Lack of quality carp seeds is one of the major problems for fish production in Bangladesh. This experiment was conducted during July to December 2013 to study the production and economics of carp polyculture using wild and hatchery produced seeds in ponds in Faridpur district, Bangladesh.  Seeds of native major carps (NMCs) (Catla catla, Labeo rohita and Cirrhinus mrigala) and non-native carps (NNCs) (Hypophthalmichthys molitrix, Ctenophryngodon idella, Aristichthys nobilis and Cyprinus carpio) from four different sources were tested in feed and fertilizer based polyculture ponds under controlled mesocosm trials with four treatments (T1–T4), each with four replications. Combination, weight and density of the stocked species were same for all the treatments. Water quality parameters were monitored monthly and mean values were found within suitable range for fish farming. Mean final weight, weight gain, specific growth rate and yield of L. rohita, C. catla and C. mrigala were found significantly (P < 0.05) higher with treatment T1, T3 and T2 respectively. Treatments T1, T2 and T3 varied more significantly (P < 0.05) than treatment T4 for total fish yield and cost benefit ratio.  Polyculture of wild sourced NMCs and hatchery produced NNCs were found more profitable than aquaculture of hatchery produced NMCs and NNCs.

Raised stocking materials, fingerling of Indian major carp seeds (Catla catla, Labeo rohita Cirrhinus mrigala) in pens, installed in two floodplain wetlands of Assam viz. Goruchora (Golaghat district) and 46-Morakollang (Morigaon district). The pens were stocked at 30,000 fry•ha-1, in a ratio of 3:2:1 of C. catla, L. rohita and C. mrigala fry, respectively. The average initial length and weight of fry at the time of stocking for C. catla, L. rohita and C. mrigala were 5.45 cm (1.80 g), 4.51 cm (1.15 g) and 4.65 cm (1.12 g), respectively. The fish stocks inside the pens were given supplementary feeds, mustard oil cake and rice polish (1:1) at 5% body weight. The pens were harvested after a rearing period of 145 days with an average growth of C. catla (19.0 cm, 85.1 g), L. rohita (15.8 cm, 52.8 g) and C. mrigala (15.8 cm, 42.9 g) in Goruchora wetland, while in 46- Morakollang wetland it was recorded as 17.0 cm (63.8 g) for C. catla, 15.4 cm (55.9 g) for L. rohita and 14.0 cm (41.5 g) for C. mrigala for further grow-out in the lakes proper. During the period of experimentation, the fluctuations in water quality parameters like water temperature (17.6-29.0o C), transparency (72-102 cm), dissolved oxygen (3.60-16.50 mg•l-1), pH (7.12-9.53), total dissolved solids (46.6-111.3 mg•l-1) and specific conductance (102-232 µS•cm-1) were monitored, too. The production in terms of fish biomass (fingerlings) was estimated at 2106 and 1780 kg•ha-1 in Goruchora and 46- Morakollang wetlands, respectively. The cost-benefit ratio was calculated as 1.40 (Goruchora) and 1.77 (46-Morakollang), which can be considered as significant, economically.

Open aquatic system such as beel is an important freshwater resource for agriculture and aquaculture.This study was conducted (July-December 2014) to describe the beel aquaculture management practices in the Hagla Beel at Bagmara upazila under Rajshahi district.The Beel fish farming area was 20.25 ha and irregular in shape with average depth 1.5 m. During the study period, the measured water quality parameters of the beel were within the suitable range for aquaculture. Eight genera of phytoplankton and eight genera of zooplankton were identified from the beel water body. Four native and 4 exotic fish species with sizes ranging from 0.15-1.11 kg were stocked for growing in the beel. At the end of culture period, the production of fish was 2,622.15 kg/ha and cost-benefit ratio (CBR) was 1:1.42. Environmental problems such as increasing of water temperature and decreasing of water level during summer, and parasitic diseases were some of the risks in beel fish farming system. The results of this study should be useful for beel aquaculture, and for the farmers and resource manager for harnessing maximum benefits from the beel resources in Bangladesh.

