Abstract

The utility model discloses a sea cucumber ecological cultivating net cage, which is provided with a frame floating body (1) and a net bag (2) which is connected with the frame floating body (1), wherein the frame floating body (1) is connected with ropes (3) which are uniformly arranged on the frame floating body (1) and are tied to the frame floating body (1); the lower ends of the ropes (3) are connected with balancing weights (4). The net cage can be sunk to seafloor in bad weather, such as cold winter, torrid summer, strong wind, etc. to be capable of regulating water temperature suitable for the growth of sea cucumbers to a maximum extent so that the sea cucumbers hibernate or aestivate according to the habit of their own, thereby, the growth rate of the cultivated sea cucumbers is improved. The utility model can also avoid various damages caused by sea wave to the net cage and the sea cucumbers. The utility model overcomes the various problems of slow sea cucumber growth rate, high mortality, etc. existing in the existing net cages for cultivating the sea cucumbers and reduces the risk of sea cucumber cultivation. Simultaneously, the utility model has the advantages of simple structure, low cost, easy operation, etc.

Description

Netting cases for ecological culture of sea cucumber

Technical field:

The utility model relates to a kind of net cage that is used to culture sea cucumber, especially a kind of netting cases for ecological culture of sea cucumber of suitable sea cucumber habit of growth.

Background technology:

The sea cucumber of self-sow generally lives in 2～20 meters dark seabeds, and its existence temperature is-1～30 ℃.When water temperature was 10～15 ℃, the food ration of sea cucumber was big, growth is fast, is the vegetative period of sea cucumber; When water temperature was lower than 3 ℃, the sea cucumber food ration reduced, and is in the semidormancy state, is hibernation period; And water temperature is when being higher than 17～19 ℃, and the food ration of sea cucumber reduces too, is in resting state, is estivation period.At present, people carry out the breed of sea cucumber in many ways, and one of them is to use the cage culture sea cucumber.Existing net cage generally all has the framework buoyancy aid, is connected to mesh bag below the framework buoyancy aid, sea cucumber is placed in the mesh bag culture.There is following disadvantage with this kind cage culture sea cucumber:

1. because the arbitrarily lifting of existing net cage is subjected to condition restriction such as manufacture craft, cost of manufacture, and its mesh bag height has only 5 meters in addition, sea cucumber can only live in the following 5 meters dark mesh bags of the water surface like this.The water temperature of 5 meters depths and water surface temperature differ very little, it is longer to make that water temperature in winter (Bohai Sea Area) is lower than 3 ℃, summer, water temperature was higher than time of 17～19 degrees centigrade, prolonged hibernation or the aestivation time of sea cucumber artificially, shortened the vegetative period of sea cucumber, the growth rate of sea cucumber is slow.

2. during as bad weathers such as strong wind, net cage can not arbitrarily sink and hide stormy waves, and net cage itself is very easily damaged by stormy waves; Sea cucumber in the mesh bag also can be injured because of stormy waves impact appearance, and the erosion of various germs will cause sea cucumber death, have a strong impact on the survival rate of sea cucumber.

Summary of the invention:

The utility model is in order to solve that existing net cage can not sink and the various technical problems brought, and a kind of netting cases for ecological culture of sea cucumber of suitable sea cucumber habit of growth is provided.

Technical solution of the present utility model is: a kind of netting cases for ecological culture of sea cucumber, and there is framework buoyancy aid 1 to reach the mesh bag 2 that joins with framework buoyancy aid 1, be to be connected to the balanced rope 3 that is provided with on the framework buoyancy aid 1, the lower end of rope 3 is connected to balancing weight 4.

Described rope 3 can pass the hole 5 on the framework buoyancy aid 1, on the rope 3 of 5 upper ends, hole tight locking button 6 is arranged.

The utility model is compared with prior art, its biggest advantage is the winter in cold, hot summer, and during bad weather such as strong wind, can be with the net cage dive to the seabed, can in maximum magnitude, regulate the water temperature that adapts to the sea cucumber growth, make habit hibernation or the aestivation of sea cucumber, improve the growth rate of culturing sea cucumber according to oneself; Can avoid wave to net cage and various infringements that sea cucumber brought again, overcome various disadvantages such as the existing sea cucumber growth rate of existing cage culture sea cucumber is slow, lethality height, reduce the risk of culturing sea cucumber.That the utility model also has simultaneously is simple in structure, cost is low, advantages such as processing ease.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the user mode schematic diagram of the utility model embodiment.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: with existing net cage, the mesh bag 2 that framework buoyancy aid 1 is arranged and join with framework buoyancy aid 1, framework buoyancy aid 1 can be hollow tubular structures, also can be solid light plastid.Be to be connected to the balanced rope 3 that is provided with on framework buoyancy aid 1, the balanced purpose that is provided with is the balance that guarantees framework buoyancy aid 1 and mesh bag 2, and the lower end of rope 3 is connected to balancing weight 4, and rope 3 length should be longer than the degree of depth in seabed.The method that binds rope 3 at framework buoyancy aid 1 is multiple again, ties up on the framework buoyancy aid 1 as can directly rope 3 being twined; Also can on framework buoyancy aid 1 clamping device be installed, rope 3 places in the clamping device, fixing as required or payout 3; Also can on framework buoyancy aid 1, install and be used for fixing or the winch of payout 3.The simplest and maneuverable structure is that processing portals 5 on framework buoyancy aid 1, and rope 3 passes hole 5, on the rope 3 of 5 upper ends, hole tight locking button 6 is set, and as various snap rings, buckle etc., also can as shown in Figure 1 rope 3 be got fixing knot.User mode is as shown in Figure 2: when calm and temperature were fit to, balancing weight 4 sank to the bottom of the sea, and framework buoyancy aid 1 fixedly swims on the water surface, fixed with static line 7; Winter, summer or when meeting stormy waves, breeding piece 4 can be risen, the weight that increases the weight of net cage makes net cage sink down into the seabed to overcome buoyancy.

Claims

1. a netting cases for ecological culture of sea cucumber has framework buoyancy aid (1) to reach the mesh bag (2) that joins with framework buoyancy aid (1), and it is characterized in that: framework buoyancy aid (1) is gone up the rope (3) that system is connected to balanced setting, and the lower end of rope (3) is connected to balancing weight (4).

2. netting cases for ecological culture of sea cucumber according to claim 1 is characterized in that: described rope (3) passes the hole (5) on the framework buoyancy aid (1), on the rope (3) of hole (5) upper end tight locking button (6) is arranged.
