    • Growth data - Development and optimization of grow out diets for sablefish (Anoplopoma fimbria)

    Metadata Updated: May 24, 2025

    Our experience with juvenile sablefish and long term rearing of broodstock indicate that salmon grower feeds currently used by commercial sablefish farmers for grow out are not optimally formulated to support maximum growth and efficient feed conversion. However, there are no published studies examining the effects of dietary nutrient balance on productive performance and growth at any post larval life-history stage for this species, and there are currently no commercial diets specifically formulated for sablefish in the marketplace. Because of the large impact of feed cost on the economic viability of farming sablefish, we are focusing on grow out diets intended for use during the post larval stages of development when the fish are being reared to harvest size. In this research, we use a novel statistical mixture model and response surface analysis method to determine the optimal level of dietary protein, lipid and digestible carbohydrate for testing. This approach permits simultaneous testing of diet formulations encompassing the full range of protein, lipid and digestible carbohydrate that can be produced commercially using today’s most advanced extrusion feed manufacturing technology. Fish in experiments may be PIT tagged and regularly checked for growth in length and weight.