Increased temperature, decreased water level and reduced culture period of the ponds with lack of guidelines in selecting appropriate stocking size, density and combination of species are major constraints for safe production of fattening based carps in drought prone barind area of Bangladesh. In order to address these problems, an experiment was conducted during July-December, 2018 to determine the suitable species combination for fattening ponds of overwintered carps in Tanore upazila (sub district) of Rajshahi district, Bangladesh. Three different combinations of surface (G. catla and H. molitrix), column (L. rohita) and bottom (C. cirrhosus and C. carpio var. specularis) feeding carp species were tested under 3 treatments (T1, T2 and T3), each with 3 replications: T1 (Surface-30%, column-40%, and bottom-30%), T2 (Surface-40%, column-30%, and bottom-30%) and T3 (Surface-35%, column-35%, and bottom-30%). Application of good aquaculture practices in the studied ponds was found to improve the environmental conditions of pond. Significantly (P< 0.05) highest fish yield was obtained from treatment T2 which was 21.47% and 11.89% higher than T1 and T3, respectively.  Significantly (P<0.05) highest cost benefit ratio was recorded with treatment T2 (0.42±0.02) followed by T3 (0.31±0.01) and T1 (0.21±0.01), respectively. Inclusion of appropriate number of fishes at different water layers of pond favoured the yield and economics of carp fattening. The study also suggests focusing on optimal stocking density together with the formulation of low cost feed for carp fattening in ponds under barind area of Bangladesh.

Abstract An experiment was carried out in Vietnam on an integrated rice-fish polyculture system with three species: common carp (Cyprinus carpio), Nile tilapia (Oreochromis niloticus) and silver barb (Barbonymus gonionotus). Agricultural by-products were used as supplementary feed at a rate of 2-3% total body weight of fish per day. The total fish yield (823 kg ha-1) and fish production (988 kg ha-1 yr-1) at 2 fish m-2 were significantly higher (p<0.05) than at 1 fish m-2 (453 kg ha-1 and 544 kg ha-1 yr-1, respectively). The cost : benefit ratio (1.80) and the cost : profit ratio (1.75) for farm household income at 1 fish m-2 were lower than at 2 fish m-2 (2.08 and 2.02, respectively). This system should be adopted by aquaculture extension programmes to improve rural farmers' income when the market prices for common carp, tilapia and silver barb are sufficiently high to obtain a benefit at the end of the culture cycle.

The study was conducted at Ma-Fatema Fish Hatchery in Jessore from January to March, 2016. The present study was emphasized on water quality parameters, feeding management and cost- benefit analysis. The water quality parameters temperature (0C), pH, dissolved oxygen (DO) (mg/l) and transparency (cm) were measured by Celsius thermometer, pH meter, DO meter and secchi disk, respectively. The proximate composition of feed ingredients was determined by the Association of Analytical Chemists, 1980. Brood fishes were reared all year round in the brood ponds by supplying formulated feeds. Temperature was 19oC -26°C in brood ponds and 18oC-24oC in hatching jars; pH was 6.93–7.87 in brood ponds and 6.79-7.54 in the hatching jars; dissolved oxygen was 4.8-6.3 mg/l in brood ponds and 4.8-6.7 mg/l in hatching jars; transparency was 14-18 cm in the brood ponds. The percentage of farm made feed was protein (27.76%), lipid (4.9%), CHO (18.62%), ash (11.31%), fiber (6.4%), moisture (31.01%). The cost benefit ratios were 1.54, 1.32 and 1.23 and net profits were BDT 49911.67, BDT 24816.67and BDT 16366.67 respectively in January, February and March. Management of brood fish by providing quality feed and physico-chemical parameters of water were maintained in according to scientific procedure. Cost-benefit ratio of the hatchery in common carp production was satisfactory.Asian J. Med. Biol. Res. September 2016, 2(3): 414-421

Breeding Techniques

An investigation was carried out to know the induced breeding techniques of some firewater fish species such as rui (Labeo rohita), catla (Catla catla), silver carp (Hypophthalmichthys molitrix), grass carp (Ctenopharyngodon idella), common carp (Cyprinus carpio), bighead carp (Hypophthalmichthys nobilis), sharpunti (Puntius sarana) and bata (Labeo bata) at Ma Fatima Fish Hatchery in Chanchra, Jashore, Bangladesh. The cost-benefit analysis was also performed on this hatchery for three months from May to July, 2016. The brood fishes purchased from different local sources were used for spawning. The hatchery mainly practiced induced breeding by maintaining proper age and weight of brood stock during spawning. The ranges of fertilization and hatching rates of the experimental fishes were 80.04±1.44 % to 94.35±0.54% and 75.34±3.49% to 88.68±2.76%, respectively. Total spawn production was 960, 862 and 734 kg, and the total revenue income from spawn sell was BDT 2,883,500, 2,355,100 and 1,844,800 (BDT 85 = 1 US$) in May, June and July, respectively. Estimated capital cost was BDT 87,90,000, while the operating costs were BDT 1,810,650; 1,555,105 and 1,267,680 in May, June and July, respectively. The calculated cost-benefit ratios in May, June and July were 1.59, 1.51 and 1.46, respectively. The hatchery got the highest net profit of BDT (Bangladeshi Taka) 1,041,906 in May due to the highest production and higher price of spawn, and the lowest profit of BDT 546,176 was obtained in July. So, May was found to be the peak breeding month of Ma Fatima Hatchery. The estimated cost-benefit ratio indicated that the spawn production through induced breeding techniques was profitable for the hatchery owners.

