In addition, the number of days from the start of incubation until hatching was 14 days in the experimental group and 18 days in the control group. At this time, the hatching rate of the control group was 4,000 fish, the yield up to the juvenile shrimp with a body length of 1 cm was 20%, and the thickness increase coefficient was 1.1, which was almost the same level as before. On the other hand, the hatching rate in the experimental area is 1
The yield of 8,000 larvae and juvenile prawns was 90%, and the thickness increase factor was 1.5, which were significantly higher than the control group. In the experimental area, the cannibal shrimp did not eat each other, which seems to have significantly improved the yield.
