蛙类在生长发育过程中有变态现象,蛙卵又是进行细胞学和胚胎学试验的好材料。所以饲养蝌蚪是教学和科研中必不可少的工作。但如饲养方法不当,往往引起蝌蚪大量死亡或长期生长不发生变态。我们经过几年的实验认为,饲养蝌蚪的关键是人工创造一个与自然条件相似的生态环境,并且这个生态环境要随着蛙的生长发育过程的改变而变更。 Frogs have metamorphosis during growth and development, and frog eggs are good materials for cytological and embryological tests. So feeding tadpoles is an essential part of teaching and research. However, improper feeding methods, often causing a large number of tadpoles death or long-term growth does not occur metamorphosis. After several years of experiments, we believe that the key to keeping tadpoles is to create an ecological environment similar to the natural conditions, and this ecological environment changes as the frog’s growth and development process changes.
