An experiment of 65 days duration was conducted to study the effect of biofilm formed on different natural substrates at different substratum densities on the growth and survival of juveniles of freshwater prawn Macrobrachium rosenbergii (de Man, 1879). Natural substrates like dried paddy straw and cut grass were evaluated as substratum for biofilm production. The experiment was conducted in fiber glass tanks of 500 l capacity. The study comprised six treatments viz., dried paddy straw at 60 (T1); 120 (T2) and 240 (T3) g tank-1 and cut grass at 60 (T4) and 120 (T5) g tank-1, each with three replicates following a completely randomised design. Prawn juveniles reared without any substratum acted as control. Ten days after the introduction of substratum in the tanks, prawn juveniles (2.01 g±0.37) were stocked at a density of 40 m-³. The juveniles were fed with 2 mm commercial pellet feed (30% protein) at 5% of the biomass. No water exchange was done in the treatment tanks whereas in control tanks 50% water exchange was done once every week. The study revealed significantly (p<0.05) higher survival rate (%) in the treatment tanks (94.4±9.6, 80.5±12.7, 86.1±12.7, 86.1±4.8 and 91.6±8.35 for treatments T1, T2, T3, T4 and T5 respectively) compared to the control (52.8±9.5). Among treatment tanks, T2 and T3 showed significantly higher (p<0.05) average daily growth (g d-1) (0.055±0.005 and 0.057±0.005 respectively) when compared to other treatments (0.0367±0.02 for T1 and 0.0373±0.01 for T5). But the specific growth rate did not show any significant difference among the treated groups including control. Use of biofilm significantly reduced the usage of water (by 2.9 times) compared to control, which is significant considering the predicted water scarcity in future.

Effect of artificial substrates on growth and survival of giant freshwater prawn Macrobrachium rosenbergii (de Man, 1879)in the nursery and grow-out rearing was evaluated. Nursery rearing was conducted for a period of 35 days in nine 1 m3cement tubs with 15 cm soil base. Three tubs without substrates served as control (C) while three tubs each with 200 g ofsugarcane bagasse (SB) or 200 g of paddy straw (PS) formed the treatments. Each tub was stocked with 15 post-larvae(mean weight, 0.01 g). Grow-out rearing was conducted for 90 days in six 25 m2 cement cisterns, of which three cisternswithout substrate served as control (C) and three with 5 kg sugarcane bagasse (SB) served as treatment. Each cistern wasstocked with 25 juveniles (mean weight, 0.55 g). The average phytoplankton and zooplankton abundance in water as wellas algae and food organisms attached on the substrate in the nursery phase was greater in bagasse than in paddy strawtreatments. Addition of substrate resulted in higher growth and survival both in nursery and grow-out phase. Prawns grownin cisterns provided with substrates were of more uniform size than those in control cisterns. The study recommends the useof substrate based aquaculture for nursery and grow-out rearing of M. rosenbergii.

There are obstacles in the aquaculture business that is still often facedbyfarmers, one of the challengesisthe high price of commercial feed. Feed as an energy source for growth is a reasonably high-cost component in production that reaches 40-89 %. In the control of food for efficiency, it could be done by the fasting method. This research was aimedtoanalyze the effect of periodic fastedofgiant prawn (Macrobrachium rosenbergii de Man, 1879) against growth and feed efficiency. This research was conducted at IBAP Installation, Probolinggo District - East Java Province. The experimental method used completely randomized design with five treatments and three replications, such as; P0: feeding without fasting (as control), P1: a-day fasted, a-day feeding, P2: a-day fasted, two-days feeding, P3: a-day fasted, three-day feeding, P4: a-day fasted, four-days feeding, P5: a-day fasted, five-day feeding. The results showed that periodic fasted of M. rosenbergii no significant effect on the daily growth rate, absolute weight growth, and feed efficiency. However, by looking at the rate of growth, thisfasting methodcouldbe used as an alternative to saving feed. The P5 showed the most effective in increasing daily growth rate, absolute weight growth, and effectiveness of giant prawn feeding. The strategy of periodic fasted to increase the production of giant prawns should consider the other supporting factors such as ideal water quality (pH, temperature, and DO), proper stocking density, and feeding periods on schedule.

