Overfishing in The World.

6. Overcapacity:
All over the world, many fishing industries
have huge vessels, equipment and
technology that they can deploy deep into
the oceans.
Unsustainable Fishing:
This involves using nets, fishing methods
and other equipment that catch too much
fish to a degree that they are endangered. It
also involves catching other sea animals
other than fish in the process.
Economic and Food Needs:
The amount of fishes that fishing industries
bring ashore depends on the market and
needs of consumers. In the past century,
humans have multiplied in many folds and
the need for food and fish has also
multiplied.

7. Ecosystems Destruction
According to marine ecologists,
unsustainable fishing is the greatest
threat to ocean ecosystems. The
practice destroys the physical
environments of marine life, and
distorts the entire food chain in the
oceans.
Economic Impact
Sustainable fishing ensures that
people’s livelihoods are protected and
the fishing business is sustained.
Overfishing does not guarantee that,
and soon, big investments will go
waste and people will be out of work.
Ghost Fishing
Many large fisheries stay for weeks
and months in deep seas and
sometime loose their nets. These
nets continue to trap and catch
fishes under the water and end up
killing them.
Pollution
Oil and liquid spills, chemical and
solid elements discharged into the
water by fishing boats, vessels and
trawlers often hurt marine life.

8. Safe catch limits
A constantly reassessed, scientifically
determined, limit on the total number of fish
caught and landed by a fishery. Politics and
short time economic incentives should have no
role in this.
Controls on by catch
The use of techniques or management rules to
prevent the unintentional killing and disposal of
fish, crustaceans and other oceanic life not part
of the target catch or landed.
Protection of pristine and important habitats
The key parts in ecosystems need full protection
from destructive fisheries; the spawning and
nursing grounds of fish, delicate sea floor,
unique unexplored habitats, and corals.
Monitoring and Enforcement
A monitoring system to make sure fishermen do
not land more than they are allowed to, do not
fish in closed areas and cheat as less as
possible. Strong monetary enforcement is
needed to make it uneconomic to cheat.
