一、Thoroughly solve a series of problems caused by excessive ammonia nitrogen in fish ponds, and the effect will be seen in three days.
The main reasons for excessive ammonia nitrogen in fish ponds include water source pollution, bottom pollution, fertilizer pollution, deterioration of leftover bait, unreasonable feed feeding, bottom deterioration, sudden weather changes, and external pollution.
1. Water source pollution: water with too high ammonia nitrogen content is introduced when new water is injected, such as polluted industrial and agricultural water.
2. Bottom pollution: a sudden rise in ammonia nitrogen after the bottom is polluted, which is common in hot summer and often occurs in ponds with excessive silt accumulation or long-term bottom sewage discharge.
3. Fertilizer pollution: Excessive fertilization during the breeding process, such as excessive use of nitrogen fertilizers such as urea and ammonium chloride, may cause a sudden increase in ammonia nitrogen in the water before the algae are cultivated.
4. Decay of leftover bait: Too much feed is fed, resulting in a lot of leftover bait at the bottom of the pond, which in turn causes decay and is also likely to cause a rise in ammonia nitrogen.
5. Unreasonable feed feeding: Excessive feed feeding causes nitrogen-containing substances such as protein and amino acids in the feed to enter the water and become a source of ammonia nitrogen.
6. Deterioration of the bottom quality: If the sludge at the bottom of the pond is not removed for a long time, the ammonia nitrogen and sub-salt produced by the decomposition of organic matter at the bottom of the pond will enter the water.
7. Sudden weather changes: In the hot season, the temperature changes quickly, it is hot and rainy, the air pressure is low, the dissolved oxygen content in the water is reduced, etc., it is very easy to cause the death of beneficial microorganisms and algae in large numbers.
8. External pollution: The aquaculture water source is polluted by external factors, such as domestic sewage, industrial wastewater, etc. entering the aquaculture water body.
9. These factors will cause the concentration of ammonia nitrogen in the fish pond to increase, which will damage the immune system of aquatic organisms and make aquatic organisms susceptible to invasion by other pathogenic microorganisms.
In addition, excessive ammonia nitrogen in fish pond water will cause chronic or acute ammonia nitrogen poisoning in aquatic organisms.
The hazards of chronic ammonia nitrogen poisoning are:
(1) reduced food intake and slowed growth;
(2) tissue damage, reduced oxygen transport between tissues;
(3) fish and shrimp need to exchange ions (sodium, calcium, etc.) with the water body. Excessive ammonia nitrogen will increase the permeability of the gills and damage the ion exchange function of the gills;
(4) It puts aquatic organisms in a state of stress for a long time, increases the susceptibility of animals to diseases, and reduces growth rate;
(5) reduces reproductive capacity, reduces the number of eggs, reduces the survival of eggs, and delays spawning and reproduction.
The hazards of acute ammonia nitrogen poisoning are: aquatic organisms show excitement, lose balance in the water, convulsions, and even death in severe cases.
Don’t know how to deal with excessive ammonia nitrogen in the fish pond? Water quality problems are complex and diverse, and you don’t know how to judge? Don’t know how to match products to improve water quality? Will there be frequent rebounds in the treatment of excessive ammonia nitrogen and nitrite? One-on-one guidance from aquatic experts, based on your water quality problems and scientific proportions of the breeding area, to help you cultivate ideal water quality that is fat, tender, lively and refreshing. Including various water quality control and prevention in later aquaculture, experts will give more reasonable and effective suggestions… …
鱼塘氨氮超标怎么处理？
您是否在为这样池塘氨氮超标怎么处理犯愁？
专家指导，帮您解决鱼虾蟹塘氨氮超标，久高不下的问题
水产专家建议：按比例配合使用水产菌种，帮您培育出肥、嫩、活、爽的理想水质 电话：+86 18237136133
一、彻底解决鱼塘氨氮超标引起的一系列问题，三天见效
引起鱼塘氨氮超标的主要原因包括水源污染、底质污染、肥料污染、残饵剩料腐坏、饲料投喂不合理、底质恶化、天气突变、外源污染。
1、水源污染：注新水时引入了氨氮成分过高的水质，如受到污染的工农业用水。
2、底质污染：底质收到污染后造成氨氮突升，常见于高温夏季，多发生在淤泥积累过多或长期不改底排污的塘口。
3、肥料污染：养殖过程中施肥过量，如使用尿素、氯化铵等氮肥过量，可能导致藻类还没培育出来，水体中的氨氮就会出现突升情况。
4、残饵剩料腐坏：投喂的饲料过多，导致塘口底部残饵剩料较多，进而引发了腐坏，也很容易造成氨氮物质上涨。
5、饲料投喂不合理：过量投喂饲料，导致饲料中的蛋白质和氨基酸等含氮物质进入水中，成为氨氮的来源。
6、底质恶化：长期不清除池底淤泥，池底有机物分解产生的氨氮和亚盐就会进入到水体中。
7、天气突变：高温季节，气温变化快，闷热多雨，此时气压较低，水体溶氧量降低等情况，非常容易造成有益微生物以及藻类大量死亡。
8、外源污染：养殖水源受到外部污染，如生活污水、工业废水等进入养殖水体。
9、这些因素都会导致鱼塘中的氨氮浓度升高，对水生生物的免疫系统造成破坏，使水生生物易受其他病原微生物的侵袭。
除此之外，鱼塘水氨氮超标会造成水生生物慢性或急性氨氮中毒。
慢性氨氮中毒危害为：(1)摄食降低，生长减慢；(2)组织损伤，降低氧在组织问的输送；(3)鱼和虾均需要与水体进行离子交换(钠，钙等)，氨氮过高会增加鳃的通透性，损害鳃的离子交换功能；(4)使水生生物长期处于应激状态，增加动物对疾病的易感性，降低生长速度；(5)降低生殖能力，减少怀卵量，降低卵的存活力，延迟产卵繁殖。
急性氨氮中毒危害为：水生生物表现为亢奋、在水中丧失平衡、抽搐，严重者甚至死亡。
鱼塘氨氮超标不知道如何处理？水质问题复杂多样，不会判断？不知道如何搭配产品改良水质？氨氮、亚硝酸盐超标治理是否会出现经常反弹现象？水产专家一对一指导，根据您的水质问题和养殖面积科学配比，帮您培育出肥、嫩、活、爽的理想水质。包括后期水产养殖的各种水质调控及预防，专家会给出更合理有效的建议… …
