“…This is similar to values obtained for various cultured freshwater and marine fish including Nile tilapia, O. niloticus , 26.9 mg protein/kJ (El‐Sayed and Teshima 1992); American eel, Anguilla rostrata , 22 mg protein/kJ (Tibbetts et al 2000); and black catfish, 23.6 mg protein/kJ (Salhi et al 2004). However, the result is lower than the values obtained for African catfish, Clarias gariepinus , 34.7 mg protein/kJ (Henken et al 1986); hybrid striped bass, Morone chrysops × Morone saxatilis , 29.9 mg protein/kJ (Nematipour et al 1992); Asian seabass, Lates calcarifer , 30.6 mg protein/kJ (Catacutan and Coloso 1995); and olive flounder, Paralichthys olivaceus , 27.5 mg protein/kJ (Kim et al 2004), and higher than those obtained for snakehead, Channa striata , 21.7 mg protein/kJ (Samantaray and Mohanty 1997) and European seabass, Dicentrarchus labrax , 21 mg protein/kJ (Peres and Oliva‐Teles 1999). The differences in results obtained in different studies could be attributed to factors such as fish size and species, feed composition and preparation method, feeding habit, experimental design, rearing method, as well as water temperature and salinity (Tuncer et al 1990; Takeuchi et al 1992; Keembiyehetty and Wilson 1998).…”

A 2 × 3 factorial design was used to reevaluate the dietary protein requirements and to determine the optimum dietary protein to energy (P/E) ratios in Japanese eel, Anguilla japonica, reared in the recirculating system. For each of two experiments, six experimental diets (45P16, 45P17, 45P19, 50P16, 50P17, and 50P19) were formulated and prepared to contain two protein levels (45 and 50%) and three energy levels (16, 17, and 19 kJ/g diet) at each protein level. In the first experiment, glass eel of initial weight 0.1 ± 0.02 g (mean ± SD) were used, while the second experiment was conducted with juvenile eel of initial weight 15.0 ± 3 g (mean ± SD). The first and second experimental periods were 6 and 16 wk for the glass and juvenile eel, respectively. At the end of the first experiment, there were no protein, energy, and their interaction effects. Also, there were no significant differences in weight gain (WG), specific growth rate (SGR), feed efficiency (FE), and protein efficiency ratio (PER) for glass Japanese eel fed all diets. Although there were no significant differences in growth parameters of glass eel fed all experimental diets, these parameters were higher for fish fed 50P16 than for fish fed the other diets. For the second experiment, there were significant protein effects on WG, SGR, and PER (P < 0.05). However, there were neither significant energy effects nor protein and energy interaction effects on WG, SGR, FE, and PER. Fish fed 45P19 had a higher WG, SGR, and PER than did fish fed 45P16, 50P16, and 50P19 (P < 0.05). However, there were no significant differences in growth parameters among fish fed 45P16, 45P17, 50P16, 50P17, and 50P19 and among those fed 45P17, 45P19, and 50P17. These results may indicate that the optimum dietary protein requirement and the P/E ratio could be 44.3% and 24.1 mg protein/kJ (45P19), respectively, in juvenile Japanese eel, based on WG, SGR, and PER.

“…Highest crude protein and crude lipid level was observed in T1 group fed with probiotics Bactocell. Body lipid and body moisture were inversely related while body ash contents remained almost constant as reported in previous experiments with African catfish, Clarias gariepinus (Machiels and Henken, 1985;Henken et al, 1986). In the study, fish fed diets containing probiotics supplement showed higher body protein and lipid content than the control diet.…”

“…Increase in dietary lipid leads to increased growth and protein efficiency ratio (Lovell 1989). According to Henken, Machiels, Dekker and Hogendoom (1986), for example, the optimum P/E ratio for African catfish was 25.4 mg protein kJ À1 at 24°C and 34.7 mg protein kJ À1 at 29°C, indicating a variation in optimum P/E level with temperature. Hung, Storebakken, Cui, Tian and Einen (1997) showed that diets containing high levels of energy (250-350 g per kg lipid) can improve the growth rate and food efficiency in white sturgeon, Acipencer transmontanus, and this is in agreement with results obtained in the current study.…”

A 3 9 4 factorial design was used to evaluate the dietary protein requirement and to determine the optimum dietary protein to energy (P/DE) ratio in sub-yearling Persian sturgeon, Acipenser persicus, reared in the indoor system. and 50 P 19 ) were formulated and prepared to contain three protein levels (40%, 45% and 50%) and four digestible energy levels (16, 17, 18 and 19 kJ g À1 diet) at each protein level. Fish averaging 103.3 ± 3.5 (mean ± SD) were fed one of the experimental diets for 14 weeks. At the end of the experimental period, there were significant energy effects (P < 0.05) on weight gain (WG) and specific growth rate (SGR). Weight gain and SGR tended to decrease, although non-significantly, with increase in dietary protein levels. Furthermore, there were significant protein and energy interaction effects on WG, SGR, hepatosomatic index and protein efficiency ratio. However, there were no significant dietary protein, energy or their interaction effects on feed efficiency for fish fed all diets. Weight gain and SGR of fish fed 40 P 19 were significantly higher than those of fish fed 40 P 16 , 45 P 16 , 45 P 17 , 50 P 16 and 50 P 17 diets (P < 0.05). There were no significant differences in WG and SGR among fish fed 40 P 17 , 40 P 18 , 40 P 19 , 45 P 18 , 45 P 19 , 50 P 18 and 50 P 19 diets. These results may indicate that the optimum dietary protein requirement and the P/DE ratio could be 40% protein and 22.0 mg protein kJ À1 ( 40 P 18 ), respectively, in Persian sturgeon, based on growth performance and feed utilization.
