How does sea cucumber breed disease less? These four major technical points are worthy of reference!

As the health care value and health preservation value of sea cucumbers are more and more favored by people, the sea cucumber culture market is also developing rapidly, but many people find that sea cucumbers are not easy to grow and get sick easily after experimenting with sea cucumbers, so how to cultivate sea cucumbers with less disease? What are the technical points?

I. the location of cultured sea cucumbers must be reasonably selected.

When choosing sea cucumber culture ponds, farmers should avoid the dense areas of sea cucumbers and try to choose the culture areas which are close to the sea area, rich in natural bait, smooth tidal current, no fresh water injection, good water quality, sufficient number of benthic diatoms, good sediment sediment and suitable water depth.

According to the specific conditions of ginseng ponds, reasonable selection of reef types, according to stacking standards, reasonable placement of reefs, to provide favorable conditions for sea cucumber habitat and summer, to ensure the normal growth of sea cucumbers. Specifically, the bottom of the pool is required to be flat and free of sundries, preferably a sediment bottom, slope protection on both sides of the dam is required, and there is no leakage, and the inlet and drainage area in front of the valve is laid with bluestone or other hard materials, so as to ensure that the long-term impact of water intake and drainage will not cause damage and depression in the area.

2. Ginseng ponds where sea cucumbers are cultured must be disinfected regularly

Sea cucumber is a kind of benthic aquatic animal, sea cucumber perennially inhabit the bottom of the water layer, sea cucumber feces, algae and silt will accumulate on the bottom and reef, and after winter and summer, the low-temperature algae at the bottom of the pond begin to rot and deteriorate, breeding bacteria, molds and other bacteria, which affect the normal growth of sea cucumbers, resulting in weak lean bodies and poor resistance.

Therefore, the farmers should do a good job of desilting and disinfection in time to ensure the water quality and sediment environment of the ginseng pond and create a good ecological environment to reduce the occurrence of sea cucumber diseases.

III. Matters needing attention in the selection of sea cucumber seedlings

1. Selection of sea cucumber seedlings.

When selecting ginseng seedlings, it is necessary to ensure that there is no damage to the body surface, sufficient vitality, no mucus, strong tube foot adhesion and bright color, strong spurs, natural extension, and strong ability to avoid light.

In addition, it is also necessary to ensure that the quality of ginseng seedlings must be quarantined and qualified by the relevant quarantine departments before the cultivation of sea cucumbers can be officially started.

2. Release density of sea cucumber seedlings.

In addition, the stocking density of sea cucumbers affects the yield and quality of sea cucumbers. Therefore, farmers should reasonably control the stocking density according to the productivity and water quality of ginseng ponds, so as to strengthen the system of sea cucumbers, improve the growth rate of sea cucumbers and reduce the incidence of diseases. You can roughly refer to if the size of sea cucumber is 200001000 kg-1, the density is controlled at 600000120000 hm-2.

3. The method of releasing sea cucumber seedlings.

(1) net bag delivery method

That is, first put the sea cucumber seedlings into the net bag, in order to prevent the net bag from floating at will with the pool water, you can put a moderate weight stone in the net bag, and put the ginseng seedlings into the designated position, and let the ginseng seedlings climb out freely.

(2) Direct delivery method

The method is relatively simple, and the sea cucumbers can be directly scattered on the reefs.

Fourth, the prevention of sea cucumber diseases should be timely.

At present, bacterial diseases are the most common diseases in the process of sea cucumber culture, especially during the period of "summer hibernation" and "hibernation" of sea cucumbers.

The main results are as follows: 1. During the release of ginseng seedlings, farmers should try their best to put in the seedlings with strong physique and large size, and disinfect them with medicine solution before entering the pond, so as to reduce the occurrence of sea cucumber diseases.

2. For disease-free adult ginseng, farmers can regularly use quicklime for disinfection in order to improve the resistance of adult ginseng.

3. For the ginseng pond which has already occurred, the farmers should actively improve the water quality, increase the water exchange volume, and take appropriate treatment measures according to the specific conditions of the disease.

4. The water used for raising sea cucumbers should be disinfected by ultraviolet rays, and the culture density of sea cucumbers should be controlled, and the organic impurities and most microorganisms in the pond water should be effectively removed, and the attachment base should be cleaned in time. To ensure that the overall living environment of sea cucumbers has been in a clean state, effectively reduce the growth of bacteria.

5. In the aspect of feeding sea cucumber feed, it is necessary to ensure that sea cucumber feed is clean and fresh, and it is strictly forbidden to feed sea mud directly.
