The fishing, either in fresh water or salt takes many forms. With networks of pull but how shows the world fisheries overview? What is the future of fishing in the world? In the next article will discuss issues such as over fishing, the Illegal and other destructive fishing methods that threaten the future of this practice.
Humanity has fished since the beginning of your story if it has been during the twentieth century when this practice has been extended to global by motorized craft, cooling the same, and so on.
This practice, like any other massive incursion of man, has its environmental consequences, And the specific case of fisheries there are certain practices that have clearly negative effects on our environment, for example:
Overfishing: Occurs when the level of fish drops below a level that would consider a standard because overfishing. It also has devastating effects on the ecosystem beyond the species in question and also affects the rest of marine animals.
Illegal: Fishing without a permit out of season, failing to capture the maximum quotas, fishing in closed areas or species that have not reached maturity allowed, and so on.
Destructive fishing methods: As happens with trawling, which often uses a non-selective capture species which in principle are not wanted, such as coral reefs, and ends up killing animals unnecessarily and attacking the biodiversity. Within this category we also find use of explosives and some kind of traps equally lethal with the blind and marine.
Polluting the ecosystem with the waste or escapes ships.
At present the Overfishing is reaching some levels that begin to compare with the shortage of oil because although unlike the latter, the fishing itself be considered a renewable resources constantly reaching maximum quotas, i.e. points where the ocean can no longer provide more.
The impact has been especially tough on slow-growing species, such as the Sharks. According to a study Boris Worm, To continue, all marine species that are caught have now collapsed (i.e., reduced their numbers dangerously) in mid-century, it seems we would be in the operating threshold and changes would be required to ensure the long term use. But what we found major problems?
To begin with, that demand will continue to increase, as the global human population does too. On the other hand, that fish farms are based on economic fundamentals rather than preserving the balance of ecosystem.
The solution, as in all operations of the natural resources passes through a responsible use of them and an incentive for sustainable fishing methods, Including, for example, capture modes that were not harmful to the environment that discussed preserve maximum biodiversity.
