1. How to raise earthworms to feed fish?

Earthworms can be used to feed fish, and they are good fish food. But earthworms grow in unclean places. They carry a lot of bacteria and viruses, so they cannot be used to feed fish directly. Because the fish we raise are ornamental fish, they are relatively delicate. If they are fed directly, it is easy to cause the fish to get sick and have indigestion. (Commonly known as rotten intestines) The best way is: take the earthworms back and don't feed them anything, let them excrete the soil and mud in their stomachs. Then soak them in salt water, wash them and chop them into small pieces before feeding them. This is what I did when fish food was scarce, and the fish turned out much prettier than those fed with grains.

2. What are the advantages and disadvantages of raising fish with earthworms?

Earthworms can be fed directly to fish. They are rich in protein, a full range of amino acids, vitamins, calcium, etc. In addition, earthworm meat can emit a special smell, which can easily attract and stimulate the appetite of fish.

Therefore, adding a certain amount of fresh earthworms to fish feed can make high-quality and efficient feed, thereby improving the utilization rate of the feed and improving the fish's palatability and feeding intensity of the feed.

The downside is that it is expensive and may make the fish picky eaters.

3. What are the advantages and disadvantages of feeding fish with earthworms?

Many benefits

Healthy eating

First of all, earthworms are native mollusks and contain high protein. They are good for fish nutrition. Secondly, earthworms can be found in almost any soil. They are cheap. The disadvantage is that if they are fed alone, they will lack other nutrients, causing malnutrition in fish. Only a reasonable nutritional combination can make fish grow healthily. Feeding with a variety of fish feeds is the best.

4. Is it cost-effective to raise earthworms to raise fish?

It is not cost-effective to raise earthworms to raise fish. The cost is too high. Just use grain or feed.

5. Is it good to feed fish with dried earthworms?

Feed the fish well

Earthworms are rich in protein and have a relatively comprehensive nutritional composition. When used as an additive feed for fish farming, the feeding effect is equivalent to or exceeds that of Peruvian fish meal, making it an excellent protein feed.

Mixing dried earthworms in compound feed for fish farming is inferior to natural bait in terms of palatability and feed efficiency. However, using dried earthworms mixed in various dry compound feeds for fish farming can improve and make up for this shortcoming. Fish are particularly fond of eating it, especially for fry over 3 cm in length. The method is to mix dried earthworms into various dry compound feeds, so that the body fluids of fresh earthworms are absorbed into the various mixed raw materials, which has a high feed efficiency for fish and is better than other compound feeds for fish farming.

6. What are the costs and benefits of earthworm fish farming?

(1) Cost of earthworm farming

1. Use 100 cubic meters of bait (cow dung, pig dung, chicken dung, and mushroom waste) at 20 yuan per cubic meter, totaling 2,000 yuan.

4. Plumbing and electrical tools cost RMB 500.

Total cost: 5,100 yuan.

1. Earthworms: Generally, the annual yield of fresh earthworms per mu is 2 to 3 tons, and up to 5 tons. Based on the minimum of 2 tons, the current market price is more than 10,000 yuan per ton (it can be sold as bait for more than 30,000 yuan per ton). Based on the minimum of 10,000 yuan per ton, the income can reach 20,000 yuan.

2. Earthworm manure: 40 tons of earthworm manure at 150 yuan per ton, totaling 6,000 yuan.

Total income: 26,000 yuan.

(III) Profits from earthworm farming

26000-5100=20900 yuan. If you hire workers to carry out large-scale breeding, you also need to pay the workers' wages. Generally, one worker can manage two mu of earthworm breeding. Based on a monthly salary of 1000 yuan, the salary per mu needs to be paid about 6000 yuan, and the actual profit is about 15000 yuan.
