Cage culture of sea cucumber is not only convenient to manage, but also more labor-saving in feeding management and fishing, and it is a good method to cultivate sea cucumber.
What are the advantages of sea cucumber cage culture?
1. Cage culture of sea cucumber is a new technology to protect seedlings by using the water above the cage. This technology consumes less cost, labor and problems, and the survival rate of seedlings in cages is high.
2. Long service life of the cage. The period of sea cucumber culture in cages is about 7 months, and the service life of cages is about 5~ 10 years.
3. Cage culture can be centralized, which avoids the waste of culture and has high resource utilization rate.
4. Reasonable cage layout can be more conducive to the growth of sea cucumber.
What are the methods of sea cucumber culture?
1, cage culture
Hanging cages or cages are put into the sea, and sea cucumbers are put into cultivation. Food depends on algae growing on the internet, algae is insufficient, or artificial feeding is needed to accelerate the growth of sea cucumbers. This farming method requires a certain depth of water and natural water circulation. The disadvantage is that it is not resistant to wind and waves and has high requirements for the environment.
2. Bottom sowing sea cucumber
That is, the sea cucumber seedlings are sown in the water depth of 0-20 meters in the natural sea area to let them grow naturally, and the breeding period should be more than 4 years.
In this way, the wild sea cucumbers planted at the bottom that participate in natural reproduction are mixed together, because they cannot be distinguished, and the number of sea cucumbers planted at the bottom is far greater than that of wild sea cucumbers, so they can only be counted as sea cucumbers planted at the bottom.
Bottom-sown sea cucumber is infinitely close to wild sea cucumber, and its quality and nutritional price are very high. However, due to the limitation of sea area, long culture cycle, low yield, difficult storage, easy theft and high fishing cost, the yield of bottom-sown sea cucumber is limited, accounting for less than 10% of the national sea cucumber output, and only some big brands have their own culture sea areas.
3. Shallow sea capture
Is to build dams in coastal areas and concentrate on captivity. The breeding cycle is about 2 years, the yield is objective and easy to look after and catch. At present, the coastal waters are basically occupied by this ginseng pond.
4, shrimp pond culture
It is also a kind of captive culture, which uses the early abandoned shrimp pond to cultivate sea cucumbers, so it is called shrimp pond culture. It is to dig a pond in the open space near the sea, waterproof the bottom of the pond, and imitate the underwater environment to throw stones and rubble into the pond as artificial reefs for breeding.
5. Greenhouse agriculture
Is to build a breeding pond indoors for breeding. Because the temperature and water temperature can be controlled, the breeding cycle is short, and it can be produced about 1 year.
