1995年以来，由于控温养殖因原来的封闭性模式和垫沙养殖有较多的缺陷，故探求更合理、科学的研究已被业内科技人员普遍重视。到目前为止一些地区采用既保温又采光的简易大棚和池内无沙养殖的模式已日趋成熟。但就全国而言还未全面铺开，主要是养殖者对无沙养殖的几种模式特点? Since 1995, as a result of the original closed-loop culture and mat sand culture have more defects, so to seek more reasonable and scientific research has been widespread attention of industry scientists.

However, it has not yet been rolled out in an all-round way across the country, mainly due to several model features of farmer’s cultivation without sand.
