Optimum feeding schedule is one of the main things for the proper growth of fish and other animals. A study was conducted to optimize the effects of different feeding frequencies on growth performance and production of Rui (Labeo rohita) under pond cage culture system in Rajshahi, Bangladesh. Labeo rohita with an average weight of 302.23±4.07g (mean ± SD) were randomly stocked in 9 cages at 30 fish/cage in all the treatment. Fish were fed (4% of body weight) a commercial floating feed with three different feeding schedules: feeding of fish thrice daily in T1treatment; twice in T2 treatment and once in T3 treatment. Water quality parameters were measured during the study period. The physico-chemical parameters of pond water were within suitable ranges for fish culture in cages. The obtained values of the water quality parameters were temperature 28.26 to 28.46°C, pH 6.91 to 6.94, DO 5.04 to 5.33 mg/l, CO2 2.95 to 3.02 mg/L. The mean final weight gain was significantly highest in T1 (345.05 g) a followed by T2 (324.66 g) and T3 (257.82 g). The Specific growth rate (SGR) value were significantly higher in T1 treatment (0.91% bwd-1; Body weight per day) than T2 (0.87% bwd-1) and T3 treatment (0.73% bwd-1). The feed conversion ratio (FCR) value was significantly lower in T1 fish group (2.72) than other two T2 (2.84) and T3 (3.44) treatments. The fish productions were 18.13, 17.55 and 15.67 kg/cage/cycle in T1, T2 and T3 respectively. The highest net profit was found (Bangladeshi Taka, BDT 1445.38) in T1 compared to T2 (BDT 1329.24) and T3 treatment (BDT 937.99). The cost benefit ratio (CBR) was significantly higher in T1 (0.57) than T2 (0.53) and T3 (0.37). The feeding schedule three times in a day was most suitable than other two schedules.

Abstract To investigate the effect of supplementation of dried biofloc produced by freeze-drying method on water quality and growth performance of red hybrid tilapia, two experimental diets (T0 treatment: 0 % biofloc; and T1 treatment: 4 % freeze-dried biofloc) were examined during 57 days of feeding trial. Diet T0 resulted in higher feed intake than T1 treatment (P < 0.05), while no significant differences were found between the two treatments in terms of weight gain, SGR, and FCR (P > 0.05). For water quality parameters, values of temperature, EC, TDS, ammonia and nitrate were significantly higher for T1 treatment (P < 0.05). While dissolved oxygen level was significantly lower for T1 treatment compared to T0 treatment (P < 0.05). Moreover, no significant differences were found for pH and salinity (P > 0.05). However, the two treatments showed water quality parameters levels within the range of standard levels of water quality for tilapia culture. In addition, proximate composition of experimental diets showed significantly higher lipid content for T0 treatment than T1 treatment (P < 0.05). While no significant differences were found between means of treatments for organic matter, protein, fiber, ash and energy contents (P > 0.05). Based on these results, a 4 % supplementation of freeze-dried biofloc can be successively included in formulated diets for red hybrid tilapia without any effects on growth in terms of weight gain, specific growth rate, feed conversion ratio and survival, and can result in acceptable water quality levels for red hybrid tilapia.

The current study focused on assessing the outcome of methanol extract of Chaetomorpha antennina (MECA) on the growth performance and immune modulation in both specific and non-specific immune responses through the assessment of neutrophil, serum lysozyme, serum myeloperoxidase, antiprotease, ceruloplasmin, reactive oxygen species (ROS), and reactive nitrogen species (RNS) activity in Labeo rohita (rohu) at 28 days post treatment along with assessment of the disease resistance capacity against Edwardsiella tarda at 30days post immunization. Fishes (n = 144; average weight 50.0 ± 0.23 g) were evenly divided into four treatments, with 12 fishes per tank in triplicates. The MECA was injected intraperitoneally in the fishes at different doses as 0, 25, 75, and 150 mg/kg of the body weight. The results demonstrated that fish treated with MECA have an increased body weight, specific growth rate, and feed conversion ratio (p < 0.05) with respect to the control group. Results suggested that the MECA inclusion can significantly enhance (p < 0.05) the levels of serum lysozyme, neutrophil function, serum antiprotease activity, cellular RNS, and ROS production. Exposure to MECA of 75 mg/kg showed a significantly higher survival percentage against E. tarda disease infection. These results indicate MECA as a stimulant of immunity in L. rohita against E. tarda. The results suggested that MECA is a potent immunostimulant in finfish aquaculture and can offer higher economic welfare.

