Abstract Over the past 20 years, substantial progress has been made in improving feeds and feeding technologies for most aquaculture species. Notable improvements feed conversion efficiency (through a better understanding of requirements improved management) ingredient sustainability increased capability to use wider range ingredients) have achieved. While advances many main species, there is still much be done defining requirements, especially species being farmed developing world. Gains...
Abstract Vitamin E (VE) is composed of a group fat‐soluble molecules, from which the most active homologous α‐tocopherol. VE structural component cell membranes with potent chain‐breaking antioxidant action, plays main role in several biological processes. In cultured fish, can prevent peroxidation cellular and subcellular membrane phospholipids also red blood cells, leading to maintaining functional integrity animal cells. performs other metabolic functions, including improvement immune...

To assess juvenile meagre, six isolipidic, isoproteic, semi-purified diets with different levels n-3...
Vitamins D and K are essential fat-soluble nutrients that intervene in bone development processes among other biological functions. The present study is aimed at investigating the potential combined effect of dietary supplementation with vitamin D3 (cholecalciferol) K3 (menadione) gilthead seabream (Sparus aurata) larvae. For purpose, diets were supplemented different combinations D3/vitamin (mg/kg diet) as follows: 0.00/0, 0.06/70, 0.06/170, 0.13/70, 0.13/170, 0.40/70, 0.40/170. Feeding...
To sustainably produce marine fish with a high lipid quality rich in omega-3 fatty acids, alternative sources of eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) are being identified. Moreover, the use bioactive compounds that would stimulate vivo synthesis, such as resveratrol (RV), reduce dependence on oil aquafeeds. Gilthead sea bream (Sparus aurata) were fed four experimental diets combining two levels (6% dry matter (DM); 2% DM) or without 0.15% DM supplementation (F6, F2, F6 + RV,...

An effective replacement for fish meal (FM) and oil (FO) based on plant-based raw materials in the feed of marine species is necessary sustainability aquaculture sector. However, use to replace FM FO has been associated with several negative health effects, some which are related oxidative stress processes that can induce functional morphological alterations mucosal tissues. This study aimed evaluate effects dietary oligosaccharides plant origin (5,000 ppm; galactomannan oligosaccharides,...
Modern aquaculture feeds tend to contain lower levels of fish based ingredients, while increasing the content plant ingredients. However, this may alter vitamin profile feeds, leading unbalanced supply. Requirements for several vitamins have been established species such as carps and salmonids, but adequate gilthead sea bream are yet unknown. Vitamin D is mainly involved in Ca homeostasis by regulating uptake liberation from bone intervening remodeling. Fish unable synthesize so require...
Genetic improvement of feed efficiency is key to improve the economic and environmental sustainability fish farming.
