Use genetically modified alternatives Sustainable Aquaculture

In 2007, a randomised, replicated, controlled study in Norway (Bakke- McKellop et al., 2008) found no effects on the histology of salmon, Salmo salar, fed diets containing genetically-modified maize and soybean as a substitute protein source for fish meal. Histological examination of the stomach, diffuse pancreatic tissue adjacent to the pyloric caeca, liver, spleen, kidney or thymus that could be attributed to feed composition. Over eight months, fingerling salmon were fed one of seven diets containing maize (two genetically-modified and two standard varieties), soybean (one genetically-modified and one standard variety) and a standard fish meal diet. Fish were removed from tanks were taken for histological screening. The Atlantic salmon used within the experiment were at the parr- smolt transformation stage.
