Herbal Piscicides in Inland Aquaculture-A Review

Eradication of predatory and weed fishes is one of the most important steps in pre-stocking management of pond based aquaculture. The chemical piscicides are mostly pesticides of diverse nature, designed for land based agricultural practices. In the aquatic environment in fish culture ponds, besides acting as piscicides, they are bound to impact the environment negatively because of their long persistency and non-target oriented in action. Consequent to this, a number of plants derived, low cost and locally available materials became popular as piscicides particularly in the moderately intensive inland aquaculture all over the globe. The present paper reviewed a brief account of the herbal piscicides with particular reference to Indian aquaculture.
