中国大鲵的繁殖生态暨行为学观察研究

在秦岭地区天然水域大鲵简易繁苗法和仿生态亲鲵培育池繁苗的基础上,论述了促成大鲵繁苗的8项生态因子．秦岭地区大鲵繁育日度与江汉平原区存在较大差异;大鲵在不同产区繁殖期和繁殖盛期的时间,建议各地应抓住当地的繁殖时机做好繁苗工作．记述了大鲵在催情效应期亲吻、顶腹、嬉戏、交尾等繁殖行为．对大鲵繁殖配组的性比、繁殖日度、繁殖时间、雌雄性腺发育同步等问题进行了讨论．

Productive ecology and behavior of Chinese giant salamander (Andrias davidianus)

Based on the simple and easy productive method of Chinese Giant Salamander and multiplying by establishing ecological breeding pond in Qinling Mountains, 8 ecological factors are narrated which help to bring about the success in production. Sum of heat of breeding period of Giant Salamander has a big gap between Jiang-Han plain (Shashi City, Hubei Province) and area of Qinling Montains. There are various periods of time of production in different places, and the very opportune moment should be take advantage of in relevant place. Sexual behaviors, like pairing, spawning, ejaculating are recorded, and be divided into kissing, gore-abdomen, sporting, and pairing (fig. 3). In additional, several items have been discussed which are adaptation of Giant Salamander to water temperature from South to North, determination of period of breeding time in different place and developing synchronism of female and male sex gland.
