Fish samples were collected with water quality parameters from three sampling stations of the Bakraha River from October 2017 to June 2018 by using cast net, bamboo fish traps and mosquito nets. We collected nine species of Cypriniformes in two families: Cyprinidae with six species and Cobitidae with single species, and Perciformes in single family: Cobitidae with single species, and six genera. Order Cypriniformes constituted the highest species number 8 (88.88%) followed by Perciformes (11.12%).
The most common species of Bakraha River were Barilius bendelisis
, Barilius barila, Puntius sophore, puntius gonionotus
and Garra rupecula.
The highest diversity index (1.58) was recorded in January, and lowest diversity index (1.27) was recorded in April. Fish diversity of Bakraha River has been dwindled. It might be due to overexploitation, illegal electro-fishing, stupefied poison herbs, climate change, and sudden change of environmental variables.Pages: 267-271 | 1016 Views 72 DownloadsDownload Full Article:
