Un estudio evaluó el valor nutricional de los peces de carne blanca cultivados vs. silvestres usando lobina rayada hibrida, lobina de boca grande y peces agallas-azules. Los resultados mostraron que los peces de carne blanca cultivados son tan valiosos desde el punto de vista nutricional – y en algunos casos, más – como los peces silvestres.

A study assessed the nutritional value of farmed vs. wild white-fleshed fishes using hybrid striped bass, largemouth bass and bluegill. Results showed that farmed, white-fleshed fish are as nutritionally valuable – and in some cases, more so – than wild fish.
Aquafeeds
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.
Aquafeeds
In a study of juvenile cobia diets, results suggested that lipid sources with high levels of saturated fatty acids and low polyunsaturated fatty acids can replace a large percentage of fish oil in feeds if they are amended with DHA.
Health & Welfare
The absence of practical immediate-release sedatives for fish jeopardizes fish, fisheries, fish culture and research, posing risks to aquatic resources as well as those handling fish.
Aquafeeds
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.