This study was aimed to evaluate the efficiency of three protein level feeds on the fingerlings production of riverine endangered Notopteruschitala (Hamilton, 1882) for a period of two months in ponds. Chital fry (Initial wt, 5.6±0.19 g) were randomly stocked at the rate of 7410 per hector. Feeding trials were conducted under 3 treatments (T1: feed contains 35% protein, T2: feed contains 30% protein, T3: feed contains 25 % protein) each with 3 replications. No significant (P<0.05) difference was observed for all the water quality parameters among the treatments. A suitable range of water quality parameters (temperature, water transparency (cm)), dissolved oxygen (mg/l), pH, alkalinity (mg/l), ammonia) were recorded with the environment of experimental ponds. The treatment had significant effects on weight gain, ADG, SGR among treatments. Highest weight gain (19.31 ± 0.23 g) was observed in T1, lowest (13.96 ± 0.15 g) in T3. SGR (1.65±0.02) and ADG (0.18±0.005) were significantly (P<0.05) highest in T1 followed by T2 and T3. The N chitala exhibited highest survival rate (96.66%) in T1 than T2 followed by T3 (88.89 %). The best FCR value (3.02±0.09) was recorded in treatment T1 with 35% protein contain feed. Relatively, highest benefits (138690±175.36 BDT/ha) were found from treatment T1 compared to other treatments. Similarly, the cost benefit ratio was highest in T1 (1:1.23) and lowest in T3 (0.95). Findings indicated that treatment T1 (35% protein containing feed) was found best in terms of growth, production and economics of N. chital for fingerling production in ponds. Res. Agric., Livest.

The semi-intensive culture of tilapia is particularly ideal in developing countries because it provides a wide variety of options in management and capital investments. A total of 1000 Genetically Modified Tilapia (GMT), Nile tilapia (Oreochromis niloticus) fry were stocked and reared in a concrete pond with a dimension of 1x1x5m for six months. The mean values of the water quality parameters during the rearing/experimental period were pH 7.25±0.31, temperature 25.85°C±2.98ºC; dissolve oxygen (DO) 4.166mg/L±0.55mg/L; Nitrate 9.44±1.91; Nitrite 40.99±1.38 and Ammonia 0.01. The fish specimens were fed twice a day (morning and evening) with coppens at three percent of their body weight and the parameters recorded were, 11.48 ± 5.4 8 MWG;177.6±122.9%MWG,204.6±19.2DRF:1.44±0.14WRF;6.14±0.57, MRF:0.67±0.38F CR:0.002±0.001 SGR, and 0.006±0.002 GEFC. The data indicated that mean weight gained (MWG) of Oreochromis niloticus increased gradually reaching its maximum. FCR values gradually decreased throughout the experiment which indicates that the lower the FCR the better it is for fish growth. The survival rates of the fish specimens during the experiment were 100 percent at different optimum temperatures, there was an increased trend in the growth with an increase in dietary protein level. It has been clearly verified from this experiment that all super male of Oreochromis niloticus grew better also in concrete pond. This result will promote the use of Genetically Modified Tilapia (GMT) in fish farming, because more weight are achieved and this will help to meet the goal of controlling tilapia prolific reproduction.

Abstract Appropriate irrigation water quality is essential for maintaining soil properties. This study investigates numerous physicochemical properties of irrigation water in three Himalayan valleys in northern Pakistan, receiving water from different sources. A total of 36 samples (3 replicates from four points at each site) were randomly collected and analyzed following standard laboratory techniques. The results revealed that most of the physicochemical parameters were within the permissible limits as specified by FAO, USEPA, and WWF for agriculture water. However, the total dissolved solids, potassium, mercury, nickel, and cadmium were found beyond the recommended ranges. Analysis of variance indicated that the mean values of various constituents differed significantly across the sources. Among the water sources, the mix of spring and glacial meltwater was found to contain maximum parameters within the permissible limits. The study recommends further investigating the implications of the existing water quality parameters on crop productivity and human health.
