Food and Feeding Chronology of American Plaice (Hippoglossoides platessoides) in the North Atlantic
Food and feeding of 5592 individuals of American plaice (Hippoglossoides platessoides, Fabricius) was examined from Grand Bank (NAFO Divisions 3NO), Flemish Cap (NAFO Div. 3M) and Svalbard Area (ICES Div. IIb). Differencies in diet composition were observed by areas. Feeding intensity was higher on...
