Resumo: | This studyaimed to evaluatechangesin body composition, speciallymuscleandliver fatty acid profileinmeagre (Argyrosomus regius) fed with different dietary lipid sources and levels, with or without selenium supplementation. Six hundred meagre were fed twice a day, 6 days per week, with eight experimental diets for 60 days. Diets were a combination of fish oil or a vegetable blend (45% linseedþ 35% rapeseedþ 20% soybean oil), at 12 or 17% of oil and 0 or 1 mg/kg of organic selenium, in a 2 2 2 factorial design. The whole body protein and lipid content were affected by the dietary oil source. Fish oil diets increased long-chain (LC) PUFAs content in the edible tissues, while vegetable oil-based diets increased short-chain (SC) PUFAs. Vegetable oil diet tended to decrease thefish proteincontent.A higherlipidlivercontentwas observedinmeagre fed the vegetable oil blend. The results also suggested the ability of meagre to convert SC-PUFA to LC-PUFA when the vegetable oilisincludedin their diet. The possibility for partial substitution offish oil by vegetable oilin meagre diets, resulting in lower dependence of fish oil in meagre farming, is also demonstrated here |
