Maybe the proper solution is to increase the production? I found a much better article on bluefin tuna troubles in Scientific American - indeed there are attempts to farm tuna: http://www.sciam.com/article.cfm?id=bluefin-tuna-in-peril http://www.sciam.com/article.cfm?id=bluefin-tuna-in-peril BTW that's also one of the reasons why I think predicting populations 40 years in advance is hard. Even for a good model assumptions can change. And for systems of nonlinear differential equations even small differences in constants can lead to widely different outcomes.
