辽宁省东沟县黄土坎农场养殖对虾,掌握对虾生活习性和活动规律,实行科学管理、科学投饵,去年万亩虾池产对虾1184吨,平均亩产105公斤,获历史最高水平。其主要措施: 一是下功夫清理虾池。清除池底淤泥,平均下深20厘米,增加养虾池深度,扩大水体,特别是对养虾两年以上的池子和建在沟泡上的池子清除淤泥更为重要。池底淤泥中含有大量残饵、微生物、虾的代谢物,在高温下产生化学还原反应,形成硫化氢,会使对虾中毒死亡。减少敌害,他们在提水前用50—100ppm漂白粉进行杀鱼苗消毒,采用 Last year, 1184 tons shrimp pond shrimp production and 105 mu average yield, the highest level in history. The main measures: First, work hard to clean shrimp pond. Clear the bottom of the mud, an average depth of 20 cm, increasing the depth of shrimp ponds, expanding the water, especially for shrimp more than two years of ponds and ponds built in the bubble on the sludge removal is more important. Bottom sludge contains large amounts of bait, microorganisms, shrimp metabolites, chemical reduction reaction at high temperatures, the formation of hydrogen sulfide, will make shrimp poisoning death. Reduce the enemy damage, they use 50-100ppm bleach to kill fish fry before the water, using
