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).

An investigation was made on the ecto-parasitism of juvenile carps of Mymensingh region.  Eight  farms, four Government (Govt.) and four Private (Pvt.) fish farms were investigated for Indian major carps(Catla catla, Labeo rohita and Cirrhinus cirrhosus)  (Catla, Rui and Mrigal)  during  June, 2010 to May, 2012. Monthly samplings were carried out with 5 fish from each species and each farms. Altogether 2880 fish hosts were examined of which 1674 were found to be infested with different groups of parasites during the study period. The ectoparasites were very common in gill, skin, mouth cavity, muscle, base of the pelvic, pectoral, anal, caudal fin and body surface of all fishes. Eleven species of protozoan, thirteen species of  monogeneans and two species of argulus were recorded. The risk of being infestation by parasites in carps 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 ecto-parasites in carps was significantly (p< 0.001) higher in Pvt. farm than that of Govt. farms and was significantly (p< 0.01) higher in rainy season. Rui was more susceptible than Catla and Mrigal.

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.

Fish ponds operate as an open ecological system where natural and technological processes are built on one another and are implemented in a non-separable way. Pond fish farms contribute to preserve biodiversity. In both districts the composite fish culture technology is commonly followed for fish farming with six species combination i.e. Indian Major Carps (IMC) i.e. Catla, Rohu and Mrigal (Nain) and Exotic Major Carps (EMC) i.e. Silver carp, Grass carp and Common carp. There are 14 blocks in Basti district in which 3848 number of ponds are found. These ponds cover 1040.42 ha of water spread area. There are 16 blocks in Gonda district. The number of ponds is 4471 with water spread area of 3706.86 ha. The total productions of fishes are 1800 ton/year in Basti district while 3850 ton/year in Gonda district. The average productions are 2800 kg/ha/ year and 3000 kg/ha/year in Basti and Gonda districts, respectively. The data indicated that the Gonda district have more potential in fish production compared to Basti district. The maximum ponds were of less than 1 hectare in both districts. The respondents were 68% in Basti district and 76% in Gonda District. 82% and 70% respondents have leased pond in Basti and Gonda districts, respectively. Gonda district has more potential for fishing in future.

The uproar in antimicrobial resistance (AMR) among the aquacultured environment has led to the isolation of multiple antibiotic-resistant (MAR) Aeromonas strains. The current study aimed at the enumeration of antibiotic-resistant Aeromonas in carps of aquacultured environment and market samples. Isolation of Aeromonas was also done in Rimler-Shotts agar supplemented with novobiocin followed by antibiotic-sensitivity assay against 12 broad-spectrum antibiotics. Five oxytetracycline-resistant strains were examined for the presence of three tetracycline-resistant genes (tetA, tetC and tetE). The presumptive Aeromonas counts on starch-ampicillin agar were determined as log 3.00-log 6.45/g in carps, log 3.00l-log 5.06/ml in pond water and log 3.30–log 5.14/g in pond sediment. Higher proportions of motile aeromonads from market carps were resistant to chloramphenicol, cefalexin, gentamycin, oxytetracycline and trimethoprim than the farmed carps. Aeromonas strains depicted 57 resistant profiles. About 88.43% of the Aeromonas strains were of the MAR group among which 12.15% and 4.67% were resistant to ≥6 and ≥7 antibiotic groups, respectively. Selected oxytetracycline-resistant strains were negative for targeted genes. The current study implied the high prevalence of AMR bacteria in cultured carps in West Bengal, India. Furthermore, the study indicated that motile aeromonads comprise an effective marker for monitoring AMR in freshwater aquatic environments.

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.
