An egg-attached rope-type squid spawning attachment device

Abstract

The invention discloses an egg-attached rope-type squid spawning attachment device, which aims to provide a squid eggs that will not affect the spawning efficiency and can effectively prevent a large number of squid eggs from being stacked together, resulting in a large number of squid eggs being wrapped in the middle. The squid eggs are stunted or even rotten to death, which seriously reduces the survival rate of hatching. The egg-attached rope-type squid spawning attachment device. It includes a counterweight base; a floating frame; a supporting frame, which is suspended in the water under the buoyancy of the floating frame, and the supporting frame includes a horizontal top rod and a horizontal bottom rod parallel to the horizontal top rod; an isolation cage, an isolation cage Fixed on the support frame; a number of self-adjusting egg attachment mechanisms, the self-adjusting egg attachment mechanism includes the upper guide wheel that is rotated on the horizontal push rod, the lower guide wheel that is rotated on the horizontal lower rod, and the upper guide wheel that surrounds the With the ring-shaped egg-attached rope on the lower guide wheel and a number of self-adjusting devices distributed in the right cavity sequentially from top to bottom.

Description

technical field [0001] The invention relates to an attachment device for squid spawning, in particular to a rope-attached egg attachment device for squid spawning. Background technique [0002] Cuttlefish need to lay their eggs on attachments, and they have higher requirements for attachments. Usually, they are selected where the fixation is firmer and the surface is smoother. In the sea area of ​​the spawning ground, due to the severe shortage of gorgonians, the main spawning attachments of squids, it is far from meeting the needs of squids for spawning. As a result, many fertilized eggs are attached to some tender branch-shaped seaweeds, and the squids attached to the seaweeds The fertilized eggs are easy to fall off when encountering the impact of water flow, or even fall off in a string. Once the squid fertilized eggs fall off and sink into the seabed mud, it will cause the death of the squid fertilized eggs and seriously reduce the hatching rate of the squid fertilized ...

In the sea area of ​​the spawning ground, due to the severe shortage of gorgonians, the main spawning attachments of squids, it is far from meeting the needs of squids for spawning. As a result, many fertilized eggs are attached to some tender branch-shaped seaweeds, and the squids attached to the seaweeds The fertilized eggs are easy to fall off when encountering the impact of water flow, or even fall off in a string. Once the squid fertilized eggs fall off and sink into the seabed mud, it will lead to the death of the squid fertilized eggs and seriously reduce the hatching rate of the squid fertilized eggs. Therefore, while strengthening the work of proliferation and release , the repair of spawning attachments must be carried out simultaneously

[0003] For this reason, a large amount of artificial egg-attached bases are applied to increase the attachments of squid spawning, but the inventor found in the long-term work and investigation that the number of eggs per string of squid spawning is extremely large, and the artificial egg-attached bases Each string of eggs can reach more than 500, and the number can even reach several thousand. A large number of squid egg strings often have a large number of squid eggs stacked together, causing a large number of squid eggs wrapped in the middle to be stunted or even The problem of rotting and death seriously reduces the hatching rate, which has caused serious obstacles to the reproduction of squid resources in natural sea areas

[0004] In order to solve this problem, some inventors have improved the artificial egg-attachment of squid. For example, the Chinese patent publication number is CN110352881A. The name of the invention is a device for artificially inducing squid to lay eggs. The application is passed Disturb the bar to drive away the squid, to control the number of eggs in each string of squid eggs, so as to avoid a large number of squid eggs stacked together, so that not only will the parent squid in the spawning startled, but also affect the quality of the squid. Spawning efficiency; moreover, squid need to constantly change the spawning site (generally, the spawning capacity of a squid reaches several thousand), which will affect the spawning efficiency of squid; on the other hand, it will also greatly reduce the The number of string eggs makes the demand for the number of artificial egg bases increase sharply
