STUDY ON BIODIVERSITY, FEEDING AND GROWTH OF FISHES WITH REFERENCE TO PHYSICO- CHEMICAL PARAMETERS OF MAHANADI RIVER IN SHIVRINARAYAN DISTRICT- JANJGIR- CHAMPA CHHATTISGARH, INDIAPrakash Kumar Jaiswal, Peeyoosh Tiwari Jaiswal and K.R. SahuAbstract Mahanadi is longest river originating from Chhattisgarh, Mahanadi is also called Ganga and life line of Chhattisgarh, many animals are found in the water of Mahanadi river, fish is a major vertebrate animal found in the water of Mahanadi River which spends their entire life in water, hence the quality of water affects the life of fish and their various Biological activities. This investigation was carried out from March 2020 to February 2021 in selected study area. During the study period water samples were collected through sampling bottle and its physico-chemical properties were also analyzed as per following standard method given by APHA (2005), which show variation according to the season. The fish samples of river water were collected by using different types of nets like gill net, cast net and crafts, through the help of local fishermen, collected fishes were photographed and fixed into 10% formalin Solution. The collected fishes were identified with the help of standard books and keys, the feeding habit of river fishes were also studied by the observation of food substance found in their stomach, and to study the Growth of fishes we collected them at monthly intervals and measured their length and weight, during the entire study period a total number of 30 fish species were recorded on particular water parameter. Most of the Physico â chemical parameters analyzed in the Mahanadi river water at Shivrinarayan were in acceptable range. This study we come to know that the Mahanadi river water quality of Shivrinarayan area is suitable for biodiversity, feeding and growth of fishes. |
