虾苗放养。石灰水消毒待7～10天水质正常后即可放苗，对水温要求比较高，适宜的生长水温20℃～30℃，低于15℃时很少摄食。水体应保持高溶氧，溶解氧应在50毫克以上。水体透明度应在30～40厘米。pH值7.0～8.5。放养1.5～3.5厘米的虾苗，放养密度为4000～7000尾/亩。放苗时将盛虾苗塑料袋放置塘内30分钟后再打开，使虾苗逐渐适应塘内水温，有利于提高虾苗成活率。放养1个月左右，可适时放养50～250克/尾的花白鲢60～100尾/亩。淡水龙虾是底栖甲壳动物，适当混养中上层滤食性鱼类，不仅可改善龙虾的生长环境，而且可作塘内缺氧的指示鱼类。但不要混养肉食性和吃食性鱼类，以免影响龙虾生长。
