Abstract

We conducted a 16-week feeding trial with juvenile red drum (Sciaenops ocellatus). Four diets were randomly assigned to six replicate tanks per treatment. A Basal Diet (Diet 1) contained 19.60% fishmeal and 21.42% poultry meals as primary protein sources. Three isonitrogenous (44.5% protein) and isolipidic (14.1% lipid) extruded diets were formulated to compare a fish meal-based diet with diets using alternative protein sources. Two alternative diets were formulated reducing the fishmeal to 0.61% by substituting poultry meals (33.85%) and soybean protein concentrate (11.55% in Diet 2 [Low Fish Meal] and 11.70% in Diet 3 [Low Fish Meal + Additives]). Diet 3 also included Allzyme Vegpro® and Allzyme® SSF at 0.04%. Diet 4, a "natural" diet consisting of chopped cigar minnows, squid, and Pacific white shrimp was used as a positive control. We found that substituting 97% of the fish meal in a standard prepared diet with other protein sources did not affect the growth rate, survival, or health of red drum and improved the assimilation of Phosphorus and reduced the amount released to the environment. The control "natural" diet established the performance potential of the culture system and identified clear performance benchmarks that future feeds development work should target.
