With a view to evaluate the compensatory growth response, production and survival of prawn (Macrobrachium rosenbergii) and catla (Catla catla) under polyculture system, an experiment was conducted at the Faculty of Fisheries Field Laboratory in Bangladesh Agricultural University campus from 20 March 2006 to 20 June 2006. The experiment was consisted of three treatments with three replications for each. The three treatments were: fed to satiation twice a day (T1), fed every alternate day (T2) and fed every two days of interval (T3). SABINCO prawn feed was used as supplementary diet for the experiment. The stocking densities for prawn and catla were 40/dec. and12/dec., respectively. The initial weights at stocking were: 50 g for catla in all the treatments, and 5.8, 6.4 and 6.2 g for prawn in T1, T2 and T3, respectively. The water quality parameters were almost similar in all treatments and also were within an acceptable range of fish culture. The survival rate for catla was 100.0% in T1, 91.6% in T2 and 83.3 % in T3, while for prawn was 85.0% in T1, 71.0% in T2 and 69.0% in T3, respectively. The average weight of prawn was much lower in T3 and T2 than those in T1. The best FCR value was found in T2 (1.80) followed by T3 (1.85) and T1 (1.98) in this order. The average highest gross yield was obtained from T1 (1656kg/ha) followed by T2 (1077kg/ha) and T3 (1127kg/ha), while the production of prawn was T1 (791kg/ha), T2 (517kg/ha) and T3 (429kg/ha), respectively. However, no significant differences were found in the total yield in T2 and T3. The total costs of production for the three treatments were: T1 (125.93Tk/kg), T2 (143.21Tk/kg) and T3 (146.71Tk/kg), while the profits were: T1 (104.07Tk/kg), T2 (55.86Tk/kg) and T3 (24.60Tk/kg) in which the benefit cost ratio were found to be 1:0.83, 1:0.39 and 1:0.17, respectively. The results indicate that every day feeding had provided good growth and economic returns and thus seemed to be most practicable and viable feeding options for prawn-fish polyculture. Therefore, prawn-fish polyculture with regular feeding provides satisfactory growth and production.

An experiment was conducted to compare the performance between traditional farming and organic farming of freshwater prawn in respect of production and economics. The experiment had two treatments, namely: Traditional (TT) and Organic (TO) with same stocking density (20000 juvenile’s ha-1) in triplicate. In treatment TO, formulated feed with locally available ingredients were used, and maize flour and bamboo branches were provided for maintaining C:N ratio to 20 and for developing periphyton, respectively. In treatment TT, only commercially available prawn feed was applied. No fertilizers or other types of chemicals or antibiotics were used in both treatments. There were no significant differences (P?0.05) of different water quality parameters between both treatments. Weight gain and specific growth rate (% body weight day-1) of prawn was significantly higher (P<0.05) in TO than TT treatment. Survival rate and feed conversion ratio of prawn did not vary significantly between both treatments. Highest total yield was obtained from TO treatment (511.41 kg ha-1 90 d-1) compared to TT treatment (426.57 kg ha-1 90 d-1). Net yield was also significantly higher in treatment TO (428.32 kg ha-1 90 d-1) than TT (347.77 kg ha-1 90-1). Although there was no significant difference in benefit-cost ratio between both treatments, totalreturn was significantly higher in TO than TT treatment.J. Environ.

Experiments were conducted for the study of nutrient budget in farmers' ponds (0.4–0.6 ha) in Orissa, India, at stocking densities of 0.30–0.38/m2 for scampi (Macrobrachium rosenbergii) and 0.60–0.70/m2 for Indian major carps (Catla catla, Labeo rohita and Cirrhinus mrigala). The average initial body weights of scampi and the major carps were 0.02 and 8–10 g, respectively. The culture period was 272–292 days. Feed was the main input. The FCR (feed conversion ratio) varied from 1.78 to 1.83. Feed and cow dung were applied to these ponds as organic inputs. At harvest time, the average weight of scampi and carps varied from 73 to 92 g and from 718 to 820 g, respectively. Among all the inputs, feed alone accounted for 97.60% total nitrogen (N), 97.90% total phosphorus (P) and 94.72% total organic carbon (OC), respectively. The harvest of scampi and carps accounted for recovery of 52.45% N, 19.43% P and 18.12% OC, respectively. N, P and OC accumulated in sediment were 38.31, 71.40 and 69.50%, respectively. The median nutrient loads in the fish pond effluents were equivalent to 0.58 kg of inorganic N, 0.135 kg of P and 8.83 kg of total OC per ton of Indian major carps and scampi production.

