“…Our result indicated that inclusion of soybean oil in feed does not compromise the species growth, suggesting the possible replacement of fish oil with soybean oil in diet formulation for darkbarbel catfish. The positive relationship between tissue fatty acid composition and dietary fatty acid contents has been well demonstrated in previous studies (Bransden et al, 2005;Zia-Ul-haq et al, 2007a, b, 2008, 2011aLuo et al, 2008;Rezek et al, 2010). In this study, the muscle fatty acid composition in fish generally reflected the lipid composition in diets similar to the report of Ng et al (2003) that the high fatty acids in feed can lead to high fatty acids in muscle.…”

An 80 day feeding trial was conducted to evaluate the effects of dietary inclusion of soybean oil to replace fish oil in the diet on growth, muscle fatty acids and immune responses of Pelteobagrus vachelli. Isonitrogenous and isocaloric diets were formulated with four fish oil to soybean oil ratios at 8:0 (FO, control), 6:2 (MO1), 2:6 (MO2) and 0:8 (SO) in triplicate. Each diet was fed to juvenile darkbarbel catfish (1.0 ± 0.02 g) twice daily. No significant differences were found in weight gain, special growth rate, hepatosomatic index and intraperitoneal fat ratio among all the treatments. Incorporation of soybean oil significantly modified the fatty acid composition and n-3 and n-6 PUFAs ratio in muscle of fish. Fish fed MO1 showed significantly higher serum lysozyme activity, complement C3 and C4 contents and total IgM content than those fed other diets. These results indicate that partial replacement of fish oil with soybean oil does not compromise fish growth, but improve fish immunity. This study suggests that 25% fish oil replacement with soybean oil can be used in the practical diet of this fish.

“…In the present study, the hepatic FA profile of yellow catfish generally reflected the dietary FA composition, as pointed out in other studies (Henderson and Tocher, 1987;Bell et al, 2002a,b;Sargent et al, 2002;Luo et al, 2008a). Yellow catfish fed the diet with increasing LNA to LA ratio showed increased proportions of LNA and decreased LA profiles due to their dietary contents.…”

“…Yellow catfish fed the diet with increasing LNA to LA ratio showed increased proportions of LNA and decreased LA profiles due to their dietary contents. In the present study, the ranges for percentages of SFA and MUFA in the liver lipids were narrower than those for dietary lipids, suggesting selective metabolism/retention of some FAs to meet energy demands of the fish (Dosanjh et al, 1988(Dosanjh et al, , 1998Luo et al, 2008a). It should be pointed out that in the present study, LA and LNA were present in all the diets, but there were only traces of HUFA such as AA, EPA and DHA; however, in liver, the absolute amounts of these HUFA were high, considering high hepatic lipid contents in combination with the percentage of these HUFA present, suggesting that yellow catfish are able to elongate and desaturate LN and LNA to their end products, only like other freshwater fish (Sargent et al, 2002;Ruyter et al, 2006;Turchini et al, 2006;Blanchard et al, 2008).…”

“…Therefore, commercial feeds specifically formulated for S. hasta should meet their nutritional needs, improve productive efficiency and decrease phosphorus discharge in order to achieve economical and environmental sustainability. However, to our knowledge, the information concerning their nutrient requirements, particularly the efficiency of mineral utilization from feed and seawater is scarce (Luo et al, 2008). The purpose of this study was to determine the effect of dietary phosphorus on the growth and body component of juvenile S. hasta.…”

The effect of dietary phosphorus on the growth and body components of juvenile Synechogobius hasta was determined. Different percentages of dietary phosphorus (0.63, 0.77, 0.93, 1.06, 1.22 and 1.36) were tested by feeding the fish (body weight, 15.81 g ± 0.32 g; 20 individuals each group; 3 groups each percentage) at a surplus of 5%-10% above satiation for 35 d. Dietary phosphorus did not significantly affect the specific growth rate, feed intake, feed conversion ratio and protein efficiency rate. Nitrogen retention was found to be the highest in fish fed the diet containing 1.06% of phosphorus; however, this was not significantly different from other diets. Fish fed the diet containing 0.93% of phosphorus showed the highest phosphorus retention; similar phosphorus retention rates were found in fish fed the diets containing 0.77% and 1.06% of phosphorus. Fish fed the diet containing the highest percentage of dietary phosphorus were found to contain the least whole body lipid, lower than fish fed other diets (P<0.05). The protein content increased from 18.59% to 19.55% (although not significant) with the decrease of body lipid content (P>0.05). The contents of the whole body ash, whole body phosphorus and vertebrae phosphorus increased with dietary phosphorus percentage up to 1.06 (P<0.05), reaching a plateau after that. Dietary phosphorus did not significantly influence the muscle components (protein, lipid and moisture). Condition factor and hepatosomatic index were the highest in fish fed the diet containing 0.63% of dietary phosphorus; however, this was not significantly different from those of other diets. The second-order polynomial regression of phosphorus retention against dietary phosphorus identified a breakpoint at 0.88% of dietary phosphorus. However, the dietary requirement of phosphorus for maintaining maximum phosphorus storage determined by broken-line analysis of the contents of whole body phosphorus, and ash and vertebrae phosphorus was 1.06% of the diet.
