The major source of carp seed in India is from induced breeding and most seed farms in Karnataka State use ovaprim for commercial production of fish fry. The present study was conducted to investigate the possibility of employing a combination of buserelin (an analogue of mammalian LHRH) and domperidone (a dopamine antagonist) for the induced spawning of the three Indian major carps, viz. catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala). All the three species could be successfully induced bred using a combination of mLHRH-a and domperidone (DOM) through a single injection. Important aspects of induced spawning such as breeding response, fecundity, latent period, fertilization rate and quantity of spawn obtained with mLHRH-a +DOM were compared with those of sGnRH-a and DOM combination (ovaprim), a widely used fish spawning agent in India. The breeding response of females of all the three species treated with mLHRHa+DOM was 100%, while it varied between 86 and 100% for sGnRH-a+DOM treated fish. The fecundity, fertilization rate and quantity of three-day-old spawn realized for the former combination were equal or better than those obtained for the latter. Among the different doses tested, 0.8, 0.7-0.8 and 0.7 mlxkg-1 body weight (b.w.) of female produced consistently good results in catla, rohu and mrigal, respectively. Lower doses (0.4-0.5 mlxkg-1 b.w.) also led to the mass spawning of mrigal, with fertilization rate ranging between 89 and 93%. In all the trials, the males received either sGnRH-a+DOM at 0.1-0.2 mlxkg-1 b.w. or mLHRH-a+DOM at one-third of the dose given to the female. The quality of carp seed produced through mLHRH-a+DOM was good and comparable to that obtained with sGnRH-a+DOM and it is more economical than the former spawning agent.

Major Carps

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.

The effects of different ova diameters on hatching, growth and survival of fry of the common carp (Cyprinus carpio var. communis, Cyprinidae) and Indian major carps viz.Catla catla, Labeo rohita, Cirrhinus mrigala (Cyprinidae) were examined. The four female brooders of different weight and size of each of Cyprinus carpio var. communis, Catla catla; Labeo rohita and Cirrhinus mrigala were collected. The highest mean ova diameter was observed in (Cyc 4) 1.235 ± 0.006 mm, (Cc 4) 5.386 ± 0.098 mm, (Lr 4) 4.94 ± 0.167 mm and (Cm 4) 4.95 ± 0.091 mm; highest fertilization rate (Cyc 4) 92.48%, (Cc 4) 85.42%, (Lr 4) 89.64%, (Cm 4) 86.49%; highest hatching percentage (Cyc 4) 82.32%, (Cc 4) 79.67%, (Lr 4) 81.28%, (Cm 4) 80.17% and highest survival (Cyc 4) 75.57%, (Cc 4) 76.36%, (Lr 4) 80.51%, (Cm 4) 68.35% respectively. The specific growth rate was also found highest in Cyprinus carpio var. communis (Cyc 4) 5.94%, Catla catla (Cc 4) 5.62%, Labeo rohita (Lr 4) 5.81% and Cirrhinus mrigala (Cm 4) 5.86% in fry of brooders having maximum weight. The direct relationship of ova diameter to fertilization rate, hatching, survival percentage and the specific growth rate of Cyprinus carpio var. communis, Catla catla, Labeo rohita and Cirrhinus mrigala were recorded. However, after the fifth week, the growth rate of spawn reduced in all the groups and was least at the end of the eighth week.

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.

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.

In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur- a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel.Asian J. Med. Biol.

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.