A fishers’ women-led Participatory Action Research (PAR) was conducted in 30 homestead ponds to assess the potential for polyculture of Tilapia (Oreochromis niloticus) and major carps Rohu (Labeo rohita) and Catla (Catla catla) in two coastal fishing villages of Bangladesh. Three treatments, namely T1 (Tilapia 200 fish per decimal; 1 decimal=40 m2), T2 (Tilapia 200+ Rohu 32+ Catla 8 fish per decimal) and T3 (Tilapia 200+ Rohu 8+ Catla 32 fish per decimal), each with 5 replicates, were tried in Hossainpur and Anipara villages. Formulated commercial Mega-feed was applied to the ponds twice daily at an initial rate of 10% body weight (bw)/day of Tilapia down to 4% bw/day throughout the culture period. The water quality parameters of ponds including temperature, transparency, pH, salinity and dissolved oxygen significantly varied among treatments except temperature and pH and remained within optimum range for carp polyculture except salinity. The survival rate, harvesting weight and yield of Tilapia were significantly highest in T1 (85.63±05%, 258.59±18.76 g & 11073±805 kg/ha, respectively) in Anipara and lowest in T3 (75.63±0.37%, 136.97±10.63 g & 5180±406 kg/ha, respectively) in Hossainpur. The gross fish production was the significantly highest in T1 (11354±806 kg/ha) of Anipara and lowest in T1 (6325±227 kg/ha) of Hossainpur. Statistically, the highest net return (866,627±84874 BDT/ha) was found in T1 of Anipara and lowest in T3 (279,389±46104 BDT/ha) of Hossainpur with a significantly higher benefit-cost ratio (BCR) obtained in T1 (3.26±0.20) for Tilapia and lower in T3 (1.58±0.10) for polyculture Tilapia and carp of Hossainpur. Therefore, it may be concluded that Tilapia production in small homestead coastal ponds has a higher potential than its mix with carps in polyculture for generating food and supplemental income opportunity for coastal fishers’ women in Bangladesh.

Stunted juveniles of Catla catla (Hamilton, 1822) were produced through 150 days of stunting with five combinations of density and photoperiod. These stunted juveniles were subsequently polycultured in grow-out ponds for eight months along with rohu (Labeo rohita) and mrigal (Cirrhinus mrigala). In grow-out trial, the five treatments with different combinations of stocking density and photoperiod comprised, control (20 m-3, 12L/12D), T-1 (30 m-3, 12L/12D), T-2 (40 m-3, 12L/12D), T-3 (20 m-3, 6L/18D) and T-4 (20 m-3, 0L/24D). After eight months of culture, growth curves of stunted catla in all treatments were non-convergent and inferior to control, indicating no compensatory growth response. Although survival (70-73%), average body weight, (ABW; 667-755 g) and weight gain (648-729 g) in grow-out phase were statistically similar in the groups with different stocking density (Control, T-1 and T-2) (p>0.05), the grow-out survival was relatively higher in T-2 (73.3%), indicating its positive correlation with higher stunting density. In contrast, juveniles stunted with reduced photoperiod (T-3 and T-4) showed significantly lower ABW and weight gain (p<0.05). The poor survival in T-3 and T-4 (40-43%) indicated significant effect of stunting with reduced photoperiod on subsequent grow-out survival and yield performance. Based on the results, the study recommend the use of rearing density up to 40 m-3 for juvenile stunting in catla.

The objective of this work was to verify the occurrence of compensatory growth in Malaysian prawn (Macrobrachium rosenbergii) reared in pens, after being stocked in cages under high densities during nursery phase. The experiment was carried out in 0.5 m² cages and 2-m² pens set in natural bottom pond with 2,400 m². Prawn post-larvae (PL) with an average weight of 0.026 ± 0.012 g (nursery phase) were initially stocked in 16 cages at the densities of 50, 400, 800 and 1,200 PL m-2. Sixty days later, prawns were transferred to 16 growing pens, at the density of 12 prawns m-2. Initial average weight of the prawn in this phase was the final average weight registered in the nursery phase, as follows: 50 PL m-2 = 2.3 ± 0.3 g; 400 PL m-2 = 0.5 ± 0.03 g; 800 PL m-2 = 0.3 ± 0.05 g and 1,200 PL m-2 = 0.1 ± 0.01 g. Commercial rations for prawns (35% crude protein) were given once a day, in the afternoon. After 244 days, survival, average weight and biomass did not differ significantly among prawns with different initial average weight. Relative growth rate was significantly greater in prawns previously stocked at 1,200 PL m-2 and feed conversion efficiency was significantly better for those previously stocked at 400 and 1,200 PL m-2. These results suggest the existence of partial compensatory growth in M. rosenbergii, what can successfully carry on stocking of prawns of this species at high densities in the nursery phase.

