Abstract

Several methods have been developed for increasing fish production; elimination of undesirable fish populations by using fish pesticides is the one method among them. The study has been conducted to replace the conventional pesticides by some herbal medicinal plant. The present experiment has been conducted to find out the effect of rotenone obtained from Surpunkha (Tephrosia purpurea) on climbing perch (Anabas testudineus). There are several plants available which are used as a source of fish poison rotenone. In the present study Surpunkha (Tephrosia purpurea) has been used as a source of rotenone. Tephrosia purpurea, commonly known as Surpunkha is a kind of herbal pesticide which can be used as a best substitute over other conventional pesticides for eliminating undesirable fishes because it is quite abundant in the subcontinent and the cheapest possible pest killer having the least hazard of pollution.
