Study on the ichthyofaunal diversity in relation to physicho-chemical characteristics of Tulsi Dam, Mandangad, Dist.-Ratnagiri, Maharashtra, India

Abstract

Tulsi dam is the freshwater reservoir located at Tulsi village of mandangad taluka in Konkan region. The study of physicochemical characteristics and ichthyofaunal diversity were carried out during January 2024 to December 2024. The physicochemical characters of water found suitable for drinking as well as fish culture. Till date the scientific data on ichthyofaunal diversity not carried out. So, it is attempted to make the study on ichthyofaunal diversity of this dam. For one year study, in the present study, 23 species of fresh water fishes were collected from Tulsi dam and distributed in 6 different order 12 families and 13 genera and presented in Table-2. Among this, Cyprinidae family was dominated with 11 fish species and contributed 48%, followed by Siluridae 1 species with 4%, Bagridae 4 species with 18%, Channidae 2 species with 9%, Gobidae 1 with 4%, Anabantidae 1 species with 4%, Chichlidae 2 species with 9%, and Mastacembelidae was 1 with 4% The data were obtained during study were discussed with recent literature and summerised in table 1 and 2.
