Description of life cycle and mating behavior Orange roughy are synchronous annual spawners (Ref. 7030). They form dense spawning aggregations over sea hills and slopes. Eggs and sperms are shed into the water at the same time. Individual males appear to spawn over a 1-2 week period and females spawn for up to 1 week. Little is known of the larvae and juveniles.
