Length-weight relationship and weight at age of chub mackerel Scomber japonicus caught in the northwestern Pacific Ocean by China, Japan, and Russia
Length-weight data of chub mackerels caught by China and eastern/western Japan are compared and parameters of length-weight relationship are estimated. The relationship among regions exhibits similar trajectories. Weight at age of chub mackerels is compared from the data by China, eastern/western Japan, and Russia with adjusted age on China and Russia. The weight at age for stock assessment is calculated using the submitted data and arithmetic mean of China, eastern Japan, and Russia is recommended.
