Ecology of Dicentrarchus labrax
 
Main Ref. Fischer, W., M.-L. Bauchot and M. Schneider (eds.), 1987
Remarks Eurythermal. Gregarious when young. Voracious predator. High tolerance to salinity changes. Adults migrate to the estuaries in summer where they spawn in January-June. Young inhabit waters of 0.24-0.37% salinity where they feed mainly on zooplankton (Ref.. 11268). From 3.0 cm TL, diet changes to worms, crustaceans, fish larvae. Adults are strictly carnivorous surviving on small fish (Ref. 11243).
