| Abstract: | Three levels of gelatinized wheat, 70, 140 and 210 g kg?1, were included in diets for Atlantic salmon, Salmo salar, L., of mean initial weight around 270 g. The experiment was run for 10.5 months and there was an eight- to nine-fold increase in fish weight. No significant differences in weight increase were found between fish. No negative physiological effects, such as hyperglycaemia or excessive hepatic glycogen accumulation were observed. Concentrations of pancreatic hormones were not affected by diet, but positive correlations were found between glucagon-like peptide (GLP) and glucagon, and between insulin and glucagon. Gelatinized wheat in diets for Atlantic salmon did not seem to affect organoleptic traits of the fish flesh in any undesired way. |
