Embodiment Construction

[0014] like figure 1 The most basic structure of the present invention as a monomer comprises a frame 1 positioned at the middle as a support and fixation, and at least two web sheets 3 with netting 2 fixed alternately on the periphery of the upper and lower frames of the frame 1, and a shielding body 4 A sticker cover is fixed on top of it. Above-mentioned frame 1 is made square frame shape or cylinder frame with high-strength polyethylene material. like figure 2 It is a cylindrical frame with a support rod in the middle. The web sheet 3 supports the net clothing 2 by two support rods.

[0015] like Figure 4 , Figure 5 , considering the compact structure and enlarging the foundation area, the above-mentioned multiple basic structures can be combined horizontally on the steel structure bottom frame 5; it can also be further vertically stacked on the basis of the horizontal combination, as long as the steel structure bottom frame 5 is fixed at the bottom . Therefore, ...

Abstract

The invention relates to an cuttlefish attaching ledge rock with net flexible structure, comprising: the supporting frame in the middle, the net piece at least two of which posses net cloth equipped in the perimeter up and low frame, and the barrier fixed on the frame. The said monomers can combine horizontally or overlays vertically when considering the compact structure and enlarging the attaching area. The said barrier is made of canvas or plastic with holes in the middle, and it provides proper shadow. The attaching ledge rock made of high-intensity polyethylene is the flexible structure, which can prevent the enemy creature approach when swinging under the action of current or wave. The cuttlefish ovum attaching rate on the attaching ledge rock is high and the survival rate is high, which can increase the cuttlefish production effectively, the economic benefit is appreciable, the cost is low, weight is light, and can be moved away or demolished when it is unsuitable for equipment or the durability decreases, which is environmental protective and has little influence to the ocean environment.

Description

technical field [0001] The invention relates to a squid egg attachment reef with a net-like flexible structure. Background technique [0002] Squid, especially golden squid and Mansoni squid are important economic fish resources. They used to be one of the four major fisheries in my country. They had a high yield, rich nutrition and high economic value. However, the life cycle is short, and all sexual maturity is achieved at the age of 1, and the progenitors gradually die after delivery. Due to overfishing and environmental pollution, the amount of resources has decreased sharply, and fish floods have not formed, and squid resources have been severely damaged. Effective measures are urgently needed to restore its resources. Studies have found that the eggs laid by squid are adhesive eggs, which need to be attached to other attachments. The abundance of squid resources mainly depends on the amount of eggs laid and the survival rate. Therefore, it is necessary to provide an...
