黑斑侧褶蛙蝌蚪栖息地和饲养研究

Study on the Habitat and Feeding of Pelophylax nigromaculata

黑斑侧褶蛙产卵、蝌蚪水中生活时期多与稻田相关,稻田是蛙类的最佳栖息地。蛙类从卵到幼蛙成活率约3%,很低。影响繁殖成活率因子从大到小的顺序是水源>挖沙>农药>捞鱼>水质>天敌。人工饲养蛙卵,放归田间,实验数据支持这一保护措施。

Rice field is ideal habitat for frog Pelophylax nigromaculata,due its close association with frog’s spawn and growth.There was a very low survival rate of only 3%for frogs from egg to young frog.The factors affecting the survival rate of frog reproduction were water source,dredging,pesticides,fishing,water quality and natural enemies in descending order.Frog eggs were raised by artificial method,and then released into the field,aprotective measure supported by experimental data.
