STUDY ON BIODIVERSITY, FEEDING HABIT AND GROWTH OF FISHES WITH REFERENCE TO PHYSICO – CHEMICAL PARAMETERS IN MAHANADI RIVER OF SURAJGARH, DISTRICT -RAIGARH, C.G., INDIAPrakash Kumar Jaiswal, Peeyoosh Tiwari Jaiswal and K.R. SahuAbstract The variety and variability of plants, animals and microorganisms with an ecosystem is known as Biodiversity and in the aquatic ecosystem the study of aquatic biodiversity is done, aquatic ecosystem is the biggest ecosystem of the world. Water is the major component of all types of aquatic ecosystem. The quality of the water is directly or indirectly affected to the life of aquatic organism in present study has been carried out from April 2020 to March 2020 during the period of investigation water and fish samples were collected from different sampling sites in the Mahanadi River of Surjgarh area. The river water sample were collected by the help of sampling bottle and fish samples were collected by the help of local fishermen with uses of different types of Nets and crafts. The physicochemical parameters of the river water was analyzed which showed seasonal variation. The feeding habit of river fishes were also studied by the examination of food substance found in their stomach on the basis of feeding habit collected fish have been divided in to three categories like herbivore, carnivore, and omnivore. All these three feeding type may further grouped under three sub categories via-surface feeders, sub surface and column feeders and bottom column feeders. During the entire study period, a total 26 fish species have been identified and recorded on particular water parameter. The physic-chemical data of Mahanadi River that we have received from this study suggested that the water quality of Mahanadi River is suitable for the biodiversity of fishes. |
