1. There are many details to consider when breeding sea cucumbers. What are the techniques for breeding sea cucumbers?

If we talk about the growth cycle of sea cucumbers, they can be divided into two types. First, let's talk about wild sea cucumbers. Wild sea cucumbers are of the best quality among all types of sea cucumbers, because sea cucumbers are completely in a wild state. Their nutritional value is very high, but their growth cycle is longer. Generally, ponds are built by sea.

Because it can make good use of geographical advantages, using rocks, cement and stones to form and urban effects, and use the fluctuation of pool water to make a new replacement every day. Generally, it is necessary to ensure that the water replacement is about 30%, and the depth of the pool is about 1.5 meters. Artificial sea cucumber reefs are used to provide a good living place for sea cucumbers, but a large number of algae and aquatic plants need to be cultivated in this artificial sea cucumber reef. The source of materials can be covered to make tiles, bricks, scallop cages, etc. The wall panels are as close to the original state as possible, so as to best ensure the wild reproduction of sea cucumbers. Disinfection of water before entering the ice can effectively prevent sea cucumbers from husking.

Generally speaking, if 300 to 500 sea cucumber seedlings are placed in an area of ​​10 to 30 square meters, the survival rate can reach 35%. However, the relationship between the placement density of sea cucumbers and the water temperature and water quality must be coordinated well to achieve the best survival rate of sea cucumbers. The temperature requirement for the growth of sea cucumbers is to keep the aquaculture water temperature within the appropriate growth range, thereby accelerating the growth rate and shortening the aquaculture cycle. Raft aquaculture refers to the artificial aquaculture of sea cucumbers in fish-shaped cages at sea. The best sea area for raft aquaculture is to choose a good harbor surrounded by mountains on three sides, with slow return wind and a water depth of 5-9 meters.

You also need to keep enough oxygen in the water, regularly remove some weeds in the water, protect the environment, and do not pollute the water source.

When breeding sea cucumbers, you must choose a relatively spacious site, keep it clean and sanitary, maintain a certain temperature, and the number of fish must be maintained at a certain level. The water quality must be changed frequently.

2. What is the cost per acre of sea cucumber farming?

Qingdao: Sea cucumbers are divided into wild and farmed. Generally, wild ones are more expensive than farmed ones. The price varies according to the length and distribution of the spines. Generally, farmed ones are cheaper if you buy them directly in the coastal farm areas of Laoshan. The price of dried ones is

The wild ones are priced between 1200 and 1800 yuan, and are generally 300 to 400 yuan more expensive.
