Namboodiri, K.S. | Varghese, M.D.
Prior to stocking economic species in tanks and nursery ponds, all the unwanted and predatory fishes in them will have to be removed. Even though most of them can be caught with ordinary gear such as cast net, drag net, scoop net etc. Total or absolute eradication is not possible and those left over are sufficient to destroy all the fingerlings introduced. Development of an electrical method for killing predatory fishes at reasonable cost is therefore, expected to provide a solution. This paper deals with a few methods, based on the use of electricity and which are suitable for different ponds.
