Carbohydrates are commonly used in aquaculture feed because they are the cheapest energy source. Promoting carbohydrate catabolism for energy production can increase the dietary protein utilization efficiency (i.e., a protein‐sparing effect). Alpha‐lipoic acid (α‐LA) is a cofactor of some rate‐limiting key enzymes (pyruvate dehydrogenase complex and α ...

Three 56‐day feeding trials were conducted to evaluate dietary lipid requirements and effects of dietary lipid levels on growth, digestive enzyme activities, antioxidant capacity, and lipid metabolism in turbot (Scophthalmus maximus L.) at three growth stages. The initial mean body weight of turbot was 9.13 ± 0.17 g, 50.10 ± 0.38 g, and 80.05 ± 0.76 g (

Protein requirement in the diet of Heros severus (Heckel, 1840): An Amazonian ornamental fish
Abstract Two experiments to determine the crude protein (CP) requirement of Heros severus were performed. Five isocaloric (3,200 kcal kg−1 of digestible energy) diets containing five levels of CP (28, 32, 36, 40, and 44%) were evaluated. In the first, 75 fingerlings were distributed among 15 aquaria (30 L).

Digestibility of feed ingredients for the striped surubimPseudoplatystoma reticulatum [PDF]
Knowledge on apparent digestibility coefficients (ADC) is necessary to maximize the feed efficiency, thus lessening dietary nutrient and energy losses. This study tasks the determination of apparent digestibility of selected feedstuff to striped surubim Pseudoplatystoma reticulatum, a carnivorous, South American catfish of economic importance for ...

Most studies in nutrition for the South American catfish (surubim) were limited to the initial phase of development. However, it is clear that performance and nutrient utilization can change during the life stages of a fish.

The use of the so‐called ‘tubs’ for transporting and storing fresh fishery products
Abstract On‐land transport/storage of fresh fishery products (FFP) for up to 3 days in ‘tubs’ of three‐layered poly‐ethylene filled with freshwater and ice was compared to the currently authorised practice (fish boxes of high‐density poly‐ethylene filled with ice).
