Abstract
Male and female capelin (Mallotus villosus Müller) were captured in 1993 at the start of spawning and males were captured in 1995 at the end of the spawning period. All male fish from both years died within 6 weeks of capture. Spent males captured in the wild showed almost empty testes with very few residual sperm and no evidence of developing spermatocytes. All female fish survived the first 6 weeks and over 50% survived 20 weeks. Sampling of the surviving females after 20 weeks showed evidence of prior spawning and progressive development of oocytes for the next summer's spawning season. It was concluded that while males may be semelparous, females are inherently iteroparous.
