A two-year grant of $276,000 seeks to improve the nutrition of live feed for, and therefore the production of, larval California yellowtail and halibut, with the hopes that the technology will be applicable to other species. 

With all eyes on Japan for the 2020 Olympic Games, leading advocates for responsible aquaculture there see a key opportunity to make stronger sustainability commitments. 

New U.S. policies for offshore aquaculture permitting will soon be put to the test in the Gulf of Mexico. With imported products dominating the U.S. seafood landscape, some argue the time has come for the industry to take a leap forward. 

Boasting ample areas for aquaculture and a robust domestic demand for seafood – not to mention its close proximity to the U.S. market – a land of opportunity lies in Mexico. Fish farming is primed to meet its potential south of the border. 

After 14 years with the USDA’s Agricultural Research Service, Rick Barrows talks about the importance of finding ‘complete’ and commercially viable alternative sources of omega-3 fatty acids and continuing innovation in the aquafeed sector. 

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. 

The University of the Canary Islands in Spain is researching yellowtail broodstock management and larval rearing to promote aquaculture diversification in Europe. 

In a trial, lipid oxidation and metmyoglobin formation in the dark meat of yellowtail during chilled storage were significantly controlled by feeding mushroom extract to the fish as a supplement.
