Description
Technical Field
The invention relates to a gorgonian transplanting device, in particular to a gorgonian transplanting device for attracting cephalopods to lay eggs.
Background
Cephalopods (e.g., cuttlefish) are the most common creatures in the ocean, but in recent years, the production is scarce due to excessive fishing by fishermen, destruction of spawning sites, and the like. Therefore, the work of reproduction, proliferation and releasing of cephalopods is already carried out, and certain achievements are obtained; however, the number of the current gorgonia is seriously insufficient, and the gorgonia can be used as a natural habitat of cephalopods, has the function of providing a natural spawning site for the cephalopods, and has important significance for the seabed ecological environment and the reproduction of the cephalopods.
On the other hand, in the sea area of a spawning ground, as the number of main egg attachment gorgonian of the cuttlefish is seriously insufficient, the requirement of parent cuttlefish for egg laying can not be met, therefore, a large amount of artificial egg-attaching bases are applied to increase the egg attachment of the cuttlefish; however, the inventor finds that cuttlefish prefers to lay eggs on attachments near the seabed, for example, the lower parts of the wicker branches of the gordonia pseudoptera are attached to lay eggs, or attachments within 60 cm near the seabed in an artificial egg-laying base are attached to lay eggs (for example, lay eggs on egg-laying ropes within 60 cm from the seabed); however, the artificial egg-attaching base put in at present often does not consider the point, but the egg-attaching position of the egg-attaching base is enlarged by utilizing the depth space, for example, the length of the egg-attaching rope of the artificial egg-attaching base of the egg-attaching rope type in the depth direction is longer and generally exceeds 1 meter, which seems that the attachment of cuttlefish eggs can be increased by the longer egg-attaching rope, and the requirement of the parent cuttlefish for laying eggs is met by utilizing the depth space; but actually, the method does not have the corresponding effect, and the deep space cannot be utilized to meet the requirement of the parent cuttlefish for spawning. In addition, the number of eggs of each string of cuttlefish when laying eggs is extremely large, the number of eggs of each string of cuttlefish on the egg-attached base can reach more than 500, more eggs can even reach thousands of eggs, and the strings of cuttlefish eggs with extremely large number often have the phenomenon that a large number of cuttlefish eggs are stacked together, so that a large number of cuttlefish eggs wrapped in the middle are delayed in development and even rotten and dead, the hatching rate is seriously reduced, and serious obstacles are caused to the propagation of cuttlefish resources in natural sea areas.

3. The gorgonian transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein there are a plurality of artificial egg-attaching devices, and each artificial egg-attaching device is sequentially and equidistantly distributed along the length direction of the perching channel.
4. The pseudopterogorgia transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein the top plate has a plurality of upper mounting holes on the upper surface, and pseudopterogorgia culturing blocks are also mounted in the upper mounting holes.
5. The pseudopterogorgia transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein a plurality of upper perching holes are provided on the lower surface of the top plate.
6. The pseudopterogorgia transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein the side perching holes are blind holes.
7. The pseudopterogorgia transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein the pseudopterogorgia culturing block in the lower mounting hole is fixed in the lower mounting hole by a bolt.
8. The pseudopterogorgia transplanting device for attracting cephalopoda to lay eggs according to claim 1, wherein the base is a concrete base.
