Large kelp is the main source of alginate in the EU and comprises the majority of harvested seaweed in Norway. The inclusion of 5 percentage seaweed in diets will also give insights on growth performance of salmon.
Feed meal with 5 percent macroalgae
"We have put the brown seaweed, large kelp (stortare in Norwegian) and two bioactive compounds extracted from this seaweed into salmon diets. The diets also contain some soybean meal that is known to cause inflammation in the salmon gut, a condition referred to as soybean meal-induced enteritis. In this way, soybean meal serves as a good challenge model when we are investigating health-beneficial effect of the seaweeds. After the end of the experiment we will collect samples from the intestine and some other tissues of the fish to see if the macroalgae and bioactive compound have any preventive effects on soybean induced enteritis,” Keihani explains.
