“…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.

“…Higher protease activity in the treated fish can be correlated with higher carcass protein.

Low fishmeal diets (10%) with varied levels of maize (40-31%) and sardine oil (0-9%) were fed for 120 days to triplicate groups of catla (Catla catla Hamilton,1822) fingerlings (average weight 1.84-1.90 g) stocked @ 1 fish per m 2 in cement tanks with soil base fertilised with poultry manure. Fish fed on diet containing 6% oil and 34% maize (T 2 ) showed the highest (p<0.05) growth, followed by those received 9/31 (T 3 ), 3/37 (T 1 ) and 0/40% (T 0 ) oil/maize supplemented diets. Food conversion ratio improved due to oil supplementation, while protein efficiency ratio was not affected significantly. Dietary lipid had a positive impact on carcass protein and lipid levels (p<0.05). Fish survival ranged from 90.73% in all the treatment groups to 92.58% in the control, without any significant (p>0.05) difference among them. Net fish production on termination of the experiment was lowest (820 g) in the control and the highest (1017.85 g) inT 2 treatment. Viscerosomatic index (VSI) varied from 3.59 (T 2 ) to 4.65% (T 0 ) and hepatosomatic index (HSI) from 1.13 (T 0 ) to 1.91% (T 3 ). RNA/DNA ratio was highest (3.05) in T 2 and lowest (1.84) in T 0 . An increase in intestinal amylase activity was observed in the treated fish, while intestinal protease and lipase activity showed increase only with higher levels of oil supplementation (6 and 9%). No difference (p>0.05) in enzyme activity was observed in the hepatopancreas of the control and treated fish. The results indicated beneficial effects of incorporating maize and fish oil in low fishmeal diet for catla.

“…Regarding sparids, the optimum dietary lipid levels were recommended to be ca. 22% in S. aurata [91], ca. 15% in P. major [28], 15% in P. pagrus [31], 17% in D. dentex [18] and 18% in D. sargus [92].…”

Silvery-black porgy (Sparidentex hasta) is recognized as one of the most promising fish species for aquaculture diversification in the Persian Gulf and the Oman Sea regions. In this regard, S. hasta has received considerable attention, and nutritional studies focused on establishing the nutritional requirements for improving diet formulation have been conducted during recent years. Considering the results from different dose-response nutritional studies on macronutrient requirements conducted in this species, it can be concluded that diets containing ca. 48% crude protein, 15% crude lipid, 15% carbohydrates and 20 KJ g −1 gross energy are recommended for on-growing S. hasta juveniles. In addition, the optimum essential amino acid profile for this species (expressed as g 16 g N −1 ), should be approximately arginine 5.3, lysine 6.0, threonine 5.2, histidine 2.5, isoleucine 4.6, leucine 5.4, methionine + cysteine 4.0 (in a diet containing 0.6 cysteine), phenylalanine + tyrosine 5.6 (in a diet containing 1.9 tyrosine), tryptophan 1.0 and valine 4.6. Moreover, the optimum dietary n-3 long chain polyunsaturated fatty acids and soybean lecithin are recommended to be 0.8% and 6%, respectively. The maximum replacement of fish meal with soy protein is recommended to be between 16.5% and 27.3%. In addition, different vegetal oil sources are also recommended for partial and almost complete replacement of fish oil in diets. Although the nutritional requirements in terms of macronutrients have been established under laboratory conditions, the analysis of the available literature indicate that future studies need to be conducted using a more holistic approach under intensive farming conditions in which different nutrients or additives need to be tested under different rearing conditions for refining nutrient requirements in this species.
