	The plot that my simulation made for the decline of herring from 1947 till the seventies is similar to the one published by the Government of the Netherlands. We conclude that a prohibition on catching herring in the seventies was necessary, otherwise herring would be extinct in the eighties. Permitting fishing on herring in the eighties without decent measurements wasn’t very tactic, because after 6 years the population shrunk again very fast. This was a wake-up call for the government to intervene and since the middle of the nineties, the population of herring grew again. Every year, the percentage of TAC is calculated, and in 2017 this resolved in a population of 2000 million kg of herring in the North Sea, with a TAC of 25%. We simulated if we keep this percentage, the population won’t be in danger ever again and we can keep catching herring. If we exceed this percentage, the number of catched fish will be greater than the number of fish, which means we will be obligated to stop fishing for a couple of years till the population is restored again. If we want that the catched fish don’t exceed the population, we set our TAC on 33% if we have the assumptions of 2017, with a starting population of 2000 million kg.
