Problems solved by technology

[0005] Prior art such as Chinese Invention Publication Document, Publication No. CN 104604762 A, a sinking cage longline culture method and its cultivation device in an open sea area, the device can cultivate snails or abalone in a sea area of ​​8-15 meters, and overcomes the The problem that the aquaculture space in the shallow sea area within 8 meters is too crowded, and the growth of abalone and snails is easily affected, but the area and aquaculture environment where the device is placed is not conducive to the growth of snails and abalone, and has little effect on the production increase of abalone and snails. Big

Embodiment 1

[0017] like figure 1 As shown, a sunken snail breeding device, a frame built by pipes 4, and nets 5 connected around the frame, an inflatable pipe 3 connected above the frame, pipes 4 at the bottom of the frame extend vertically downwards, and the inflated pipes 3 The upper end is provided with a valve 2, and the pipes 4 at the bottom of the frame are provided with inlet and outlet holes 6; the opening and closing of the valves 2 are used to control the opening and closing of the inlet and outlet holes 6 on the pipes 4 at the bottom of the frame, and the inside of the pipes 4 forming the frame The air intake has buoyancy or the water intake makes the aquaculture device sink or float in the water. The overall buoyancy of the device is greater than the gravity in the state of air intake in the pipe 4, and the overall gravity of the device is greater than the buoyancy in the state of water in the pipe 4, so that the device can be raised and lowered in the aquaculture water body S...

Embodiment 2

[0021] refer to figure 2 and image 3 , the optimization scheme of this embodiment on the basis of Embodiment 1 is: a kind of submerged snail class breeding device, a frame built by pipe material 4, and a netting 5 connected around the frame, with an inflatable tube 3 connected above the frame, The pipe material 4 at the bottom of the frame extends vertically downwards, the upper end of the inflation pipe 3 is provided with a valve 2, the pipe material 4 at the bottom of the frame is provided with an inlet and outlet hole 6, and a weight 9 is hung in the frame; block 9 to improve the sinking efficiency of the device, so that the 4 parts of the pipe extending vertically downward at the bottom of the device are inserted into the seabed mud to realize the fixing and supporting effect of the breeding device in water. With the increase of the weight of the cultured animals in the breeding device, it decreases. During the breeding process, the increased production of the cultured ...

Embodiment 3

[0024] refer to Figure 4 , the optimization scheme of present embodiment on the basis of embodiment 1 is: net clothing 5 is double-layer net clothing, and net clothing is made of netting wire, and the center of netting line is provided with cavity 4a at intervals, and cavity 4a is made of ethylene-vinyl acetate The copolymer layer 4b is sealed, and the ethylene-vinyl acetate copolymer layer 4b is surrounded by polyethylene wires 4c, and slow-release gel 4d is arranged between the polyethylene wires 4c, and the volume of the cavity 4a of the network cable accounts for 1 / 10 provides less buoyancy for the breeding device, reduces the inflation amount of the inflatable tube 3, is beneficial to energy saving, seals the cavity 4a through the ethylene-vinyl acetate copolymer layer 4b and improves the overall elasticity and flexibility of the network cable, and the poly The vinyl thread 4c is beneficial to enhance the strength and service life of the mesh cable, so that the designed...

Abstract

The invention discloses a sink snail culture and proliferation device, and belongs to the technical field of snail breeding. The breeding device comprises a frame constructed by pipes and a netting connected around the frame. An inflating pipe is connected on the frame. The pipes at the bottom of the frame extend downward vertically. The upper end of the inflating pipe is provided with a valve. The pipes at the bottom of the frame are provided with water inlet and outlet holes. A counterweight block is suspended in the frame. A control device is lifted and lowered in the aquaculture water so that the device arrangement is enabled to be completely fit with the natural growth environment of the snails. The suspended counterweight block can not only estimate the culture yield but also providea shelter for the snail seedlings. The sink snail culture and proliferation device has the advantages of simulating the natural growth environment of the snails, estimating the snail yield in the culture process, facilitating breeding of the snail seedlings and facilitating culture management and production planning.

Description

technical field [0001] The invention belongs to the technical field of snail breeding, in particular to a sunken snail breeding device. Background technique [0002] In marine development, islands and reefs are given priority, and fishery is given priority. Islands and reefs are the frontier and important fulcrum of my country's ocean development, and it is also an important area for fishery development. The intertidal zone along the southeast coast of my country mainly has three types of bottom: reef, mud and sand. The intertidal zone along the coast of the mainland is dominated by muddy bottom, followed by reef and sandy bottom. The length of the coastline in the middle zone is more than 60%, and the area accounts for more than 50%. There are dotted islands and reefs along the coast of Zhejiang and Fujian. For example, there are 13,395 islands in the Zhoushan Islands, and more than 3,500 longitudinal islands and reefs. The intertidal zone of the reef bottom is the main b...
