This study compared production performance and tissue fatty acid composition of California Yellowtail fed diets containing various saturated lipids.
This study shows that soybean oil can totally replace fish oil in California yellowtail aquafeeds without affecting production performance and reducing the omega-3 fatty acid profile of fish tissues, as long as acceptable levels of ARA and DHA are provided.
Fishmeal sparing in aquafeed is often limited by the presence of anti-nutritional factors found in plant-derived feedstuffs. Fermentation may be a cost-effective means of addressing such factors and improving utilization of plant ingredients in feed.
Fish oil sparing has proven difficult for fish species, like sea bass, that require the long-chain polyunsaturated fatty acids (LC-PUFAs) abundant in fish oil but lacking in most alternative fats and oils used in aquafeeds.
Hubbs-SeaWorld Research Institute developed an integrated larval-nursery recirculating aquaculture system for California halibut utilizing shallow raceways for juvenile culture.
Hubbs-SeaWorld Research Institute and Universidad Autónoma de Baja California are working to produce improved broodstock diets for white sea bass and totoaba.
