Partial Replacement of Fish Meal with Laver Porphyra spp. in Diets for Atlantic Cod
Juvenile Atlantic cod Gadus morhua (initial mean weight +/- 15.6 g) were fed three isonitrogenous, isocaloric diets (55%, protein, 16% fat; calculated gross energy approximate to 20.5 MJ/kg) containing dried laver (nofi) Porphyra spp. (red algae) to replace 0, 15, aid 30% of the fish meal in a comme...
