“…However, a clear positive relation was not found between fish growth and dietary lipid level [8,9]. Furthermore, the growth of the fish was negatively correlated with dietary lipid at levels of 6-26%, and the best growth was obtained for fish fed the lowest lipid diet in our recent study [10]. One of the most important roles of fish oil in an aquaculture diet is as a source of essential fatty acid, especially highly unsaturated fatty acid (HUFA), and the effect of dietary HUFA level on the growth was examined for several fish species in relation to the availability of vegetable oils [11][12][13][14][15][16].…”

“…Thus, this fish has been shown to utilize dietary carbohydrates successfully as an energy source. A protein-sparing effect of dietary lipid was also reported, and increasing dietary pollack liver oil improved feed efficiency and PER [8][9][10]. However, a clear positive relation was not found between fish growth and dietary lipid level [8,9].…”

Effects of dietary fatty acid composition on the growth of the tiger puffer Takifugu rubripes were examined. Eight experimental diets were formulated with fish meal and casein as the major ingredients, providing 45.0-48.2% crude protein. Pollack and squid liver oils were used for the control diet while experimental diets contained three levels of EPA-DHA concentrated (C-HUFA) oils, soybean oil, linseed oil, and combinations of them, providing 0.5-5.5% n-3 HUFA and 5.0-11.1% crude lipid. Triplicate groups of fish with a mean body weight of 18.7 g per dietary treatment were fed the diets twice daily to apparent satiation, 6 days per week for 8 weeks. The final body weight and weight gain of the fish fed the soybean oil diet without C-HUFA oils were significantly lower than those fed the control diet. Both parameters were not statistically different among the other dietary groups, although the values obtained for the linseed oil diet without C-HUFA oils were lower. Similar trends were seen for SGR and feed efficiency. However, significantly lower PER values compared to the control were observed for the lower C-HUFA and the vegetable oil without C-HUFA oil groups. These results indicate that tiger puffer can be produced successfully with diets containing more than 1.5% n-3 HUFA.

“…Little information is available about effect of quercetin on blood lipid levels in aquatic animal. It is well known that increasing blood lipid levels is always considered to be signs of declining health condition of the cultured fish (Kikuchi et al, 2009). The high blood lipids level might cause accumulation of hepatic triglyceride and cholesterol and form the fatty liver disease (Quesada et al, 2009).…”

This trial was conducted to investigate the effects of supplementary quercetin on growth performance, serum lipids levels and whole fish body composition in tilapia (Oreochromis niloticus). Four hundred fish were randomly divided into five treatment groups with four replicates in each group and 20 fish in each replicate. The dietary quercetin levels of the five treatment groups were: 0 (control group), 200, 400, 800, and 1600 mg/kg, respectively; the trial period was 7 weeks. Compared with the control group, specific growth rate and condition factor of quercetin groups were improved significantly (P<0.05). No significant differences in feed conversion rate and survival rate were found between the control group and all quercetin groups (P>0.05). The triglyceride concentration in serum was decreased significantly with the increasing levels of quercetin supplementation (P<0.05), while the highdensity lipoprotein cholesterol concentration was increased significantly by the supplementation of quercetin (P<0.05). The significant difference of low-density lipoprotein cholesterol concentration was found only between control group and highest dietary quercetin level group (P<0.05). The levels of moisture, crude protein and crude lipid of whole fish body were significantly affected by the supplementation of quercetin (P<0.05), the ash levels of all groups were similar (P>0.05). In conclusion, we demonstrated a promotion of growth performance and the reduction of lipid levels in serum and whole fish body with the supplementation of quercetin.

“…12.1% of dietary lipid is sufficient to achieve the highest protein utilization by O. marmorata juveniles. This lipid level of O. marmorata juvenile is comparable to the other carnivorous fishes European seabass Dicentrachus labrax requires an optimum level of 12% (Peres and Oliva-Teles, 1999); tiger puffer Takifugu rubripes requires less than 11% of dietary lipid (Kikuchi et al, 2009); white sea bream Diplodus sargus requires less than 9% (Sá et al, 2008) to achieve optimum growth. It should be noted that no improvement on the growth performance of tiger puffer (Kikuchi et al, 2009), white sea bream (Sá et al, 2008) and European seabass (Peres and OlivaTeles, 1999) was observed when they were fed with dietary lipid level beyond their optimum lipid levels.…”

“…On the contrary, limited or no protein sparing effect is also reported in many fish species such as grass carp Ctenopharyngodon idella, tiger puffer Takifugu rubripes and turbot Psetta maxima where increasing levels of dietary lipid did not bring any beneficial effects on growth, protein efficiency ratio and feed utilization but resulted in a significant lipid accumulation in the body (Regost et al, 2001;Du et al, 2005;Kikuchi et al, 2009 …”

The present study was conducted to investigate the growth performance and feed utilization of marble goby,Oxyeleotris marmorata, juveniles fed with different levels of dietary lipid. Juvenile fish (initial mean weight 2.76 g) were fed with is onitrogenous diets including 10, 14, 18 and 22% of dietary lipid in triplicate groups for 15 weeks. The results showed that the highest growth performance and feed utilization was observed in fish fed D10. The increase of dietary lipid from 10 to 22 % did not improve growth, feed conversion rates, protein efficiency ratio, nitrogen retention efficiency, and apparent digestibility coefficients of protein and lipid (P>0.05). The increase of dietary lipid had significantly increased the whole body and hepatic lipid, hepato-somatic index, visceral-somatic index and intraperitoneal fat levels (P<0.05). These results suggest that there is no protein sparing effect of high dietary lipid levels in O. Marmorata due to possibly a limited ability to utilize dietary lipid. Based on the second-order polynomial regression analysis on protein efficiency ratio, ca. 12.1% of dietary lipid appears to be optimumfor growth from 2.76g to 13.76g body weight of O. marmorata juveniles.
