Title: Intensive genetic assessment of the mating system and reproductive success in a semi-closed population of the mottled sculpin, Cottus bairdi

Description: Most genetic surveys of parentage in nature sample only a small fraction of the breeding population. Here we apply micro satellite markers to deduce the genetic mating system and assess the reproductive success of females and males in an extensively collected, semiclosed stream population of the mottled sculpin fish, Cottus bairdi. In this species, males guard nest rocks where females deposit the eggs for fertilization. The potential exists for both males and females to mate with multiple partners and for males to provide parental care to genetically unrelated offspring. Four hundred and fifty-five adults and sub adults, as well as 1259 offspring from 23 nests, were genotyped at five polymorphic microsatellite loci.
