抄録

This paper proposes a method for the introduction of the fishery regulation preventing the temporal reduction of catch due to the introduction. The method uses the estimates of stock abundance just before annual fishing season and introduces a new level of fishing effort or age at the first catch in the year in which the catch level is projected to increase above the recent average of the catch. Simulation studies showed that the method reduced the risk of the temporal reduction if the number of recruits in the stock is not declining, but they also indicated that the recoveries of the stock are slow. Notes in application are given and the modification of the method is discussed.
