Abstract

After the introduction of ring net in Kozhikode district in 1989, there was a gradual reduction of other traditional pelagic gears in this area. At present, ring net is the main gear for the exploitation of pelagic resources like oil sardine and mackerel. One of the problems faced by the fishermen operating the ring net is the damage of the gear caused by dolphin when it tries to prey up on the fish. Now the fishermen have found out an indigenous way to save the net from this menace by encircling the ring net by another net. This method has been in use by some boats for the last four to five years, and of late it has become very popular.