Purpose: study the biotechnical features of rearing juvenile giant freshwater prawn (Macrobrachium rosenbergii) using recirculating aquaculture systems (RAS).Materials and methods. Two fish-farming modules RAS and aquarian complex were used for the work. One of them has a total volume of 6.5 m3, the second - 14.5 m3. Larvae were reared in gasite cages of 0.021 m3 in an aquarian complex of two 200-liter aquariums. Larvae of one female prawn were used in an amount of 8500 units. At each stage of prawns' development we used different versions of feed of both animal and plant origin: artemia, minced fish, boiled chicken eggs (protein + yolk), beef liver and oat flakes.Results. Brood fish were kept at an average planting density of 6.2 individuals/m2, with a sex ratio of 1:4.5 (males: females). The planting density of larvae in cages was 2,125 units/cage or 101.2 units/liter. The average weight of juveniles during rearing of postlarvae at 130 days was 3.19 g. Juvenile yield was 49.9%. Specific growth rate of biomass varied from 4.87 to 3.68 %. Planting density of juveniles varied from 1775,6 units/m2 to 660,9 units/m2. As a result, the feeding coefficient was 5.24 units. Growing productivity was 362.7 pcs/m2 or 1156.8 g/m2 in the RAS module.Conclusion. There were established biotechnical peculiarities and production possibilities of growing young giant freshwater prawn (Macrobrachium rosenbergii) using fish-breeding RAS and aquarian complex. Modernization of fish-feeding RAS and use of some recommendations on feeding suggest the possibility of their use for breeding and rearing of juvenile giant freshwater prawns in already existing warm-water enterprises, initially aimed at other objects of aquaculture.

Pen culture for in situ raising of stocking material was conducted in Sareni Jheel, located in the Rae Bareli District of Uttar Pradesh. Sareni Jheel, being rich in organic carbon (4.5%) and nutrients, higher values of silt (29%) and clay (15%) were recorded. Rich oxygen levels, alkaline pH, high organic matter, moderate to high chemical parameters suggested moderately productive nature of this wetland. Pen with high-density polyethylene (HDPE) net was installed in an area of 0.1378 ha and stocked with advanced fry of the Indian major carps, rohu Labeo rohita and catla Catla catla in the ratio of 1:1 @ 25 nos. m-2. No significant changes in water quality parameters were noticed within and outside the installed pen. Mean weight at stocking of rohu and catla was 2.88±1.41 g and 2.1±1.16 g, which increased to 57.2±13.84 g and 67.38±25.79 g respectively, in 120 days. The average feed conversion ratio (FCR) recorded was 1.08 with overall survivability of 69.52% in rohu and 74.74% in catla. Benefit-cost ratio and return on investment were calculated as 1.69 and 0.69, respectively. Intervention through pen culture resulted in the increase in fish productivity of Sareni Jheel from 310 to 833 kg ha-1.

An experiment was conducted to compare growth and production performance between all-male and all-female giant freshwater prawn (Macrobrachium rosenbergii) in combination with mola (Amblypharyngodon mola) at the Fisheries Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh. The research was carried out for a period of 120 days in nine earthen ponds with an average depth of 1.2 m. The experiment had three treatments, viz. polyculture of all-male prawn with mola (stocking density 20,000 ha-1), monoculture of all-male prawn and monoculture of all-female prawn were treated as T1, T2, and T3, respectively with three replications of each and prawn stocking density was 30,000 ha-1 in all the treatments. Formulated sinking feeds were applied twice daily for prawn, and assuming 80% survival feeding rates were gradually reduced to 10-5% of body weight from the beginning to the last month. All water quality parameters (except transparency, chlorophyll-a and plankton) did not vary statistically significantly (P>0.05) among the treatments. Survival of prawn in respective of gender was lower in monoculture than in polyculture with mola, but did not vary significantly (P>0.05). Considering growth and production performance in all treatments, the male prawn showed better growth and production performance than female prawn and the highest gross and net production was recorded in treatment T1, therefore, polyculture of all-male prawn with mola is better than monoculture.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10163  J.

