Deep well booth holothurian culture method

Abstract

The invention provides a deep water well shed holothurians breeding method, and is characterized in that (1) fry stocking: the fry specification is 3-5cm, the stocking density in the prophase of the breeding is 40-60 heads per m2, and the fry is required to be sanitized before stocking; (2) breeding managing: a deep water well shed whose sea water temperature is 12-17 DEG C and whose salinity is not less than 25 per thousand is selected, slight flow raising method is adopted during the growth period, the daily flux is 1-3 times of the raising water, and air charging breeding is adopted when the water flows; sea mud, tail algae powder, and kelp power and auxiliary forage are fed 1-2 times every day, and the feeding amount is 1-5 percent of the weight of the holothurians. Taking full use ofthe establishment of the existing deep water well shed, breeding the holothurians effectively and healthily, the invention is easy to be operated and managed, and the invention can save energy and lower the consumption, can save water and reduce pollution, and can reduce the breeding period, as well as improve the breeding efficiency greatly.

Description

technical field [0001] The invention belongs to the aquaculture technology, and relates to a method for cultivating sea cucumbers, in particular to a method for cultivating sea cucumbers in deep-water well greenhouses. Background technique [0002] At present, with the improvement of people's living standards, the medicinal value of sea cucumbers has been continuously developed, and the price has been rising all the way. In 2007, the price of fresh ginseng rose from 200 yuan / kg to 250 yuan / kg, and the shortage of dry sea cucumbers in the world is nearly 10,000 yuan. Ton. In recent years, people have adopted different methods to cultivate sea cucumbers according to local conditions and have achieved success, mainly including shrimp pond culture, offshore raft cage culture, seabed sinking cage culture, intertidal zone cofferdam culture and industrial abalone polyculture, etc. Several methods. However, various restrictive factors such as high investment, low yield, long breed...

Problems solved by technology

However, various restrictive factors such as high investment, low output, long breeding cycle, low efficiency and high environmental requirements in the above farming methods have hindered the further development of sea cucumber farming and are far from meeting the growing market demand.
