In recent years, there have been a large number of fishpond pools in the intertidal zone along the coast. Due to various reasons, the pools of many units have been abandoned, which has resulted in a huge waste of production materials and facilities. In the intertidal zone, raising the Baochi rockfill and raising the ginseng in the intertidal zone can change this passive situation. The main technologies in the operation are described below for reference. First, the choice of venue. The ginseng pool should be selected to have smooth flow, small wind waves, stable salinity, and no sea areas with polluted and wild seaweeds. Special attention should be paid to the fact that there should not be a large amount of fresh water injected during the rainy season. Second, the block law of stone. Accumulate stones in the pool in the direction of the tide to prevent storms from destroying them. The size of the block stone is preferably 10 to 20 kilograms. The barrier stone should be 0.8 to 1.0 m from the dam, and the width of each barrier stone should be 1.0 m, the height should be 1.2 to 1.3 m, and the spacing should be 0.5 to 0.6 m. The height of the concrete dam of the pool should be 2.0 m or more. Third, the release of sea cucumber seedlings. In order to shorten the breeding cycle in the production and quickly see the benefits, it is required that the seedlings to be put in the first-year-old seedlings are good, and the size is about 50 grams. Should choose the body surface without injury, strong vitality, the integrity of the thorn, the internal organs without discharge of the seedlings. At the beginning of May, 8,000 to 10,000 heads of seedlings were planted per acre, and by the middle of June of the second year, the weight of each head can reach more than 150 grams, and the survival rate of breeding was more than 80%. Fourth, the water quality control. The water level in the ponds should be 1.5 to 1.6 meters, and it should be at least 1.8 meters in the summer rainy season to prevent the fluctuation of pool water salinity and affect the normal growth of sea cucumber. In addition, the hot summer pool water level should be kept as high as possible, and Donna ground change, so that the temperature of the water pool to reduce as much as possible, the cold water in winter full of less water, maintain proper temperature, so that rapid growth of sea cucumber, individual increase Remarkable. Fifth, feed feeding. Stichopus japonicus mainly uses benthic diatoms in muddy sand and humus and organic debris of seaweed as bait. Therefore, it is recommended that more seaweed, seaweed, kelp, and other grinds and sea mud should be fed to the sea cucumbers (scraping at the bottom of the pool. Mud mixture. 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 the morning was 20%. Summer sleep and cold winter conditions determine whether or not to vote. Sixth, daily management attention issues (1) pay attention to listening to the weather forecast to prevent the injection of large quantities of fresh water. (2) There must be special care for day or night to prevent theft. (3) Scientifically adjust the water level to prevent sea cucumbers from escaping into the sea and cause unnecessary losses. (4) Diligently observe the growth of sea cucumber and find that the problem is solved in time. (5) Regularly check the water quality so that appropriate measures can be taken. (6) Prevent oil pollution and related chemical substances from polluting and eroding ponds.
