When Fig. 1-2 represented half tide, cylinder mould partly sank to the state in seabed.
During Fig. 1-3 expression full sea, cylinder mould breaks away from the state in seabed fully.
Fig. 2 is the left view of Fig. 1-3.
Fig. 3 is improved cylinder mould dividing plate, processes two big holes on original cylinder mould dividing plate.
Embodiment
Adjust raft body and the buoyancy rope and the lifting rope length of buoyant raft by above-mentioned Fig. 1, make it can be in the time of low water, the buoyancy rope adds the length of lifting rope greater than the distance of sea to the seabed, guarantee that cylinder mould can sink to the seabed fully, (as Fig. 1-1) when half tide or full sea, cylinder mould can partially or completely break away from seabed (as Fig. 1-2,1-3).
The concrete length of buoyancy rope and lifting rope is relevant with the quality in seabed, and buoyancy rope and lifting rope are short at the bottom of the silt, prevent that cylinder mould from being sticked by silt, otherwise husky mud spacer screen cage is difficult for can suitably being increased the length of buoyancy rope and lifting rope by sunken.Containing the needed a large number of nutrients of sea cucumber in the silt, is the main food source of sea cucumber growth, should guarantee to allow cylinder mould how stop in the seabed under the prerequisite that cylinder mould is not sticked by silt as much as possible.
Under the effect of trend, cylinder mould always is kept in motion in the seabed and twice change every day direction of motion, and this provides condition for the large-area food that obtains of sea cucumber, and this motion can prevent that also cylinder mould from being sticked by silt.Cylinder mould is not all to break away from the seabed every day, and only otherwise sticked by silt, the time that cylinder mould stops in the seabed can prolong a couple of days, and the news of adhering to living just break away from the seabed when rising by spring tide, allow trend rinse out sea cucumber too much on the cylinder mould and unwanted foreign material.Cylinder mould is not only done horizontal movement in the seabed, also can move up and down under the effect of wave, and when wave formed on the sea, buoyant spheres can raise by wave, and this motion also can make the cylinder mould part or all of seabed that breaks away from of moment sometimes.
Cylinder mould is stretching, again two bamboo poles are fixed together with cotton rope and cylinder mould, make cylinder mould keep propping up state.Can suitably on cylinder mould, increase the quantity of bamboo pole at the bottom of the lax especially mud or adopt thicker bamboo pole,, make it to be slightly larger than the proportion of seawater,, make it to be difficult for poaching to alleviate the pressure of cylinder mould integral body (comprising sea cucumber) to the seabed to adjust the whole proportion of cylinder mould.
Make a call to two circular holes for 1.5~2 times of (results) diameter when the cylinder mould dividing plate of original shellfish culture is come out of steamer by sea cucumber, also can order the cylinder mould that satisfies above-mentioned condition separately.Two circular holes be for make sea cucumber can be in cylinder mould easy on and off current, ingest and activity is provided convenience to sea cucumber.
Hang sandbag (6) in the cylinder mould bottom, prevent that impacting lower net cage in trend too drifts about.
According to the individual size of culturing sea cucumber, adjust the distance between the cylinder mould dividing plate, select the suitable etting of mesh, seedling can not be escaped from from mesh, harmful natural enemy can not enter cylinder mould from mesh.
In each cylinder mould dividing plate, place (shabby mesh bag) net sheet, be convenient to that sea cucumber adheres to and can stop undue sea cucumber, the strenuous exercise that alleviates cylinder mould of directly impacting of trend.As long-term breed (forming), can regularly clean the sea cucumber excreta on (mesh bag) net sheet.
Determine cultivation density according to the sea area natural environment, there is the breed sea area of enriching food resource in the seabed, cultivation density more greatly, otherwise then littler.General sea area through long-term shellfish culture, the seabed food resource is all abundanter, all is the fabulous food of sea cucumber as each bacterioid in the silt, various animals and plants corpse chip, shell fragment etc., and this type of is cultured each raft of sea area and hangs 50-60 cylinder mould.Under the trend influence, cylinder mould moves in the seabed, prevent that cylinder mould and cylinder mould from twining mutually, and the length of lifting rope is short as far as possible.
