Case Analysis: How to Solve High Ammonia Nitrogen in Aquaculture Water
Release time:
2023-05-18
1. Case Details:
Time:2023Year4Month
Location: Yangxin County, Huangshi City, Hubei Province
Breed varieties: grass carp
Water quality standard:pH:7.4ammonia nitrogen>1.8Nitrite:0.01
Description: The water color is slightly turbid, and the ammonia nitrogen content is found to exceed the standard obviously.
2. Treatment scheme:
Water transfer detoxification: clear water detoxification safety(Each bottle5LDosage40mu)
Degradation of ammonia nitrogen: probiotic mass (per bag25KgDosage80mu) used first10~20Times water immersion,4~6After hours of activation, the whole pool was splashed; concentrated photosynthetic bacteria powder (per bag1KgDosage3mu) add appropriate amount of water to soak4~6Spill the whole pool after hours. The two are selected according to the size of the water body.
3. Effect feedback:
Under the condition of continuous sunny days, after using bishui detoxification and probiotics group (or concentrated photosynthetic bacteria powder) for three days, the water color recovered fresh and no longer turbid; the content of ammonia nitrogen decreased obviously.
4. Case analysis:
Ammonia nitrogen in aquaculture waterRefers to the water with free ammonia (NH3) and ammonium ion (NH4 ) form of nitrogen.Ammonia nitrogen mainly comes from residual baits, metabolites of farmed animals, remains of aquatic animals and plants and unreasonable fertilization. Excessive ammonia nitrogen content in the water body will cause the following hazards: reduced immunity and resistance of farmed animals, reduced food intake, slow growth, and prone to diseases; it may even cause fish and shrimp poisoning, pull nets, transport bleeding, and death in severe cases.
Bishui Jiedu An: detoxification and water transfer, improve the effect of live bacteria preparations, and reduce the turbidity of water color.
Probiotics group: bacteria and algae double culture, effective degradation of ammonia nitrogen and other harmful substances, improve the resistance of breeding varieties.
Concentrated photosynthetic bacteria powder: high content of photosynthetic bacteria, effective degradation of ammonia nitrogen, nitrite and other harmful substances in water, significantly improve the water quality.
