- Purse Seine 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 is popular on India’s western coasts.
- 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 10 years.
- However, fishermen using traditional methods have placed the blame squarely on the rise in purse seine fishing.
Advantages of this method
- Purse-seine fishing in open water is generally considered to be an efficient form of fishing.
- It has no contact with the seabed and can have low levels of by catch.
- It can also be used to catch fish congregating around fish aggregating devices
- It is used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel.
- Purse seining is a non-selective fishing method that captures everything that it surrounds, including sea turtles and marine mammals.
