Biodiversity study of SIS Small Indigenous Species of fish in Northwest part of Bangladesh and detection of threatened species

Abstract

This study provides the current status of small indigenous fish species especially the threatened species. Regular data were collected from some important urban and peri-urban fish markets and from natural waters of the Northwest part of Bangladesh. The availability of SIS of fish declined to a great extent over the years and many of them are rare or endangered. Due to high population growth there is an ever-increasing gap between supply and demand of SIS of fish. Some rivers of the Northwest part of Bangladesh are well connected with Indian rivers and that causes the SIS of fish diversity in the natural waters comparatively rich. The most significant message of this study is that, some vulnerable and endangered SIS of fish are locally abundant in the natural waters of the Northwest part of Bangladesh. So they should be conserved for their common availability and sustenance throughout the country that would be a most important step in favor of global ichthyo-biodiversity conservation
