Abstract The general pattern of gametogenic activity for M. e. aoteanus was comparable with that of Mytilus edulis planulatus reported from Western Australia, although a majority of the latter species were resting or of indeterminate sex during the summer, when seawater temperatures were warmer than in New Zealand. The apparent coincidence of spawning periods of the mussel species M. e. aoteanus, A. maoriana, Perna canaliculus and Xenostrobus pulex, which overlap spatially on New Zealand shores, raises the possibility of interspecific competition among larvae for settlement space.
