On optimum size limit for the Gulf of Gdańsk flounder stock

[摘要] The protective size limit of flounder Platichthys flesus L. at the present exploitation level (F = 0.40) was estimated by means of two methods: the Beverton and Holt on the one hand and the Goh on the other. Regardless of the procedure used, it was found advisable to increase the present protective size limit (21.0 cm). In the author′s opinion, the Goh method assuming a limited fishing season yields more reliable results. The author proposes to increase the flounder protective size limit from 21.0 to 24.0 cm.
