| Popis: | Fishes belonging to the family Clinidae in South Africa display super-embryonation, a rare reproductive mode were females gestate broods at different gestational stages, but little is known regarding the mating systems of this family. Here we tested the hypothesis that multiple males would contribute not only to the offspring of each female, but that several males would contribute to each brood, by sampling Muraenoclinus dorsalis from three sampling locations along the west and south-west coast of South Africa. Larval (n = 97) and maternal (n = 14) genotpyes, generated with newly developed microsatellites, were used to estimate the number of potential mates per female. Our results show that up to 78% of females displayed multiple mating with an average of 2·1-2·2 males. In addition, 39-42% of females displayed polyandry with an average of 1·5-1·6 sires per brood. This study provides the evidence for multiple mating and polyandry within a clinid fish characterized by super-embryonation that offers important baseline information regarding rare reproductive strategies, highlighting several gaps in our knowledge concerning clinid reproduction and mating systems. |
