The main uses of 4-Jiang-3-medicine turtle dace cover the following ends:
First, it is used as medicine. The turtle dace has the effect of nourishing yin and latent yang, which can treat the symptoms of yin deficiency and fever. Mortal people due to yin fluid deficiency, virtual fire endogenous, causing afternoon hot flashes, night sweats, etc., turtle dace can help nourish yin and reduce fire, calm the appearance of virtual heat. And it can soften and disperse, and there are diseases that accumulate in the body, such as liver and spleen enlargement, etc., and it also has the power of resolving and dissipating. There are many records in ancient medical books, such as the "Shennong Materia Medica", which mentioned the wonderful use of turtle dace in medicine. Later physicians often used it as medicine to treat syndrome differentiation and treatment, and repeatedly caused sinking diseases.
Second, the choice of dietary therapy. Its meat is fresh and tender, rich in nutrients, and can be used for dietary therapy. With turtle beetle and various ingredients, it is stewed into a soup, which tastes delicious and nourishing. If stewed with wolfberry and red dates, it can nourish blood and nourish yin, nourish the body, and is especially suitable for people with weak constitution and insufficient qi and blood. Regular consumption can strengthen the body and increase qi and blood.
Third, in the ecology, turtle beetle also has its important position. It is an aquatic organism. It feeds on algae and small aquatic organisms in the aquatic ecosystem, which can regulate the number of such organisms and maintain the balance of the aquatic ecosystem. And it is also a food source for other organisms, linking up the food chain and contributing to the stable operation of the entire ecology.

The production method of 4-Jiang-3-Shell mussels and turtles is also related to the skill of aquatic breeding. As recorded in "Tiangong Kaiwu", the production method of such aquatic products is quite unique.
Shell mussels, their reproduction often depends on the state of nature. In rivers, lakes and other waters, shell mussels mostly live in the bottom of the water and sediment. In spring, the water temperature gradually rises, and the shell mussels are also gradually active. The female mussels lay eggs in the body, while the male mussels excrete sperm in the water. The sperm and eggs meet and form larvae. The larvae are tiny, drifting with the water, waiting to be attached to suitable things, such as gravel, aquatic plants, etc., and gradually grow into mussels. And the land where the mussels are raised needs clean water, gentle water flow, and rich in organic matter, which is conducive to the growth and reproduction of the mussels.
As for turtles, the production method is also exquisite. Turtles are good to hide in the mud at the bottom of the river or in caves on the bank. Every time they are breeding, the female turtles go ashore at night, find a soft sand, dig holes and lay eggs in it. After giving birth, cover it with sand, and use the temperature of sunlight to incubate eggs. In order to raise turtles, it is necessary to choose a suitable place, which should have sufficient sunlight, suitable water temperature, and both water and land. There are many aquatic plants in the pond, which can be used as shade and habitat for turtles. Feeding food should be small fish, shrimp, snail meat, etc., to satisfy their carnivorous nature. It is necessary to pay attention to the water quality every day, and change the water frequently to keep it fresh, so that the turtle can grow healthily and multiply endlessly.
Therefore, the production of shell mussels and turtles emphasizes the nature, and according to their habits, prepare a suitable environment to achieve good results.

4 - - 3 - The price range of Tamarind Clam Shrimp in the market is unknown in ancient times. However, considering the changing situation of the city in the past and the change of the abundance of products, it may be slightly deduced.
In the land of water, the prosperity of its aquatic products has always been one side of the country. 4 - - 3 - Tamarind Clam Shrimp, born and raised in this place, its price should change from time to time, depending on the thinness of the thing.
If the weather is smooth and the waters are open, the genus of this shrimp clam is prosperous, and in the city, there is a sufficient supply. At that time, the price was relatively flat, and with the strength of ordinary people, holding a few copper coins, it was easy to get two. Because of the abundance of products, merchants competed to sell, and the price was difficult to be high.
On the contrary, in case of floods and droughts, or when the weather is surly, the production of shrimp and clams decreases sharply, and the circulation in the market is rare. At this time, there are many people who ask for it, but there are few people who supply it, and the price will rise. I am afraid that it is not possible to get several times the usual price, or even if there is no market for it, it is difficult to find one of the thousands of gold.
Where there is a market, the price is also affected by various factors. If the transportation and sales of traders are far and near, if the self-produced land is lost to the city, and there is no transit cost, the price may be slightly cheaper; if the number of places is moved, plus the consumption of storage and the profit of business travel, the price will increase. And in different cities, the supply and demand are different. In the places where rich families live in the city, the taste of fresh food is good. Although the price is high, there are many people competing for buyers; in remote towns and small towns, people often eat coarse food, and the demand for shrimp and clams is small, and the price is difficult to be high.
To sum up, the price of 4-3-3-mandarin clam shrimp in the market is parity in good times, and it is easy to count two copper coins when it is about a few dollars; when it is sorry, it may be several times higher than usual, or even the price is not in the market. It is difficult to determine the exact number, due to changes in weather, geographical conditions, and supply and demand.

In "Tiangong Kaiwu", the third of the river fish, the fish shell, the conditions for its existence are quite exquisite.

The fish like living water, so it needs to be constantly changed to keep the water clear and flowing, so that it can meet its nature. If placed in stagnant water, the fish will die soon. And it also has requirements for water temperature, neither too cold nor too hot. If the water temperature is cold, the fish body will be stiff, the activity will be slow, and the life will be dire for a long time; if the water temperature is hot, the fish will be easily infected and difficult to survive. It is appropriate to use room temperature water, about twenty degrees is better.
Those who have a fish, they should be stored in the stone, in a damp place. To raise the armour, it is necessary to place it in a stone cave or a shady place, and keep the surrounding environment moist. The armour is afraid of strong light. If it is exposed to the hot sun, the body of the armour is easy to dry and the meat is easy to rot. And its food habit is unique, it feeds on the moss algae on the stone, so it is suitable for the moss algae on the stone to feed it. If there is a lack of moss algae, the armour will not be full of food, and the body will gradually lose weight, and it will be difficult to survive in the end.
These two, the life and warmth of the fish in heavy water, and the dampness and the moss algae that the armour resides in and eats, are the key to its existence. If it is raised according to this condition, the armour can survive for a long time; if it is not,
