Major biological processes that establish the year‐class strengths of Atlantic coast striped bass stocks (Morone saxatilis) are reviewed. Environmental factors seem to be the most important determinants of the initial population sizes. A general management strategy is proposed, which is consistent with the environmentally controlled occurrences of dominant year classes, and which also optimizes benefits from the fisheries. Because the relative importance of biological and abiotic population controls is uncertain, the proposed management strategy also strives to protect the reproductive potential of the striped bass stocks. This biologically based strategy can be implemented in the form of regulations that are flexible temporally and geographically.
