1. aquaculture facilities: prepare aquaculture ponds, insect nets and aerobic facilities. Aquaculture ponds should be built together with aquatic and terrestrial circles. The aquatic circle should be built with pebbles or stones in the water, and the terrestrial circle can be piled with river sand and pebbles in one corner of the aquaculture pond to form an inclined plane.

2. Feeding: Put the prepared fry into a culture pond with suitable water temperature and salinity, and the stocking density is generally 50- 100 fish per square meter.

3. Daily management: Feed Tenebrio molitor and other bait evenly around the culture pond every evening, and pay attention to changing water and removing food residues every day.

I. Breeding facilities

1, culture pond

Centipede is an aquatic breeding insect, which moves near the water every day, but it can also survive on the shore. When building an aquaculture pond, there should be an aquatic circle and a terrestrial circle. The hydrosphere is made of pebbles or stones in the water, generally 2m? The culture pond adopts 5m cement pond with a depth of about1m.. The bottom of the pond is paved with river sand and flat pebbles, and a drainage pipe is set with a depth of about 0.5m A slope is filled with river sand and pebbles at a corner of the aquaculture pond with a gradient of 45? The height is 1m, and the bottom area should not exceed 1/4 of the bottom of the pond.

2. Insect net

The size of the insect net is the same as that of the aquaculture pond. The steel pipe frame is fixed on the cement pool, and then a sewn insect-proof net is laid on it, and the entrance and exit are usually sewn with zippers.

3. Aerobic facilities

The water source in the culture pond is not circulating, and the centipede consumes a lot of oxygen, so it is necessary to prepare some oxygen-increasing equipment according to the situation. Generally, each aquaculture pond can be equipped with an aerator to keep the dissolved oxygen in the pond above 6 mg/L.

Second, feeding

1, stocking

Before the prepared centipede worms are put into the culture pond, the water temperature and salinity should be adjusted so that the temperature difference is within 2℃ and the salinity difference is within 5%. Don't feed it in a hurry after putting it in, wait for a few hours, let it adapt to the environment first and find its own habitat.

2. Density

The stocking density of fry is generally 50- 100 per square meter. In order to promote the growth of worms, it is necessary to screen and isolate them in time according to their size in the feeding process. Generally, centipedes in the younger stage should be kept separately to avoid being eaten by older insects.

Third, the daily management

1, bait feeding

Water centipede is quiet during the day, and it is the peak time of eating at night, so it can be fed in small quantities during the day. Usually, Tenebrio molitor can be fed evenly around the culture pond every evening, and the amount of Tenebrio molitor fed every day is about 65,438+00% of the total amount of centipede. Artificial farming mainly uses Tenebrio molitor, fish bait and river shrimp as bait, and the feed must be fresh, free from pathogenic organisms and toxic and harmful substances.

2. Water quality management

The water level of water centipede culture does not need to be too high, and it is generally enough to maintain the water depth of 40-60cm. Generally, the water is changed once every three days, which is beneficial to the growth of insects. Check the water quality regularly every day, because the water quality of centipede life deteriorates rapidly, especially if it is not circulated. In addition, adjust the pool water with quicklime water regularly or irregularly.

Step 3 feed daily

Clean up food residues in time every day, otherwise the residues will easily pollute the water quality after rotting. The next morning after feeding, the centipede needs to pull out the drain pipe for drainage after eating the remaining bait at the bottom of the pond, and wrap the drain pipe at one end of the pond with small mesh gauze in advance.
