Application-of-sodium-humate-in-aquaculture

Application of sodium humate in aquaculture,Sodium humate is generally obtained by extraction of weathered coal slurry through a sodium hydroxide solution. Non-toxic, odorless, non-corrosive, soluble in water. Medically used to stop bleeding and diarrhea. Its molecular structure is complex and has many functional groups.

In addition, it is a polymer organic compound, which has strong adsorption, exchange, and comprehensive capabilities, and is widely used in industry. In agricultural aquaculture, the so-called feed additives, synergists, environmental modifiers, etc. can be changed.

The content of sodium humate dry base in sodium humate is generally more than 75%, which is a good veterinary drug and feed additive for producing green milk and egg food.

Water and water purification

Utilizing the comprehensive adsorption characteristics of sodium humate, it can assist in the treatment of turbidity, pan-bottom, dead algae, oil film, foam and other water quality conditions.

Application of sodium humate in fish production

Sodium humate can improve the utilization rate of aquatic animal feed, promote animal growth, enhance the body’s resistance, reduce morbidity and mortality, especially for improving the anti-stress ability of fish overwintering and long-distance transportation.

Tests have shown that there are many uses of sodium humate, which can be used to soak fish species or to be added to bait. Chang Shun (2002) reported that in the process of transporting live fish, the use of 0.002% sodium humate in the transport water body can purify the water and improve the transport survival rate.

Simple and easy to use, the effect is very good. At the same time, it also plays the role of the medicated bath fish body, and does not produce any poisonous or side effects on the fish; using it to feed the fish for a long time can reduce the feed coefficient by 8% to 12% and increase the yield by 10% to 15%.

The product fish is strong, the epidermis is rich in mucus, and the meat tastes delicious like a river fish. In a sense, it is also a green food.

The Animal Husbandry and Fisheries Bureau of Haidian District of Beijing tried to use a 0.1% to 0.3% sodium humate solution to soak the fish species injured in 2000 shipments for 30 minutes. After 7 to 10 days, the wounds healed and all the fish species survived.

In 2000 injured fish species that were not treated with sodium humate, the wound recovered slowly and 150 deaths occurred within a week.

The sodium humate is formulated into a disinfectant solution of 300×10-6~400×10-6, and the fish species are soaked for 5 minutes, which has special preventive effects on common diseases such as water mold and enteritis. In the use of fish feed, the feed conversion rate can be increased by 8% to 13%, the winter mortality rate is reduced by more than 10%, and the long-distance transport mortality rate is significantly reduced.
