Add vitamins to food to improve fish immunity
According to research conducted by the Beppu Fisheries Research Institute on the West Coast of the United States, adding appropriate amounts of vitamin C to foods can activate the immune response functions of the fish, thereby increasing the immune capacity of the fish. The experiment was to add 1 gram of vitamin C per kilogram of regular diet, and grouped with rafts, rainbow trout, and Atlantic salmon to compare 10 consecutive cycles. The results showed that the group fed with vitamins was significantly more resistant to infection than the control group. The anatomical samples also showed that vitamin C in the diet can activate the macrophage activity of Atlantic salmon, further stimulate the differentiation of lymphocytes, and increase Fish immunity.
