(1) Feeding of feed before 1 to 2 days before acclimation.
(2) Low salinity (salinity)
(3) Feeding is stopped during the acclimatization because if the feed is fed during the acclimatization, the feed and the seawater enter into the seedling body, which easily leads to dehydration of the viscera. On the other hand, it should also be considered that the digestive juice of tilapia is strongly acidic, and the high pH seawater enters the intestine along with the feed, and the digestive juice is neutralized, which reduces the vitality of the digestive juice and causes indigestion. This is also a result of domestication. One of the reasons.
(4) In the domestication process, the principle of gradual transition from low salinity to high salinity should be mastered. In low-salt environments (15 or less), the acclimation time should be slightly longer, which is a guarantee for improving the survival rate of domestication.
(5) Damaged fish cannot be used for domestication. Damaged fish will die due to obvious dehydration, even in low salinity seawater.
