    Abstract

    The mortality rates of N. japonicus are estimated from annual age composition of fish caught by trawlers. The estimated values are Z = 1.86, F = 0.72 and M = 1.14. The exidoitatlon rate (U) is estimated at 0.33 and the total annual stock at 1181 tonnes. The yield curve shows that the fishing mortality can be increased from the present level of 0.72 to 1.75 to get increased yield.
