Inter-tidal Baochi breeding sea cucumbers serve two birds with one stone

In recent years, as the benefit of raising the abalone was relatively high, there were a lot of abalone-bearing abalone in the intertidal zone in the coastal regions. However, because of the subsequent decline in the benefit of raising the abalone and other reasons, the utilization rate and efficiency of raising the abalone were low. Pools in many places are almost abandoned, leading to great waste of production materials and facilities. The cultivation of sea cucumbers in the intertidal zone with Baochi rock piles can effectively change this passive situation and realize the support of raising the abundance of the abalone.

1. The site selection for the ginseng pool should be based on the currents with smooth tides, small waves, and stable salinity, and there are no contaminated seaweeds with much wild seaweed. Pay special attention to the fact that there should not be a large amount of fresh water injected during the rainy season.

2. Stone block law in the pool to be stacked in the direction of the trend of stone, in order to prevent storms to destroy it. The size of the block stone is preferably 10 to 20 kilograms. The barriers should be at a distance of 0.8 to 1 m from the dam, and the width of each row should be 1 m. The height should be 1.2 to 1.3 m. The booth spacing should be 0.5 to 0.6 m. The concrete dam height should be more than 2 m.

3. Seedlings are planted in order to shorten the breeding cycle in production, and the sea cucumber seedlings to be planted should be 1 inseminated seedlings, and the size should be about 50 grams. Saplings should be selected that have no injuries on the body surface, strong vigor, complete semen, and no viscera discharge. . At the beginning of June, 8,000 to 10,000 heads of seedlings were planted per acre. By the end of June of the second year, the weight of each head can reach 150 grams, and the survival rate of breeding is more than 80%.

4. The water level of the water control control pond should be 1.5 to 1.6 meters, and at least 1.8 meters during the summer rainy season to prevent the fluctuation of the pool water salinity and affect the normal growth of the sea cucumber. In addition, the water level in the hot summer pool should be kept as high as possible. And Donna changes the temperature so that the water temperature in the pond can be reduced as much as possible. In the cold winter, water is exchanged for less water, and proper temperature is maintained. The sea cucumber grows quickly and the individual gains weight significantly.

5. Feeding of sea cucumbers to feeds is mainly based on benthic diatoms and seaweed humus and organic detritus in mud sands. It is therefore necessary to feed more feeds such as seaweed, scallopweed, and kelp, etc. (scrape) on production. Mixture of bottom mud). The captured fish, shrimps, crabs and snails can also be mixed with sweet potato powder, corn flour and sea mud. The fed amount was about 10% of the body weight and was fed twice a day. In the evening, the amount was 80%, and in the morning it was 20%. In summer and cold winter, it was determined that they would not cast or cast less.

6. Daily management Pay attention to listening to weather forecasts to prevent the injection of large amounts of fresh water: There must be special care for both day and night to prevent theft, scientifically adjust the water level, prevent sea cucumbers from escaping into the sea and cause unnecessary losses, and diligently observe the growth of sea cucumbers. Situation, found problems solved in a timely manner, often check the water quality conditions, in order to take appropriate measures; prevent oil pollution and related chemical substances, pollution, erosion and ginseng pool.
