Abstract
The invention relates to a shellfish cultivation method, in particular to a shellfish cultivation method using a deep-water stand raft. Breeding water layers for culture breeds are determined according to factors, such as biological habits of cultured shellfish, water temperature of culture environment, stability of the water temperature of the culture environment, feed, harmful organisms and the like. Water of a stand raft arrangement area is 30-60m deep. Ropes on fixed pegs are connected with a raft body, and two ends of each rope are fixed at the seabed. The whole raft body is held down on the seabed through a plurality of weights at intervals. Buoys are disposed on the raft body. One end of each shellfish cultivation cage is suspended to the raft body through a suspension rope, and one buoy is tied to the other end of each shellfish cultivation cage through a floating rope. The effective length of each suspension rope is 0.6-1.2m. A new mode of shellfish culture is initiated in the method, the advantage of water temperature difference of deep water more than 16m deep is fully utilized, a water environment with stable temperature is provided for shellfish, intermediate breeding survival rate of fry and development speed of the fry are increased, sea resources are fully and effectively utilized, and upgrade of the shellfish industry is positively promoted.
Description
Technical field
The present invention relates to a kind of shellfish culture method, especially a kind of deep water platform raft shellfish culture method.
Background technology
[0002] present; In China's Coastal Areas; The breed of shellfish development has become the sea area emphasis aquaculture industries such as Liaodong Peninsula, chang-dao of northern China rapidly, and the shellfish culture mode mainly adopts the end to broadcast propagation (propagation of releasing) and suspended longline farming dual mode.Broadcast the propagation mode and has ensured biology self-sow in natural environment at the end; As a kind of healthy aquaculture pattern, make full use of the self-purification capacity of seawater, guaranteed the safety and the quality of aquaculture organism; And advantages such as natural environment variable effects such as stormy waves are less; But not all place all is fit to, and must be silt particle or the mixed quality bands of sand such as water temperature is suitable, mostly the seabed is cay, sandstone substrate, and marine sites such as ooze substrate can't be carried out the end and broadcast propagation.Therefore be suitable for Patinopecten yessoensis the release sea area of propagation substrate condition of water temperature condition and not being suitable for of growing for possessing, carry out floating raft type and hang down that to culture be the another kind of mode that Patinopecten yessoensis is produced.And suspended longline farming is all implemented in the neritic area of offshore, cultures the depth of water of water layer about 5～8 meters, receives harmful organisms such as water temperature, assorted algae adhere to, mussel, and disaster factors influence such as typhoon is serious, and the seed phenomena of mortality are very serious during aestivating especially in recent years.
In sum, how to guarantee that the shellfish healthy aquaculture can fully effectively utilize the marine site resource again, becomes the problem that the scallop culture industry is demanded urgently answering.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of healthy ecology scale shellfish culture method of fully effectively utilizing the marine site resource.
Technical scheme of the present invention is: deep water platform raft shellfish culture method, confirm that according to cultivated shellfish biological nature and breeding environment water temperature and factors such as stability, bait and harmful organisms thereof breed variety puts water layer in a suitable place to breed.The platform raft setting area depth of water is at 30～60 meters, and short wooden stake cable and raft body connect together, and the seabed is fixed at two ends; Whole raft body is pressed in the seabed at interval with a plurality of weights; Guarantee that raft does not move in the seabed, raft is provided with on one's body and floats a kind buoyancy, floats kind buoyancy and floats on the sea and through floating well rope and be connected with the raft body.Shellfish culture cylinder mould one end hangs over through lifting rope on one's body the raft, and the other end is through floating buoyancy of well rope tying-up, and the effective length of lifting rope is 0.6～1.2 meter.Between mature stage, carry out the inspection management.
The platform raft is indirectly greater than 30 meters.
Length of peg cable is provided with according to the actual depth of water, and length of peg cable and actual depth of water ratio are 3:1.
Raft is provided with raft body button on one's body, in order to fixing lifting rope, thus fixing spacing of culturing cylinder mould.
Can find out that by above technical scheme the present invention has following beneficial effect: the new model of having started shellfish culture; Make full use of the water temperature difference advantage of profundal zone below 16 meters; Reduce adhering to of fouling organism, assorted algae, thereby reduce the frequency of falling the cage in the production process, reduced personnel labor; Save lot of manpower and material resources; Simultaneously more solve the prior art shellfish culture and cross the summer problem, for shellfish provides comparatively stabilizing water quality water temperature environment, raising seed centre breeds survival rate and seed is formed speed; The present invention expands platform raft breeding way to the Deepwater Open Sea zone, has enlarged space, shellfish culture marine site, fully effectively utilizes the marine site resource, and the scale of single raft of expansion, increased breed quantity, the shellfish industrial upgrading is had positive impetus.
Embodiment
With specific embodiment the present invention is done further explain below.
