This study describes the diets and feeding habits of Cyprinus carpio in integrated rice-fish farming system in the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, Central Bangladesh during May 1999 to August 1999. Percentage of frequency of occurrence and percentage in number methods were applied for the qualitative and quantitative estimation of plankton. The water quality parameters recorded during the study were within the suitable range for optimal fish growth and plankton populations were also abundant in the water of the rice plots. The phytoplankton population recorded from the gut contents of C. carpio was under 4 groups (viz., Chlorophyceae, Euglenophyceae, Cyanophyceae, Bacillariophyceae) and the zooplankton under 3 groups (viz., Rotifera, Cladocera, Copepoda). Bacillariophyceae and Chlorophyceae were the dominant phytoplankton group while Rotifera was the dominant zooplankton group in the gut contents of C. carpio. This study also revealed that, gut contents of C. carpio was composed of 48.47% phytoplankton and 51.53% zooplankton indicating omnivorous nature of the fish. The availability of plankton population in the rice plots and the food and feeding habits of C. carpio suggest that, this fish could be a vital candidate for integrated rice-fish aquaculture.

The present investigation was conducted in the Agronomy field laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh during May 1999 to August 1999 to reveal the food and feeding habits of Amblypharyngodon mola in the rice field ecosystem. Percentage of frequency of occurrence and percentage in number methods were used for the qualitative and quantitative estimation of plankton population. Results showed that, during the present study, the water quality parameters were within the suitable range for optimal fish growth and plankton population was abundant in the water of the rice plots. Gut content analysis of A. mola revealed a sum of 32 genera of phytoplankton belonging to Chlorophyceae (17), Euglenophyceae (2), Cyanophyceae (7) and Bacillariophyceae (6) and 8 genera of zooplankton under Rotifera (3), Cladocera (2) and Copepoda (3). In general, Navicula, Fragilaria, Chlorella, Chrysococcus, Closterium, Oscillatoria and Gomphosphaeria were found abundant both in the water of the rice plots and in the gut contents of A. mola indicating that, these genera are preferred food of this fish in the rice field ecosystem. Gut content analysis also exposed that, phytoplankton was the major food item constituting 94.38% of the gut contents’ composition of A. mola whereas zooplankton comprised only 5.62%. The results of this study conclude that, the A. mola is planktivorous in nature, feeding mostly on phytoplankton and could be a suitable species for integrated rice-fish farming.DOI: http://dx.doi.org/10.3126/on.v11i1.8245 Our Nature Vol.11(1) 2013: 61-75

Aquaponic model is a farming system that integrates a recirculating aquaculture system with hydroponics. There are three hydroponic methods commonly employed in the aquaponics systems: the media bed (MB), the nutrient film technique (NFT) and the deep-water culture - floating rafts (DWC). This study was conducted to evaluate effects of two hydroponic systems (DWC and MB) on water quality parameters, growth rate of fish and development of vegetable in the aquaponic model of snakehead fish (Channa striata) and leaf mustard (Brassica juncea). Snakehead fish were stocked with a density of 40 fish/75 liters of water and were cultured for 167 days. The results showed that daily temperature, pH and dissolved oxygen parameters in the two systems were almost the same and relatively stable while the electrical conductivity in the MB was much higher than that in the DWC. Similarly, the levels of the parameters weekly monitored (ammonia, nitrite, nitrate, total phosphorus, and alkalinity) in the MB were higher than those in the DWC. At the end of the experiment, final weight, weight gain, specific growth rate and survival rate of fish in the MB treatment were higher than those in the DWC treatment, but the feed conversion rate of fish in the MB was lower than that in the DWC. On the contrary, vegetable yields in the DWC were significantly higher than those in the MB. In general, the DWC aquaponics work better than the MB system

Tarahara Fish Farm includes 37 large ponds as a fish super zone. Physicochemical parameters viz., air and water temperature, pH, DO, BOD, CO2, Cl-, TA and TH of these ponds were studied for two years (Nov. 2008 to Oct. 2010). The air temperature had positive and significant correlation with water temperature (r=0.893, P<0.01) but inverse and significant correlation with DO (r = - 0.669 P<0.05) and TH (r = - 0.673, P<0.05). Both air and water temperature showed a decreasing trend during the winter months of November to January and again September to October in both years. Similarly, positive and significant correlation showed by pH with DO (r =0.660, P<0.05) and BOD (r =0.846, P<0.05); by free CO2 with DO (r=0.854, P<0.01), chloride (r=0.648, P<0.05) and TA (r=0.616, P<0.05); by DO with TA (r =0.715, P<0.01) and chloride (r =0.625, P<0.05) and by TH with TA (r= 0.592, P<0.05) but inverse and significant correlation showed by pH with water temperature (r =-0.671, P<0.05); by free CO2 with BOD (r=-0.627, P<0.05) and by DO with BOD (r = -0.810, P <0.01). The water quality parameters were within suitable range for the fish growth and breeding with small fluctuations in different months during the first and second years. Physico-chemical parameters significantly (P<0.01; 0.05) differed between different months. However, no mass mortality of fish was recorded from this site. So, the area selected as fish super zone is fruitful to meet the expected production level of fishes and fish seeds in peripheral areas.

This research aimed to determine the stocking density that support the best growth and survival rate of carp cultivated in aquaponic systems, and to study the water quality of carp culture with different stocking densities in aquaponic systems. The study used 12 aquaria measuring 40x40x40 cm each (water volume of 50 liters). The experimental fish are carp (Cyprinus carpio) weighing in average of 3.5 g/individual.  The fish were cultivated with different stocking densities as treatment, including A = 4; B = 7; C = 10 and D = 13 individuals/aquarium.  The fish were fed with pellet at 5%/body weight/day with a feeding frequency of two times a day. The study was conducted for 4 weeks. Data consisting of daily growth, survival and water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite and nitrate) were measured once a week. The data obtained were analyzed by ANOVA. The results of the study showed that the difference in stocking density had no significant effect on the growth and survival of carp.  Water quality was in a reasonable range to support the growth and survival of carp cultivated with aquaponic systems.Keywords: cultivation, carp, aquaponics, stocking density, growth

The heamatological profile of two freshwater fishes Labeo rohita (Rohu) and Channa striatus (Murrel) with a relationship to the sex and the water quality under natural habitat was analyzed. The freshwater fishes were collected from the pond located in Thodaneri, Vadipatti taluk, Madurai district, Tamil Nadu, India. In heamatology studies, no significant variation was observed in Heamoglobin content and found almost the same in both the fish irrespective of the sex and also falls in the range of control value. In differential Leucocyte count (DLC) the following blood components Lymphocyte, Eosinophil, and Monocyte count were significantly higher than the control values and the values are found maximum in Rohu when compared to Murrel.RBC (Erythrocyte) count was almost the same in both the fish and the value falls between the range of control value Packed Cell Volume (PCV) count was almost the same in both the fish and the value falls between the range of control value. The values of Hb and PCV were found higher in male fish as compared to female fish. The leucocyte count is also higher in the males when compared to the females of both Rohu and Murrel. These may be also influenced by physiological activity, feeding habits, infectious agents, water quality parameters, and the environmental stress on the organism.
