The aquaculture industry is exploring alternative fish feed options to address disease management challenges. A study was conducted on Gilthead seabream, using a control diet of 15% fishmeal and 7% fish oil. The diet was then replaced with a combination of poultry by-product meal and insect meal, and fish oil was completely replaced with microalgae oil, poultry by-product oils, and salmon by-product oils. The immune response of sea bream was analyzed using immunohistochemistry techniques. Results showed no significant differences in IgT+ B lymphocytes and CD3+ T lymphocytes between the two diets. However, a significant increase in eosinophilic granular cells (EGC) signal was observed in seabream fed the alternative diet. The study also revealed that genetic selection increased the number of IgT+ B lymphocytes in the higher genetic growth group (HG) compared to the lower growth group (LG) in sea bream fed the alternative diet.
