Shrimp pond culture Using the existing shrimp ponds, put tiles, stones, old tires, etc. for artificial reefs for sea cucumbers to live. The density of young cucumbers is about 5 centimeters in length, with 3,000 to 5,000 seedlings per mu. Sea cucumbers take the benthic diatoms and organic debris attached to the reef as bait. At the same time, you can feed artificial bait, or feed sage, wakame, kelp and other algae. The water depth of the shrimp pond should be maintained at 1.5 meters to 2.0 meters, and the water level in summer and winter should be brought to a high level, so that the sea cucumbers can hibernate and overwinter smoothly. It is strictly prohibited to apply chemical disinfecting drugs and discharge oil into the shrimp pond to prevent autolysis of the cucumber. Also pay attention to the temperature and salinity of the pool water, pay close attention to the water environment around the pool to ensure that the daily exchange of pool water is 10% to 15%. Raft culture in the sea The sea area is smooth, no big wind and wave invasion, no industrial and domestic sewage pollution. Generally, abalone cages, scallop cages and plastic buckets are used for aquaculture, and most of them are mixed with abalone. The length of ginseng fry is about 5cm, the density is 200~300 heads/square meter, the hanging water level is between 5m-8m, and the spacing between cages is 3m-4m. The bait is rat tail algae, kelp or artificial bait. The density should be thinned out as the individual senator grows, and the degree of breakage of the net cage should be checked at any time. Before the typhoon or storm surge, the cage net should be sunk in time to avoid losses. Sea rafting sea cucumbers can also be mixed with algae. Undersea cage culture Choose the inner bay sea area with smooth tide, calm wind and waves, and no large amount of fresh water injection, and use coarse steel bars to make net cages, which can be round or rectangular, with the outer net cover, and put a number of stones inside (3kg~5kg/each). The stocking density is 200 to 300 ginsengs of 3cm to 5cm per square meter, and the bait is artificial bait or kelp, sargassum, etc. According to the situation, it can be fed once every 3 to 5 days, or once a week. Pay attention to the breakage of the netting in daily life, and thin it in time according to the growth of the sea cucumber. Disease control

Sea cucumber comparable to ginseng has a relatively high nutritional value as well as medicinal value, and has a relatively high economic benefits so in the sea cucumber has become the choice of many entrepreneurs doorway, sea cucumber in the process of cultivation of vortex worm disease occurs, what are the symptoms and diagnosis of the method?

[Pathogen] There are 16 genera and 33 species of gastropods, including 6 species of endoparasitic snails, 5 species of giant burrowing snails, 4 species of porcelain snails, and the rest of the 13 genera, each with 1 to 3 species.

[Symptoms] Gastropods parasitize the body surface, body cavity, digestive tract, respiratory tree and other tissues and organs of the spiny cucumber. The deep-sea bean monster snail (Pisolamia brychius) parasitizes on Oneirophanata mutabilis. The deep-sea bean monster snail adsorbs on the body surface of Oneirophanata mutabilis with its kisses and pierces into the body wall of the spiny cucumber with its kisses, passes through the body wall to reach the body cavity, and ingests nutrients with its kisses protruding from the parasitic tissues, the body cavity, and the blood, and a mass appears in the area where the kisses penetrate into the body wall.

[Diagnosis] Diagnosis can be made by taking the tissue of the diseased ginseng and examining it microscopically to find the pathogen.
