Abstract

Due to importance of Oreochromis niloticus in Aquaculture in Nigeria and the importance of the liver and the gonads in fish, the gonadosomatic and hepatosomatic indexes were measured after exposing the fish to different concentrations of Gramoxone, Glyphosate, Butachlor and Atrazine for fourteen days. These herbicides were observed to produce atrophy in the two organs, liver and gonads. The herbicides are therefore likely going to hinder fish production in the area due to their influence in these important fish organs.
