“…The maximum growth was observed at the 6% feeding rate, indicating the optimal utilization of feed nutrients by the sh for growth. These ndings align with the results reported by Ahmed (2007) for L. rohita and Khan (2004) for C. mrigala, where maximum growth and feed utilization were achieved at feeding rates of 6-8% and 4-6% of sh biomass, respectively. However, the study did not estimate the sh's maximum voluntary feed intake as the feeding rate was limited to a maximum of 6%.…”

The study investigated the effects of different feeding treatments on the growth, survival, and condition of co-reared Labeo gonius and L. rohita in a cemented tank system (size: 7.25 m X 1.85 m X 0.85 m each). Fish were housed at a density of 10 fish/ m2, maintaining a balanced 1:1 ratio between the two species. Pellet feed (PF) at daily rates of 2%, 4%, and 6% of fish biomass, and conventional feed (CF) consisting of rice bran and mustard oil cake at a daily rate of 2% were compared. The study spanned 60 days and monitored various parameters, including growth, survival, condition factor, hepatosomatic index (HSI), viscerosomatic index (VSI), and monthly water quality assessments. CF-fed fish had a specific growth rate of 0.96% per day, while PF-fed fish showed a range from 1% to 2.9% per day. Survival rates were 84.5% for CF-fed fish and 86.5-91.5% for PF-fed fish. The feed conversion ratio was 1.6 for CF and 1.4-1.45 for PF. PF-fed fish also had higher condition (b>3), HSI ranging from 0.93% to 1.87%, and VSI ranging from 4.1% to 7.6%. L. rohita exhibited better growth, while L. gonius showed higher survival in all tanks. In conclusion, PF is a more beneficial feeding option than CF for co-rearing L. gonius and L. rohita, particularly in hilly environments. It is recommended to administer PF at a rate equivalent to 6% of fish biomass for optimal results. These findings provide valuable guidance for simultaneously rearing L. rohita and L. gonius, facilitating the adoption of appropriate feeding strategies.

“…L abeo rohita (Rohu) is the most important fish species commonly cultured in Asia, particularly in the Indian subcontinent (Khan et al, 2004) because of its high growth rate, graceful body, market value, quality meat and consumer preference. The estimated production of this fish species in subcontinent was 9, 45,233 metric tons (FAO, 2014).…”

This study investigated the effects of dietary protein to energy (P/E) ratios on the nutrients and minerals digestibility of Labeo rohita fingerlings. Twelve experiment diets containing four protein levels (24, 26, 28, and 30 %) at three dietary energy levels (2400, 2700, and 3000 kcal/kg) with P/E ratios from 80.00 to 125.00 mg / kcal were evaluated. Each diet was randomly assigned to triplicate groups of seventeen fish averaging 6.5±0.6 g (mean±SD) for 10 wk. The chromic oxide in the diets was added as an additional inert marker to determine the digestibility of nutrients. The results from present study were demonstrated that the dietary P/E ratio significantly affects digestibility of protein, lipid and gross energy. In addition, the interactions of protein and energy significantly (p < 0.05) affected the digestibility of crude proteins, lipids, gross energy however, no significant (p > 0.05) effect was observed in digestibility of dry matter and ash. The increasing dietary P / E ratio significantly increased the digestibility of Na, Ca, P, Cu, Mn, Zn, and Fe. The diet with P / E ratio of 86.67 mg / kcal showed higher digestibility of dry matter (69.38±1.06), crude protein (88.18±1.59), lipid (93.43±0.22) and gross energy (86.50±0.57) while lower digestibility was observed in D12 (dietary protein 30% and dietary energy 3000 kcal/kg) with P/E ratio 100.00 mg / kcal. In conclusion, P/E ratio of 86.67 mg digestible protein / kcal digestible energy shows the maximum digestibility of nutrients and minerals in Labeo rohita fingerlings.
