Description

Sea urchin breeding device that grows seedlings

Technical Field

The invention relates to the technical field of sea urchin culture equipment, in particular to a sea urchin seedling culture device.

Background

Sea urchins are deeply popular with people of all countries in the world due to delicious taste and high nutritional value, and naturally collected sea urchins can not meet the market demand for a long time, so that the culture interest and the culture area of sea urchins are increasing year by year in the world. The Liaoning, Hebei, Shandong and other north provinces in China are important cultivation places for sea urchin cultivation, and the cultivation mode of sea urchins in China is mainly raft cultivation.

The process of culturing the young sea urchins is the later stage of sea urchins breeding, and refers to the process of culturing the abnormal young sea urchins into sea urchins with the shell diameter of more than 2 cm. At present, the method for culturing the large-scale sea urchin families and young sea urchins mainly comprises the following steps: during the period that the shell diameter is less than 3mm, adopting a seedling original pond for cultivation, feeding benthic diatom (attached to a corrugated plate) and ulva, and respectively changing water and feeding in each seedling pond; and after the diameter of the shell is larger than 3mm, collecting sea urchin seedlings from a seedling raising original pond, putting the sea urchin seedlings into a plastic net cage for cultivation, tying rods on two sides of the net cage, then erecting the net cage on the pond, and feeding baits such as ulva, kelp and the like. The seedling cultivation method has the following defects: 1. the existing raft culture mode has the problems that a great amount of manpower and material resources are consumed by manual operations such as bait (fresh seaweed) feeding, cage reversing, density and the like, and the problems reduce the enthusiasm of fishermen for culturing sea urchins. 2. Seedlings need to be transferred in the culture process, and the transfer operation causes great damage to the seedlings, so that the survival rate is low. 3. The moving range is small before the diameter of the sea urchin shells is 3mm, the original pool for raising seedlings is large, so that the growth environment among individuals in a family is inconsistent, and if ulva is fed, seedlings far away from a feeding point cannot eat bait.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1-4, the utility model provides a sea urchin seedling raising and breeding device, which comprises a tuck net body 1 with an upper end open, wherein a support frame 2 is installed on the bottom surface of the tuck net body 1, and the support frame 2 is a rectangular frame and is fixed on the bottom surface of the tuck net body 1 and is used for supporting the bottom surface of the tuck net body 1; the support frame 2 is fixedly connected with the net bag body 1 through a nylon rope. The edge of the opening at the upper end of the net bag body 1 is provided with a floating frame 3 for supporting the net bag body 1 to float on the water surface; pocket form body 1 is the tetragonal body, sews up the connection through the nylon rope between two adjacent sides, and sews up four apex angle fixed connection of department bottom through connecting rope and support frame 2 respectively. Use the utility model discloses a sea urchin breeding device of growing seedlings when breeding, put into the aquatic with it, support frame 2 sinks into the water along with the action of gravity, it floats on the surface of water to float frame 3 by the action of water buoyancy, only need put in sea urchin seedling and go into the string bag body 1 in, through throwing and eating bold kelp, sea urchin can automatic absorption move about at the surface of kelp gathering in the farming process, it is convenient to make whole sea urchin grow seedlings the farming process, and the circulation that drives whole water through the flow of circulation flow water, the farming in-process need not wash the change, time saving and labor saving, show and reduce the cost of farming, improve the sea urchin and grow seedlings and breed the survival rate.

Float frame 3 also is the rectangle frame for support the upper end opening of fixed net bag form body 1, net bag form body 1 is net graticule mesh pocket body 1 that is woven by the nylon cord, the net bag form body 1 that is located the upper end opening part with float frame 3's upper surface cover, when using the utility model discloses a sea urchin grows seedlings and breeds in-process when needing to shift the seedling, the operator only needs earlier to lift up hand float frame 3 through one and holds up whole sea urchin seedling breeding device back, and one side of support frame 2 is upwards lifted up to another hand, can be in order to draw out the transfer with sea urchin seedling and kelp through float frame 3 on the surface net bag form body 1 department together, whole process operation is simple and convenient swift, simple and easy, and almost not damaged to the sea urchin seedling, is showing and is improving the success rate.

Still set firmly stainless steel couple 4 on the floating frame 3, on the nylon rope that 1 upper end opening part edge of string bag body was connected through with stainless steel couple 4 was fixed in floating frame 3, further ensured the steadiness that string bag body 1 and floating frame 3 were connected, ensured that sea urchin seedling is bred and the transfer process goes on smoothly, sparingly breeds the cost.

Support frame 2 is the same with the shape that floats frame 3, and the two all is four angles rectangle frames for the fillet, and support frame 2's size of a dimension is less than the size of a dimension that floats frame 3, the convenience that the operator of being convenient for used on the one hand of this kind of structure, and on the other hand can further simplify the transfer seedling process, makes its transfer convenient and fast more.

Preferably, the floating frame 3 is a hollow plastic pipe with the outer diameter of 5-10 cm; when the support frame 2 is a solid stainless steel pipe with the diameter less than or equal to 10mm, the use effect is optimal, and an operator can lift and put down conveniently and quickly, so that the time and labor are saved, and the maintenance is convenient.

The mesh size of the net pocket-shaped body 1 is 100-200 meshes, and the mesh is too large, so that sea urchin seedlings cannot be effectively borne, and cannot grow normally in the sea urchin seedling culture device; the mesh is too small, and due to the tension of water, the mesh is easy to hang a membrane, water inside and outside the net bag is difficult to circulate, and metabolites of sea urchins in the net bag cannot be discharged normally, so that the water quality is polluted, and the growth speed of the sea urchins is influenced. The mesh openings with the specifications can effectively prevent the loss of sea urchin seedlings, can ensure the natural exchange of water inside and outside the net bag, and is favorable for promoting the growth speed of sea urchins.

To sum up, the utility model discloses a sea urchin breeding device that grows seedlings, device simple structure, cost of manufacture are low, and convenient to use is swift, throws edible convenience, labour saving and time saving, and survival rate of seedling is high, promotes the seedling growth, shifts the seedling in-process and is low to the seedling damage degree, the biggest survival rate of ensuring of seedling.
