Discussion on the mode and key points of sea cucumber breeding

Sea cucumber is a echinoderm, which ranks first among seafood treasures and has rich nutrition. In recent years, people have adapted to local conditions and adopted different breeding methods for the success of sea cucumber cultivation. Now we will briefly introduce its methods and points.
First, shrimp pond breeding points
1. Using existing shrimp ponds, artificial reefs such as stones, tiles, and old tires are placed for sea cucumbers to inhabit.
2. Juvenile feeding density is about 5cm in body length (weight 50g/head) 3000 seed heads per mu -5000 heads.
3. The baits are mainly benthic diatoms and organic detritus attached to the deposited reefs. At the same time, they are fed with algae such as rattus, kelp, and nepota, and they can also be fed with artificial diets.
4. The depth of the shrimp pond should be maintained at 1.5-2m, and the summer and winter water levels should be at a high level so as to facilitate the smooth hibernation and wintering of the sea cucumber.
5. It is forbidden to apply chemical disinfectant, oil, etc. to the shrimp pond to prevent the autolysis of the sample. In addition, pay attention to the temperature and salinity of the pool water, pay close attention to the water environment surrounding the shrimp pond when receiving water, and ensure that the exchange of pool water is 10-15% per day.
Second, the main point of sea bream farming
1. The sea area has a smooth flow, no major storms, and no pollution from industrial and domestic sewage.
2. Scallop cages and abalone cages are commonly used for breeding. Plastic buckets, and most of them mixed with abalone, have a length of about 5cm, a density of 200-300 heads per square meter, a suspended water layer of 5-8m, and a cage spacing of 3m-4m.
3. The bait is rat-swiss, kelp or artificially-combined bait. As the individual grows, the density is gradually reduced and the degree of damage of the cage is checked at any time.
4. Before a typhoon or storm surge arrives, the cage should be lowered in time to avoid loss.
5. Sea cucumbers and sea cucumbers can also be mixed with algae.
Third, the submarine cage culture points
1. Select inner bay area with calm sea and smooth flow, without large amount of freshwater injection, and use nets made of coarse steel bars for roundness; for rectangles, outer nets, and put stones (3kg/-5kg/piece) /
2. Stocking density is 3-5cm body length 200-300 head / square meter, bait is artificially mixed with food or kelp. Rattus, etc., can be fed once every 3 days - 5 days depending on the situation.
3 Pay attention to the damage of net clothes daily and evacuate in time according to the speed of growth of sea cucumbers.
Fourth, the inter-tidal belt stone ginseng points
1. In the intertidal zone, according to the characteristics of the terrain, steel bars, stones and cement are used to build dams.
2. The height of the dam should be determined according to the highest tide level in the calendar year. There are holes for drainage and drainage at the bottom of the dam, which can naturally absorb water and drain water.
3. The stocking density was 20,000 cm long per head per 1-2 cm of seedlings, and 8000 heads/mu of 8000 heads/mu were about 5 cm.
4. The bait may be artificially mixed with bait, and may also be kelp, benthic diatoms, and rata.
5. Pay attention to the injection of fresh water during the rainy season and the high water level should be advanced. Chemical disinfection substances are strictly prohibited. Oil pollution, to prevent the autolysis of the body. Regularly remove starfish and other predators.
Fifth, indoor factory baguette polyculture points
1. The use of existing facilities at the factory-financed Bao workshop has resulted in the use of mixed sea cucumbers.
2. Polyculture density is 4cm abalone 100/m2, while sea cucumber is 3cm-4cm6 head/m2 -8 heads/m2.
3. During the cultivation period, deep seawater wells are used for cooling in the summer, warming water is available in the winter, and the sea cucumbers are not asleep, shortening the growth cycle.
4. Abalone mixed sea cucumber can increase the survival rate of abalone, reduce the loss of bait, and reduce production costs.

Fresh air through increasing oxygen were abandoned special fan, airway pressure uniform expansion and achieve aerator, large fine bubbles design value (diameter from 20 ~ 30UM), and in the water pipe smoke drift, rise in the extremely slow, dissolved oxygen has obvious effect, thus greatly improve the oxygen in water, electricity, improve liquidity increases the breeding density.
