Quotas have proved to be ineffective, and lead to the counterproductive mountain of discards currently helping deplete our world's fish stocks for no use or economic gain to anyone. What is more effective is regulation of fishing effort, the 'days at sea' regulations aka 'tie-up rules'. ...

Imagine an in game purse seine! Needs a few ropes and a hundred odd bits of string, and a load of floats along the top, you row round ALL THE FISH with it, close it up ... and now I am stuck working out how to get the fish out of the net. And then there are no fish left for anyone else, just like IRL.
