Feeding Chronology of Yellowtail Flounder (Limanda ferruginea) and American Plaice (Hippoglossoides platessoides) on Grand Bank (NAFO Division 3N)

A total of 1199 individuals of yellowtail flounder (Limanda ferruginea, Storer) and 970 individuals of American plaice (Hippoglossoides platessoides, Fabricius) were sampled from six hauls carried out in a period of 24 hours for studying the feeding chronology of these species. The main prey of yell...
