Summary This short paper presents an optimal control model for cost‐effective and ecologically conscious management of released fish. Finding an optimal management strategy reduces to solving a Hamilton‐Jacobi‐Bellman equation having a solution by separation of variables. This paper analyzes the behavior of the solution and the associated optimal management strategy. The latter is verified with an actual strategy for Plecoglossus altivelis in Japan.
