Only when sea cucumbers are raised in this way can they be high-yielding and earn a lot of money every year.

We all know the value of sea cucumbers. The market value is extremely high. Many people make money by raising sea cucumbers. So do you know how sea cucumbers can produce high yields? Let's take a look at it.

I. Culture management

The main results are as follows: 1. From the release of the seedlings to the end of May, the water level in the ginseng pond is kept between 1.0m and 1.2m, which is conducive to the rise of water temperature in spring. Fermented chicken manure is used to fertilize the water and keep the water transparency at 30~40cm. In order to avoid the loss of organic matter, the daily water exchange is controlled at about 10cm.

From July to August, with the increase of air temperature and water temperature. Gradually deepen the water level. Keep the water depth above 1.8m and do not change water greatly in summer, which is beneficial to maintain the stability of water tribute and water temperature, help sea cucumbers to sleep in summer and pass through the high temperature period smoothly.

3. After September, when the water temperature drops to 23C, the hibernating sea cucumbers come out to look for food one after another. At the same time, autumn is also the peak season for the growth and weight gain of sea cucumbers. The amount of water should be changed at 20 "30cm every day, because increasing the amount of water exchange can bring more natural bait in the sea, which can ensure the rapid growth of sea cucumbers.

4. After our region enters November. With the continuous invasion of the cold current, the air temperature and water temperature are decreasing. When the water temperature is 7: 8C, most of the large sea cucumbers begin to hibernate in the reef, and the amount of water exchange should be about 1015cm, mainly to replenish water and raise the water level.

5. Before the ice is sealed, the overwintering water depth should be kept above 2.0m, and some seawater can be properly replenished during the spring tide in winter, but the water intake should be slow, not exceeding 20cm, so as to avoid excessive changes in water temperature and stress reaction to overwintering sea cucumbers. After heavy snow, sweep the snow on the ice surface immediately and increase the light intensity of the sea water under the ice, which is beneficial to photosynthesis. Increase the content of dissolved oxygen in the pool water under the ice to ensure that sea cucumbers survive the winter smoothly.

Clear the pond once in two or three years to create a good growth environment for sea cucumbers.

1. Through several years of sea cucumber culture, we found that the newly built sea cucumber pond has the advantages of fast growth, high survival rate, less disease and high yield. we decided to change the mode of perennial water in the sea cucumber pond, not cleaning the pool for many years, and the mixed culture and harvest of different specifications of sea cucumbers. This model can not clear the pool in time, resulting in serious aging, blackening, odor, hydrogen sulfide and ammonia nitrogen seriously exceeding the standard. Some farmers rely on the use of sediment modifiers and biological agents to improve and alleviate the substrate aging, which can not fundamentally solve the problem of pool bottom aging, and can not guarantee the high yield of sea cucumbers.

2. The large size ginseng seedlings were cultured for 1.5 ~ 2 years. In the case of reasonable seedling density, 80% can meet the commercial specifications, and the seedlings will be replenished once in the spring of the third year. In the autumn of the fourth year, it is obvious that there will be a fixed cost of clearing the pool in three years. However, the I attachment bases we put in are conducive to cleaning the pool, which can effectively reduce the cost of cleaning the pool, and can also ensure the high yield of sea cucumbers. After deducting the cost of asking for the pool, it will also bring ideal economic benefits for sea cucumber farmers. Through several years of experiments on high-yield culture of sea cucumbers, we have summed up some experiences to share with sea cucumber farmers: if we want to make sea cucumbers high-yield, we must raise water well and raise the bottom of the pond well because sea cucumbers are benthos, and good bottom quality is the guarantee of high-yield sea cucumber culture.

All right, the above is the high-yield technical content of sea cucumbers brought by the editor of Tuliu.com. I hope you like it. I'll see you next time.
