淡水白鲳一般每667m~2池塘产量达400—500kg。现将其池塘养殖和常见病防治技术介绍如下: 一、生态特性 淡水白鲳属热带鱼,杂食性,种内一般不互相残杀,鱼种在饥饿情况下会相互咬伤,有的因尾鳍被吃掉而死亡;适应水温12℃—35℃,最适生长水温24℃—32℃,当水温低于12℃时大部分鱼失去平衡,会有冻死的危险;耐低氧能力较强,水中溶氧0.5mg/L时仍然生存,适宜在较肥的池中养殖;耐盐性高,能在盐度5‰—10‰的环境里正常生长;喜生活于微酸性水中,pH值适应范围为5.6—7.4;性情温驯,喜栖息于水体中下层,有成群活动的习性,容易捕捞。
Freshwater pomfret is generally produced at a rate of 400-500kg per 667m ~ 2 ponds. Now its pond culture and common disease prevention and control technology introduced as follows: First, the ecological characteristics of the freshwater Paphia is a tropical fish, omnivorous, species generally do not kill each other, the species in hunger will bite each other, and some due to caudal fin was eaten And died; adapt to the water temperature of 12 ℃ -35 ℃, the optimum temperature of 24 ℃ -32 ℃, when the water temperature is below 12 ℃ most of the fish out of balance, there will be the risk of freezing dead; strong resistance to hypoxia, water Dissolved oxygen 0.5mg / L still survive, suitable for more fat pond culture; high salt tolerance, in the salinity of 5 ‰ -10 ‰ normal growth environment; hi living in slightly acidic water, the pH range of adaptation 5.6-7.4; temperament tame, hi habitat in the lower water, there are groups of habits, easy to catch.
