Abstract
The cultivating cage has hanging rope, plummet and several layers of plates with evenly distributed string bags. Each bag contains one shellfish yorngling, and this can prevent mutual collision and bit and provide stable life environment for shellfishes. The present invention can results in high survival rate and short growth period of shellfish and is suitable for cultivating various kinds of shellfish.
Description
The present invention relates to the employed breeding cage of shellfish raft culture.
We know, the employed breeding cage of shellfish raft culture is to make the cage wall by the net sheet, and its top is provided with lifting rope, and the below is provided with dropstone, the layered discs that uniform from top to bottom some employing net sheets are made in the cage wall, encapsulation shellfish seedling on the layered discs.Owing to there is not the fixedly device of shellfish seedling on the layered discs, for attached type shellfish,, can rely on the byssus of prosperity to adhere to and fix self as chlamys farreri etc. with flourishing byssus, obtain stable living environment; And less-developed embedded type and the half embedded type shellfish of byssus, as Patinopecten yessoensis, stalwart blood clam etc., can not rely on self adhere to fixing, on layered discs, be in free state, there be not stable burying to dwell, partly bury the living environment of dwelling, one meets stormy waves, collision mutually between shellfish, cause the damage of shell outer rim, have a strong impact on growth and survival rate, particularly mutual X-bite between shellfish, often cause dead in pairs, as Patinopecten yessoensis survival rate only about 30%, seedling is formed high 10 centimetres of needs time more than 3 years of shell by the high 3-4 of shell centimetre.So this raft type cultivating cage for shellfish is not suitable for culturing the less-developed shellfish of byssus.
Purpose of the present invention provides a kind of survival rate height, and growth cycle is short, is particularly suitable for a kind of raft type cultivating cage of the less-developed shellfish of byssus.
For achieving the above object, the present invention can adopt following scheme to realize, cage wall top is provided with lifting rope, cage wall below is provided with dropstone, uniform from top to bottom some layered discs in the cage wall, its primary structure feature is: uniform some mesh bags on each layered discs, the mesh bag top is provided with opening.
The present invention is owing to uniform some mesh bags on layered discs, shellfish seedling of encapsulation has prevented that effectively shellfish from colliding mutually, X-bite in each mesh bag, be the less-developed embedded type of shellfish, particularly byssus, half embedded type shellfish provides stable burying to dwell, partly bury the living environment of dwelling, and the survival rate height can reach more than 92%, growth cycle is short, the high 3-4 of seedling shell centimetre, it is high 10 centimetres to form shell, only needs time a year and a half.The present invention is fit to culture various shellfishes, is particularly suitable for culturing less-developed embedded type of byssus and half embedded type shellfish, as Patinopecten yessoensis, and stalwart blood clam etc.

Below in conjunction with accompanying drawing, provide embodiment, the invention will be further described.
Embodiment 1: raft type cultivating cage for shellfish as shown in Figure 1, and cage wall 3 adopts the net sheet to make, and cage wall 3 tops are tied up by lifting rope 1, and lifting rope 1 can be hung raft type cultivating cage for shellfish on the raft frame.Cage wall 3 belows are provided with dropstone 5, to stablize raft type cultivating cage for shellfish.Uniform from top to bottom some circular layered discs 4 in the cage wall 3, layered discs 4 adopts the net sheet to make.Uniform some mesh bags 2 on each layered discs 4, mesh bag 2 can be hung below layered discs 4.Mesh bag 2 tops are provided with opening 6, and opening 6 is above the mesh bag 2, cut Yi Changkou on the layered discs 4.Usually under the state, opening 6 is closure state, can throw in the shellfish seedling and take out the finished product shellfish, can prevent the shellfish escape again.
Embodiment 2: raft type cultivating cage for shellfish as shown in Figure 2, and cage wall 3 is made up of at least 3 ropes, and 3 ropes compile the back up to be tied up by lifting rope 1, and the below is provided with dropstone 5.3 uniform from top to bottom some circular layered discs 4 in rope inboard, layered discs 4 adopts the net sheet to make.Uniform some mesh bags 2 on each layered discs 4, mesh bag 2 can be hung on layered discs 4.Mesh bag 2 tops are provided with opening 6, and opening 6 is above the mesh bag 2, cut Yi Changkou on the layered discs 4.Usually opening 6 is closure state, can throw in the shellfish seedling and take out the finished product shellfish, can prevent the shellfish escape again.Be provided with locking rope 7 on opening 6, behind the input shellfish seedling, Strain lock tight rope 7 can further prevent the shellfish escape.
Embodiment 3: the raft type cultivating cage for shellfish shown in Fig. 3,4, and cage wall 3 is made up of at least 3 ropes, and 3 rope tops are tied up by lifting rope 1, and the below is provided with dropstone 5.3 uniform from top to bottom some circular layered discs 4 in rope inboard, uniform some mesh bags 2 on the layered discs 4, mesh bag 2 tops are provided with opening 6.Layered discs 4 adopts reinforcing bars to make, the circular open 6 that some employing reinforcing bars of uniform welding are made on it, the circular open 6 linked network bag 2 of hanging oneself.For preventing the shellfish escape, layered discs 4 tops are provided with cover net 7, and cover net 7 adopts the net sheet to make.Lifting cover net 7 can be thrown in the shellfish seedling and take out the finished product shellfish.
