“…This value corresponding to 2.73 g 100 g −1 of dietary protein is very close to the requirement reported for L. rohita 2.65 g 100 g −1 (1.0 g 100 g −1 cystine) of dietary protein (Khan & Jafri ), and higher than the requirement reported for channel catfish 2.34 g (Harding et al . ), milkfish 2.50 g (0.75 g 100 g −1 cystine) of dietary protein (Borlongon & Coloso ), sea bass 2.20 g (1.0 g 100 g −1 cystine) of dietary protein (Thebault, Alliot & Pastoureaud ), chinook salmon 1.50 g 100 g −1 (1.0 g 100 g −1 cystine) (Halver, DeLong & Mertz ) of dietary protein and lower than the requirement reported for Japanese eel 3.20 g (NRC ), yellow pearch 3.0 g (Twibell, Wilson & Brown ), African catfish 3.20 g 100 g −1 (Fagbenro, Balogun & Fasakin ) of dietary protein.…”

An 8 weeks feeding trial was conducted to determine the dietary methionine requirement of fingerling Indian catfish, Heteropneustes fossilis (6.08 ± 0.95 cm; 4.33 ± 0.52 g). Six isonitrogenous (40%) and isoenergetic (17.90 kJ g À1 GE) amino acid test diets were formulated with gradation of 0.25 g 100 g À1 containing graded levels of L -methionine (0.30, 0.55, 0.80, 1.05, 1.30 and 1.55 g 100 g À1 , dry diet) with 0.40 g 100 g À1 constant level of cystine. Twenty fish were stocked in triplicate groups, in 75-L circular trough with continuous flow-through system and fed experimental diets at 4% BW/day twice daily, at 08:00 and 18:00 hours. Maximum live weight gain (296%), best feed conversion ratio (1.56) and protein efficiency ratio (1.60) were occurred at 1.05 g 100 g À1 methionine, beyond which they showed declining tendency. However, quadratic regression analysis of weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and body protein deposition (BPD) data indicated requirement for methionine at 1.15, 1.08, 1.06 and 1.05 g 100 g À1 of dry diet respectively. Significantly (P < 0.05), higher whole body protein content, minimum moisture and intermediate fat contents were recorded at 1.05 g 100 g À1 dietary methionine level. Ash content remained insignificantly (P > 0.05) low among all the treatments, excepting at diet I and diet II. Body protein deposition was also found to be significantly (P < 0.05) higher at 1.05 g 100 g À1 methionine level. Best somatic and haematological indices values were also obtained at the requirement level. Based on above results, it is recommended that the diet for young H. fossilis should contain methionine at 1.09 g 100 g À1 dry diet, corresponding to 2.73 g 100 g À1 dietary protein with 0.40 g 100 g 1 cystine concentration for optimum growth and efficient feed utilization. Thus, the total sulphur amino acid requirement of H. fossilis would be (1.09 + 0.40) 1.49 g 100 g À1 of dry diet, corresponding to 3.73 g 100 g À1 of dietary protein.

A total of 630 juvenile Chinese sucker, with an average initial weight of 1.72 AE 0.05 g, were fed seven diets for 56 days to study the effect of dietary methionine levels on growth, feed utilization, body composition and haematological parameters on juvenile Chinese sucker. Diet 1 using fish meal as the sole protein source and diets 2-7 using fish meal and fermented soybean meal as intact protein sources supplemented with crystalline amino acids contained six levels of L-methionine ranging from 6.4 to 18.9 g kg À1 of dry diet at a constant dietary cystine level of 3.7 g kg À1 .Each diet was randomly assigned to three aquaria. Results indicated that the highest weight gain, specific growth rate (SGR), feed efficiency ratio, protein efficiency ratio and protein productive value occurred at 13.9 g methionine kg À1 diet among the methionine supplemented dietary groups, beyond which they showed declining tendency. The whole body and muscle protein contents of juvenile Chinese sucker were positively correlated with dietary methionine level, while muscle lipid content was negatively correlated with it. The total essential amino acids content of muscle was increased significantly with increasing dietary methionine level from 6.4 to 13.9 g kg À1 (P < 0.05). Apparent digestibility coefficients of dietary protein were significantly affected by dietary treatments. Serum protein, cholesterol and triacylglycerol increased with increasing dietary methionine levels, but showed a relatively lower value for fish fed the 18.9 g methionine kg À1 diet. Quadratic regression analysis of SGR against dietary methionine level indicated that optimal dietary methionine requirement for juvenile Chinese sucker was 14.1 g kg À1 of the diet in the presence of 3.7 g kg À1 cystine (corresponding to 32.0 g kg À1 of dietary protein on a dry-weight basis).

Dietary lysine (Fagbenro, Balogun, Fasakin & Bello‐Olusoji 1998), tryptophan (Fagbenro & Nwanna 1999), methionine (Fagbenro, Balogun & Fasakin 1999) and arginine (Fagbenro, Nwanna & Aebayo 1999) requirements of C. gariepinus have been established.

Dietary histidine requirement of fry African catfish, Clarias gariepinus (2.57 ± 0.02 cm; 0.22 ± 0.03 g) was quantified by feeding casein–gelatin‐based isonitrogenous (40% crude protein) and isocaloric (17.90 kJ g−1 gross energy) amino acid test diets with graded levels of histidine (0.25%, 0.30%, 0.35%, 0.40%, 0.45% and 0.50% dry diet) in eighteen 80 L indoor circular aqua‐coloured troughs provided with the flow‐through system for 12 weeks. Maximum absolute weight gain (2.66), best feed conversion ratio (1.29), highest protein efficiency ratio (1.94), protein retention efficiency (34%) and energy retention efficiency (70.4%) were achieved at 0.40% dietary histidine. Broken‐line and non‐linear regression models were adopted to assess dietary histidine requirement for C. gariepinus. When analysed using broken‐line regression model these parameters were also best at 0.40% dietary histidine corresponding to 1.0% protein, respectively, whereas using second‐degree polynomial regression analysis, histidine requirement was obtained at 0.42%, 0.41%, 0.40%, 0.41% and 0.41% of dry diet, corresponding to 1.05%, 1.02%, 1.0%, 1.02% and 1.02% protein respectively. Based on the broken‐line and second‐degree polynomial regression analyses of the growth and nutrient retention data, optimum histidine requirement of fry C. gariepinus was found to be in the range of 0.40–0.42% dry diet, corresponding to 1.0–1.05% of dietary protein.
