| Abstract |
The importance of predation by the whiting from the Celtic Sea has been studied by analysis of stomach contents. Eight hundred and thirteen whitings have been examined during 1984-1986 period. Fish food totalizes 97% of food. It is chiefly swimming species (poor-cod, Norway pout, clupeidae and blue whiting); no cannibalism has been observed. The daily food indice varies between 2 and 4% according to the length and the annual consumption on fishes of nominal catches (11.230t for 1983) would reach 135.000t corresponding to species already fished for human consumption and meal industry. |
