Study on Age, Growth and Reproductive Biology of Chiloscyllium plagiosum from Southern Coast of Fujian

Abstract

软骨鱼类是古老的鱼类,在形态特征的演化上较为守旧,通常被认为是低等鱼类。但其在生殖方面却有着许多先进的特点,不同于硬骨鱼而更接近于两栖类和羊膜动物,因此其生殖生物学研究相当吸引人。随着鲨鱼利用价值的不断提高和对资源保护的重视,对鲨鱼的开发利用和研究都成了当前科学研究的热点。本论文通过对闽南近海条纹斑竹鲨(ChiloscylliumplagiosumBennett)的周年采样,研究了其年龄结构、全长--体重关系和生长特性,并根据生物学和组织学的观察研究了其配子发生、卵壳腺的结构与功能以及生殖生物学特性,为软骨鱼系统进化研究提供了参考依据,同时也为合理开发、利用闽南近海条纹斑竹鲨资源提供了参考依据...The chondrichthyan is one of the oldest living groups of jawed vertebrates. They are often considered to be primitive, but their reproductive system possesses some advanced characteristics and more similar to amniotes and amphibia than teleosts. So the reproductive biology of chondrichthyan fishes attracted many researchers. Recent years, exploitation and research of sharks is becoming hot topic. ...学位:理学硕士院系专业:海洋与环境学院海洋学系_海洋生物学学号:20022701
