Reproductive Cycle of the Abalone, Haliotis discus hannai Collected from Jindo of Korea

ABSTRACT This study histologically describes the gonadal development and reproductive cycle of the abalone, Haliotis discus hannai inhabiting Jindo on the southern seashores of Korea. Gonads displayed histologically definitive seasonal changes. The female ratio (F/F + M) was 57% (n = 154/271). The gonad index (GI) of both males and females was the highest (3.3 and 3.9) in June and was the lowest (1.1 and 1.1) in December. The condition index (CI) and meat weight rate (MWR) were highest in May and lowest in October. The pattern of changes in the GI, CI and MWR were similar to the pattern of seasonal changes in gonadal tissues. The reproductive cycle was divided into an inactive stage (November–December), early active stage (January–March), late active stage (March–April), ripe stage (May–June) and spent and degenerative stage (July–October). The main spawning period of Haliotis discus hannai was July to August at Jindo in 2013. Keywords: Haliotis discus hannai , reproductive cycle, main spawning period
