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

Abstract: The objective of this work was to evaluate a recirculating aquaculture system using biological aerated filters in tanks for tambaqui (Colossoma macropomum) fingerlings farming, with two initial stocking densities (1.4 and 2.5 kg m-3). The biofilters had similar materials (media) and the same granulometric standards, but inverted orders of the media (classic and inverted). The following were monitored for 90 days: water quality; zootechnical, parasitological, and hematological parameters; and hematimetric indices. Water temperature, oxygen levels, pH, electrical conductivity, and dissolved solids concentration were compatible with tambaqui farming and did not differ between the different biofilters and densities. The ammonia and nitrite value was associated with the stocking densities and not with biofilter. The zootechnical and hematological parameters and the hematimetric indices evaluated were not influenced either by the type of biofilter or by the stocking densities. Ichthyophthirius multifiliis, Anacanthorus spathulatus, Notozothecium janauachensis, and Mymarothecium boegeri were the parasites found. The aerated, classical, and inverted biological filters have similar efficiency in maintaining water quality parameters for tambaqui fingerling farming.

A 60-day experiment was conducted to optimize fish and plant component ratio in a recirculating aquaponic system. Three different fish: plant component ratio of Rohu (Labeo rohita) spawn to Spinach (Spinacia oleracea) plant viz. T1 (40 spawn:10 plants), T2 (40 spawn:14 plants) and T3 (40 spawn:18 plants) were assigned as treatments. All the treatments were compared for fish growth, plant growth, and various water quality parameters were observed to determine the best component ratio which maintains better water quality and gives better growth. Among all the treatments, the higher growth rate of fish was observed in T2 (5.08±0.12) followed by treatment T3>T2>C. At the end, the total production of spinach in terms of weight was 508.10±8.89 g in T2 followed by treatments T3 and T1. Based on the results, the fish: plants component ratio of 40 spawn:14 plants can be recommended for production of rohu seed and spinach in recirculating aquaponic system

Aim: The present investigation was conducted to access the effect of salinity stress on growth performance, survival and biochemical parameters of Gibelion catla under different salinity conditions with an idea to assess the potentiality of this species in inland saline affected areas. Methodology: A 30-day-experiment was conducted in 1000 l (n=10) FRP tanks to study the effect of different salinity levels on the growth and biochemical parameters of catla species. A total of 120 fish (10.4 g) was randomly distributed into four treatments (0, 3, 6 and 9 ppt) with three replicates. The water quality parameters such as pH, temperature, nitrite, nitrate, ammonia, alkalinity and dissolved oxygen were recorded for each treatment on weekly basis, whereas fish sampling was carried out at 0th and 30th day of the experimental period to ascertain survival, weight gain, specific growth rate and feed conversion ratio of the fishes from each treatment. Results: The highest growth rate was found in control subsequently in 3 and 6 ppt and the survival rate was 96.67, 83.33, 76.67 and 0% against 0, 3, 6 and 9 ppt, respectively. The red blood cells (3.65×106 μl) and haemoglobin concentration, (8.17 gm dl-1) were also higher in control fish, followed by 3 and 6 ppt. However, white blood cells (24.40×106 μl) and glucose level (123.23 mg dl-1) were higher at 6 ppt, compared to control. Plasma protein level of fish at control (0 ppt salinity) was significantly higher than those of fish exposed to 3 and 6 ppt salinities. Interpretation: The present investigation revealed that an increase in salinity level had a significant impact on the growth and physiology of Gibelion catla. However, this species can be reared in low saline areas for some time which will not only help in the utilization of salt affected areas but will also help in the generation of employment and income.

Aquaponics is the combined culture of fish and plants in recirculating aquaculture systems, an ecologically sustainable horticultural production technique with long traditions. The objective of this study is to compare flood-and- drain, and the water crossflow system and examine the differences in the water quality, fish yield and plant growth parameters for Common carp (Cyprinus carpio) and basil (Ocimum basilicum). During the study, water quality parameters of two treatments were compared in temperatures, pH, EC and NO3¯N were significantly different (p <0.05). Leaf area of the basil plants grew to an average of 20.37 cm2 (± 9.02 cm2). The plants’ biomass production was significantly different (p< 0.05) in the two systems. The biomass production showed lower yield, 458.22 g (± 214.59 g) in the constant flow system that in the flood- and- drain system 692.9 g (± 175.82 g). Fish Growth parameters were better in constant flow system (FCR 5.48 g/g ± 0.19). However, the specific growth rate (SGR) demonstrated that fish grew faster in flood- and- drain system 1.38 %/day (± 0.29).

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.

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.
