The study was carried out to find the prevalence of ectoparasites in carp species specifically Indian Major Carps (IMC) during the post monsoon season (November’16 to March’17). Four groups of ectoparasites viz. myxozoan, ciliophoran, monogenean and crustacean were recorded from a total 500 number of  carp species like, Labeo rohita, Catla catla, Cirrhinus mrigala and Labeo calbasu collected from different ponds of selected blocks of South 24-Parganas district of West Bengal. The highest prevalence (64.8%) of infestation had been recorded by Myxozoans and the lowest was by Monogeneans (4.8%). The highest and lowest ectoparasitic prevalence in carp was observed in L. rohita (32.9%) and C. catla (27.3%). Beside these, lower temperature (Average 19.3oC), low pH (Average 6.9) and marginal level of dissolved oxygen (Average 6.0ppm) were also created an unfavorable condition for parasitic infestation during this season. At the end of this experiment it was concluded that disease occurrences due to ectoparasites was high in winter with some key factors like temperature, pH and dissolved oxygen (DO).

The study was carried out to find the prevalence of ectoparasites in carp species specifically Indian Major Carps (IMC) during the post monsoon season (November’16 to March’17). Four groups of ectoparasites viz. myxozoan, ciliophoran, monogenean and crustacean were recorded from approximately 500 number of  carp species like, Labeo rohita, Catla catla, Cirrhinus mrigala and Labeo calbasu collected from different ponds of selected blocks of South 24 Parganas district of West Bengal. The highest prevalence (64.76%) of infestation had been recorded by Myxozoans and the lowest was by Monogeneans (4.79%). The highest and lowest ectoparasitic prevalence in carp was observed in L. rohita (32.88%) and C. catla (27.28%). At the end of this experiment it was concluded that sudden changes in water quality parameters, over stocking, lack of management practices and some other aspects were the key factors for disease occurrences in this post monsoon season.

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 present study attempts has been made to document the fishing crafts and gears which operated in Thirumoorthy reservoir, Tamil Nadu. This investigation revealed, the post monsoon season had higher catch per unit effort of 11kg/boat/day by gillnet fishing and about 20 to 30kg/day in cast net. Catla catla has the dominant fish species and accounted about 58% followed by Cirrhinus mrigala (29%), Labeo rohita (12%) and Cyprinus carpio (2%) against the total landings. However, three species including the Tilapia, Rohu and Mrigala were found to constitute fishery in the cast net with mean CPUE of 20 to 30 kg per day.

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.

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.
