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

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.

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle.
