Water quality management parameters must be known: Dissolved Oxygen – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website

Liaoning aquaculture must know the water quality management parameters: dissolved oxygen: in 24 hours, 16 hours must be greater than 5mg / L, the rest will not be less than 3mg / L, for the survival of the salmon perched freeze period Do not be less than 4mg / L. The oxygen is higher than 12 mg / L, indicating that oxygen in water has excess, and fish shrimp is easily bubble.

Symptoms: The high and low of dissolved oxygen in the water has a direct effect on the survival and development of fish. When the oxygen is less than 1 mg / L (mg / L), the fish will float If it is not taken by oxygenation, it will cause fish asphyxia, and it also creates favorable conditions to develop favorable conditions and reduce the disease resistance of the fish causes fish disease; sufficient oxygen can inhibit chemical reaction to generate toxic substances, transformation Or reduce the content of toxic substances (such as ammonia nitrogen, nitrite, hydrogen sulfide), while also improving the bait conversion is important for breeding.
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 the green island seafood produce preservation agent, spray water products for water products every 1-2 days, extend the freshness of the water products, keep the surfaceluster.
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 enhance the activity and quality of life of seafood, which can reduce their mortality in the process, extend the time of life! It is because the Green Island Biological Soldering 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 the stock solution, can be used for 10 tons of water (ie 10 cubic meters of water), 100 m7 green island seafood, aquatic yield, bio-preservation agent, 1 liter (2 kg) Water is diluted, 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.
