Description

Device for inducing cuttlefish to gather and lay eggs
Technical Field
The invention relates to an artificial seabed structure, in particular to a device for inducing cuttlefish to gather and spawn.
Background
At present, in a spawning ground sea area, 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.
On the other hand, 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-attaching 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 a large number of cuttlefish eggs stacked together, so that a large number of cuttlefish eggs wrapped in the middle are delayed in development and even rotten and die, the hatching rate is seriously reduced, and serious obstacles are caused to the propagation of cuttlefish resources in natural sea areas.
