摘要

Four diets were formulated to determine the effectiveness of supplementing a commercially available protein source (Pro-Pak(R) from H. J. Baker and Brothers, Inc.) for menhaden fish protein (Special Select(TM) from Zapata Haynie Corp.), in diets for red drum Sciaenops ocellatus. The diets were formulated to be isonitrogenous, each contained 45% total protein. Protein from soybean meal and wheat gluten was kept constant; Pro-Pak replaced 0, 25, 50, or 75%?o of the menhaden fish meal on an equal protein basis. In the first 8-week growth trial, which used satiation feeding, positive results from high fish meal diets were observed; percent weight gain ranged from 630 to 830%, and there was near 100% survival. In a basal diet containing 40% fish meal, the replacement of 50% of the fish protein with Pro-Pak resulted in minimal changes in growth and feed consumption. The replacement of 75% of the fish protein in the basal diet (diet 4) resulted in reduced performance of the fish. The second growth trial confirmed reduced growth rates of fish fed diet 4 under fixed feeding conditions, confirming nutritional differences between the test ingredients. Based on the results of this study, with appropriate restrictions, Pro-Pak should be considered an acceptable ingredient in practical diets for red drum.
