Maturation and fecundity of mackerel (Scomber scombrus L.) in Northwest Atlantic

Abstract

Studies were carried out in 1983-1984 on gonad development, sex ratio, and absolute and relative fecundity of mackerel from a pre-spawning concentration in Northwest Atlantic. Relationship between gonad development and fish length and sex was determined. Absolute fecundity varied from about 240 thousand to 1160 thousand eggs and correlated most strictly with the fish length.
