Yellow cockroach breeding method. How to raise yellow cockroaches at home

Raising yellow cockroaches at home can start from preparing fish tanks, selecting water quality, putting yellow eels, feeding reasonably, and controlling water temperature.

1. Prepare the fish tank.

To raise eels at home, choose an appropriately sized fish tank, preferably with a filter and heater, to keep the water clean and the temperature stable. Yellow cockroaches need a spacious living space, so the branch or size of the fish tank should be at least 10 liters.

2. Select water quality.

Yellow cockroaches need clean, clear water, so change the water regularly and keep the water quality stable, either by using water treatment agents to remove harmful substances, or by adding aquatic weeds and algae to help maintain water quality.

3. Put in the yellow eel.

Before putting yellow eel fry, make the fish tank smoother, so as not to bruise the body of the yellow eel, and the yellow eel fry is also best soaked in salt water for 5-10 minutes, and it is best to put the yellow eel fry about per square meter.

4. Reasonable feeding.

Yellow cockroach is an omnivorous fish, you can provide them with bait, shrimp skin, vegetables and other food, feed 2-3 times a day, resistant to return and do not eat too much each time, to avoid polluting water quality.

5. Control the water temperature.

The suitable water temperature for yellow cockroaches is 20-25°C, too high or too low temperature will affect their growth and health, if you do not grasp the change of Chang hunger temperature, you can use a heater to keep the water temperature stable.

Take a 10-square-meter pond as an example to estimate the economic benefits of eel farming.

1. The cost of building a pool is 200 yuan.

2. The purchase of 15-20 kg of wild yellow eel, based on the summer medium size (30 50 grams) yellow eel 15-20 yuan per kilogram, the cost is about 300-400 yuan.

3, after 5 8 months of feeding, the weight of the eel can increase by 3 5 times, we calculate the weight gain of 3 times, then 20 kg of the eel can gain 60 kg, according to the feed cost of 8 yuan per 1 kg of yellow eel (in fact, a large number of flies, maggots, earthworms, etc. are not so much), it will cost 480 yuan of feed costs.

4. 100 yuan for drugs and other expenses. The total cost of the above 4 items is about 1080-1180 yuan.

The obtained is 80 kg of large-size yellow eel (weighing more than 100 grams), and calculated according to the medium-sized ** (40 yuan per kilogram) of large-size yellow eel purchased in the winter and spring market, it can earn 3,200 yuan, and the input-output ratio is about 1:1.

The cost of yellow eel breeding is mainly composed of the following factors: 1, what kind of breeding yellow eel cage pond culture or cement pond culture, if the cage culture of a 6 square cage is about 50 pieces, a 10 square cement pond is about 800. 2. The cost of purchasing food seedlings If the yellow eel is listed in large quantities, it is about 8-10 yuan per catty, and when the amount of yellow eel is small, it is 10-12 yuan, which is also priced according to the local **.

3. Control the breeding feed If it is a self-breeding earthworm and fly maggot, the cost is relatively low, and if it is to buy feed, it will be more expensive. 4. The size of the breeding area is different The large breeding area of the yellow eel is more than the seedlings, the cost of building a pond is high, and the feed is also used, so the cost is naturally high. At the same time, you also have to bear a certain amount of risk, and the specific cost should be calculated according to local conditions.

The differences are as follows:

1. Wild yellow eels live in rivers or ponds to build a home, they must dig a deep hole, so deep that they can survive in dry weather, so the head of wild yellow eels is sharper than that of farmed yellow eels.

2. The tail of wild yellow eels is thin, long and pointed, and the tail of domestic yellow eels is thick and short, even flat and bald. The tail of the yellow eel, touch the tail of the wild yellow eel with your fingers, and the tail of the wild yellow eel will wrap around its fingers. This is not the case with farmed eels.

3. Color, the wild color is darker. taste, the wild muddy smell is heavier.

The fry are about centimeters long after 5 days of hatching and can enter the fingerling rearing. The breeding pond can be used in soil ponds, with an area of 1-2 acres, with a water depth of about one meter, a flat bottom, sufficient water sources, and convenient drainage and irrigation. After disinfection with 100 kg of quicklime per mu before seedling, 500 kg of fermented manure is applied per mu, or 1500 kg of green manure per mu is used to cultivate plankton, so that the fry have sufficient natural bait.

Fry are tested for toxicity before stocking, by trying to raise a small number of fry in small cages in ponds, and surviving for 30 hours before actually releasing them. Before stocking, 1-2 cooked egg yolk powder are fed for every 50,000 fry, and then put into the breeding pond at a density of 10-150,000 per mu after they are full. As the fry grow up to supplement the feed, you can continue to apply fermented manure to cultivate water color and sprinkle soybean milk in an appropriate amount, half a month later, when the fry grow to 3 cm, start to feed rice bran, wheat bran and other concentrate feed, the daily feeding amount is 15%-20% of the fish weight.

In the process of fish fry cultivation, it is necessary to pay attention to the adjustment of water quality, due to frequent fertilization and bait, manure residue bait is easy to spoil the water quality, so change one-third of the water every 2-3 days, and it is best to keep a slight flow of water. You can also put some daffodils and duckweed in the nursery pond to purify the water quality. When the fry grow to 3-5 cm, it is necessary to carry out the thinning and stocking of the net exercise, and the specifications of the fry in the same pond are as consistent as possible, and the general stocking density of 3-4 cm is 8-100,000 per mu, and 5-6 cm is stocked 5-60,000 per mu.

After 2-3 months of culture, it can grow into fingerlings of more than 6 cm, and then it can enter the grow-out stage. Pond culture of yellowtail carp is mostly with the domestic fish with breeding, about 200 per mu, the management method is the same as the fish, without increasing the feed can harvest about 80 kg of output. Yellowtail can also be reared in large water areas, and because they can reproduce on their own to form a natural population, they can have a long-term harvest after 2-3 years.
