The foundation of the method for estimating feeding using gastric evacuation studies lies in
the input= output rule. More complex models may have specialized uses, for example where …

The gastric evacuation rates of brown trout Salmo trutta (0.9–1.6 kg) feeding on fingerling
rainbow trout Oncorhynchus mykiss (3.5–7.6 g) were measured in the laboratory at five …

Groups of cod were fed two natural prey types, prawn and herring, and two herring-based
wet diets, one with low and the other with high energy density. Cod fed upon whole herring …

Metamorphosis in cod, Gadus morhua L., was investigated with respect to morphological
changes in the alimentary tract (mouth, stomach and pyloric caeca) and external characters …

No effect of prey size on gastric evacuation rate was found in whiting Merlangius merlangus.
Prey energy density explained most of the data variation among fish prey, and evacuation …

Growth, nutrient utilisation and gastrointestinal evacuation time using different fish meal
particle sizes and dietary protein concentration was examined in Atlantic salmon. Salmon …
