摘　　要：在2012年4月至2013年6月对白洋淀的子陵吻虾虎鱼Rhinogobius giurinus进行分期采样后,进行生物学的初步研究。其中包括子陵吻虾虎鱼Rhinogobius giurinus的栖息习性、生长发育、摄食、繁殖以及对外界环境条件适应等生物学特性。子陵吻虾虎鱼属一年生,当年孵化,次年成熟,繁殖之后死亡。子陵吻虾虎鱼的食物大都以浮游动物、微型昆虫幼体及藻类为主。子陵吻虾虎鱼全长和体重是按照W=0.525L-1.365 2正相关的,其中W是子陵吻虾虎鱼的体重,L是子陵吻虾虎鱼的全长。子陵吻虾虎鱼鱼群一般由2龄及以下鱼龄的鱼组成。卵巢的发育为多次成熟,分批次产卵。精巢为乳白色块状。The biological characteristics of the Rhinogobius giurinus in Paiyang Lake have been prelimi- narily investigated during April 2012 to June 2013 with stage sampling. The investigations are about habitat habit, growth, feeding, fertility, and so on. All lifetime of the Rhinogobius giurinus is one year. The mature age of female and male is 2 age. They died when they gave birth to the babies. The Rhinogobius giurinus is feed on zooplankton, micro insect larva and al- gae. The relationship between length and weight is expressed as W=0. 525 L--1.365 2.
