Description

Artificial nest for cephalopods
Technical Field
The utility model relates to a spawning and inhabiting device, in particular to a cephalopod artificial nest.
Background
Cephalopods (e.g., cuttlefish) are one of the most common swimming creatures in the ocean, and with the recent years, the yield of cephalopods has been decreasing year by year due to various causes such as marine environmental pollution, over-fishing, and destruction of egg laying sites. In order to protect cephalopods resources, the cephalopods are subjected to proliferation and releasing and habitat protection, and certain results are obtained; meanwhile, in order to attract cephalopoda animals to gather together for spawning, through the characteristic that cephalopoda prefers nests, nests such as artificial net cages are put in the sea floor, artificial egg-attaching bases such as egg-attaching ropes are additionally arranged on the artificial net cages, and inhabitation, spawning and fertilized egg attachment environments are provided for the cephalopoda animals.
On the other hand, in the nest combining the current artificial net cage and the egg-attached rope, although the habitat can provide habitation, egg laying and fertilized egg attachment environment for the cephalopods, because the cephalopods prefer to lay eggs on attachments close to the seabed when laying eggs, a large amount of fertilized eggs are attached to the egg-attached rope close to the seabed (generally attached to the egg-attached rope within 60 cm away from the seabed), and in the area close to the seabed, because decaying substances at the bottom consume oxygen, and water flow is low, the oxygen content in the area close to the seabed is low, so that the hatching of a large amount of attached fertilized eggs is not facilitated, and the hatching rate is reduced. On the other hand, the dropped fertilized eggs directly sink into the seabed sludge, so that the fertilized eggs of the cuttlefish die.
SUMMERY OF THE UTILITY MODEL
The first purpose of the utility model is to provide a cephalopod artificial nest which can attract the cephalopods to gather and provide habitat, spawning and fertilized egg attachment environments for the cephalopods.
The second purpose of the present invention is to provide an artificial cephalopods, which not only can adapt to the characteristics of cephalopods that favor laying eggs on attachments near the seabed during laying eggs, but also can effectively solve the problem that the incubation rate is reduced because decaying substances near the seabed consume oxygen, and the water flow is low, the oxygen content is low, and the incubation of a large amount of attached fertilized eggs is not facilitated.
The technical scheme of the utility model is as follows:
the utility model provides a cephalopodium artificial nest, includes inhabitation box with a net and a plurality of ovum devices that attach, inhabitation box with a net's middle part is equipped with separates the otter board, separates the otter board and will inhabit the inner chamber of box with a net and separate the cavity of inhabitation of laying eggs that the otter board below was separated and be located the last cavity of separating the otter board top, the mesh intercommunication of separating the otter board is laid eggs and is inhabited cavity and last cavity, attach the ovum device including being located the ovum rope that attaches that the cavity was perched in laying eggs, be equipped with a plurality of access ways on the lateral wall of the cavity of perching in laying eggs. The scheme utilizes the characteristic that cephalopods like drilling, and a plurality of access channels are arranged on the side wall of the spawning inhabitation cavity to attract the cephalopods to enter the spawning inhabitation cavity through the access channels, so that the cephalopods are attracted to the outside, and an environment for inhabitation, spawning and fertilized egg attachment is provided for the cephalopods.
