Boasting a bright red-orange and oil-rich fillet like salmon, trout can be grown to market size faster and are often less expensive. 

Tokyo University researchers have learned to spawn fish from germline stem cells in vitro, a method that can be deployed to help endangered species. 

MicroSynbiotiX is employing the power of transgenic microalgae to make it cheaper and easier for aquaculture producers to administer vaccines to fish. 

Because paper trails aren’t perfect, some food producers are going beyond written or digital records to prove their products’ authenticity and prevent economic fraud. Is farmed seafood a perfect fit for forensic-science traceability? 

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. 

What started out as a simple yet ambitious contest to drive innovation in the aquafeed sector has evolved into a fully global competition – and collaboration – amongst ingredient suppliers and feed manufacturers.  

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. 

The technical director for the U.K. seafood industry authority, Seafish, talks to the Advocate about the challenges facing aquaculture expansion and why it will be seafood that fills the protein gap that many are expecting in the future. 

Recent surveys indicate that global finfish production has doubled over the last decade, but most of this growth happened in the first half of this period. Production is still growing but at slower pace than in recent years, and annual growth rates must increase to at least 7.2 percent to maintain the double-in-a-decade objective. 

Russia’s 2014 embargo on seafood and other food imports from the United States, European Union members and other countries created multiple impacts. Russian consumers have experienced higher prices and declines in the volume and quality of seafood available. Russian companies in seafood value chains have also been hurt. 

Cathepsin D alone and in combination with other cathepsins presents the greatest proteolytic activity on some fish muscles. 

A study was performed to determine the effects of puerarin, a biologically active ingredient in the roots of kudzu, on stress modulation in farmed salmon. 

Germany produces a limited amount of carp, trout, mussels and other species. Although traditional pond-based farms continue to operate, the country’s aquaculture production is trending toward land-based systems that feature efficient resource use and reduced environmental impacts. 

Integrated aquaponic operations can improve water use efficiency because plants participate in nitrogen and phosphorus removal and integration. 

Alternative lipids have achieved varied success in ensuring adequate growth and fatty acid composition in fillets. The authors evaluated rainbow trout raised on diets containing fish oil or a blend of fish and standard or modified lipids varying in fatty acid composition.
