Cephalopod spawning and inhabiting device

Abstract

The invention discloses a cephalopod spawning and inhabiting device. The cephalopod spawning and inhabiting device can adapt to the characteristic that cephalopods like to spawn on attachments close to the seabed during spawning, and can effectively solve the problems that the hatching rate is reduced due to the fact that the area close to the seabed consumes oxygen due to rotten substances at the water bottom, the water flow is less, the oxygen content is low, and incubation of fertilized ova which are greatly attached together is not facilitated. The cephalopod spawning and inhabiting device comprises an inhabiting net cage, a partition plate is arranged in the middle of the inhabiting net cage, and the partition plate divides an inner cavity of the inhabiting net cage into a spawning and inhabiting cavity located below the partition plate and an incubation cavity located above the partition plate. A plurality of access channels are arranged on the side wall of the spawning inhabiting cavity; and a plurality of egg attaching devices are arranged on the inhabiting net cage, and each egg attaching device comprises a buoyancy block and an egg attaching rope located in the spawning and inhabiting cavity.

Description

technical field [0001] The invention relates to an oviposition and perch device, in particular to a cephalopod oviposition and perch device. Background technique [0002] Cephalopods (such as squid) are one of the most common swimming creatures in the ocean. In recent years, due to various reasons such as marine environmental pollution, overfishing, and destruction of spawning grounds, the production of cephalopods has declined year by year. In order to protect cephalopod resources, cephalopods have been multiplied and released and habitat protection has been achieved, and some results have been achieved; at the same time, in order to attract cephalopods to gather together to lay eggs, through the characteristics of cephalopods' preference for nests, Put artificial net cages and other nests on the seabed, and add artificial egg-attached foundations such as egg-attached ropes to the artificial net cages to provide them with habitats, spawning and fertilized egg attachment env...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a cephalopod spawning and perching device, which can not only adapt to the characteristics of cephalopods that prefer to lay eggs on attachments close to the bottom of the sea, but also effectively solve the problem of the area near the bottom of the sea. The rotting matter consumes oxygen, and the water flow is small and the oxygen content is low, which is not conducive to the hatching of a large number of fertilized eggs attached together, resulting in a decrease in the hatching rate.
