Abstract
The invention relates to a shellfish breeding method, in particular to a shellfish breeding method by arranging a platform raft in different water layers. A breeding water layer of a shellfish variety is determined according to habits of the bred shellfish, water temperature and water temperature stability of the breeding environment, baits, harmful organisms and the like. Water depth of the platform raft arranging area is 25-60m, a peg cable of the platform raft is connected with a raft body, two ends of the peg cable is fixed to a seabed, 2-3 layers of buoyancy forces are arranged on the raft body, the bred shellfish is filled in a breeding cage, the breeding cage is tied to a lifting rope, and is tied to the raft body through the lifting rope, and breeding water layers are changed by moving the breeding platform raft or adjusting height of the breeding platform raft so as to meet requirements of different shellfish varieties. According to the invention, a new shellfish breeding pattern is created; sea area resources are completely and effectively utilized through changing the water layers; an environment with relatively stable water quality and water temperature is provided for the shellfish; intermediate breeding survival rate and breeding speed of seedlings are increased; the scale of a single platform raft is expanded; breeding quantity is increased; and the shellfish breeding method has a important significance for the upgrade of shellfish industry.
Description
Technical field
The present invention relates to a kind of shellfish culture method, especially a kind of change water layer platform raft shellfish culture method.
Background technology
At 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 breeding way 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 implemented in the neritic area of offshore, cultures the depth of water of water layer about 5-8 rice, 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: become water layer platform raft shellfish culture method, confirm the water layer of putting in a suitable place to breed of breed variety according to cultivated shellfish biological nature and breeding environment water temperature and factors such as stability, bait and harmful organisms thereof.The platform raft setting area depth of water is at 25～60 meters, and platform raft short wooden stake cable and raft body connect together, and the seabed is fixed at two ends; Raft is provided with 2～3 layers of buoyancy on one's body, and buoyancy is connected with the raft body through floating well rope, and the buoyancy number is as the criterion to guarantee platform raft balance; Cultivated shellfish is packed into and is cultured in the cylinder mould or lie on the hanger shellfish rope; Breed cylinder mould or hanger shellfish rope hang over through lifting rope system on one's body the raft, and breed cylinder mould or hanger shellfish rope are in below the raft body and are to hang between the buoyancy, and the effective length of lifting rope is 1 meter; The spacing of culturing cylinder mould or hanger shellfish rope is a 0.6-1.2 rice; Change according to breeding environment in the shellfish culture process, move or adjust the platform raft of cultivation altitude conversion and put water layer in a suitable place to breed, to satisfy the breed variety demand.
Distance is more than 30 meters between the raft body.
The company's of setting cable between the platform raft.
Length of peg cable is provided with according to the actual depth of water, and length of peg cable is 3:1 with the ratio of the actual depth of water.
Said raft is provided with layer 2-3 buoyancy on one's body, and raft is provided with the buoyancy that the floating well rope of different length connects on one's body at interval.
Many rafts are cultured and are divided into groups, and 10～20 is one group, whenever organize a performance between the raft apart from more than 100 meters.
Raft is provided with raft body button on one's body, in order to fixing lifting rope, thus fixing spacing of culturing cylinder mould or hanger shellfish rope.
Can find out that by above technical scheme the present invention has following beneficial effect: started the new model of shellfish culture,, fully effectively utilized the marine site resource through becoming water layer according to cultivated shellfish habit and environmental change factor conversion water layer; Deep water sea area resource below 25 meters particularly; 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 enlarges the scale of single raft, has increased breed quantity, and is significant to the shellfish industrial upgrading.
