英文摘要: Abstract(#br)Silver barb ( Puntius gonionotus ) is considered as a promising medium-sized carp species for freshwater aquaculture in Asia. This study in silver barb was carried out to evaluate the effects of increasing dietary levels of lipid on growth, nutrient utilization, whole-body composition, tissue fatty acid composition and Δ6 fatty acyl desaturase ( Δ6 fad ) gene expression. Fish (11.3 ± 0.23 g of initial body weight) was fed for 60 days with five experimental diets: FO-0 (control feed); FO-30; FO-60; FO-90 and FO-120 containing 0, 30, 60, 90 and 120 g fish oil kg −1 diet, respectively. Among the diets, the highest specific growth rate (SGR), protein efficiency ratio (PER) and whole-body lipid content, and the lowest feed conversion ratio (FCR) were recorded with FO-120 diet. The...
