The influence of the year class size (in numbers) and a stock biomass on the growth rate of 13 cohorts (1971-1983) of the Northwest Atlantic mackerel were investigated. It has been stated that the year class size actually influenced the growth of the examined fish only in the first year of life. The stock biomass was strongly correlated with the growth rate during the first and the second years of life. The density-dependent growth in 3-7 years old mackerel was not observed.
