Project Number: 5366-21310-004-01
Start Date: Jun 01, 2008
End Date: May 31, 2012
A series of experiments will be conducted to determine nutrient and energy availability of both conventional and innovative plant protein feedstuffs to steelhead trout, cobia and red drum. Based on this information, additional feeding trials will be conducted to optimize amino acid balance of the most promising alternative protein diets through ingredient blending and amino acid supplementation. The effects of these various dietary manipulations will be evaluated in terms of product quality, health and stress tolerance of the various fish species. Enhancement of growth and amino acid retention efficiency also will be evaluated with Atlantic salmon by feeding complementary, amino acid-deficient and -enriched diets alternatively to up-regulate absorption of amino acids to increase protein synthesis and growth. A demonstration trial with industry collaborators also will be conducted to evaluate the effects of alternative protein diets on fish production, health and product quality of trout based on information developed in objectives 1-4. Finally, a workshop to inform producers of the potential for alternative protein diets will be held with results from the project being presented by all participating investigators.
