| Abstract |
Among the Gadus morhua L., Nephrops norvegicus (L.) plays an important nutrition role, especially in the classes with a greater length. Only in August Nephrops norvegicus (L.)is an important component of the diet of Merlangius merlangus. In the line of the research "incidence frequencies" and the average number of species that appear in the remaining stomach contents of the Gadus morhua (L.) and Merlangius merlangius are being summarised in a table. A species list of this is given. This list, however, merely has a faunetic value. From the tables we conclude that juvenile Gadus morhua (L.) feeds itself with small Crustacea and Pisces. Adulte Gadus feed itself more with Pisces and larger Crustacea such as Macropipus holsatus (Fabr.), Corystes cassivelaunus (Pennant) and Eupagurus bernhardus (L.). Merlangius merlangus (L.) feeds itself with small Crustacea, Polychaeta sp. en Pisces |
