Abstract: Macro invertebrates composition and physico-chemical characteristics of Garin Garba Stream Tumu, Gombe, Nigeria was investigated between April and June, 2019. Physical and chemical characteristics includes temperature, pH, Electrical conductivity, turbidity, depth and width and macro invertebrates were sampled fortnightly for a period of three months. It was recorded that physico-chemical characteristics of the four sampling stations shows no variation in all the sampling stations. Shannon Weiner index was employed to determine the abundance of macro invertebrates in each sampling station.
