The maturity and spawning of the yellow goosefish Lophius litulon were studied using samples collected monthly
from January to December 2018 from the coastal waters of Korea. We analyzed monthly changes in maturity stage,
gonadosomatic index (GSI), total length (TL) at 50%, 75%, and 97.5% group maturity, egg diameter and fecundity.
The spawning period was from January to June. The size of eggs spawned was between 0.30 to 1.28 mm. Fecundity
varied between 328,314 to 1,624,783 eggs. The percentage of sexually mature females estimated from a logistic function
was over 50% at 48.67 cm TL, 75% at 56.76 cm TL and 97.5% at 74.89 cm TL.
