China and Russia, are major over fishers. They have huge factory ships with swarms of smaller netters grabbing every fish they can. They do not respect size/species limits. Many countries have used armed patrol boats for offenders in their 200 mile economic zone. mid ocean sea mounts are have their fish exterminated by these vessels. Atlantic cod may not return because of over fishing on shallow banks that extend over 200 miles from Canada = where all fish are grabbed and the under 200 mile zone does not create enough young fish to compensate for these losses. Canada need to extend their control to the Grand Banks to add a contiguity zone. https://en.wikipedia.org/wiki/Grand_Banks_of_Newfoundland
