细鳞鱼,是我国低温水域所栖息的一种较大型鲑科鱼类河流定居种。近年来,资源濒临绝迹,在华北已由原来的连续点状分布变为现在的孤立点状分布状态。为保护及开发这一珍贵资源,国内一些单位对细鳞鱼的繁殖进行了研究。黄浩明(1988)曾报导在封闭式的湖泊、水库中栖居及繁殖并获得发眼卵。白桂芝等(1999)报导利用水泥池试养野生细鳞鱼试验,但利用水泥池培育亲鱼进行繁殖至今未曾见过报道。本课题是在细鳞鱼移植驯养的基础上进行亲鱼培育达到成熟产卵的。现将研
Fish scales, is China’s low-temperature waters habitat a larger species of salmonidae river settlements. In recent years, resources are on the verge of extinction, changing from the original point-like distribution to the present isolated point-like distribution in North China. In order to protect and develop this precious resource, some units in China have conducted researches on the propagation of bellfish. Huang Haoming (1988) reported that dwelling and breeding in enclosed lakes and reservoirs and obtaining eye-covered eggs. Bai Guizhi et al. (1999) reported that the test of wild planarians in cement ponds was conducted. However, the use of cement ponds to breed broodstock has not yet been reported. This topic is in the broodstock transplanted domestication on the basis of broodstock to achieve mature spawning. Now research
