Abstract: Low fish meal diets have been a hot-button topic in the animal industry, including the aquafeed industry. Furthermore, as enterprises worldwide focus on sustainable businesses, they must be adapted using alternative protein feedstocks in animal feed. Therefore, this research was interested in the zero percent fish meal with high soybean meal diets and supplementing it with trace minerals, compared to 15 percent of fish meal diets on growth and health of Pacific white shrimps (Litopenaeus vannamei). The trial was assigned in nine treatments and each of ten replicates. Nine diets were formulated to contain 36 percent crude protein while varying in the fish meal inclusion levels (15, 7.5, and 0%) and trace minerals-amino acid complex levels (0.06, 0.12, and 0.18%). Ten replicated groups of shrimps were fed one of the nine test diets for eight weeks. Adjustment of trace minerals inclusion in fish mealfree diets from 0.06 to 0.12 percent reversed final body weight and specific growth rate back to the level registered with the 15 percent fish meal diet. Notably, significantly increased proteinase, lipase activity, glycogen composition, total hemocyte count, phenoloxidase activity, and improved microvilli height (P<0.05). Interestingly, the nutrient content in shrimp muscles was not affected by the recipe's reduction in fish meal. It indicated that no shrimp batch is malnourished due to the different recipes. For nitrite and stocking density stress conditions, the color quality of lower-density shrimp had a significantly higher reddish value and had a much higher survival rate than shrimp raised at a higher density (P<0.05). The challenge test with Vibrio parahaemolyticus found a slight hemocyte infiltration in the hepatopancreas cells, but it was not so severe that the shrimp died. In contrast, mortality was found in nine WSSV challenge test treatments (P>0.05). Therefore, an increase of trace mineral-amino acid complex concentrations at 0.06 percent in the 15 percent fish meal diet and 0.12 percent in the 7.5 and zero percent fish meal diets is enough to promote growth performance and improve immune responses.
