ABSTRACT
During the study period it was observed that few fishes were infected from the collected fishes, total 620 fishes were collected, mold (Cyprinus carpio) Silver carp (Hypophthalmichths molitrix) 62 Morakhi (Cirhinus madrigals) 62 Thalla (Catla Catla) 62 and Rohu (Labia Rohita) 62 fishes were collected. The rate of infestation was higher in the summer season while rate of infestation was lower in the winter season, the rate of infestation is higher in the month of July 23% while lower in the month of February 06%, also in summer season when water is less present in the lakes the fishes are close to eachother then parasites spread easily, while in winter season when the more water is present in the lakes the space between fishes are more than no more parasites are spread. When the temperature in summer season rises at this time the reproduction and development of parasites become rapid hence rate of infestation increases, while in winter season when temperature falls the reproduction of female parasites restricts, hence rate of infestation decreases. Rate of infestation increase with the increasing of temperature .Also in the summer season hardness of water increases and acidity of water increases, b while in winter season the hardness Decreases and base increases. The rate of infestation was higher in the summer season while rate of infestation was lower in the winter season, the rate of infestation is higher in the month of July 23% while lower in the month of February 06%, also in summer season when water is less present in the lakes the fishes are close to each other then parasites spread easily, while in winter season when the more water is pr The total infestation percentage of parasites are Argulus 30%, Lernaea 20%, Trichodnina 20% and Chilodonella 15% and the parasites attack on the fishes Glulfam 20%, Silver carp 16% , Morakhi 11% , Thallah 5% and Rohu 4%. Infested in the lakes the space between fishes are more than no more parasites are spread.
