Egg attaching rope type cuttlefish egg laying attaching device

Abstract

The invention discloses an egg attaching rope type cuttlefish egg laying attaching device. The egg attaching rope type cuttlefish egg laying attaching device does not influence cuttlefish egg laying efficiency and can effectively solve the problems that a large number of cuttlefish eggs are stacked together to cause slow development and even rotting death of a large number of cuttlefish eggs wrapped in the middle, and the incubation survival rate is seriously reduced. The device comprises a balance weight seat, a floating frame, a supporting frame, an isolation net cage and multiple self-adjusting egg attaching mechanisms. The supporting frame is suspended in water under the buoyancy effect of the floating frame, and the supporting frame comprises a transverse top rod and a transverse bottom rod parallel to the transverse top rod; the isolation net cage is fixed on the supporting frame; and each self-adjusting egg attaching mechanism comprises an upper guide wheel rotationally arrangedon the transverse top rod, a lower guide wheel rotationally arranged on a transverse lower rod, an annular egg attaching rope surrounding the upper guide wheel and the lower guide wheel, and a plurality of self-adjusting devices sequentially distributed in a right cavity 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
