Diet of Flemish Cap Cod with Particular Reference to Predation on Radish: 1988-93

21 páginas, 5 figuras, 8 tablas.-- Scientific Council MeetingThe food and feeding of Flemish Cap cod in summer are described for six years utilizing 3315 stomachs. The feeding intensity was high and the Fey spectrum was narrow in all years. Hyperiids and redfish stand out in the diet of Flemish Cap cod, Illex illecebrosus and polychaetes had a high annual variability. Invertebrates (crustaceans and polychaetes) were dominant in juvenile cod diets, while the most important prey in adult cod was fish, mainly redfish. The cannibalism rate has strong year to year fluctuations on the Flemish Cap. There is a positive relation between predator size (cod) and prey size (redfish). The Condition Factor variation is closely related with the predation intensity on Sebastes. A change in the diet composition is observed in the last two years. This change consisted of an increase of hyperiids in the adult cod diet and a decline of Sebastes sp.Peer reviewe
