“…In the present study, increasing dietary lipid to 17.6% or higher (20.0%, 22.6%) resulted in increased wholebody lipid. Similar results have been reported in rainbow trout [18], red drum [33,40], striped bass [41], channel catfish [42,43], hybrid Clarias catfish [29] walking catfish [8], Tilupia zillii [43], common carp [44,45] and brown-marbled grouper [46].…”

An 8-week growth trial was undertaken to determine effects of different dietary carbohydrate (CHO)/lipid (L) ratios on growth, feed utilization and body composition of early giant grouper Epinephelus lanceolatus juveniles. Five isoenergetic (4.1 kcal/g) and isonitrogenous (50% CP, dry-matter basis) experimental diets were formulated to contain different crude lipid (CL) levels (22%, 19.8%, 17.6%, 15.4% or 13.2%, dry-matter basis) and together different corn starch levels (0%, 4.95%, 9.9%, 14.85% or 19.8%), thereby forming different dietary CHO/L ratios. Groups of 41 early giant grouper juveniles (average initial weight of 0.397 g/fish) were stocked into small floating cages (L 120 cm × W 70 cm × H 50 cm). Triplicate groups of fish were fed each dietary treatment three times daily to apparent satiation.

“…Literature review shows that dietary protein and lipid requirements of groupers are in the range of 40-55% and 8-16%, respectively (Chen and Tsai, 1994;Luo et al, 2004;Shapawi et al, 2014;Shiau and Lan, 1996;Teng and Chua, 1978;Tuan and Williams, 2007;Usman et al, 2005;Williams et al, 2004). In the present study growth performance of fish was improved by increment of dietary protein level from 40 to 50%, but further increase of dietary protein to 55% led to a decreased growth performance.…”

“…However, protein sparing effect was reported in rockfish juvenile Sebates schlegeli by (Lee et al, 2002) who recorded significantly better protein utilization, weight gain, feed efficiency, ADC of protein and lipid in fish fed with 42% protein and 14% lipid compared to those fed with 49% protein and 7% lipid. Similar (Vergara et al, 1999), haddock Melanogrammus aeglefinus (Tibbetts et al, 2005) and brown-marbled grouper Epinephelus fuscoguttatus (Shapawi et al, 2014). The absence of protein sparing effect in the present study may be due to employment of a sufficient amount of dietary protein (50%) for O. marmorata.…”

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.
