Abstract

This study is aimed at assessing the fish species diversity in Gubi Reservoir, Bauchi state Nigeria. It was carried out for a period of six months (October 2017-Match 2018). Thirty-six thousand five hundred and sixty-six (36,566) fishes, comprising eight (8) species belonging to six families were examined from fishers using different fishing gears include gill net, cast net, hooks, burgi net and maley net.
