Can it still be eaten after it dies?

A dead Asian swamp eel cannot be eaten. Although it is highly nutritious, it must be fresh and alive to be eaten, and a dead Asian swamp eel must never be eaten. This is because the protein structure of the Asian swamp eel contains a great deal of histidine. Once the Asian swamp eel dies, its protein structure breaks down rapidly; bacteria seize the opportunity to invade, and the histidine is quickly converted into histamine, a toxic substance, which causes poisoning in people who eat it. A live Asian swamp eel, however, contains no "histamine" - this is because the Asian swamp eel is vigorous and bacteria cannot destroy the protein of its body.

Who should not eat it?

1. Patients with bronchial asthma, because the Asian swamp eel contains a relatively high protein content; eating it brings no benefit to patients with bronchial asthma, and instead causes a certain degree of harm to their bodies.

2. Patients suffering from lymph node tuberculosis should certainly not eat the Asian swamp eel, and those who are themselves allergic to eel should not eat it either.

3. Patients with pruritic skin diseases are also among those not suited to eating the Asian swamp eel, because the Asian swamp eel can be described as a "stimulating food"; after eating it, patients will only worsen their condition, and their recovery will not improve. This is not the result patients hope to see, since every patient hopes to recover quickly, as the torment of illness is not so easy to endure.

Farming benefit analysis:

1. First, pond renovation plus infrastructure construction costs about 500 yuan per mu, including pushing the pond, building up the pond banks, installing water inlet and drainage pipes, as well as escape-prevention nets, bird nets, etc. These are all essential conditions for loach farming.

2. Next is the cost of fry: 60,000 to 80,000 loach inch-fry are stocked per mu, costing 3,000 to 4,000 yuan, plus some silver carp and bighead carp to regulate and stabilize water quality, costing 500 yuan.

3. Feed and medicine costs: loach farming mainly feeds artificial compound feed, 2-3 times a day, with the feeding amount at about 3% of body weight, feeding small amounts more frequently; at ordinary times, pay attention to regular disinfection and improving the substrate, and at peak feeding periods Chinese herbal medicine or allicin can be added to prevent disease. Feed and medication costs total 6,000 yuan per mu.

4. Miscellaneous expenses, electricity, labor and related costs total 1,000 yuan.

All the above loach farming costs total 12,000 yuan per mu.

Farming benefits: the loach yield per mu is about 2,000 jin, with an average output value of 16,000; after deducting costs, the profit from loach farming reaches 4,000 yuan per mu. But everyone should be reminded that the current market price of finished loach fluctuates greatly, and with the national farming total tending toward saturation, it is recommended that everyone not blindly follow the trend. Farming carries risk, and only by handling every farming detail well can final success be achieved
