Trans-omics analysis was used to evaluate the differences between cultured and wild female Japanese eels, and possible causes of the ovulation problems frequently seen in cultured females. 

This study evaluated the effects of replacing fishmeal and fish oil with a plant-based diet in juvenile and on-growing rainbow trout from first-feeding. 

This study examined changes in the biochemical composition of the microalga Nannochloropsis sp. cultivated as a potential feedstock for aquafeeds, and presents results on its productivity, protein content and lipid composition. 

Este estudio evaluó el efecto de las dietas suplementadas con aceite de pescado y harina de algas para el enriquecimiento de LC-PUFA en tilapia juvenil del Nilo. Las dietas experimentales son prometedoras como una opción viable para enriquecer el contenido de omega-3 en los filetes de tilapia. 

This study evaluated the effect of diets supplemented with fish oil and algae meal for LC-PUFA enrichment on juvenile Nile tilapia. The experimental diets have promise as a feasible option for enriching omega-3 content in tilapia fillets. 

This study compared production performance and tissue fatty acid composition of California Yellowtail fed diets containing various saturated lipids. 

A significant body of research has demonstrated that regular and increased consumption of essential omega-3 fatty acids can reduce the risk of developing macular disease, providing us with an opportunity to help protect our eyes through proper nutrition and diet. 

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. 

This study assessed the efficacy and nutritional properties of the marine alga Nannochloropsis salina as a feed ingredient using tilapia (Oreochromis niloticus) as a model species. Results showed adequate growth, survival, FCR and enhanced EPA levels. 

Una clave para expandir la acuacultura es encontrar fuentes alternativas de proteínas y aceites. La suplementación o sustitución de aceite de pescado en los alimentos acuícolas con fuentes alternativas de lípidos – semillas oleaginosas, microalgas, insectos y otros - parece posible si se pueden satisfacer los requisitos de ácidos grasos esenciales. 

A key to expanding aquaculture is finding alternative sources of proteins and oils. Supplementing or replacing fish oil in aquaculture feeds with alternative lipid sources – oils seeds, microalgae, insects and others – appears possible as long as essential fatty acid (EFA) requirements are satisfied. 

This 10-week feeding trial aimed at complementing existing information on largemouth bass responses to oils with supplemental EPA and DHA. Dietary supplementation of these essential fatty acids may be required in feeds for this species. 

Green water, which describes the typical water color in tropical aquaculture facilities, consists mainly of various phytoplankton species along with bacteria, protozoa and zooplankton. It is relatively easy to produce without any supplemented nutrients. 

The results of this study provide the first comprehensive evidence of the significant impact of dietary oils with different fatty acid class profile on the in vivo fatty acid metabolism of tilapia. 

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.
