The present investigation deals with the prevalence of infection of cestode, Pseudoinverta oraiensis19 parasitizing Clarias batrachus from Bundelkhand Region (U.P.) India. The studies were recorded from different sampling stations of Bundelkhand region of Uttar Pradesh. For this study 360 fresh water fish, Clarias batrachus were examined. The incidence of infection, monsoon season (17.50%) followed by winter season (20.00%) whereas high in summer season (30.00%).

The present investigation deals with the prevalence of three cestode parasites viz. Lytocestus sp., Proteocephalus sp. and Gangesia sp. collected from the intestine of a freshwater fish Channa punctatus in different blocks of Meerut region (U.P.) India during June, 2014 to May, 2015. A total of 125 parasites were collected throughout theyear. The high incidence of infection of all these species Lytocestus sp., Proteocephalus sp., Gangesia sp. was recorded in summer season (70.83%, 77.27% abd 72 % respectively) followed by winter season (63.63%, 57.89% abd 52.38% respectively) whereas infection was low in monsoon season (36.84%, 27.78% abd 23.52% respectively). The present study clearly indicates that the intensity of infection throughout the year was found highest in summer season followed by winter and lowest in monsoon. Findings show that beginning of the breeding period, feeding habitat, presence of intermediate host and environmental factors are influencing the seasonality of cestode parasitic infection.

Present paper deals with study of cestode parasites of genus Circumoncobothrium from fresh water fish Clarius batracus at Savitri river, (Dapoli) for the percentages of infection occurance during summer season,minimum during winter and tolarate during rainy season.The parasite mainly infected the intestine of host and fed on nutrients from digested food. It completed its life cycle in the intestine of host. By camparing different characters of it to identify that the species is new

The aim of the study was to determine the effect of Sago effluent on the levels of growth hormone in the blood samples of the fresh water fish Clarias batrachus. The fish were exposed to control and different concentrations of treated sago effluents. The concentrations chosen were 25%, 50% and 75% of treated sago effluent. The levels of the growth hormone were increased in the blood sample of the experimental fish Clarias batrachus, when compared with that of controls.

The fresh-water fish Wallago attu (Bloch. And Schn.) was collected from local fish market of district Balrampur (U.P.) and examined 15 specimens, of which only one specimen was found infected with 17 specimens of said species. The site of infection being the gill filaments of the host. The present form differs from S. devraji, S. malabaricus and S.parvulus in having accessory pieces on dorsal anchors and presence of wings on dorsal anchors. Moreover, it differs from S. indicus, S octolytus, S. aori and S. sudhakari in having cephalic glands and different shape of copulatory complex and vagina. On subsequent study, the present form appear to be a new species of the genus Silurodescoides Gussev, 1974 and described as a new species and named Silurodescoides srivastavai n. sp. in the honor of Dr. C.B. Srivastava, Ex. Dy. Director, Zoological Survey of India, Kolkata.
