在室内水槽进行了不同投饲方法对中国对虾摄食和生长的影响试验。结果表明,中国对虾摄食饱胃后随着投饲间隔时间延长摄食量逐渐增大,3小时接近饱食量;摄食经海水浸泡2小时之配合饲料量略低于未经浸泡者;在饥饿时能摄食自己的粪便;在每日投2~6次中,随着日投饲次数增加,生长速度加快,日投饲6次比2次者生长速度快72%;每日投饲4次时,随着配合饲料在水中保留时间的延长,对虾生长速度加快,一直保留,比只保留1小时者生长速度加快78%。
Effects of different feeding methods on feeding and growth of shrimp in China were tested in indoor sinks. The results showed that the food intake of prawn shrimp increased gradually with feeding time interval, and reached the satiety level at 3 hours. The amount of feedstuff fed 2 hours after immersion in seawater was slightly lower than that of unsweetened ones. Feeding their own excrement; vote in the daily 2 to 6 times, with the increase in the number of daily feeding, the growth rate accelerated, 6 times daily feeding rate of 72% faster than 2 times; daily feeding 4 times, With the extension of retention time of compound feed in water, prawn grew faster and retained more than 78% faster than only retaining one hour.