An experiment was conducted to evaluate the effect of addition of tilapia on abundance of periphyton in freshwater prawn, Macrobrachium rosenbergii (de Man) in periphyton based culture system for a period of 120 days at Fisheries Field Laboratory Complex, Bangladesh Agricultural University, Mymensingh. A large pond (83×8.9 m) was drained completely and partitioned by galvanized iron sheet into 18 small ponds of 40 m2 each; of which 6 ponds were used for this experiment. The experimental ponds were divided into 2 treatments each with 3 randomly selected ponds. The absence and presence (0 and 0.5 individual m-2) of tilapia (Oreochromis niloticus) were investigated in 40 m2 ponds stocked with 3 prawn juveniles (5±0.05 g) m-2 with added substrates for periphyton development. A locally formulated and prepared feed containing 30% protein was supplied considering the body weight of prawn only. Addition of periphyton substrates significantly reduced the inorganic N-compounds (TAN, NO2-N, and NO3-N) in water column. Forty six genera of periphyton were identified belonging to the Bacillariophyceae (10), Chlorophyceae (21), Cyanophyceae (7), Euglenophyceae (2), Crustacea (1) and Rotifera (5) with significant difference (P<0.05) of phyto-periphyton except Euglenophyceae and without significant difference (P>0.05) of zoo-periphyton between the treatments. The abundance of periphyton biomass in terms of dry matter, ash, ash free dry matter and chlorophyll-a were significantly higher in tilapia-free ponds comparing to tilapia added ponds. Benthic organisms had no significant difference (p>0.05) between the treatments. Addition of tilapia in periphyton-based system benefited the freshwater prawn culture through (i) reducing toxic inorganic nitrogenous compounds in water (ii) reducing demand for supplemental feed (iii) using periphyton as additional natural feed and, (iv)improving survival and production of prawn and tilapia.DOI: http://dx.doi.org/10.3329/jbau.v10i2.14924 J.

An inclusive indoor experimental trial was carried out to determine the influence of levamisole, an antihelminthes, as a growth facilitator in the culture of scampi (Macrobrachium rosenbergii, Palaemonidae). A purified diet was prepared with 40% protein, containing levamisole at 0 mg (as control), 125 mg and 250 mg·kg-1 dry weight. Nine plastic tanks were stocked with a group of 32 animals (PL20-30) each and fed the trial diet for three months. Animals were regularly weighed at the end of each month. No significant difference was noticed in mean growth and survival (P > 0.05) of the animals between treatments. However, significant differences (P < 0.05) were observed in the growth parameters like percentage of weight gain, percentage of SGR and FCR among the control and levamisole treated animals. Survival percentages of the animals treated with levamisole were better than the control.

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.

T1 And T2

An experiment was conducted for six months to evaluate the effects of artificial substrates on the survival, growth and production of Macrobrachium rosenbergii juveniles. The treatment T1 contained locally available bamboo-made substrate both vertical and horizontal and treatment T2 received no substrate. Juvenile prawns (0.40±0.13 g) were stocked at the rate of 19,760 prawns ha-1. The water quality parameters range such as temperature, pH and DO were 22.06-33.45°C, 7.70-8.40 and 4.75-6.15 mgl-1 respectively which was no significant difference (P<0.05) between two treatments. The final weight was 56.48±6.56 g and 45.03±2.11 g in T1 and T2 respectively. The survival rate of T1 was 63.12% which was significantly higher (P>0.05) than T2 (56.87%). The specific growth rate, food conversion ratio and protein efficiency ratio were 1.19 % and  1.14 %, 3.15 and 4.39, 0.98 and 0.71 in T1 and T2 respectively which were not significantly different (P<0.05) between treatments. The total production and net profit in T1 was 1408 kgha-1 and BDT 117,325 ha-1 which was significantly higher (P>0.05) than T2. Thus growth and survival of prawn juveniles improved in presence of artificial substrate which could be economically viable technique for the freshwater prawn culture.
