采用塑料膜棚覆盖养虾池的方法,对不同水温下饲养对虾(Penaeus orientalis)仔虾至幼虾的效果进行了对比实验。结果表明:水温对仔虾的生长速度与仔、幼虾的成活率均影响甚大,从而直接影响到养殖成本。据此,提出了新的放养时机,以有利于调整养虾生产结构,改善养虾生态环境。
A plastic film shed was used to cover shrimp ponds. The effects of feeding Penaeus orientalis larvae to juvenile shrimp under different water temperatures were compared. The results showed that: the water temperature on larval growth rate and survival rate of young and juvenile shrimp have a great impact, which directly affects the breeding costs. Accordingly, a new timing of stocking is proposed in order to adjust the structure of shrimp production and improve the ecological environment of shrimp farming.
