Technology of raising sea cucumbers in cages

If the bay is less affected by the external weather and the water depth is more than 5 meters without pollution, the cage size of 3m is the most suitable, and the sea water temperature should be about 18 ℃. Select the source of seed ginseng and put it reasonably. The mode of transport is mainly the use of short-distance transportation by cars, and the cages should be replaced according to different growth stages. Peel off the ginseng seedlings according to the change of water temperature, sell the well-grown sea cucumbers before hibernation, and take good care of the sea cucumbers that do not grow well.

Sea cucumber is a tonic with the function of health care, and the sea cucumbers originally used are all grown in the wild, that is, wild sea cucumbers. Because wild sea cucumbers grow in wild conditions, the living environment can not be guaranteed, resulting in a long number of years of growth, and the output can not meet people's needs, so people put forward the artificial culture of sea cucumbers. The most suitable way to culture in the sea area is to use sea cucumber cage culture, cage culture technology needs to divide the appropriate culture area in the offshore area and select suitable sea cucumber seedlings.

1. Choose the suitable sea area. Generally, bays with a water depth of more than 5 meters and less affected by wind, waves or tides should be selected, and the tidal current in the bay should be smooth, clean and pollution-free, and rich in bait.

2. How to choose the cage. Considering the convenience of operation, the cage should not be too deep. In general, it is more appropriate to choose a cage with a specification of about three meters.

3. Select the room of seed ginseng. The temperature of sea water determines the purchase time of ginseng, and it is more suitable for culture when the temperature of sea water is about 18 ℃. In some areas of northern China, the most suitable time for planting and breeding is from late May to the end of June.

4. How to select the category of species parameter. There are two kinds of species cucumbers, namely, artificially cultured sea cucumbers and natural sea cucumbers. Generally, artificially cultured sea cucumbers are selected in the early stage of culture and natural sea cucumbers are selected in the later stage.

5. The density of seed ginseng. The density of seed ginseng is 0.5 head per cubic meter, usually 3-6 heads of sea cucumber.

6. How to transport seed ginseng. The mode of transportation is to use the car for a short distance, with a journey time of 2 to 3 hours. A 100-liter plastic bucket is placed on the car and poured into the sea water. Each barrel is filled with 30-40 sea cucumbers, then covered with a barrel cover and shaded with a shading cloth.

7. The choice of cage replacement. The type of cage used at the beginning is 200 mesh. After the sea cucumber grows to the young cucumber, use the 60 mesh cage. When the sea cucumber grows to 3 mm, replace the 40 mesh cage. Finally, when the sea cucumber grows to 20 mm, replace the edible polyethylene net.

8. Why do you need to peel off the ginseng seedlings. The reason for the peeling of the larvae is that the sea water temperature in the aquaculture area is not constant and the sea water temperature often fluctuates.

9. The treatment of overwintering season. In the marine state, the environment of cage culture can not be artificially controlled, and the environmental temperature will change with seasonal changes. The Beginning of Winter, sea cucumbers will hibernate, at this time, it is necessary to sell the sea cucumbers that have already grown, and the sea cucumbers that have not grown well need to be taken care of.