This study was conducted to assess the aquaculture potential of the freshwater prawn Macrobrachium rosenbergii (de Man, 1879) with the Indian major carps (Catla, Catla catla; Rui, Labeo rohita and Mrigal, Cirrhinus mrigala) and silver carp, Hypophthalmichthys molitrix in northwestern Bangladesh. Further, the effect of the culture system on overall production and economic feasibility was evaluated. A 3×2 (treatment×replicate) experimental setup was conducted using six earthen ponds measuring 100 m2 each for a culture period of six months from September, 2007 to February, 2008. The treatments were as follows: T1 was stocked with only carps (catla, rohu, mrigal and silver) at the 3000 (catla), 2000 (ruhu), 3000 (mrigal) and 2000 (silver) ha-1; T2 and T3 were stocked with catla and silver carp were 3000 and 2000 ha-1, respectively; and additionally M. rosenbergii (juvenile) was stocked at 15000 and 20000 ha-1 in T2 and T3, respectively. All the ponds were subjected to the same fertilization treatment. Fish were fed twice per day at a rate of 5-12% of the prawn and fish body weight. The net weight gain of catla and silver carp were 69.08±11.63 and 108.67±15.00 g in T1, 61.76±12.58 and 98.80±17.05 g in T2, while 58.11±12.51 and 93.09±14.84 g in T3, respectively. The mean individual weight of harvested prawn was significantly higher in T2 (14.61±02.06 g) than T3 (14.04±01.83 g) (P<0.05). Also the survival rate of prawn was higher in T2 (74.15%) than T3 (69.25%) (P<0.05). The net production of prawn was higher in T3 (1141.28±46.35 kg ha-1) than T2 (964.54±25.53 kg ha-1), but the specific growth rate was significantly higher in T2 (2.07%) than T3 (1.99%) (P<0.05). Higher profit was obtained in T3 (35682.18 Tk ha-1) than T1 (8537.53 Tk ha-1) and T2 (30801.56 Tk ha-1); however, cost-benefit ratio (CBR) was significantly higher in T2 (3.19) where stocking densities of prawn was 15000 ha-1 than T1 (2.92) and T3 (2.47). The results of this experiment indicate that the polyculture of the freshwater prawn with the Indian major and Chinese carp present a more profitable venture which is more economically feasible than the monoculture of the freshwater prawn.DOI: http://dx.doi.org/10.3126/on.v9i1.5735

An experiment was conducted for two months in a recirculatory system consisting 12 glass aquaria (size 41× 41 × 46 cm) to evaluate the effects of substrates on the growth and survival of Macribrachium rosenbergii postlarvae (PL). Treatment T1 having no substrate was considered as the control. Treatment T2 contained pieces of hollow PVC pipe, treatment T3 and T4 were provided with high density polyethylene (HDPE) and black nylon netting, respectively. Each treatment had three replicates. PL-15 of M. rosenbergii (mean initial length 1.20 ± 0.02 cm; mean initial weight 27 ± 0.02 mg) were stocked at the rate of 75 PLs (1.25 PL L-1) in each aquarium. At the beginning PLs were fed three times daily at the rate of 20% of their body weight which was reduced to 10% at the start of 2nd month. The ranges of water quality parameters recorded in different treatments were: temperature 26 - 29°C; dissolved oxygen 6.2 - 8.1 mg L-1; pH 6.8 - 8.1 and total ammonia 0.01 - 0.15 mg L-1. The result of the study showed that there was no significant difference (P>0.05) in final length of PLs between treatments T3 (HDPE netting) and T4 (nylon netting) but these values were significantly higher than those in T1 (control). There was no significant difference (P>0.05) in final weight and specific growth rates (SGR) of PLs in treatments T3 and T4 but these values were significantly higher than those in T2 (PVC pipe) and T1 (control). Final weights of PLs were 32.70%, 31.54% and 21.05% higher in treatments T3, T4 and T2 respectively than T1 (without substrate). The FCR values ranged between 1.85 and 1.88. There was no significant difference (P>0.05) between the survival of PLs which ranged between 80.33 and 83.00%. Result of the study indicated that growth of M. rosenbergii PLs improved in presence of artificial substrates but the artificial substrates did not improved survival. HDPE and nylon netting gave the best results compared to PVC pipes and control treatments in terms of growth and feed efficiency. Therefore, use of HDPE or nylon netting may be recommended as substrate for successful nursing of M. rosenbergii PLs. However, further studies using different substrates should be carried out in nursery ponds to ascertain the usefulness of these substrates for nursing of M. rosenbergii PLs.
