三斑海马择偶行为的观察与分析

Mate choice observed in the three-spotted Hippocampus trimaculatus Leach

在人工养殖的条件下,研究三斑海马(Hippocampus trimaculatus Leach)选择配偶与交配的行为学。通过3组试验,对三斑海马的异性规格、异性活力、同性间的配偶竞争行为等方面进行观察记录。结果表明,三斑海马选择配偶时,会选择与自身规格差异不大的异性,强壮、耐力好的海马易赢得配偶。在同性间的配偶竞争中,较大规格的雄性个体的竞争能力也强。雌海马选择雄性配偶的规格要大于或等于自身个体,雄海马则相反。掌握这些规律对水产养殖过程中构建三斑海马的择偶标准与繁育生产有指导作用。

Under the farmed conditions, we recorded the mate choice of the Hippocampus trimaculatus Leach by three group experimental observations： heterosexual specifications, heterosexual activity and homosexual spouses competitive behavior to research how they choose and mate a spouse. The result shows they choose a spouse are of the opposite sex with similar specifications. The study has shown the stronger , better endurance ones win spouse easily. In the homosexual spouse competition , the larger, the more competitiveness. The female hippocampus select male spouse which are greater than or equal to their own individual specifications, while the male is contrary. It plays guiding roles to build the Hippocampus trimaculatus Leach mate with the production of artificial breeding environmental conditions when we master these laws.
