Why doesn't anyone listen to the commercial fisherman, it is their lifeline of these people.?

Question

Commercial fisherman in small boats know what is going on in the ocean, why would they over fish it would mean no fish for years to come. They are more pollitacaly correct with their direction because they fear they will be put out of business in years to come. They have invested their live and financial backing to keep this industry going,

Answer 1

It's not the small fishermen who are depleting the oceans, it's the big factory ships from Japan and Russia that go out and scoop up every living thing in their nets for hundreds of miles. (Japan and Russia are the only countries I know of that do this, however there might be others.) it is they who are putting all fishermen out of business.
