Gametogenesis, reproductive cycle, egg diameter composition and gonad index of the black-lined limpet, Cellana nigrolineata, were histologically examined. Specimens collected from the rocky intertidal zone of Hamdeok, Jeju from July 1997 to June 1998. The black-lined limpet has an unpaired gonad located at the ventro-anterior part, underneath the visceral mass. The gonad index increased from May when water temperature increased and reached maximum in August. It began to decrease from September thereafter, maintain a low value from January to April. The following reproductive cycle were classified based on the monthly changes of the histological features and sizes of oocytes in the gonad: recovery stage (November to April), active stage (March to June), ripe stage (May to October), spent stage (August to December). Spawning occur once a year between September and October. The black-lined limpet appeared to be gonochorism, neither sex change nor hermaphroditie.
