“…In Wuchang bream (Megalobrama amblycephala), the weight gain (WG) and muscle protein content were significantly increased, while the feed conversion ratio (FCR) and muscle lipid content were significantly reduced as dietary protein level increased from 30% to 34% [2]. However, high dietary protein level increased the feed costs [3] and ammonia emissions [4]. Güroy et al [4] found that increasing dietary protein level from 35% to 50% significantly increased the ammonia emissions in yellow tail cichlid (Pseudotropheus acei).…”

This study investigated the dietary effects of lipid and protein levels on growth performance, feed utilization, body composition, lipid metabolism, and antioxidant capacity of triploid rainbow trout, Oncorhynchus mykiss. A 3 × 2 two-factor design was conducted with three crude lipid levels of 4%, 9%, and 14% (L4, L9, and L14) and two crude protein levels of 44%, 49% (P44, P49). Therefore, a total of six diets were prepared as P44/L4, P44/L9, P44/L14, P49/L4, P49/L9, and P49/L14. Triploid rainbow trout (initial body weight 65.0 ± 0.1 g) were fed one of the six diets for 80 days. The results showed that weight gain (WG), protein retention (PR), and protein efficiency rate (PER) significantly increased with increasing the dietary lipid level at the same crude protein level, while feed conversion ratio (FCR) and hepatosomatic index significantly decreased ( P < 0.05 ). At the same lipid level, there was no difference in WG, FCR, PR, PER between 44% and 49% crude protein group ( P > 0.05 ). The P49/L14 group had the highest WG (374.6%) and lowest FCR (1.25), while P44/L14 group had the highest PER (1.80) and PR (25.06%) with similar WG and FCR to P49/L14 group. The crude lipid contents in whole fish were significantly higher in the L14 group than those in the L4 and L9 groups ( P < 0.05 ). Muscle n-3 PUFAs, n-6 PUFAs, and PUFAs levels were positively correlated with dietary lipid level, while n-6 PUFAs was negatively correlated with dietary protein level. Dietary protein, dietary lipid, and their interaction significantly affected hepatic malondialdehyde (MDA) content, aspartate aminotransferase, lipase (LPS), and fatty acid synthase (FAS) activities ( P < 0.05 ). In both P44 and P49 groups, LPS and FAS activities increased with increasing the dietary lipid level. MDA content significantly decreased in the P44 group and increased in the P49 group with increasing the dietary lipid level ( P < 0.05 ). As dietary protein level increased, serum total cholesterol level increased, while hepatic phosphoenolpyruvate carboxykinase activity decreased. With increasing the dietary lipid level, total superoxide dismutase, catalase, total nitric oxide synthase, and fructose-1,6-bisphosphatase activities showed an increasing trend, while the opposite was true for alanine aminotransferase activity. In conclusion, based on growth performance and feed utilization, dietary protein level of 44% and dietary lipid level of 14% (measured value, 43.71% and 13.62%) were suggested for young triploid rainbow trout.

“…So far many of the ornamental fish traders have been using shrimp feeds or other fish feeds meant for rearing the food fishes. Therefore, development of species specific ornamental fish diet as per the nutrient requirement of fish is one of the priority areas in fish nutrition research [31,32]. Among freshwater ornamental fish, blue gourami, Trichogaster trichopterus is an important sought after ornamental fish.…”

Based on the nutrient requirement of blue gourami, Trichogaster trichopterus fingerlings as reported earlier, nine experimental diets with 350 g protein, 80-100 g lipid and 16-17 MJ digestible energy/kg diet were formulated using snail meat (D-1), freshwater fish processing waste (D-2), surimi by-product (D-3), chicken offal (D-4), earthworm (D-5), squid (D-6), mussel (T-7), chicken liver (T-8) and lean prawn (T-9) as major protein source in addition to fish meal and peanut oil cake and fed ad libitum to the fish (3.54 ± 0.02 g) for a period of 45 days. Twenty seven indoor circular fiber-reinforced plastic tanks with 200 L of water were used for rearing the fish. At the end of the experiment it was found that the fish fed squid meal Diet (D-6) had the best results in terms of weight gain, food conversion ratio (FCR), specific growth rate (SGR) and protein efficiency ratio (PER). However, the freshwater fish processing waste (D-2) and surimi by-product (D-3) diets had almost similar (p>0.05) growth and dietary performance as that of squid, mussel, chicken liver and lean prawn meal diets and therefore, both these fish processing waste and surimi by-product could be used as non-conventional protein sources in formulating the nutritionally balanced cost-effective diets for blue gourami.

“…Therefore, it should be carefully formulated to meet the nutrient requirements (Sui et al, 2015). Other advantages associated with an optimized dietary protein level include rapid and cost-effective growth, reduced environmental impact, and improved water quality (Guroy et al, 2012). Fishmeal is the most common and expensive protein source used in aqua feed formulations.…”

The present study was carried out to evaluate the effect of varying levels of protein on growth performance, body indices, proximate and fatty acid composition of white leg shrimp (Litopenaeus vannamei) juveniles with an average weight of (1.97±0.09) g. Experimental diets containing 30, 35 and 40% protein were prepared and the feeding experiment was carried out for the duration of 45 days. The results of the feeding trial showed that final body weight (FBW), weight gain (WG), daily growth co-efficient (DGC) and feed conversion ratio (FCR) increased (p<0.05) significantly in the shrimp fed with diet containing 35% protein. Similarly, better survival was observed in all the treatments. The body indices total weight, edible, non-edible portion, hepato somatic index and muscle ratio was significantly (p<0.05) higher in shrimp fed with diet containing 35% protein. Whole body composition of post fed animals showed non-significant differences (p>0.05) among the various treatments. The fatty acid composition of whole, edible and non-edible portions showed that 17:0 (Heptadecanoic acid), 18:0 (Octadecanoic acid), 20:4n-6 (Eicosanoic acid) 21:0 (Heneicosanoic acid), 24:0 (Tetracosanoic acid) was higher in edible portion of shrimp fed with 35% protein supplemented diet. Similarly, other fatty acid was higher in whole body and non-edible portions. The results of this experiment infer that 35% protein has got a beneficial effect in the diet of L. vannamei juveniles for improving the various growth parameters.
