Fish Stock Conservation
What is Fish Stock Conservation?
The management of a fished population so that it is not removed faster than reproduction replaces it. Closed seasons stop fishing while the fish are breeding so that spawning is not interrupted; protected areas provide places where fish can grow and reproduce with little or no harvesting; controlled net types and mesh sizes allow young fish to escape and reduce the catch of unwanted species; quotas limit the mass or number that may be landed; monitoring measures the size of the stock and the catch so that limits can be adjusted; and education increases understanding and compliance.
