养虾池条件及整治 罗氏沼虾属热带虾类,成虾可适应的水温为18—38℃。当水温下降至18℃以下时,活动减弱,摄食减少,生长缓慢。在适温范围内,水温高,生长快。夏、秋季水温多在25—32℃之间,生长良好。在华南地区,多在清明节以后才能放养虾苗,入冬前收获,养殖时间半年左右。因此,要选择条件适宜的池塘,抓紧生产季节,充分利用温度适宜的时间养殖,使虾
Conditions and treatment of shrimp ponds Macrobrachium is a tropical shrimp, shrimp can adapt to the water temperature is 18-38 ℃. When the water temperature dropped below 18 ℃, the activity weakened, feeding reduced, slow growth. In the temperature range, high water temperature, fast growth. Summer and autumn, more water temperature between 25-32 ℃, good growth. In southern China, more after the Ching Ming Festival stocking shrimp, harvest before winter, breeding time about six months. Therefore, to select the appropriate conditions of the pond, pay close attention to the production season, make full use of temperature appropriate breeding time so that shrimp
