Ichthyotoxic effect of Phyllantus niruri leaf
Abstract

Phyllantus niruri is a versatile African medicinal plant employed for control of several human ailments. It has been reportedly used in control of certain fish infections. It lowers fish blood sugar level, has immunostimulant activities and is a stress reliever in fishes. The present work shows that despites its health benefits, it has some ichthyotoxic effect which is both concentration and time dependent. The affected fishes showed behavioral changes which include weakness, erratic swimming and moribund behavior and finally death. The gills of such fishes showed lamellae inflammation and distortion and serious gill shrinkage and lamellae erosion. They must have died due to poor supply of oxygen. The work therefore suggests that care should be taken when treating fishes with Phyllantus niruri in order not to exceed its safe limit.
Keywords: Phyllantus niruri, Clarias gariepinus, ichthyotoxicity, gill lamellae inflammation, lamellae erosion
