With the continuous advancement of the breeding process, October has reached the late stage of the outer pond breeding. The accumulation of matter throughout the year makes the breeding water body more and more bad and unstable. With the decrease of temperature, ammonia nitrogen and nitrite are easy to appear too high. Long-term cloudy days lead to too thin water quality and poor food for fish and shrimp.
Address: Xintan Salt Farm, Binhai Port County, Yancheng City, Jiangsu Province
Cultivation area: 120 mu * m (carp and shrimp)
Time: October 20th
Water quality index: pH8.3 nitrite 0.2 ammonia nitrogen 0.2
Description of 1.: The water body is turbid and the fertilizer is not enough. Under microscopic examination, there are few algae and high nitrite. Carp eats little or no food.
2. SolutionsFirst, clear water detoxification safety (30 mu * rice barrel) is used to break the stratification of water body and enhance the permeability of water body, then EM golden dew (20 mu * rice barrel) is used to quickly fertilize water with quick-acting fertilizer essence (5 mu * rice barrel) to promote the reproduction of algae in water body and improve the diversity of algae in water body; And supplement bacteria to reduce nitrite, ammonia nitrogen and other harmful substances in aquaculture water.
3. water transfer before and after the effect of contrast:
Before water transfer:
After water transfer:
4. effect feedback:After three days of medication, the water color gradually returned to green, and the number of algae also increased significantly, mainly green algae. Nitrite dropped to about 0.1, and carp also resumed eating.
5. summary:It is inevitable that there will be some abnormal indicators in the water quality in the later stage of breeding, but the most important thing is to ensure the normal feeding of the farmed animals. Under the condition that the farmed animals do not have obvious physiological hypoxia, it is necessary to ensure that the dissolved oxygen in the water body is sufficient, and the water should also have a certain degree of fertilizer. Only in this way can the farmed animals eat normally and the farmers will rest assured. Therefore, the cultivation of the late moderate water fertilizer is also very necessary.
