“…Therefore, based on our results, feeding fish at 7% BW day -1 is a waste as it is unable to produce quality fish because the aim of the feed is to produce more gain in protein than that in fat. At food intake levels higher than the optimum, growth increase is negligible (Tsevis et al 1992). Moreover, a ration in excess may also lead to a poor FCR and decreased DE, which has a detrimental effect on water quality (Johnston et al 2003).…”

The effects of ration levels on growth, conversion efficiencies and body composition of fingerling Heteropneustes fossilis (6.8 ± 0.04 cm, 5.0 ± 0.02 g) were studied by feeding isonitrogenous (40% crude protein) and isocaloric (19.06 MJ kg -1 gross energy) diets representing 1, 3, 5, 7 and 9% of the body weight (BW) day -1 to triplicate groups of fish . Growth performance of the fish fed at the various ration levels was evaluated on the basis of live weight gain percentage (LWG%), feed conversion ratio (FCR), specific growth rate percentage (SGR%), protein retention efficiency (PRE%) and energy retention efficiency (ERE%) data. Maximum LWG% and SGR were obtained at a feeding rate of 7% BW day -1 , whereas best FCR (1.6), PRE% and ERE% were recorded at a feeding rate of 5% BW day -1 . Maximum body protein was also obtained for the group receiving the diet representing 5% of their body weight. However, a linear increase in fat content was noted with the increase in ration levels up to 7% BW day -1 . The SGR, FCR, PRE and ERE data were also analyzed using second-degree polynomial regression analysis to obtain more precise information on ration level, with the results showing that the optimal ration for these parameters was 6.8, 6.1, 5.9 and 6.2% BW day -1 , respectively. Based on the above second-degree polynomial regression analysis, the optimum ration level for better growth, conversion efficiencies and body composition of fingerling H. fossilis was found to be in the range of 5.9-6.8% of the BW day -1 , corresponding to 2.36-2.72 g protein and 88.20-101.66 MJ digestible energy kg -1 diet day -1 .

“…A suitable feeding regime with optimal feeding frequency and temperature not only enhances growth and feeding efficiency of fish, but also minimizes size variations, feed waste, production cost, and disease occurrence [34][35][36][37]. Water temperature and feeding frequency are two important components affecting growth, which have been studied in several fish species such as Channel catfish [38], European seabass [39], rainbow trout [40,41], Tiger Puffer [42], tilapia [24], pikeperch [43], and Asian seabass [44]. Temperature affects food consumption, digestion rate, and growth rate through variations in metabolism [15,45], use of nutrients and energy [18,46], and digestive enzyme activities [17,[47][48][49].…”

“…Fish feeding is one of the most important factors in commercial fish farming because feeding regime may have consequences on both growth performance and feed wastage (Tsevis et al 1992;Azzaydi et al 2000). During the last decade, there has been a marked increase in the use of extruded pellet (EP) for feeding fish.…”

A feeding trial was conducted to evaluate the effects of two different sizes of extruded pellets (EP) (EP 1 -3 mm or EP 2 -5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared in semi-recirculation system. A total of 450 fish with an average initial weight of 5.0 ± 0.2 g (mean ± SD) were fed one of the three experimental diets in triplicate groups. At the end of a 6-week feeding trial, weight gain, specific growth rate, and feed efficiency of fish fed EP diets were significantly higher than those of fish fed MP (P < 0.05). Water quality parameters like turbidity, total ammonia nitrogen, and total phosphorous from tanks of fish fed EP 1 and EP 2 were significantly lower than those from tanks of fish fed MP. Blood plasma glutamic oxaloacetic transaminase and glucose concentration were significantly higher in fish fed MP diet compared to fish fed EP diets (P < 0.05). Whole body crude protein contents in fish fed EP diets were higher than those from the fish fed MP diet. Whole body amino acid content like threonine, aspartic acid, serine, tyrosine, and cystine were found to be significantly higher in fish fed EP diets than those in fish fed MP diet. In considering overall performance of olive flounder, EP 2 diet could be recommended for the successful aquaculture of this important fish species.
