A controlled, replicated study in Western Norway (Sissener et al., 2009) found similar overall in final weight and growth rate between Atlantic salmon that were fed diets containing genetically modified and non- genetically modified soybeans. However, one of four sampling periods found that growth rate was lower in genetically modified fed fish (0.74 compared to 0.85). Another sampling period found the genetically modified fed fish to be heavier (98.3g) compared to the salmon fed standard soybean meal (93.5g). Over seven months, salmon (average initial weight 40g) going through the parr–smolt transformation, were fed experimental diets: a non-genetically modified soybean diet (control) and two diets with genetically modified soybean meal included at a 25% and 26.2% level. Fish meal was the main source of protein in the diets. Growth rates and weights were measured. The trial began in July with four experimental sampling dates in September, December and the beginning and end of February.
