Japanese shrimp survival rate low remedy

When the survival rate of shrimp in the pool is found to be low, appropriate remedial measures should be taken.
First of all, carefully analyze and ascertain the reasons for the low survival rate of shrimps, and eliminate the factors that are not conducive to the growth of shrimps. We should start from the following major aspects:
1) Whether the shrimp seedlings are robust, whether they have reached stocking standards, and whether the transportation methods and seedling release methods are reasonable;
2) Whether the shrimp pond bottom quality and water quality conditions are suitable, especially whether the water temperature and salinity are close to the nursery. Or whether there is residue of disinfectant in the shrimp pond, such as the presence of residual chlorine, whether there is a mutation after releasing the seedlings. Stocking in the middle of the cultivation pool should pay attention to the phenomenon of hypoxia;
3) Whether the enemy's creatures in the pool are completely removed.
After identifying the above reasons, appropriate measures should be taken to eliminate the factors that are not conducive to the growth of shrimp.
Followed by different conditions to take fill seedlings, re-release of seedlings and strengthen management and other measures. If the survival rate of the shrimp seedlings is less than 50% within 15 days after seeding, seedlings shall be made. In order to reduce the individual differences in the successive release of shrimp seedlings, the seedlings to be replanted should select individual large and robust shrimp seedlings. If the original shrimp is placed in the middle of the cultivation pond, the added seedlings should be put directly into the big pool.
The survival rate of the shrimp seedlings was found to be less than 30% within 30 days of seedling release. If the seedlings were sufficient, restocking would not delay the production and harvest season. The ponds could be re-sterilized and the remaining shrimps could be removed and replaced. seedling. If the source of the shrimp is insufficient, or if it will delay the production and harvesting season, measures should be taken to strengthen the custody, so that the remaining shrimp seedlings can grow rapidly, increase the individual's weight, raise the shrimp, and sell well to compensate for some losses.
