Regulations are not enough to stop over-fishing as it's almost impossible to get a worldwide regulation... Also, el niño years do not help the population of sardines (even though it slows over-fishing for them down a tremendous amount).
We need to save spiny and smooth dog fish (not even that closely related despite similar common names) from over-fishing too.
Worldwide regulation actually isn't necessary- the establishment of marine wildlife preserves generally does the trick. Fish populations restore rapidly inside them, then spread outwards from there. Plus, fishing bans in a specific area are pretty easy to enforce.
There are literally hundreds of species at risk from being overfished. 90% of all large bony fish by mass have been taken from the ocean in the last century. It's an extremely dire situation.
