A study was conducted to investigate the infestations of monogenetic trematodes of juvenile carps of Mymensingh region. A total of eight (8) farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated of Indian major carps - Catla (Catla catla), Rui (Labeo rohita) and Mrigal (Cirrhinus cirrhosus) during June, 2010 to May, 2012. Monthly samplings were carried out with 5 fishes of each species and each farm. Altogether 2880 fish host were examined of which 1424 hosts were found to be infested with monogenetic trematodes of which 626 from Govt. and 798 from Pvt. farms. The monogeneans were very common in gills of all fishes. Water quality parameters were taken and management practices were also noted. The risk of infestation by monogeneans of carp significantly (p<0.001) increased when the water quality parameters were deteriorated. Prevalence (%), mean intensity and abundance were found to be species specific and also varied with seasons and management systems practiced by different farmers. Prevalence (%) of monogeneans in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms. The prevalence (%) of monogeneans were significantly (p< 0.01) higher in rainy season than dry season. Mrigal was more infected by monogeneans followed by Catla and Rui.Res. Agric., Livest.

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.

Studies were conducted to investigate the infestations of Argulus of juvenile carps of Mymensingh region.  A total of 8 farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated Indian major carps - Catla (Catla catla), Rui (Labeo rohita) and Mrigal (Cirrhinus cirrhosus) during June, 2010 to May, 2012. Monthly samplings were carried out with 5 fish from each species and each farm. Altogether 2880 fish host were examined of which 940 hosts were found to be infested with Argulus during the study period. The Argulus were very common in body surface, base of the pelvic, pectoral, anal, caudal fin, muscle and mouth cavity of all fishes. Water quality and management practices were recorded in different farms. The risk of infestation by Argulus in carps significantly (p<0.001) increased when the water quality parameters were not maintained the optimum level. Prevalence (%), mean intensity and abundance were found to be species specific and also varied with seasons and management systems. Prevalence (%) of Argulus in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms. The   prevalence (%) of Argulus were significantly ( p< 0.01) higher in rainy season. Rui was more susceptible than Catla and Mrigal by Argulus.

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.

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.
