The reproductive cycles of Chthamalus stellatus (Poli) and C. montagui Southward in south-western Ireland

Research output: Contribution to journalArticlepeer-review

Abstract

The reproductive cycles of two intertidal barnacles, Chthamalus stellatus (Poli) and C. montagui Southward, were studied at Lough Hyne Marine Reserve, Cork, Ireland, over 28 months. In both species there were seasonal trends in development of the male and female reproductive organs with, for example, the ovaries regenerating while eggs were being brooded. Breeding occurred mainly during June-August but also at other times. The sizes of the ova and eggs of the two species were compared and the timing of the cycles relative to other areas considered.
