overfishing
1) Catching too much fish for the system to support leads to an Overall degradation to the system. Overfishing is a non-Sustainable use of the ocean.
Thepractice of commercial and non-commercial fishing whichis depletes the Fishery by catching So Many adult fish thatâ not enough Remain to breed and replenish the Population.Overfishing Exceed the Carrying Capacity of the Fishery.
Catching Too many fish; fishing so much thatâ the fish CAN NOT sustain Their Population. The fish get fewer and fewer,Until finally there are none to catch.
Fishing with a sufficiently high Intensity to reduce the Breeding stock levels to such an extent that theyâ will in the longersuppport sufficient Quantity of fish for sport or commercial harvest.
What is Causing overfishing
Worldwide, Fishing Fleet are two to three times as large as needed to takepresent day catch of fish and to other marine species and ocean whate Our dog sustainably support. On a global scale we have enough fishing Capacity 5 to cover at least fourEarth like planets. On top of the overcapacity Many fishing Methods are unsustainable in Their Own Way. These Methods Have a large impact on the basic functioning of OurMarine Ecosystem. These unselective fishing practices and gear cause Tremendous destruction on non-target species. Bycatch 6 / Discard 7 and bottom trawling destruction are twoexamples of this.
In the real world all this comes down to two serious problems:
*We are Losing species as well as Entire Ecosystem. The result *the Overall Ecologicalunity of Our Oceans are under stress and at Risk of collapse.
We are in Risk of Losing Valuable food source Many depend upon for social, Economical or Dietary Reasons.
