Raising sea cucumber dedicated products which regulate water quality

Raising sea cucumber dedicated to regulate water quality products which oplopanax Echinodermata, Holothuroidea, mainly in Shandong, Liaoning, Hebei and other places. In recent years, sea cucumber prices, attracted the attention of many investors, the Senate pool development and construction in full swing. But in recent years, raising sea cucumber from, the quality of the faded, disease in increase, plus sea cucumber aquaculture technology is backward, raising the risk of sea cucumber growing. To reduce the risk, provisions were introduced Senate better sea cucumber farming techniques. How ecological habits of sea cucumbers? Natural sea, sea cucumber farming inhabits shallow depth of 3-20 meters, water quality of life in the clear, rich food, no fresh water inflow, algae lush reef bottom or bottom sediment, salinity 28 ‰ ~ 32 ‰, PH7.8 ~ 8.4, the water temperature no higher than 30 ℃, the area does not freeze in winter. Sea cucumber farming food with unicellular algae, benthic diatoms, organic debris, mixed with organic matter in the sediment and small animal carcasses for food, the use of silt tentacles even when prey be swallowed. Sea cucumber is a boreal species, water temperature survival -1.5 ~ 30 ℃, the water temperature below 3 ℃ while reducing food intake in a semi-dormant state; when the water temperature is 10 ~ 15 ℃ maximum food intake; intake of food intake when 17 ~ 19 ℃ but also greatly decreased; when entering estivation exceed 20 ℃. So, to say, temperature range of farmed sea cucumber 3 ~ 20 ℃, the water temperature below 2 ℃ or higher than 23 ℃ when you stop growing. Affected by water temperature, sea cucumber farming has two growing seasons in one year, one in spring in mid-March --5 month, and the other is the fall in September --11 months. Sea cucumber farming has two fast growing, about one water temperature to 10 ℃ before aestivation, body length increased significantly at this argument, and the body wall is thin, metal body long growth period; Second, after the temperature dropped to about 10 ℃ aestivating When this amount of weight gain, body wall thickening. Thus, more than two periods of feeding, changing the water more, especially in the fall to increase the protein content of the diet to promote rapid growth of sea cucumber. Sea cucumber farming agricultural Beverly bacteria em nationwide telephone orders 15517336226 QQ 1103816009 how to transform farming ponds of sea cucumber? Sea cucumber aquaculture ponds 20 to 40 acres, rectangular north-south direction, depth of 2 to 3 meters is appropriate. Excavation in the pool a 30 ~ 50cm deep ring groove, the ring groove area accounted pool area of ??1/4 to 1/5 or so, not too much slope. Better sediment ponds can transform the following ways: First, stoning law, every about 1-1.5m stoning pile, 0.5 ~ 1m3 around each pile, also be free to throw rocks to the pool, tiles and the like; The second is the construction of artificial reefs parameters, using porous cement manufacturing, multi-level, pore size of about 8 ~ 10cm, easy prey sea cucumber habitat. Shrimp in the form of soft mud bottom hanging objects, that is piling shrimp ponds, with a rope and old mesh set up a level, put tile, baskets cage, slate and other tires on top. Row and row spacing of 30 ~ 50cm, height of about 30cm, into the drainage along the direction of arrangement. How Qingchi and fertilizer? Pond water with submerged reef parameters for the degree, mu quicklime or bleaching powder 10kg 80-100kg immersion disinfection, two days back dry water, water with a 60 mesh screen filter 50 ~ 60cm, acres 施伟嘉 fertilizer treasure 0.5-1kg, agricultural Beverly EM bacteria 200 to 300 grams, until 7-10 Tianchi water was dark brown, beneficial bacteria and beneficial em algal blooms can be put into seedlings. What quality of sea cucumber seedlings are the criteria? Body stretch thick, bright color, flesh thorns and high; head and tail move freely, fast motion, stretching natural, non-stick and loose bowel movements, eat fast. Body color dark and slimy burns bald and short, stool sticky tube feet determined not powerless. Ginseng seedlings how to determine the stocking density? Ginseng seedlings stocking density should be controlled according to the specifications and reasonable size, usually 300 to 500 / kg in 5000 to 10,000 acres of discharge; specifications from 30 to 50 / kg from 2000 to 3000 acres release. Seedling density to wait any time to adjust based on water quality, water changes the size of the extent of water bodies and whether too fat feeding.

Fingerlings before stocking the best selection of agricultural Beverly bacteria aquatic em, kill all germs. Fangmiao put on a wetsuit, sea cucumber seedlings participate in the bucket, evenly sprinkle on the stones, tiles, starting hand out of the water about 10cm, doing so can improve the survival rate of seedlings ginseng, but also to maintain the bottom silicon algae reproduce effectively. Second, the use of mesh bag delivery method: 1cm about juveniles attachment and activity is weak, such as direct delivery in the pool will inevitably lead to a large number of deaths, ginseng seedlings can be installed in the 20 mesh bags, each bag of 100 ~ 200, mesh bags into small stones, to prevent the float and move on the artificial reef Senate. Net bag open, allowing the reference vaccine crawled out from the net bag.
