“…The PER of P. hypophthalmus in the present study increased linearly up to T3 (Dietary Energy level, ) and then again start decreasing when the energy content in the diet further increased. Similar results were supported by Lee et al (2002);Steffens (1981) and De Silva et al (1991) who find that an increase in dietary energy content of feed resulted in higher protein efficiency ratios which indicate a lower use of protein as an energy source when non-protein energy was increased in the diet. Temperature also has marked effect on PER of fish.…”

A 60-days feeding trial was conducted to study the dietary energy requirement of Pangasianodon hypophthalmus (Sauvage1878) juveniles reared either at ambient (24.5°C) or higher temperature (32°C) and fed with one of the four diets having dietary energy content of 342 Kcal. 100 g -1 (T1), 379 Kcal. 100 g -1 (T2), 428.5 Kcal. 100 g -1 (T3) and 448.6 Kcal. 100 g -1 (T4). Juveniles of P. hypophthalmus with amean weight 4.27±0.12 to 4.40±0.10 g was stocked in 24 uniform size plastic rectangular tanks in triplicates with 10 fish per tank following a 2x4 factorial design. Growth performance and nutrient utilization of P. hypophthalmus were higher at the dietary energy content of 428.5 Kcal. 100 g -1 (T3) at both the temperatures. The body composition of P. hypophthalmus did not differ significantly (P>0.05) as the energy content of the diet increase. However, the tissue lipid content was significantly varied (P<0.05) at different temperature and energy levels. Based on the second order polynomial regression equation the dietary energy requirement of P. hypophthalmus was recorded to be 410 Kcal. 100 g -1 and 402.5 Kcal. 100 g -1 at 32°C and at ambient temperature(24.5°C), respectively.

“…In fact, except during reproduction, the hepatosomatic index is considered in fish as a good indicator of both food consumption and energy stock. A decrease of this index indicates insufficient nutritional conditions according to energy needs (Parent et al 1985, Miglavs & Jobling 1989, De Silva et al 1991.…”

“…Additionally, it is possible that other nutrients could have affected the growth of these fish or produced interactive effects with various dietary components 32 ; much remains unknown about how specific nutrients affect the rare minnow. The composition of our semi-purified diets was relatively simple and might lack some factors that would be found in natural foods and could promote digestion and nutrient absorption 33 .…”
