Abstract:
Fish, a natural resource, has received great attention
from all over the world. since it provides a cheap protein,
employment and income to the millions of people for centuries.
So fishermen, industrialist and multinationals are trying to
exploit the marine resources to their maximum benefit by
using modern craft, advance fishing equipments and efficient
gear. Fishery resources in the open system particularly in
oceans, were considered to be unlimited. However, recent
developments in the innovation of efficient craft and gear
using well tested material fitted with modern equipments that
have greatly enhanced the mobility of craft, agility of gear
and the ability of equipments to locate fishery resources
have proved otherwise. Hence as the exploitation increases
with more effort entering the fishery, the catch per unit
of fishing effort starts to decline due to the limitness
of the resources. The heavy fishing pressure in the recent
past led to commercial extinction of a number of stocks such
as. the North Sea herring, California sardine, Japanese
Sardine and Peruvian anchovy (FAO. 1968: Gulland, 1974).
In India, seer fish from Palk-Bay declined due to uncontrolled
fishing (Devaraj 1983).