To select not bait throwing in be condition, children's ginseng that breed in the middle of marine, about the long 2-3cm of body, and putting 5-6 head (15 layers of dividing plate) every plate does not have bait throwing in and culture, and the length of adjustment buoyancy rope in good time in breeding process can promote that sea cucumber grows fast.Culturing the sea area with the smooth shellfish of shrimp is example, and the general depth of water is all more than 10 meters, and there is a fixed difference difference in Various Seasonal sea and seabed, and the summer high-temperature phase much more as far as possible to allow cylinder mould stop in the seabed.Spring and early summer marine organisms active, water temperature suitable, cylinder mould can be improved, that has a mind to allows various marine organisms such as young shellfish attached on the cylinder mould, replenishes how natural organic nutrient substance to sea cucumber.
If select seedling under autumn end, can hang on the buoyant raft at the opening cylinder mould sky that prop up bamboo pole summer, allow and overwork attachment inside and outside the cylinder mould, to the certain natural organic bait of sea cucumber deposit, but during toward the interior dress of cylinder mould seedling, harmful animal things such as the fish in the cylinder mould, crab, starfish be removed, behind the sea cucumber seedling of packing into, cylinder mould is sewed up with cotton rope, can effectively be prevented the invasion of sea cucumber harmful animals such as fish, crab and starfish.
Sea cucumber is an omnivore, can hang oneself at the lifting rope at cylinder mould top in marine site with good conditionsi and to support some green plantss, as sea-tangle, undaria pinnitafida etc. (specifically can with reference to the cultural method of sea-tangle and undaria pinnitafida), sea-tangle or the undaria pinnitafida company's rope (band root) selecting will grow into suitable opportunity about 1 meter are transplanted on the lifting rope at cylinder mould top, and allow the blade in growing can contact as much as possible near to cylinder mould, make sea cucumber that the chance of feed also be arranged under the cylinder mould suspended state.To more shallow, be fit to the marine site of sargassum, the growth of mouse tail algae, can be suitably like sargassum and this two plant species of mouse tail algae of eating the bottom culture sea cucumber.
Holothruian cultures through one-period (2-3), the marine eco-environment is improved, the nutriment that shellfish needs is restored, again a part of platform raft is implemented shellfish culture, in certain sea area, realize sea cucumber and shellfish with supporting, can under the prerequisite of marine ecology balance, make the healthy nuisanceless growth of two kinds of material cultures like this, reach resource and rationally utilize, to promote the sustainable development of seawater buoyancy raft net cage culture with the breed utensil.Experiment showed, that the economic benefit that produces with this apparatus and method breed sea cucumber is more than the several times of buoyant raft shellfish culture, support temporarily in the middle of being particularly suitable for.With the area, Dalian is example, mid-October, following 2-3 centimetre sea cucumber seedling can grow to 4-5 centimetre the next year 5-6 month, owing to there is not harmful animal (this time period do not have immature harmful organisms can enter cylinder mould sea cucumber is constituted a threat to), the seabed nutriment is abundant, water temperature is fit to the sea cucumber growth, and survival rate can reach more than the 90%-95%, broadcasts or stable breeding at the bottom of can directly going to the seabed this moment, the centre does not need any manual operation and any expense, and every raft of suitable operation can have a net gain 5000 yuan.As continue to form, need the bigger cylinder mould of fall the cage replacings mesh also to clean interior (mesh bag) net sheet of cylinder mould, in all processes of cage, particularly the cylinder mould exiting water process must slowly carry out, handle with care, must not too startle sea cucumber.In a single day sea cucumber is subjected to serious scaring, and the intestines that can spue cause poor growth in the future.
Preventing and kill off of stained thing will consume lot of manpower and material resources on the shellfish culture cylinder mould, annual artificial cage and manually the cleaning on the bank that will carry out 2-3 time between mature stage to cylinder mould, stained thing can cause severe contamination to the sea area in all processes that cleans, ship repeatedly comes and goes operation need consume a large amount of diesel oil, holothruian cultures then antithesis, attached to the stained thing on the cylinder mould is the fabulous natural bait of sea cucumber, need not cylinder mould is manually cleaned, and greatly reduces aquaculture cost.
This technical scheme is compared with single shellfish buoyancy raft net cage culture, can prevent and treat environmental pollution, and energy-conservation, synergy has produced unforeseeable technique effect, has represented a kind of development trend of new technology.
