A Complete Analysis of Ammonia Nitrogen Sources and Degradation Methods in Aquaculture
What is ammonia nitrogen? Ammonia nitrogen refers to the combination of nitrogen present as free ammonia and ammonium ions in water. It is the main factor causing major toxicity to aquatic organisms. However, ammonium ions are not toxic. 1. Sources of ammonia nitrogen. There are four main sources of ammonia nitrogen: first, sludge. The deeper the pond sludge, the more, as temperature rises, large amounts of organic matter ferment and produce ammonia nitrogen; second, feed. After feed is digested by aquatic animals, feces and urine are excreted, producing large amounts of ammonia nitrogen. Next, residual bait is transformed by anaerobic bacteria into peptides and amino acids, and then into molecular ammonia and ammonium ion substances; third, fertilizers. Such as organic fertilizer, urea, nitrogen fertilizer, compound fertilizer, etc., are all foundations for producing ammonia nitrogen; fourth, various dead grasses and algae, which are converted into ammonia nitrogen under the action of anaerobic bacteria. 2. Ammonia nitrogen degradation. First, natural consumption. 1. Through nitrifying bacteria living in the oxygen in the water body, ammonia is converted into nitrite, and then converted by a second type of nitrifying bacteria into nitrate. Nitrate is a non-toxic substance and is converted by anaerobic bacteria into nitrogen gas, which rises and is released; 2. Algae and microorganisms. Ammonia nitrogen is also a eutrophic fertilizer. The more algae and microorganisms there are, the stronger their ability to absorb ammonia nitrogen, and the faster the ammonia nitrogen content is reduced; 3. Aquatic plants, such as water hyacinth, alligator weed, lotus root and other aquatic plants. Among them, water hyacinth has a particularly strong ability to consume ammonia nitrogen. One water hyacinth plant with 10 branches can consume the ammonia nitrogen excreted by 8 people in 24 hours. Second, artificial degradation. 1. Clean out sludge and use coke slag landfill for adsorption; 2. Control stocking density and feed bait reasonably; 3. Regularly use photosynthetic bacteria and lactic acid bacteria as well as organic acids and sodium humate for nitrifying degradation; 4. Add and change water and increase oxygen, and control and regulate water quality well. When molecular ammonia in the water body exceeds the standard, the oxygen-carrying capacity of the gill fluid of aquatic animals will decline, damaging the epidermal tissue of the gills, leading to poor oxygen exchange in the blood, and at the same time poisoning will occur. Its manifestations include damage to internal organs such as the liver, pancreas, and stomach, swelling of the gastrointestinal tract, infection after mucosal damage, secretion of large amounts of mucus, causing difficulty breathing and leading to death. Ammonia nitrogen is the number one killer of aquatic animals, and it is also the most difficult problem for aquaculture personnel to grasp and solve. Prevention and control must be carried out from the very beginning, with regular testing, and strict prevention of serious exceedances and long-term exceedances, so as to ensure the healthy and normal growth of aquatic animals.

When fertilizing potatoes, the ratio of nitrogen, phosphorus and potassium should be appropriate
Potatoes have an equally important demand for nitrogen, phosphorus and potassium. In the process of yield formation, nitrogen supply is the foundation, ensuring the formation of sufficient green leaf area for photosynthesis; phosphorus supply is also indispensable for tuber formation and starch accumulation; on the basis of sufficient nitrogen and phosphorus, potassium supply is essential for carbohydrate assimilation in the early stage and for the later transport from above ground to underground tubers and starch accumulation. Field tests show that the absorption ratio of nitrogen, phosphorus and potassium by potatoes is about 1:0.5:2.5. In response to this demand

How to rescue pond fish after ammonia-nitrogen poisoning?
When carp, grass carp, bream, white pomfret, crucian carp, etc. are fed with pelleted feed, because the feeding amount is large, excrement and leftover feed increase, and the nitrogenous substances produced by protein decomposition increase accordingly. If even slightly careless, these fish will suffer ammonia-nitrogen poisoning, which at best affects normal growth and at worst causes the death of the fish. The identification and rescue methods for ammonia-nitrogen poisoning in pond fish are described below. I. Identification of poisoning 1. Occurrence characteristics. Ammonia-nitrogen poisoning has no distinction of season, morning or evening, or good or bad weather, and is mostly seen in adult fish
