“…These haematological indices are also used to assess the functional activities of the oxygen carrying capacity of the bloodstream and have been widely used as an indicator of metal pollution in the aquatic environment (Shah and Altindag 2005;Maheswaran et al 2008). Besides these, they are also useful for determining the health status of the fish in response to dietary supplements (Klinger et al 1996;Congleton and Wagner 2006;Mohammed and Sambo 2007). In the present study, the haemoglobin (Hb) and haematocrit (HT%) values were also affected by increasing tryptophan concentrations and were found to be significantly higher at the requirement level 0.34 g 100 g -1 followed by those fed at 0.44 g 100 g -1 tryptophan containing diet.…”

“…The haematological parameters now-a-days have been proved to be essential tools for analysing the health status and biological manifestations of fish in determining the nutritional status of the fish in response to dietary manipulation (Adhikari et al 2004;Shah and Altindag 2005;Congleton and Wagner 2006;Mohammed and Sambo 2007;Maheswaran et al 2008). Therefore, in the present study, haematological parameters have also been analysed in addition to the growth parameters for assessing the effects of dietary tryptophan on growth performance of H. fossilis.…”

An 8-week feeding trial was conducted to determine the dietary tryptophan requirement of fingerling Indian catfish, Heteropneustes fossilis (6.10 ± 1.15 cm, 4.44 ± 0.50 g). Six isonitrogenous (40 g 100 g⁻¹) and isoenergetic (17.90 kJ g⁻¹) amino acid test diets were formulated with gradation of 0.1 g 100 g⁻¹ containing graded levels of L-tryptophan (0.04-0.54 g 100 g⁻¹, dry diet). Fish were stocked in triplicate groups, in 75-L circular trough with flow-through system and fed experimental diets at 4% BW/day twice daily. Maximum live weight gain (258%), best feed conversion ratio (FCR) (1.54) and protein efficiency ratio (PER) (1.62) were obtained in fish fed diet containing 0.34 g 100 g⁻¹ tryptophan. However, quadratic regression analysis of weight gain, FCR, PER and body protein deposition (BPD) data indicated requirements for dietary tryptophan at 0.37, 0.33, 0.32 and 0.33 g 100 g⁻¹ of dry diet, respectively. Significantly (P < 0.05) higher body protein, minimum moisture and intermediate fat contents were recorded at 0.34 g 100 g⁻¹ dietary tryptophan diet. Ash content was not significantly different (P > 0.05) among treatments except for diets 0.04 and 0.14 g 100 g⁻¹. Excellent somatic and haematological indices values were obtained at the requirement level. Based on above results, it is recommended that the diet for H. fossilis should contain tryptophan at 0.32 g 100 g⁻¹, dry diet, corresponding to 0.80 g 100 g⁻¹ dietary protein for optimum growth and efficient feed utilization.

“…). Besides these they are also useful for biological manifestation of the fish used for determining the health status of the fish in response to dietary supplements (Klinger, Blazer & Echevarria ; Congleton & Wagner ; Mohammed & Sambo ). In this study, the haemoglobulin (Hb) and haematocrit (HT%) values were also affected by increasing methionine concentration with constant level of cystine and were found to be significantly higher at the requirement level 1.05 g 100 g −1 , followed by those fed at 1.30 g 100 g −1 methionine containing diet.…”

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.

“…Histidine constitutes 10% amino acid composition of haemoglobin (Tristram & Smith ). Since haematological parameters were found to be sensitive to dietary manipulations (Mohammed & Sambo ), the changes in these parameters including haemoglobin, RBCs and haematocrit were also utilized to estimate the histidine requirement of this fish.…”

To investigate the histidine requirement of fingerling Catla catla (3.65 AE 0.15 cm; 0.65 AE 0.36 g), six casein-gelatin based diets (33% CP; 13.58 kJ g À1 DE) containing graded levels of L-histidine (0.25%, 0.39%, 0.53%, 0.67%, 0.83%, 0.96% of the dry diet) were fed near to satiation thrice a day for 12 weeks. Maximum absolute weight gain (AWG; 8.63 g fish À1 ), protein gain (PG; 1.45 g fish À1 ), histidine gain (HG, 48.19 mg fish À1 ), RNA/DNA ratio (4.15), best feed conversion ratio (FCR;1.31), highest haemoglobin (Hb, 9.61 g dL À1 ), RBCs (2.84 9 10 6 mm À3 ) and haematocrit (Ht, 30.12%) were recorded in fish fed diet containing 0.67% histidine. However, brokenline regression analysis of AWG, PG, HG, RNA/ DNA ratio, FCR, Hb, Ht and RBCs against dietary histidine reflected the histidine requirement at 0.65%, 0.64%, 0.63%, 0.68%, 0.63%, 0.66%, 0.68% and 0.65% dry diet respectively. Carcass protein was found to improve significantly (P < 0.05) from 13.36% to 16.42% with the increase in dietary histidine from 0.25% to 0.67%. Based on regression analysis of AWG, PG, HG, RNA/DNA ratio, FCR, Hb, Ht and RBCs, it is recommended that the diet for fingerling catla should contain histidine in the range of 0.63-0.68% dry diet, equivalent to 1.91-2.06% of the dietary protein for optimum growth, feed utilization, blood profile and carcass composition.
