(1) The water temperature in the shrimp pond should be above 20℃, and the lowest should not be lower than 18℃, and the water temperature can be kept above 18℃ during the whole culture process.
(2) The salinity of the pond water is 10 ~ 30, with the maximum not exceeding 37 and the minimum not lower than 5. The salinity difference with the nursery pond should not exceed 3, otherwise, shrimp seedlings should gradually adapt to transition before stocking.
(3) The 3)pH value should be 7.6 ~ 8.8. If the pH value exceeds this range, please change the water. When the pH value is lower than 7.6, it can be adjusted with lime.
(4) The water depth of the culture pond reaches 80 ~ 120cm, the water quality is fresh, the water color is good, the transparency is 30 ~ 60cm, and there are no harmful organisms such as Gymnodinium.
(5) The seedlings should be planted on the windward side to avoid being injured or killed by waves; When you pour the seedlings, you should immerse the bag in water and pour it out slowly to avoid hurting the shrimp seedlings.
(6) 10:00 ~ 14:00 should be released in cloudy days or sunny evenings, so as to facilitate shrimp seedlings to adapt to the environment quickly after entering the pond.
Seedling releasing operation: When releasing the seedlings, the plastic bag containing the shrimp seedlings should float on the water surface of the shrimp pond. After the water temperature inside and outside the bag is consistent, open the plastic bag, slowly add the pond water into the bag and gently shake it to let the shrimp seedlings swim out automatically.
