摘　　要：头足类(Cephalopods)是一类较为高等的海产软体动物,在海洋渔业中占有重要地位。它们复杂的求偶、交配和繁殖行为代表了无脊椎动物交配系统和性别决定体系的进化趋势,也是制约群体大小的直接因素。本文就其繁殖行为学领域的研究状况进行了概括,包括性成熟、交配、受精、产卵直至孵化等头足类繁育的各代表时期,以及微卫星DNA标记技术在繁殖策略中的应用等方面,并对发展前景作了展望,旨在为中国近年来开展的头足类遗传多样性、增殖放流、资源修复等研究与政策制订提供科学依据。Cephalopods are a group of diverse,highly developed marine molluscs,which play an important role in ocean fisheries. Complex courtship,mating and reproductive behaviors of cephalopods represent the evolution trends of the mating and sex-determining system of invertebrate,which are also considered as direct factor to limit the size of the populations. Reproductive behaviors of cephalopods are summarized in detail,including sexual maturity,mating, mate guarding,fertilization,spawning,hatching,etc,as well as the application of microsatellite DNA marker technique in reproductive strategies. The prospects are also pointed out. This paper aims to provide some referential information for the research on genetic diversity,proliferating and releasing,resource restoration done in China in the recent years.
