How to raise sea cucumbers?

First, the seedling method: generally there are two methods of putting seedlings, which can be directly put in, so that the sea cucumber seedlings can also be attached to the stones or other objects in the breeding pond to grow, this method is suitable for the length of more than 3 cm of large size ginseng seedlings. There is also a net bag placement method, but you need to add small stones, in order to prevent the net bag from flowing casually, the bag mouth should also be slightly pierced, so that the sea cucumber can climb out on its own, and the corresponding small ginseng seedlings are suitable for 1-2 cm.

Second, the problem of water quality: in fact, the important factor related to the growth of sea cucumber is the problem of water quality, before putting the sea cucumber into the water quality sampling, only the water quality that meets the conditions can be released. And we all know that the mortality rate of ginseng seedlings in the early stage of breeding is relatively high, and the analysis results are because the stocking conditions are relatively different from the original, and the death is caused by the lack of adaptation to the new environment.

Therefore, the water temperature of the stocking pond should be as consistent as possible with other microorganisms in it. Or farmers can buy the ginseng seedlings plastic bags floating on the water surface of the stocking pond, and then slowly add the water in the pond when the temperature is about the same, in order to create an adaptation process for the ginseng seedlings.

3. Seedling location: A good location can greatly increase the survival rate of sea cucumbers, and it is generally necessary to choose a deep water area, a relatively stable environment, a smooth water circulation and a place with sufficient feed, and more ginseng seedlings can be placed. It must not be placed on loose and loose silt, which can easily cause ginseng seedlings to fall into the silt and die.

Another point is to try to choose a non-ventilated place to avoid the impact and damage of strong winds on ginseng seedlings.

Fourth, timely water change: the purpose of water change is to regulate water quality, improve the living environment of ginseng seedlings, and the specific amount of water exchange should be determined according to the water quality, as long as the water quality is good, you can reduce the number of replacement, on the contrary, if the water quality is already very poor, it is necessary to change a large amount of water, but in fact, the frequency of water change will affect the growth of ginseng seedlings. For most sea cucumber farmers, the daily water change should be maintained at more than 10%.

1. Pond aquaculture: ponds can be established in mid-tide or low-tide areas. Pond farming needs to pay attention to the control of density, generally speaking, the number of put per mu is better to control about 4000, otherwise it may affect the growth of sea cucumbers.

Some artificial sea cucumber reefs can be placed in the pond. The water level of the pond needs to be paid attention to, and it can be controlled to a depth of about 2 meters. Sea cucumbers also need to be fed, either by feeding them on artificially cultivated algae or aquatic plants.

2. Bottom sowing culture: This breeding method refers to the way of breeding sea cucumber seedlings by transforming the environment at the bottom of the ocean. The diet of sea cucumbers is also mainly algae plants and plankton.

Because the environment is not easy to control during bottom seeding, the survival rate will be relatively low, but the nutritional value of this sea cucumber is higher.

1. Construction of ginseng ponds: take advantage of geographical advantages in the middle tide zone or low tide zone, preferably the bottom of the reef, use concrete and stones to enclose the shape of the city, ponds of different sizes, and the windy sea area wall should be thickened and reinforced;

2. Release artificial sea cucumber reef: The purpose of building artificial sea cucumber reef is to provide a hidden place for sea cucumbers, and to reproduce a large number of seaweed and aquatic plants for sea cucumbers to inhabit, feed and hibernat;

3. Transportation of ginseng seedlings: usually wet and dry methods are used to transport ginseng seedlings;

4. Ginseng seedlings: the density of ginseng seedlings is not only related to water temperature and water quality, but also related to feeding management.
