What are the causes of deficiencies in aquaculture? – Aquatic Forum – China Animal Husbandry Website – A useful animal husbandry website
Causes of inadequate hydraulic oxygen:
2, aquaculture water hyperplaty
3, water body bacteria to decompose organics, resulting in oxygen consumption
4, The water body has an increase in water, and the oxygen decreases
5, the reductive substance in water, such as hydrogen sulfide, ammonia, nitrite, etc., its oxidation can also cause dissolution to decrease.
Water maintains sufficient dissolved oxygen, which can inhibit chemical reactions to which toxic substances, reduce chemicals such as ammonia, nitrite and hydrogen sulfide, and can be decomposed into non-toxic substances.
Fish shrimp, adaptation of water dissolved oxygen sample (mg / L), suitable scope, began to fall asphyxia death squid 5 ~ 81.50.3 squid 4 ~ 51.00.1 squid 4 ~ 81.550.4 鲮 4 ~ 81.60.5 Grassfish 5 ~ 81.60.5 Blue Fish 51.60.6 Texture 5.5 ~ 81.70.6 Baiyi 5.5 ~ 81.750.6 Robish 6 ~ 91.50.2 Dago Squid 5 ~ 81.40.7 Long Kiss 5 ~ 72.81. 5 Japanese 鳗 4 ~ 91.40.6 European 5 ~ 7 – squid 5 ~ 81.80.7 China prawns 6 ~ 81.40.4 虾虾 5 ~ 81.20.3 Roche Maimi 7 ~ 91.50 .5 river crab> 52.51.5
pond treatment: 1 week before the pond is released, 100 ~ 300 times the dilution of the biological EM bacteria with the dilution of the biological EM bacteria, the bio-EM bacteria. Insecticide, instead of lime, bleaching powder, etc., is used to disinfect and purify it. 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.
Burewery Add: According to 0.2% of the amount, evenly spray it on the baitSports feeding.
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 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.
Specifications: Cuome Island Biological Preservation Life: 138 yuan / bottle · 100 ml, 2190 yuan / bottle · 500 ml, 3380 yuan / barrel · 1 liter
logistics: 24 hours after order, National shipping (except remote areas and Hong Kong, Macao and Taiwan)
