In order to save and restore fish populations fishermen will loose their jobs. It is a terrible thought that a fishermen, with his years of experience and knowledge of the seas will be out of work. One proposed solution might be to recruit the out of work fishermen to the enforcement agency. This would allow them to use their superior knowledge of the sea to help enforce the laws, seek violators, and (if put in a scientific position) increase the fish populations. We must realize that fishermen will be out of work as we reduce the number of fish they are able to catch. From an economic standpoint we must try to reduce the economic impact our solutions will have. We must try to find places for any out of work fishermen that might result from our solution. Recruiting them into the enforcement agencies, scientific research teams, and other agencies that would benefit from their knowledge of the seas would both help the fishermen and reduce the economic impact that might result.
Twenty years ago the United Nations passed the "Law of the Sea." The Law of the Sea was intended to resolve the major oceanic problems experienced by countries. Problems such as territorial issues, fishing issues, environmental issues, pretty much anything relating to the seas. The Law of the Sea developed the 12 mile radius all countries have off of their shores. Within the 12 mile radius countries have absolute jurisdiction and power of what goes on their. There is a 200 mile economic zone where it is "for the use of
living and non-living natural resources."
The Law of the Sea made plenty of suggestions regarding increasing fish populations and preserving the natural habitat. The main problem is that they are all suggestions. The Law of the Sea offers no means of enforcement and does not state that countries should adopt the policies. It basically implies that it would be best if countries adopted them.
