“…In those in vestigations basically fishmeal, rice bran, and mustard oil cake were used to formulate the diets. Csengeri and Petitjean (1987) reported a survival rate of 80% in cyprinid larvae using a liver based diet whereas, more than 80% survival rates were achieved in the present study even in the control groups.…”

A 21-day feeding experiment was conducted to assess the effects of diets supplemented with fish intestinal bacteria producing extracellular enzyme on growth and survival of rohu, Labeo rohita (Hamilton) spawn (average weight 0.3 mg). Intestinal bacteria were isolated from healthy rohu fingerlings s averag � w � ight 3.51 _ ±0.31 _ g). Six isocaloric (4.24 kcal·g-) and 1somtrogenous \approximately 35% crude protein) diets (Dl-D6) were prepared containing 32% fish meal, 34% mustard oil cake, 30% rice bran, 2o/o cod liver oil, and 2% vitamin premix. Experimental diets (D2-D6) were supplemented with the isolated bacterial strain Bacillus circu lans Lr 1

“…The benefits are believed to arise from a correct balance of vitamins plus an acceptability factor (Hastings and Dickie 1972). Finely divided liver has also been used as a suitable food for larval finfish (Csengeri and Petitjean 1987). The present study and that of Heinen and Mensi (1991) indicate that beef liver can serve as a useful feed supplement for postlarval M. rosenbergii, and other studies have demonstrated that liver or liver-derived material can be beneficial for other crustaceans (Conklin et al 1978;D'Abramo and Baum 198 1).…”

Frozen beef liver fed at dietary levels of 5, 10, 15, 20, and 25% (dry weight) to postlarval Mucrobruchium rosenbergii was evaluated as a supplement to Mna Trout Chow No. 2. Final mean wet weights and yields of prawns fed 15, 20, and 25% beef liver were significantly higher than those of prawns that received 5 and 10% levels. Survival rates and food conversion ratios of dry matter fed to wet biomass produced were not significantly different among treatments. The suitability of 47 fresh and frozen fruits and vegetables as dietary supplements was tested. Fourteen fruits and vegetables sank and were readily consumed by prawns, and seven (fresh orange and sweet potato, and frozen banana, carrot tops, butternut squash, yellow squash, and turnip greens) were tested as supplements (10% dry weight of the total ration) to trout chow and 15% beef liver. There were no significant differences (P < 0.05) in final mean weight, survival, yield, or food conversion ratio. Pigmentation of prams fed carrot tops or turnip greens was enhanced. No significant differences in final mean weight, yield, or survival were found when frozen banana was evaluated at levels of 0, 5,10,15, and 20% as a supplement to trout chow and 15% beef liver. Food conversion ratios for prawns fed 15 and 20% levels of banana were not different from those fed 10%, but were significantly higher than for prawns fed the 0 and 5% levels. Thus, a diet of Purina Trout Chow No. 2 plus 15% beef liver gives good results with postlarval M. rosenbergii in aquaria. Largescale testing and an economic analysis are needed to determine if this diet is practical for commercial prawn nurseries.

Background. Because of the advancement of multiple spawning of carps, the importance of a quality larval diet is increasing day by day. The larval fish do not have the necessary enzyme or the amount of digestive enzymes to digest feed at optimum level. Therefore, fermentation of feed ingredients and/or formulated diets by bacterial enzymes to produce simpler forms of nutrients may be beneficial for them. Materials and methods. Five isocaloric (4.38 kcal•g-1) and isonitrogenous (35% crude protein approximately) experimental diets (D1-D5) containing 32% fish meal, 34% mustard oil cake, 30% rice bran, and 2% cod liver oil, were fermented in vitro with Bacillus circulans cells (at the rate of 10 8 bacterial cells per g) at 37°C for 1-5 day duration (1 day: D1, 2 days: D2, 3days: D3, 4 days: D4, and 5 days: D5). The bacterial strain [extracellular enzyme producer Bacillus circulans (Lr 1.1)] used for fermentation was isolated from the intestine of rohu, Labeo rohita fingerlings. The reference diet (RD), containing same ingredients, was not fermented with bacterial cells. Rohu spawn (av. wt. 0.35 ± 0.01 mg) were fed ad libitum for 21 days in the laboratory condition at 30 minutes interval starting from 0900 h to 1600 h. Results. Fermentation of diets resulted in an increase in crude protein and free amino acid contents and decrease in crude fibre content. Diets D4 and D5 resulted in best growth and survival (98% and 98.33%, respectively) of rohu spawn compared to those fed with the reference diet (RD) and other experimental groups. A significant positive correlation was obtained between RNA : DNA ratio and specific growth rate (SGR) of 18 dietary groups (6 groups in triplicate). Conclusion. Fermentation of feed ingredients may be practiced as a tool for starter diet formulation to obtain better growth and survival of rohu spawn. The enzymeproducing strain, Bacillus circulans could be used to ferment diets for 4 to 5 days to increase the bioavailability of nutrients.
