Use an alternative protein source: animal Sustainable Aquaculture

Between 2007 and 2008, a controlled, randomised, replicated trial in Scotland (Pratoomyot et al., 2011) found that Atlantic salmon fed alternative protein to fishmeal had lower final weights than fish fed a fishmeal diet. The final weight of the groups fed fishmeal diets was 3.8kg compared to between 3.4 and 3.6kg in fish fed alternative protein diets. Five diets were formulated to satisfy the nutritional requirements of salmonid fish; the four experimental diets contained 11% fishmeal and 55% of either wheat gluten, pea protein, blood meal or kidney bean.  A control diet containing 25% fish meal was also given to one group. Two thousand two hundred and fifty Atlantic salmon were fed the experimental diets by automatic feeders for nineteen weeks.
