How does the freshwater pond breeding in aquaculture? – Aquatic Forum – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website
Freshwater pond breeding.
(1) In the low-temperature rain and snow, the pond should increase the water storage, improve the insulation capacity, and generally require water depth to be more than 2 meters. If you have condition, you can extract groundwater, or introduce ground hot water or factory waste hot water, improve the water temperature of the pond;
(2) There is a frozen sealing pool in the pond, and it is necessary to perform artificial ice and oxygen, ensure more than 1/3 or more area. Contact with atmosphere, prevent fish hypoxia and suffocation;
(3) Chinese sturgeons should avoid temporary water in low-temperature rain and snow, so as not to cause frostbite, frost and other phenomena.
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).
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 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 produces preservation agents are very simple, a bottle 100 milliliter stock, after 1 L of water dilute, directly throw it into the tragedy of the water body, and in the truth, the more the original liquid is put on, the better the seafood product is not bad. 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.
