Nutritional condition of anchovy Engraulis encrasicolus larvae in connection with mesozooplankton feeding catabolism in the southern Bay of Biscay, NE Atlantic
The study examines the spatial variations over the French continental shelf of the southern Bay of Biscay (North-East Atlantic) in the nutritional condition of anchovy (Engraulis encrasicolus L.) larvae which was estimated through their DNA/C index. The same cruise yielded quantitative estimates of...
