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.
El estudio evaluó el rendimiento de producción y la composición de tejidos de pámpano juvenil de Florida alimentado con dietas que contenían aceite de pescado o mezclas 25:75 de aceite de pescado y varias otras fuentes de lípidos.
Study evaluated production performance and tissue composition of juvenile Florida pompano fed diets containing fish oil or 25:75 blends of fish oil and various other lipid sources.
The availability of a cost-effective grow-out feed formulation is an ongoing bottleneck for the expansion of cobia production. Studies by the authors show that the development of an aquafeed with limited or no fish oil content is possible.
A study assessed the growth performance and fillet fatty acid composition of juvenile hybrid striped bass that were fed various diets containing different levels of fish oil, soybean oil, and blends of both. Results suggest that alternative lipid composition influences
Anecdotal information has suggested that pond-reared hybrid striped bass are more vulnerable to transportation-related stressors than cage-reared fish. Study results suggested that accumulation of carbon dioxide and decreasing pH levels may contribute to this phenomenon. Agitation during simulated transport mitigated
The quality flesh and striking coloration of Atlantic spadefish suggest potential in both seafood and ornamental markets. To identify appropriate feeding rates and frequencies, the authors evaluated juvenile spadefish fed daily at varying regimens.
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.
By feeding different oils at different points in a fish's life cycle, such as finishing feeds, farmers can tailor the composition of fillets to maximize value and minimize fish oil use.
