The Chinese fishing nets at Kochi are used for a unique method of fishing. Operated from shore the nets are extended on bamboo poles and held up by huge mechanical strctures which are lowered and raised from the sea. They are counter weighed by large stones. Each net is operated by a team of some five or six fishermen. The net is left in the water for only a short time; just a few minutes before it is raised back up by tugging ropes. The Chinese Fishing Nets of Cochin are said to have their origin in China.
