What are the symptoms of nitrite poisoning in aquaculture? – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website
Nitrite is mainly respirated by fish and shrimp. In general, when the nitrite concentration in the water is 0.1 mg / L or less, the nitrite concentration is 0.1 mg. When / L, as the concentration increases, the number of fish and shrimp red blood cells and the number of hemoglobin gradually decreases, and the blood carrier oxygen capacity is gradually reduced, and tissue hypoxia occurs. At this time, fish shrimp is reduced, and there is a lesion in the sputum, difficulty breathing, uneasiness or slow response, loss of balance, lateral lying, at this time, if the anatomy of fish will find fish blood, black purple or red brown, or even change due to change The membrane permeability of the internal organs, penetration regulation is disordered, causing congestive symptoms similar to bleeding, is generally referred to as “brown blood disease”, nitrite to shrimp, and crab is more poisonous, mainly to the liver Damage, shrimp, crab poisoning, damaged black, and finally died.
The currently used microorganisms mainly have a variety of photosynthetic bacteria, Bacillus, EM bacteria, lactic acid bacteria, and amplifier, and the different bacteria and the above microorganisms are: nitrifying bacteria. It is possible to absorb the high concentration of nitrite in water, convert it into a nitrate, nitrogen, and other harmless substances, and the above microorganism does not have such degradation. Their role mechanism is mainly to repair water microecological environments, improve water quality and substrates, indirectly increase the water dissolved oxygen, ensure nitrification, and nitrification normal circulation. With this awareness, we should go out of photosynthetic bacteria, Bacillus, and EM bacteria to degrade the misunderstandings of nitrite, which acts only to improve the environment, repair the water microecological environment. We can use its daily management measures to prevent nitrite.
When the moisture nitrite concentration is above 0.5 mg / liter, it is not advisable to use the above microorganisms, in particular by Bacillus, in a short period of time, in a short period of time. In response to the case, we should take quick effects to reduce the nitrite concentration to the horizontal level of the breeding animal, and then consider using the above microorganisms.
Prevent measures to prevent nitrite concentration: 1 Keep the seedlings or breeding ponds long-term non-hypoxia, rationally use the oxygen generators and appropriate amount of feeding; 2 Conditional pond, regularly change the new water; 3 regular sprinkles Safety, efficient, non-toxic side effects of disinfectants, chlorinated dioxide formulations, oxidation of nitrite, reduce toxicity; 4 regularly splashing microbial waterBright agents, decompose nitrite, remove toxicity, improve water neutralization factors, thereby reducing the occurrence of diseases, and improving the survival rate of farming varieties.
Cuine Island Ammonia Nitrogen Defluement Fungi Nitrofiltered Societium Treatment Water Take A Water Take A Purification Agent, composed of nearly 100 microbial flora in Photosynthetic flora, lactic acid flora, yeast group. It is a microbial bacteria made of a suitable ratio and a fermentation process. It is possible to speed up the decomposition rate of various organic matter in water, effectively decompose, degrade organic matter in sewage, and decompose it into natural substances soluble in water.
Pond Treatment: 1 week before the pond is released, the anti-secting liquid made from the dilution of the biological EM bacteria with 100 ~ 300 times, the chemicals of the biological EM bacteria, which is used for the antibiotic fluid, which is used in the antibiotic fluid, which is used in the antibiotic fluid. Equisounces, sprayed the pond, used to disinfect and purify them. 2.5 liters per acre of water.
Water quality purification: 3 to 10 days prior to stocking, the dilution of the biological EM bacteria with a bio-EM bacteria in the presument. Depending on the water quality, starting 15 days, after a month, the water quality is poor, properly shortening the sprinkle time. It is used in a 15-acre surface (1.5 meters or less).
Pond binder fermentation: According to the pond base, Cui Gome Island Aquaculture Bioengiostera, brown sugar = 500: 1: 1, adding appropriate water, mixing accumulation of 7-14 days.
Take the bait Add: According to 0.2% of the amount, evenly spray it on the bait.
Treatment of animal bait: When feeding fresh animal bait, stir well according to 0.1%.
Disinfection: Decoction of the cultivation tool such as the cultivation tool such as the cultivation tool and fishing nets with 200-500 Double Emperor’s aquaculture.
Aquatic products preservation: use 10 times Cui Island seafood produced fresh living agent, spray aqueous water in the water product every 1-2 days, extend the freshness of the aquatic product, and keep the meter luster.
Cuverong Island Biotechnology is recommended from Japan’s Cui Green Island Seafood Production Preservative, which is made of photorated flora, lactic acid flora, yeast group, Gram-positive amplifier flora, fermentation 5 major categories of flora, more than 80 kinds of beneficial microorganisms. The collection of these genus active principles constitute the principle of the function of the product.
Cuver Island Biological Seafood Generation Preservatives, improves the activity of aquatic product! It can improve the activity and quality of life of seafood, which can reduce their mortality in the processes, extend the time of life! This is because Cuver Island Biological Preservative is a Japanese imported stock solution, a bottle of 100 ml of stock can handle 10 tons of water, and the microorganisms are more likely to survive.
Seafood produced preservation agent is very simple, a bottle of 100 ml of stock solution, after 1 L of water dilute, directly throwing into the tragedy water body and mix well, in the truth, the more the stock solution is put on Ok, there is no bad impact on seafood products. But invested more, it will cause traumatic costs. Therefore, there is also a good cost-effective question when used.
100 ml of this stock solution, can be used for 10 tons of water (ie 10 cubic meters of water), 100 m7 green island seafood aquatic products temporary biological preservation agent with 1 liter ( 2 kg) water dilute, can handle 10 tons of water (ie 10 cubic meters of water), one ton of water treatment costs are only 3.8 yuan, which is much cheaper than the price of aquatic preservation products on the market.
