南美白对虾以其生长速度快,盐度适应范围广,抗病力强,饲料营养要求低等特点,成为当今世界公认的三大优良虾种之一。近几年在我国北方开始大面积推广养殖。2001年,我们引进南美白对虾苗种31万尾,利用黄河三角洲滨海重盐碱地渗水与淡水混合进行离子调节后作为养殖用水,经142天的养殖,共产商品虾5586公斤,平均规格13.6厘米,回捕率82.6％。1 池塘条件及池水调兑:试验选在利津县明集乡的5个池塘进行,池塘总面积30亩,有效水深2.0米,池塘为新开挖的,单池配备ZY3G叶轮增氧机两台。进水后用5～10ppm漂白粉或O.1ppm的二氧化氯消毒一次,养殖池水由盐碱地地下渗水(S=20‰左右)与黄河水混合后,配兑为10～15％0的盐度,由于渗水中钾离子偏低,再添加70～100ppm氯化钾后作为养殖用水。
Penaeus vannamei has become one of the three fine shrimp species recognized in the world today with its fast growth rate, wide range of salinity adaptation, strong disease resistance and low feed nutrition requirements. In recent years in northern China began to promote large-scale breeding. In 2001, we introduced 310,000 South European white shrimp breeds. After we used ion exchange and freshwater mixing in the Yellow River Delta to make ion regulation, we used aquaculture water. After 142 days of breeding, we produced 5,586 kg of commercial shrimp with an average size of 13.6 cm Catching rate of 82.6%. 1 pond conditions and pool water exchange: The test selected Liji County Mingji Township, 5 ponds, the pond a total area of 30 acres, the effective depth of 2.0 meters, the pond is newly excavated, single pool equipped with two ZY3G impeller aerator . After the water is disinfected with 5 to 10 ppm of bleaching powder or 0.1 ppm of chlorine dioxide, the aquaculture water is mixed with the Yellow River water by subsurface water infiltration (S = 20 ‰ or so) of saline-alkali soil and then mixed with 10 to 15% As the infiltration of potassium in the low, then add 70 ~ 100ppm potassium chloride as farming water.
