ABSTRACT The population biology of Doropygus pulex and Gunenotophorus globularis, symbiotic copepods within the ascidian Polycarpa pomaria, was studied at a locality off western Sweden. Both species showed a seasonal pattern of reproduction, having adult females overwintering and a new generation of copepods appearing during autumn. Only Doropygus utilizes the long life-span of the host and possibly reaches ≈ 15 months, while Gunenotophorus reaches ≈ 1 year. While the males of Doropygus were as frequent as the females, the male of Gunenotophorus was recorded only in late autumn. Doropygus pulex was found in 92% of the ascidians, usually with several individuals in each host. Doropygus pulex showed an opportunistic life-style with considerable variation in oviposition and a prolonged release of larvae. This may be reflected in its occurrence in many host species. Gunenotophorus globularis occurred in only 46% of the ascidians and most often with only a single specimen in each host.
