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.

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

Indian major carps (IMCs), catla (Catla catla); rohu (Labeo rohita) and mrigal (Cirrhinus mrigala) were cultured at stocking densities of 20000 (T1), 35000 (T2) and 50000 (T3) fingerlings ha-1 for a period of 300 days in nine numbers of polythene lined ponds having an average water area of 150 m2. Stocking ratio of catla, rohu and mrigal were 4:3:3. Fishes were fed 35% protein diet twice daily. Water pH was maintained within the ideal range (6 - 9) by intermittent liming. Significantly lower (p<0.05) levels of dissolved oxygen and higher values of total ammonia- nitrogen were recorded at higher stocking densities compared to lower ones. Significantly higher (p<0.05) specific growth rate (SGR) and lower feed conversion ratio (FCR) were recorded in T1 compared to T2 and T3. However, maximum production was recorded in T3 followed by T2 and T1. Highest values of investment as well as income were recorded in T3 followed by T2 and T1. However, the maximum net return was obtained in T1 (`140147±7048) followed by T3 (` 133694±7931) and T2 (`101944±4857). Further, significantly higher (p<0.05) profitability (PI) was recorded in T1 (85.51%) compared to T2 (45.03%) and T3 (45.04%). The results clearly showed that profitability of the culture system could not be increased only by increasing stocking densities.

Serum immunoglobulins (Ig) of mrigal Cirrhinus mrigala (Hamilton 1822) immunised with bovine serum albumin (BSA), were purified by affinity chromatography using BSA-CL agarose column. The purified mrigal Ig (m-Ig) was characterised under reducing condition by Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) which revealed two bands of 85 and 26 kDa corresponding to heavy and light chain, respectively. Following fusion of splenocytes from Balb/c mice immunised with purified m-Ig with myeloma cells, three hybridomas showing reactivity with m-Ig were cloned by limiting dilution. The monoclonal antibodies (MAbs) generated by these clones were designated as 3B2-E12, 3B2-F9 and 4C3-B2 and characterised by western blotting and isotyping. Western blot analysis of the supernatant from the three clones with purified m-Ig indicated that, all the three MAbs were specific to heavy chain. Isotyping revealed that 3B2-E12 MAb was of IgG1 isotype whereas the other two MAbs were of IgG2a isotype. Cross reactivity of anti-mrigal Ig MAb (3B2-E12) was observed with serum Ig of Catla catla and Labeo rohita indicating semi-conserved nature of Ig in Indian major carps.

The study was conducted to assess the growth and survival of <em>Macrobrachium rosenbergii</em> in earthen culture ponds in order to know about the growth potential of <em>M. rosenbergii</em> in mono as well as polyculture conditions in Jammu. Polyculture experiments of prawn with some selected carps Indian Major Carps (<em>Cirrhinus mrigala</em> and <em>Labeo rohita</em>) and Exotic Carps (<em>Cyprinus carpio</em>) were undertaken in 3 freshwater ponds for duration of 4 months. Under the monoculture conditions, prawns attained an average size of 10.40 ± 0.17 cm weighing 23.84 ± 0.32 g in 4 months and the survival rate was found to be more than 75%. The growth rate of prawns was found to increase steadily during the first half (upto mid-October) after which a decline in the growth rate was evident as the mean temperature reached below 18°C. In the polyculture ponds the prawns attained an average size of 10.10 ± 0.03 cm weighing 18.39 ± 0.89g (without<em> C. carpio</em>) and 8.4 ± 0.36 cm weighing 15.23 ± 0.36 g (with <em>C. carpio</em>) in 4 months and their survival rate was less than 70%. Prawns being benthic feeders utilized the leftover food (of the fishes) that settled at the bottom, therefore, saving the feed cost. It was observed that mean size of the fish attained in the polyculture practice was almost similar to that obtained in the monoculture. The ideal prawn polyculture should be practiced with fast growing compatible carps such as Rohu and grass carp. Bottom feeder carps such as Mrigal (<em>C. mrigala</em>) should be avoided in prawn polyculture practice as they compete with prawns in feeding.

Halda is a unique resourceful tidal river of Bangladesh, where Indian major carps (Catla catla, Labeo rohita, Cirhinnus mrigala, and Labeo calbasu) spawn from April to June. Ecological conditions are auspicious from time immemorial which serves as a natural breeding ground in the world. The present study was conducted over the period of January-June 2017 to identify the main species of Zooplankton fauna and also fi nd out the dominancy of the highest plankton groups in the lower Halda River. A total of 3 major zooplankton groups-Copepoda, Rotifera and Cladocera were identifi ed during the six months period. A total of 35 species under 4 family showing the dominancy for the class Rotifera consisting of 7 genera were recorded from fi ve sampling sites. The lowest group was Cladocera consisting of 5 genera. The composition and dominance of the zooplankton community among fi ve different sites in the lower Halda River showed some close inter-relationships. The present study suggests for conducting further research to know the overall conditions and to make a complete list of available zooplankton fauna that exert impact on the water quality of the Halda River.

Labeo calbasu is a freshwater fish species and is the most important carp species next to three Indian Major Carps Labeo rohita, Catla catla and Cirrhinus mrigala. It is a popular food fish and also is admired as a sport fish. Recently this fish species has also made its entry in ornamental fish markets of India and abroad. In last few years, the natural populations of this fish species has seriously declined due to over fishing and other anthropological reasons. In India it has been reported as Lower Risk near Threatened and in Bangladesh as endangered species. Earlier number of works has been conducted on different aspects of Labeo calbasu including food and feeding habit and reproductive biology. This report has been prepared with a view to sum up all those previously documented information along with pointing out the missing information further study of which will be beneficial for its fishery. Apart from this, it has been tried to note down some possible measures which should be considered for its conservation.
