Spawning Behavior in a Non-Teleost Actinopterygian: Genetic Evidence for Both Monogamy and Polygamy in Amia

The bowfins, Amia, have been regarded as promiscuous or polygynous spawners, although this has not directly observed. Species of Amia spawn largely at night in male-constructed and male-guarded nests, making it difficult to view spawning behavior. Furthermore, many species, field observations behavior do always match genetic observations. To investigate the mating system we collected fin tissue from guarding males a sample associated eggs fry 15 broods assess number parents involved each brood. Using these tissues, genotyped individuals 11 microsatellite DNA loci. genotype male was known; inferred primary female by subtraction, using most abundant genotypes known genotype. We polygamy (presence multiple fathers mothers) cases where there more than single locus for which could be explained parental genotypes. Among sampled broods, seven contained offspring male–female pair. Fry eight show evidence polygamy: one brood, an extra-pair male; five least additional female, two also involvement determined whether parent female. Thus, nearly half our were both behaviorally genetically monogamous, while other polygamous. It suggested previously that bowfin may with male, but are no behavioral support claim data cannot discern females nest. conclude is monogamous weakly polygynous. With respect evolution systems fishes, interesting representing member Holostei sister group teleosts, albeit opportunistic participation either extra both. A review literature on non-teleostean ray-finned fishes suggests studies fascinating taxa warranted.
