Evaluation of growout diets with varying protein and energy levels for red drum Sciaenops /ocellatus
The augmentation of nutrient retention and subsequent reduction of effluent waste generated by aquaculture production facilities are important factors in lowering production costs while simulta-neously minimizing pollution and environmental impact resulting from intensive growout culture.
