“…Tis is the frst research to indicate the optimal DCP requirement for H. jerdoni juveniles. Previously, various authors documented the optimum protein requirement of various barb species, such as 500 g protein/kg for tinfoil barb fry [22], 300-350 g protein/kg for lemon fn barb hybrid fngerlings [22], 350 g protein/kg for Puntius vittatus [23], 300 g protein/kg for Puntius gonionotus [24], 297 g protein/ kg for Labeo bata fry [25], 281.48-282.53 g protein/kg for Cirrhinus reba fry [26], 250 g protein/kg for Osteobrama belangeri fngerlings [27], 290 g protein/kg goldfsh fry [28], and 318.0-327.6 g protein/kg for Hypselobarbus pulchellus fngerlings [29].…”

“…Terefore, dietary protein optimisation of a species at various life stages is critical towards making aquaculture lucrative and sustainable. Accordingly, various authors documented the optimum protein requirement of various barb species, such as 500 g protein/kg for tinfoil barb fry [22], 300-350 g protein/kg for lemon fn barb hybrid fngerlings [22], 350 g protein/kg for Puntius vittatus [23], 300 g protein/kg for Puntius gonionotus [24], 297 g protein/kg for Labeo bata fry [25], 281.48-282.53 g protein/kg for Cirrhinus reba fry [26], 250 g protein/kg for Osteobrama belangeri fngerlings [27], 290 g protein/kg goldfsh fry [28], and 318.0-327.6 g protein/kg for Hypselobarbus pulchellus fngerlings [29]. In this regard, the present research explores the dietary protein requirement of Jerdon's carp (H. jerdoni) since it is a relatively new commercial ornamental fsh, and many aspects of its culture including its food and feeding habit as well as nutritional requirements have not been examined yet.…”

A 60-day feeding trial has been carried out to access the optimal dietary crude protein (DCP) requirement of juvenile Jerdon’s carp, Hypselobarbus jerdoni. Six isoenergetic (around 400 Kcal DE/100 g), isolipidic (60.80 g/kg), and heteronitrogenous diets were prepared with graded levels of protein, viz., 200, 250, 300, 350, 400, and 450 g/kg (TCP 20-TCP 45 with 50 g/kg incremental level). A completely randomised design (CRD) was used to distribute 270 Jerdon’s carp juveniles (6.12–6.18 g) in six experimental groups in triplicates (15 fish/tank, 200 l water capacity). After 60 days, the fishes of the TCP30 group showed significantly higher weight gain, final body weight, and percentage weight gain (WG%). The fish of the TCP30 group exhibited a significantly higher feed efficiency ratio and specific growth rate. On the other hand, a significantly lower feed conversion ratio is recorded in the TCP30 and TCP35 groups. The protein efficiency ratio of fish was reduced significantly with the elevated DCP level. Whole-body moisture, lipid, and total ash contents of H. jerdoni were remain unaffected by DCP levels. However, DCP levels significantly influenced the whole-body protein of H. jerdoni juveniles, with significantly higher values noticed in the TCP30 and TCP35 groups. The TCP35, TCP40, and TCP45 groups exhibited significantly higher (p<0.05) protease activity, and the amylase activity showed a decreasing trend in response to dietary protein levels. A significantly (p<0.05) higher SOD and CAT activity were observed in the TCP20 and TCP25 groups. However, lower hepatic glutamate pyruvate transaminase and glutamic-oxaloacetic transaminase activity were observed in the TCP30 and TCP35 groups, respectively. Furthermore, based on broken-line linear and second-order polynomial regression with respect to WG%, the optimal dietary crude protein requirement of H. jerdoni cultured for 60 days was found to be 309.72 and 316.40 g/kg.

“…Since captive breeding of O. bimaculatus has been established (Raizada et al 2013), it is necessary to develop larval diets to ensure growth and survivability of the species during the stages of early development, which is essential for reliable and regular supply of the fish for widespread commercial production. A previous study conducted on O. bimaculatus larvae determined a required level of 40% crude protein in the diets for this species (Paul et al 2020).…”

The Indian butter catfish, Ompok bimaculatus (Bloch, 1794), is a high-value catfish that has gained immense consumer preference in South-East Asia. However, information on the nutritional requirements of this species is scanty. Hence, an experiment was conducted to evaluate the effects of varying dietary lipid levels on growth, body composition, and activities of digestive and metabolic enzymes in larvae. Three isonitrogenous (40% crude protein) diets were formulated by supplementing fish and vegetable oil (1:1) at 4.5% (D1), 7% (D2), and 9.5% (D3) levels (containing crude lipid 5.7%, 8.0%, and 10.45%, respectively in diets D1–D3) to a fish meal- and oilcake-based formulated diet. Experimental diets were fed to butter catfish larvae (0.15 ± 0.01 g) in triplicate groups for a period of 42 days. Proximate compositions of the experimental diets, as well as fish carcass, were analyzed using standard procedures (AOAC 2005). Digestive and metabolic enzyme activities were analyzed at the completion of the experiment by standard methodology. Butter catfish larvae fed the diet D2 (8% crude lipid) resulted in the best performance in terms of weight gain (final weight 1.40 ± 0.07 g), net weight gain (1.31 ± 0.06 g), specific growth rate (5.50 ± 0.05% · day−1), and protein efficiency ratio (2.39 ± 0.17). The highest lipid deposition (2.90 ± 0.12%) in the carcass was also recorded in fish reared on diet D2. The final weight, net weight gain, protein efficiency ratio, and specific growth rate were significantly (P < 0.05) higher in D2 having 8% lipid. Moisture and lipid contents of the whole body were significantly (P < 0.05) higher in larvae fed diet D2. Amylase activity in fish significantly (P < 0.05) decreased with increasing dietary lipid levels. The maximum alkaline protease, pepsin, and lipase activities were noticed in the larvae fed diet D2. Progressive decrease in liver glucose-6-phosphate dehydrogenase activities and significant increase (P < 0.05) in the activities of neoglucogenic enzymes (glucose-6-phosphatase and fructose-1,6-bis phosphatase) were noticed with an increase in dietary lipid levels. Significantly lower (P < 0.05) activities of LDH, ALT, and AST were recorded in the group fed diet D2. Results of the study indicated that 8% crude lipid in the diet could assure optimum growth and survival of butter catfish larvae during early development. An appraisal on growth, body composition, and digestive as well as metabolic function in the butter catfish larvae recorded in the study might provide some important information to consider application of formulated diets for the larviculture of Ompok bimaculatus.
