| 内容記述 | The catch of Spanish mackerel in the Harima-Nada, the main fishing area in the eastern Seto Inland Sea, was at its maximum in 1987. This level was reduced to half in 1990. On the contrary, the catch off Gobo within the wintering area decreased to around one third of the level in 1987 compared to that prior to 1984. Total mortality coefficient of the stock was estimated as 0.75 from the averaged catch curve for the period 1987 through to 1990. Natural mortality coefficient was determined to be 0.31 based on the life span, and the fishing mortality coefficient (F) was 0.44. F0.1 was estimated as 0.27 using the yield per recruit analysis. The stock seemes be over-exploited (growth overfishing). If fishing is ceased in autumn and fishing effort reduced at the F0.l level, the annual catch would increase by 6% and the total fecundity of the stock would increase to 40% level compared to that of an unexploited population. | |||||
