The maturation and spawning of red seabream Pagrus major were investigated using 1,014 samples collected monthly
from January to December of 2018, in the South Sea of Korea. Based on monthly changes in maturity stage and
gonadosomatic index, the spawning period was estimated to be between April and August, with peak spawning occuring
from May to June. Fecundity varied between 228,996 and 4,544,948 eggs. The relationship between fecundity (F)
and fork length (FL) in this species can be expressed by the equation F=0.4869FL3.9452 (R2=0.7448). Using a logistic
function, the percentage of sexually mature females was estimated to be over 50% for fish with a FL of 35.3 cm.
