2003年11月~2004年9月在安徽省扬子鳄繁殖研究中心,观察了人工养殖的成年扬子鳄(Alligatorsinensis)在饲养池和模拟自然生态环境的繁殖区中越冬后的繁殖行为。结果表明,在与扬子鳄自然洞穴的温度和水分条件相似但其他条件相差很大的人工环境中冬眠的扬子鳄具有繁殖能力。越冬后,这些鳄只能在具备其栖息地环境特点的场地成功繁殖,但不能在不具备这种环境特点的场地成功繁殖。本研究拓展了扬子鳄的人工繁殖技术,为扬子鳄人工繁殖场地的兴建提供参考资料。 From November 2003 to September 2004, Alligatorsinensis was cultured in the breeding pool and simulated reproduction habitat of the natural environment in the Yangtze River Alligator Breeding Research Center of Anhui Province. The results showed that alligator sinensis hibernating had the ability to reproduce in an artificial environment that had similar temperature and moisture conditions to the natural caves of Alligator sinensis but which varied greatly from other conditions. After winter, these crocodiles reproduce successfully only on sites that have the characteristics of their habitat environment but can not reproduce successfully on sites that do not possess this environmental feature. This study expands the artificially propagation of Alligator sinensis and provides references for the construction of alligator sinensis breeding sites.