This study aims to determine the adaptation of Seluang fish (Rasbora agryotaenia) based on the domestication stage of Sebangau waters. This research started in January until February 2018. The research method used is a survey and experimental observation. The size of the tarpaulin pond used for domestication is 2 x 3 m, with a water height of 30 cm. The number of fish sampled is 200 heads. Feed is given as much as 5% of the total weight of the fish kept, feeding done twice a day (morning and afternoon). This domestication activity is still not perfect, because only part of the life cycle of fish (Rasbora agryotaenia) can be done in the cultivation system (survival and eating commercial feed). During maintenance activities, the amount of feed used was 63.840 g with the final weight of the fish was 16.905 g. Survival rate (SR) of fish (Rasbora agryotaenia) during maintenance was 73.5% and deaths 26.5%. From the calculation is known that the Feed Conversion Ratio (FCR) for fish (Rasbora agryotaenia) 2.8. This domestication stage starts with the preparation of maintenance pools, fishing in nature, sorting, distribution, and maintenance. During maintenance, five samples of sample fish were taken and five times the pool water quality measurement. From the five weights of the sample fish, it is known that the average weight of the fish is kept, I = 0.003 g, II = 0.042 g, III = 0.051 g, IV = 0.082 g, V = 0.115 g. From the measurement of water quality of tarpaulin ponds, it is known that the mean value of water quality parameters, for DO ranges from 1.5 to 8.8 mg / L, the pH ranges from 5.5 to 7.2 and temperatures range from 27.4 to 27.7 0C.

Growth performance and survival of Tor putitora fry under different stocking densities were evaluated fry rearing system. The experimental period was 10 weeks from 31 December to 10 March 2019. The experiment was carried out in nine earthen ponds of 0.04 ha each under three treatments with three replications.  Thirty days old fry were stocked at the rate of 1.0X105/ha was designated as treatment- 1 (T1), 1.5X105/ha` as treatment- 2 (T2) and 2.0X105/ha as treatment- 3 (T3), respectively. Fry were fed with commercially available nursery feed containing 32% crude protein. It was observed that, lower stocking density showed highest daily weight gain in T1 (growth 0.066 ± 0.006 g/day) compared with higher stocking density in T2 (growth 0.044 ± 0.004 g/day) and T3 (growth 0.024 ± 0.003 g/day), respectively. It is also noticed that, the lower stocking showed the highest survival rate (79.66 ± 4.34 %) than the other two treatments (66.97±3.67 and 54.67± 3.12 %). The values of different water quality parameters were within the optimum ranges for the rearing of carp fry. Water quality parameters did not show significant variations in the experimental ponds under different stocking densities. Among these three stocking densities lower stocking density (T1) showed the best result compare with the other two higher stocking densities.

This trial aimed to evaluate effects of stocking densities of 1-5 fish/m2 on growth performance, survival rate and economic efficiency of Asian seabass (Lates calcarifer) in earthen ponds. Fish with an initial length of 90.7 ± 0.1 mm and weight of 20.8 ± 0.1 g/fish and ponds with 600 m2 each and 1.5 m depth were used for this study. Experiment was designed with three treatments, including different stocking densities of 1, 3 and 5 fish/m2. The fish was fed with pellete feed containing 43 - 44% crude protein. Water quality parameters including temperature, dissolved oxygen, pH, salinity, transparency and ammonia concentration were measured once a week. Fish were sampled every 30-day intervals for length and weight measurement then for their growth estimation. Costs were recorded for economic efficiency estimation. Results showed that the water quality parameters were in suitable ranges for growth and development of Asian seabass. The final average length and weight of density 1 fish/m2 was significantly higher than those at 3 and 5 fish/m2 (P < 0.05). However, there was no significant difference on the fish growth in terms of daily length and weight gain, as well as survival rate and feed conversion ratio between different stocking densities. Asian seabass culture at 3 and 5 fish/m2 resulted in a higher profit compared to at 1 fish/m2. The highest economic efficiency in terms of area pond was showed at 5 fish/m2 treatment.
