How to treat the case of ciliate treatment in Penaeus vannamei culture pond?

In recent years, the organic matter in seawater has increased, and there are also many ciliated eggs in the water. When the bottom environment is poor, the water lacks the calcium source that shrimp can absorb, and the shrimp's physique is not strong, ciliates are easy to parasitize on the shrimp's body surface, and then continue to reproduce, which finally affects the shrimp's feeding and growth.

1, basic information

Technician: Xie Weiwei of Beijing Water Century Biotechnology Co., Ltd. Work location: gao ling cun, Potou Town, Potou District, Zhanjiang City, Guangdong Province, Time for filling out the form:

2. Test items and test results

(1) Basic information

Area: 45 mu water depth: 1m Main species: Penaeus vannamei water color: green feeding status: general death status: none.

Recent drug use: nano-black gold, concentrated spores on water surface, Jieduling and probiotics.

(2) Water quality testing

1，pH: 8.3？ 2. Ammonia nitrogen: -3. Sulfite:? - ? 4. Dissolved oxygen: not measured

(3) Microscopic examination

Green algae is dominant, and Microcystis is rare. There are many ciliates on the surface of shrimp.

3. Problem analysis

Shrimp feels rough and it is not long. There are many cilia on the surface of shrimp, which absorb the nutrition of shrimp. Shrimp is difficult to shed its shell, so it is difficult for shrimp to grow up.

4. Treatment plan

Xianxianjing 17 bottle? Total effect: 5 packages of Xianxianjing 18 bottles and 7 packages of Jieduling.

5. Track the processed results.

Water quality: 1,? PH value: 8.5 2, ammonia nitrogen: -3, sulfite: -4, dissolved oxygen: not measured.

Conditions for breeding animals: the feeding speed of shrimp is obviously accelerated, the growth speed is much faster, the body surface of shrimp is very smooth, and the microscopic examination of shrimp ciliates is rare.

6. Case study

In recent years, the organic matter in seawater has increased, and there are also many ciliated eggs in the water. When the bottom environment is poor, the water lacks the calcium source that shrimp can absorb, and the shrimp's physique is not strong, ciliates are easy to parasitize on the shrimp's body surface, and then continue to reproduce, which finally affects the shrimp's feeding and growth. When there are many ciliates on the surface of shrimp, it must be killed. Compared with pesticides, heavy metal pesticides are much less irritating, but they will be killed when the weather is good. In the case of more ciliates, it will be more thorough to use them twice, and detoxification should be carried out after insecticidal treatment.
