A majority of younger fish comprising the spawning stock is a function of Maximum Sustainable Yield management (MSY). This MSY management balances the numbers of larger spawning fish taken out of a stock against the numbers of individuals of smaller younger fish entering the stock or “recruitment”—guess what, this yields a highly unstable stock of smaller younger fish.
