Nutrição do Surubim (Pseudoplatystoma spp) e seus híbridos – revisão de literatura / Nutrition of Surubim (Pseudoplatystoma spp) and its hybrids – literature review

open access: yesBrazilian Journal of Animal and Environmental Research, 2021
As espécies do gênero Pseudoplatystoma e seus híbridos vêm se consolidando no mercado aquícola brasileiro, devido ao alto valor comercial e a sua boa aceitação no mercado, basicamente em função de uma carne com sabor pouco acentuado, textura firme, coloração clara, baixo teor de gordura e ausência de espinhas intramusculares.

Protein‐Sparing Effect of α‐Lipoic Acid in Diets with Different Protein/Carbohydrate Ratios for the Oriental River Prawn, Macrobrachium nipponense

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
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 ...

Effects of Dietary Lipid Levels on Growth, Digestive Enzyme Activities, Antioxidant Capacity, and Lipid Metabolism in Turbot (Scophthalmus maximus L.) at Three Different Stages

open access: yesAquaculture Nutrition, Volume 2022, Issue 1, 2022., 2022
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

open access: yesJournal of the World Aquaculture Society, Volume 52, Issue 2, Page 482-495, April 2021., 2021
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).

Performance and nutrient utilization in South American juvenile catfish Pseudoplatystoma spp. weighting 89 - 170g, fed at different energy and protein levels

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
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.
