Abstract

The invention relates to mollusk, special cultural method and equipment as oyster.Oyster is placed in the container that can seep water, and container is placed in the suitable waters oyster is raised.Make the container rotation oyster movable in the container of being everlasting.Rotation is caused by machinery or tidal water movement.

Description

Molluscan breed

The invention relates to mollusk, particularly the cultural method of oyster class and equipment.

Current known oyster class cultural method and equipment have following shortcoming:

1. when being placed on oyster in the supporting structure arbitrarily, as when being with in the fence of stake, oyster can be gathered mutually.So just, cause shell distortion, be difficult to sorting and peel off, thereby need to increase extra labour their bunch clump is separated.And shell below can't be fed, so growth is undesired.

2. the bay that morning and evening tides is arranged is the excellent environment of supporting oyster.But in this environment, silt can deposit on shell.Silt not only lowers the breed progress of oyster, thereby slows down their growth, and mud worm (mud worm) is gathered with other diseases grow, and is very harmful to the growth of oyster.

3. the shell of young oyster is quite soft, by the fish fragmentation, meat is eaten up easily.The loss that fish are caused can be up to 80%.

The objective of the invention is to overcome one or more above-mentioned shortcomings.

Generalized form of the present invention comprises molluscan cultural method, and its step comprises the molluscan young is placed in the container that can seep water, and container support in the water of culturing, and is regularly moved or shakes container, makes mollusk movable in container.

The form of another one broad sense of the present invention comprises a kind of infiltration container, in order to hold some mollusks, this container can be supported on cultures in the molluscan water, one device is arranged in the container, container itself is shaken, so that all mollusks inside making can both be movable.

Do following narration referring now to accompanying drawing, accompanying drawing thes contents are as follows:

Fig. 1 represents to remain on the container of the above a kind of form of rising tide line.

Fig. 2 represents to be immersed in the same container than below the high-water mark.

Fig. 2 A represents to have the similar containers of different buoyancy.

Fig. 3 is a similar containers.

Fig. 4 represents to reach the other method of shaking.

Fig. 5 represents that another kind shakes method.

Fig. 6 and 7 expression another kinds shake method.

Fig. 8 and 9 expression another kinds shake method.

Figure 10 represents that another kind shakes method.

Referring to Fig. 1 and 2, container 1 has net wall or sieve wall 2.Container 1 usefulness pillar 4 and cross bar 5 are supported in the top or water of water 3.Container 1 rotatably is contained on the cross bar 5 with ring 6.There is a showy part 7 to be fixed on the container, preferably relative with ring 6.Floating part 7 can be integrally formed with the end wall 2a of container 1, shown in Fig. 2 A.

The height of pillar 4 can be regulated, so the height of container 1 can regulate thereupon, therefore back water level depression on the ebb, and container 1 just is exposed at the outside of water 3, as shown in Figure 1.At the incoming tide container 1 become partly under water, or all under water, as shown in Figure 2.Along with the rise and the whereabouts of tidewater, container 1 rotatablely moves up and down around cross bar 5 and ring 6 owing to the effect of the part 7 that floats.

The rotation of container 1 has caused clocklike rolling of mollusk 8.

Fig. 3 has and Fig. 1 and the similar number of marking on a map of Fig. 2.At the number of marking on a map 9 places, different whirligigs is arranged.

Fig. 4 represents the fluctuation along with tidewater, because the effect of float 7, thereby the container that can move up and down around the hinge of connecting struts 4.

In Fig. 5, container 1 rotatably is contained in outside 11 on the pillar 4.A propeller or like instrument 12 are arranged, utilize the effect of the tidewater of turnover, make container 1 rotation.

Fig. 6 represents the container similar to Fig. 1 and Fig. 2, but it shakes by the effect of tidewater on blade 13 of turnover.

Fig. 8 and the 9 expressions arrangement similar to Fig. 5, but rotation is what to reach by the effect of tidewater on blade 14.

Figure 10 represents the arrangement similar to Fig. 8 and 9, but container 1 has different shapes and different blades 15.

Concept of the present invention, importantly mollusk does regular activity in water. Preferably by the shaking of container, reach purpose of the present invention thereby produce molluscan slow rolling.

Because shell is done regular activity, thereby can be not adhered to one another, also can not adhere at chamber wall. Therefore shell can not be out of shape, and owing to the time of mollusk contact aquaculture water is many, so growth fraction is very fast.

Because mollusk water turning in around rolls, so the silt height breaks away from from animal body. Can also improve so molluscan feed ability, thereby further improve the speed of growth.

" infiltration container " word refers to hollow body, and is preferably cylindrical, and at least partly wall body (preferably cylindrical wall) is made with gauze or screen cloth, passes through in order to water. The pore size of screen cloth, normally at water by the flowing freely of container, and compromise between molluscan size and growth age three factors, to prevent that fish are to the invasion and attack of shell.

Though the present invention is described with reference to natural tidewater situation, is applicable to method and the facility propagated artificially too.Water level in the feeding slot can raise or reduce, and can be rotated by the effect of float 7 with Bedpan 1.

And water can move by feeding slot, thereby the facility of Fig. 5 shown in Figure 10 worked.

It is contemplated that, can for example 1 container be fixed in the tank that molluscan activity is by the nature that rises and falls or mechanical flowing, or common mechanical rotation causes.

Method of the present invention, consideration be the molluscan equipment of narrating above of breed." rotation " speech not necessarily must refer to the rotation in wholecircle week.

Be as an example about narration of the present invention above, can see that can to use the production shape neat, anosis fast mollusk grows.

Claims

1, includes a permeable container in the mollusk cultivation equipment, this container can be used for holding some mollusks, and can be supported in the molluscan waters of breed, it is characterized by a device is arranged in this container, can make and itself shake or rotate, so that make any mollusk activity of receptacle.
