    • Composition of fish and feeds - Developing diets and feeding strategies for improved growth and performance of juvenile and adult sablefish

    Metadata Updated: May 24, 2025

    Feed costs and time to harvest are key factors affecting the economic viability of domestic sablefish (Anoplopoma fimbria) aquaculture. Use of fast growing all-female monosex stocks dramatically reduces time to harvest, but our research to date indicates that the commercial salmon feeds typically used by industry are not optimally formulated for sablefish and there is still a high degree of potential for improved growth and feed conversion. The effects of dietary balance of protein, fat, and carbohydrate on productive performance, growth and feed conversion at any post-juvenile stage of development are unknown, and there are no commercial diets specifically formulated for sablefish aquaculture in the marketplace. Dietary nutrient imbalances combined with inappropriate feeding schedules and strategies contribute to poor nutrient utilization and are unlikely to fully support the growth potential of this species, impeding continued efforts to improve performance during grow-out to harvest. Thus, research activity focuses on establishing performance optimized diets and feeding strategies that support maximum growth, efficient feed conversion and other economically important traits such as fillet yield. Information on proximate composition of fish and tissues and aqua feeds and of feed constituents and selected fish tissues.
