Ban by coastal States on purse seine fishing not justified

In News
  • The Central Government has told the Supreme Court that a ban imposed by certain coastal States on purse seine fishing is not justified.
Purse Seine
  • Purse seines fishing is used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel.
  • A vertical net ‘curtain’ is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish.
  • Purse-seine fishing in open water is generally considered to be an efficient form of fishing. It has no contact with the seabed.
  • It can also be used to catch fish congregating around fish aggregating devices.
  • Purse seining is a non-selective fishing method that captures everything that it surrounds, including sea turtles and marine mammals.
  • Several States and Union Territories like Tamil Nadu, Kerala, Puducherry, Odisha, Dadra and Nagar Haveli and Daman and Diu Andaman and Nicobar Islands have prohibited Purse-seine fishing in their respective territorial waters of up to 12 nautical miles.
Concerns
  • In some States, it is linked to concerns about the decreasing stock of small, pelagic shoaling fish such as sardines, mackerel, anchovies and trevally on the western coasts.
  • The scientific community argues that climatic conditions, including the El Nino phenomenon, are responsible for the declining catch of such fish in the last ten years.
  • Fishermen using traditional methods have placed the blame squarely on the rise of purse seine fishing.
  • They fear a further fall in the availability of these small fish if the ban is lifted.
