项目摘要

Apogonid and syngnatid fishes are representative groups in which sex-roles are reversed. In the sex-role reversed species, female reproductive success is generally limited by availability of males, unlike in the majority of animals. We have investigated life histories and reproductive strategies of some apogonid and syngnatid fishes in Uwa Sea, Shikoku, Japan for these several years. In Apogon doederleini, the most intensively studied species, detailed data were obtained on growth, migration, reproductive success, mate change and filial cannibalism from identified individuals. From analysis of these data, we found that filial cannibalism by mouthbrooding males is the age-specific reproductive stragegy. From the preliminary analysis of fat, protein and carbon contents in body parts of A.doederleini, we examined the physical condition of males who performed filial cannibalism and estimated energetic costs entailed in mouthbrooding. In the pipefish Corythoichthys haernatopterus, we found that pair-bond is usually maintained throughout the entire breeding season and that serial monogamy is due primarily to mate guarding by females.
其中,天竺鲷科和海龙科是性别角色颠倒的代表性类群。在性别角色颠倒的物种中,雌性生殖成功通常受到雄性可用性的限制,这与大多数动物不同。本研究对日本四国宇和海的一些长尾和海龙类鱼类的生活史和繁殖策略进行了调查。在Apogon doederleini,最深入研究的物种,详细的数据获得的增长,迁移,繁殖成功,配偶的变化和子同类相食,从确定的个人。通过对这些数据的分析,我们发现口孵雄鱼的子相食是其特定年龄的繁殖策略。通过对多德氏圆腹蛛身体各部分脂肪、蛋白质和碳含量的初步分析,研究了进行子相食的雄性圆腹蛛的身体状况,并估算了口相食所需的能量消耗。在海龙Corythoichthys haernatopterus,我们发现,配对债券通常是保持在整个繁殖季节和串行一夫一妻制主要是由于交配守卫的女性。
