Summary of the invention
In order to overcome the problem that existing holothurian culture method exists, the invention provides a kind of holothurian culture method that improves output, shortening culture-cycle, improves sea cucumber quality and yield rate.
The present invention is achieved through the following technical solutions: a kind of holothurian culture method is characterized in that method is as follows:
(1) selects the nesting kind: in culturing the pond, select shrimp and sea cucumber cover to support;
(2) culture the pond management: after adopting bleaching powder full pond sterilization, in culturing the pond, throw in not specification stone heap and/or net cage; 1.0~3.0 meters of the depth of waters, 12 ℃~18 ℃ of water temperatures, salinity 25 ‰~35 ‰, every day, quantity of exchanged water was no less than 10%, and the dissolved oxygen in the breeding water body is greater than 5 milligrams/L;
(3) cistern is set: the cistern area is not less than cultures 20% of pool area;
(4) water inlet is filtered, the fresh water discharging: at breed pond water inlet 80 orders sleeve net is set; Culturing the pre-buried fresh water floss hole in nearly water surface place, pond;
(5) transportation of seedling: adopt wet method or dry method, described wet method is: seedling is placed in canvas bucket or other containers, adds seawater, the inflator pump inflation; Or seedling is placed in the plastic sack, add seawater, after filling oxygen sack is tightened, transport; Described dry method is: seedling is put in plastics or other chests, and lay sea-tangle grass, absorbent cotton at the bottom of the case, seedling evenly keeps flat, the gauze that loam cake drenches with seawater;
(6) seedling is put in a suitable place to breed: seedling is thrown in 9~November of every year, adopts direct input method or mesh bag to throw in method; Described direct input method is: seedling is directly rendered to artificial Hai Jiao get on; Described mesh bag input method is: seedling is contained in the 20 purpose mesh bags, and 100~200 every bag, put finger stone in the mesh bag into, with fly-off safeguard and mobile, be placed on the artificial Hai Jiao, the mesh bag mouth opens wide, and allows seedling slowly climb out of from mesh bag;
(7) breed in the middle of the seed: the young ginseng that will breed is then bred the pond through the centre, utilizes scallop cage or net cage, through about one month intermediate rearing, rejects sick and weak seedling;
(8) additional throwing something and feeding: replenish the bait of throwing something and feeding and being made up of benthic diatom, mouse tail algae, thick starch and/or fish meal, daily ration of feeding is 5~10% of a sea cucumber body weight, and day bait throwing in once.
The invention has the beneficial effects as follows: 1. the present invention is by being provided with cistern, and water flows into after the cistern precipitation purifies and cultures the pond, can in time take measures in case find quality problem.2. by 80 orders sleeve net being set water inlet is filtered, prevent that fish-egg, trash fish etc. from entering at breed pond water inlet.3. breed by in the middle of the seed, through about one month intermediate rearing, reject sick and weak seedling, making and culturing pond confidential reference items shoot survival percent is 85%~100%.4. by the fresh water delivery pipe being set, strengthen culturing water management, be convenient to rainfall discharging fresh water when big at nearly water surface place.5. sea cucumber depends merely on that natural bait growth is slow, the cycle is long, some bait of forming by benthic diatom, mouse tail algae, thick starch and/or fish meal etc. of therefore throwing something and feeding in right amount, the principle of throwing something and feeding be rather lack not many.6. culture the pond and carry out the sterilization of the full pond of bleaching powder, include clear water then in and water quality is cultivated, utilize biologic products such as photosynthetic bacteria, strengthen water quality and cultivate, promote the growth of shrimp ginseng.7. adopt sea cucumber and shrimp to raise together with, sea cucumber can purify water, and can utilize shrimp material and excreta etc., thereby reaches sea cucumber, shrimp bumper harvests.
The present invention by be provided with cistern, with prawn raise together with, intake filtration, rich water, replenish and breed, throw in beneficial microbe in the middle of throwing something and feeding, being provided with and keep methods such as good water quality, solved the problem that holothruian cultures exist.In the practice, culture garden autumn in 2008, culture 100 mu of sea cucumbers, throw in 700,000 of seedlings Yingkou Er Dao ginseng shellfish, 24.5 ten thousand of recaptures, the rate of recapture 35%, average body weighs 88 grams.Than former breeding way, the rate of recapture increases by 7%, 43 kilograms of mu volume increase.
Embodiment
A kind of holothurian culture method of embodiment, method is as follows:
(1) selects the nesting kind: in culturing the pond, select shrimp and sea cucumber cover to support;
(2) culture the pond management: after adopting bleaching powder full pond sterilization, in culturing the pond, throw in not specification stone heap and/or net cage; 1.0~3.0 meters of the depth of waters, 12 ℃~18 ℃ of water temperatures, salinity 25 ‰~35 ‰, every day, quantity of exchanged water was no less than 10%, and the dissolved oxygen in the breeding water body is greater than 5 milligrams/L.Situation according to culturing water adds photosynthetic bacteria, the quantity of harmful substance and other organic pollutants in the minimizing breeding water body.
(3) cistern is set: the cistern area is not less than cultures 20% of pool area;
(4) water inlet is filtered, the fresh water discharging: at breed pond water inlet 80 orders sleeve net is set; Culturing the pre-buried fresh water floss hole in nearly water surface place, pond;
(5) transportation of seedling: adopt wet method or dry method, described wet method is: seedling is placed in canvas bucket or other containers, adds seawater, the inflator pump inflation; Or seedling is placed in the plastic sack, add seawater, after filling oxygen sack is tightened, transport; Described dry method is: seedling is put in plastics or other chests, and lay sea-tangle grass, absorbent cotton at the bottom of the case, seedling evenly keeps flat, the gauze that loam cake drenches with seawater;
(6) seedling is put in a suitable place to breed: seedling is thrown in 9~November of every year, adopts direct input method or mesh bag to throw in method; Described direct input method is: seedling is directly rendered to artificial Hai Jiao by certain density get on; Described mesh bag input method is: seedling is contained in the 20 purpose mesh bags, and 100~200 every bag, put finger stone in the mesh bag into, with fly-off safeguard and mobile, be placed on the artificial Hai Jiao, the mesh bag mouth opens wide, and allows seedling slowly climb out of from mesh bag;
(7) breed in the middle of the seed: the young ginseng that will breed is then bred the pond through the centre, utilizes scallop cage or net cage, through about one month intermediate rearing, rejects sick and weak seedling;
(8) additional throwing something and feeding: replenish the bait of throwing something and feeding and being made up of benthic diatom, mouse tail algae, thick starch and/or fish meal, daily ration of feeding is 5~10% of a sea cucumber body weight, and day bait throwing in once.
Adopt said method, culture the garden Yingkou Er Dao ginseng shellfish and carried out the breed of sea cucumber autumn in 2008, culture 100 mu of sea cucumbers, throw in 700,000 of seedlings, 24.5 ten thousand of recaptures, the rate of recapture 35%, average body weighs 88 grams.Than former breeding way, the rate of recapture increases by 7%, 43 kilograms of mu volume increase.
Above embodiment does not limit the present invention just in order to describe the present invention in detail, and technical scheme of the present invention is applicable to any holothruian cultures field.
