Previous research on the Florida pompano successfully demonstrated an increased use of soybean meal and soy protein concentrate in formulated feeds. Fish meal can be replaced with other animal proteins at equivalent levels of inclusion. This project specifically evaluated the use of PepSoyGen from Nutraferma, a functional soy protein manufactured using fermentation processes. This research compared squid meal and squid hydrolysate as a nutrient source and palatability enhancer for soy-based diets. PepSoyGen may not contain enough methionine to meet dietary requirements, but it may have the potential advantage as a functional ingredient, which may have probiotic-type effects to improve digestibility and growth performance of aquatic animals.
