How to correctly use the dichondria in eel farming

The correct method of using glutaraldehyde in eel farming: the glutaraldehyde on the market is basically acidic fortified glutaraldehyde for long-term preservation, with a reinforcing agent (or activator, sodium bicarbonate) and a corrosion inhibitor (sodium nitrite).

1 Suggested dosage: Add 5ml of glutaraldehyde solution per 200L of water. Use twice a day for 3 to 4 days, if it doesn't work, double the dosage (10 ml 200 L) until it reaches 4 times the recommended dosage (20 ml 200 L).

2. When adding, it is directly added to the tank water, without filtration. It is recommended to use it 1 hour after turning on the light to 2 hours before turning it off. Oxygenation and liquid fertilizer had no effect on the effect of glutaraldehyde.

3) If the effect of adding the whole tank is not obvious, you can use a syringe to add it locally near the algae. The effect is obvious. However, this method should be used with caution for some aquatic weeds (see below for details).

4) Glutaraldehyde is most effective against Hailanchoderma. Usually after 3 to 4 days of use, the black hairweed will turn red and then die.

5) The role of filamentous algae, brown algae, and green spot algae is controversial. There are examples of both success and failure, and most of the successful examples are topical application, or large dose application of the whole tank (not less than 4 times the recommended value).

6) The inhibitory effect on algae regeneration was obvious.

7) It is generally reflected that Staghorn moss is sensitive to glutaraldehyde, which is easy to cause yellowing and death. There is controversy about the effect of glutaraldehyde on moss, anchovy, staghorn iron crown, etc., and it is not recommended to add glutaraldehyde locally in its vicinity.

You glutaraldehyde bought it for more money.

Hello, eel farming, need better feed - extruded material 1, good water resistance, reduce feed nutrient loss puffed pellets have a certain water resistance, not easy to be lost to the water body. It has little pollution to the water body and reduces the cost of tailwater treatment. The amount of water exchange for breeding is greatly reduced, which is convenient for site selection and construction, resource protection, and reduction of breeding costs.

2. High temperature treatment to improve the safety of feed The puffed pellet material is ripened by high temperature treatment, which is conducive to the digestion and absorption of eels, and can also kill the harmful bacteria carried in the raw materials, such as: Salmonella, Escherichia coli, Staphylococcus aureus and other harmful bacteria. 3. Balanced nutrition, improve the feed rate, and the expanded material is matured and granulated at high temperature, which makes the fish body easier to digest and absorb, reduce the load on the liver, and reduce the rate of enteritis.

Animal fat, dietary fiber, immune factors and other nutrients are added to the extruded material to make the nutrition more balanced, the fish body is healthier and the growth is more efficient. At the same time, the feeding of extruded material makes the eel feeding rate more stable in the high temperature season, and the feed conversion rate (feed rate) is increased by more than 5%, which effectively reduces the breeding cost and improves the breeding efficiency. 4. Simple feeding, uniform growth of puffed material feeding method is simple and fast, according to the feeding situation can be directly dry sprinkling puffed material.

The extruded material floats and spreads on the surface of the water body, increasing the feeding area of the eel, and the eel with weak constitution can also grab the feed, grow more evenly and reduce polarization.

Eel, alias: white eel, white eel, river eel, eel, blue eel, wind man, Japanese eel. Eel is a general term for species that belong to the order Eel.

Also known as the eel, it is a fish that resembles a long serpentine in appearance and has the basic characteristics of a fish. In addition, eels, similar to salmon, have migratory properties. Eels are snake-like but scaleless fish that are generally found in brackish and freshwater waters.

Eels prefer to live in clean, unpolluted waters and are the purest water creatures in the world.
