Culture techniques of red insects

Red worms are Chironomus larvae, which are widely distributed in all kinds of water bodies, and their biomass often accounts for 50% to 90% of the total benthos in the water. it is an excellent natural bait for a variety of economic aquatic animals such as common carp, crucian carp, dace, Sturgeon, herring, rice field eel, Loach, river crab, soft-shelled turtle, turtle and so on.

Collection method of red worm

Red worms like to live in fat water where the current is slow, and the water depth is generally 0. About 5 meters. In late spring and early autumn every year, there is a large number of red insects breeding season. Red insects float on the surface of the water, often making the surface of the water brown-red, which is easy to find. Red worms can be collected all the year round in the south of China, and it is easier to be collected in spring and autumn.

1. Before collection

To prepare the collection net, the handle should be long, 3mur4 meters is suitable, the caliber is small, 20mur30cm is suitable, and the net depth is 50Mel 60cm is the best. Also cover the net mouth with a layer of plastic green gauze, the green gauze mesh just so that the red worm can pass through. In this way, when collecting, it can prevent water plants and other sundries from entering the net.

2. Collection method

First select the appropriate collection site, find the red worm, use the collection net to catch slowly and repeatedly on the water surface. After repeating this several times, a large number of red worms can be caught and moved into plastic buckets or plastic food bags containing a small amount of water.

After picking red worms from the river, they should be put in a larger glass jar. Some water and green algae brought back from the river, such as sponges, should be put in the tank to increase the oxygen in the water, and some minced meat made from earthworms, locusts or other animals should be used as bait for red insects. When the number of red insects increases, it should be harvested and dried in time. In late autumn and winter, the fecundity of water fleas is greatly weakened.

When there is no water flea activity in the tank in winter, do not pour out the water in the tank, because they are lurking in the green algae. We can put the water tank near the sunny room or radiator. In the spring, when the indoor temperature rises, the red worm comes out again. When the room temperature rose to more than 28 ℃, the red worm began to multiply in large numbers.

Culture method of red worm

1. Red insects like to live in fat water with slow currents. Late spring and early autumn every year is the season for red insects to multiply in large numbers. They float on the surface of the water and often make the water brown and red. This is an excellent opportunity for us to collect red insects.

2. When raising a small number of red worms in the family, the river pond sludge can be taken back together with the red insects and placed in pots or glassware, preferably soaked in river water. if you breed with tap water, you should bask in the tap water for 2 to 3 days in advance and go out to bleach and other substances. Change the water every other day. To prevent frost in winter, put wet red cloth strips on utensils to moisturize.

3. It is most suitable to use a container with a large area of contact with the air, because the red worms will float to the surface to have similar breathing movements, so if there are a large number of them, they are afraid that they will not be able to compete for a place and die.

4. The light source is necessary for raising red insects. The light source can not be turned off at night, but can be illuminated by a small light source (such as a 5w night light, etc.) at night. Because the red worm is too lazy to breathe, if there is no light source, it is easy to die the next day.

5, there are specialized farms, most of them use rice bran, saw, incense coke, bagasse, silt, pigeon dung and so on to make breeding feed after fermentation. When raising red worms at home, you can use yeast powder to soak in water to feed, but the dosage must be controlled.

6. When the number of red insects increases, they should be harvested in time and dried in the sun. In late autumn and winter, the fecundity of red insects is greatly weakened. In winter, when the red worms are not visible in the tank, do not pour out the water in the tank, because they are lurking in the green algae. We can put the water tank near the sunny room or radiator. In the spring, when the indoor temperature rises, the red worm comes out again. When the room temperature rose to more than 28 ℃, the red worm began to multiply in large numbers.
