anchovies and sardines. It also puts together important information on the state of theirfisheries, exploitation and management.
