The technical scheme of the invention is as follows:
a fence trapping method based on feeding trapping comprises a separating device positioned in a fence for fence cultivation, wherein the separating device comprises a floating frame floating on the water surface, a separating cylinder device and a feeding pipe, the separating cylinder device comprises a separating net cylinder arranged on the floating frame, an isolating cylinder body positioned below the separating net cylinder, a floating isolating cylinder sleeved outside the isolating cylinder body, a limiting block arranged on the outer side surface of the isolating cylinder body and positioned below the floating isolating cylinder, an annular inflatable air bag sleeved outside the floating isolating cylinder, a connecting rope for connecting the annular inflatable air bag with the floating isolating cylinder and an inflating pipe, the upper end of the isolating cylinder body is open, the lower end of the isolating cylinder body is closed, the upper end of the isolating cylinder body is connected with the lower end opening of the separating net cylinder, the upper end of the inflating pipe is fixed on the floating frame, and the upper end of the inflating pipe is positioned above the water surface, the lower end of the charging pipe is communicated with the inner cavity of the annular charging air bag, the feeding pipe is positioned in the separation net cylinder, the upper end of the feeding pipe is positioned above the water surface, and the lower end of the feeding pipe extends downwards into the isolation cylinder;
the seine trapping method based on feeding trapping sequentially comprises the following steps:
firstly, continuously throwing baits or intermittently throwing baits into the separation net cylinder from the upper port of the separation net cylinder;
secondly, bait is thrown into the isolation cylinder body through the feeding pipe, and then the annular inflatable air bag is inflated through the inflation pipe to enable the annular inflatable air bag to inflate and expand, so that the floating isolation cylinder is driven to float;
thirdly, carrying out net casting and fishing in the purse nets for purse net culture.
Preferably, when the floating isolation cylinder abuts against the limiting block, the floating isolation cylinder is located below the separation net cylinder.
Preferably, the upper port of the separation net cylinder is positioned above the water surface, and the lower part of the separation net cylinder is positioned below the water surface.
The invention has the beneficial effects that: not only can protect the juvenile fish from being damaged by the fishing net in the fishing process, but also can effectively avoid the problem that the juvenile fish is fished.

Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, a seine trapping method based on feeding trapping comprises a separation device positioned in a seine 1 of seine breeding.
The separating device comprises a floating frame 2 floating on the water surface, a separating cylinder device arranged on the floating frame and a feeding pipe 3.
The separating cylinder device comprises a separating net cylinder 4 arranged on the floating frame, an isolating cylinder 5 positioned below the separating net cylinder, a floating isolating cylinder 6 sleeved outside the isolating cylinder, a limiting block 7 arranged on the outer side surface of the isolating cylinder and positioned below the floating isolating cylinder, an annular inflatable air bag 8 sleeved outside the floating isolating cylinder, a connecting rope for connecting the annular inflatable air bag and the floating isolating cylinder and an inflation pipe 9.
The upper port of the separation net cylinder is positioned above the water surface, and the lower part of the separation net cylinder is positioned below the water surface.
The upper end of the isolation cylinder body is open, and the lower end of the isolation cylinder body is closed. The upper end opening of the isolation cylinder body is connected with the lower end opening of the separation net cylinder.
The upper end of the inflation tube is fixed on the floating frame, and the upper end of the inflation tube is positioned above the water surface. The lower end of the inflation tube is communicated with the inner cavity of the annular inflatable air bag.
The feeding pipe is positioned in the separation net cylinder. The upper end of the feeding pipe is positioned above the water surface, and the lower end of the feeding pipe extends downwards into the isolation cylinder.
When the floating isolation cylinder is abutted to the limiting block, the floating isolation cylinder is positioned below the separation net cylinder.
The seine trapping method based on feeding trapping sequentially comprises the following steps:
firstly, bait is thrown into the separating net cylinder from the upper port of the separating net cylinder. The bait feeding mode is continuous bait feeding or intermittent bait feeding.
In the process of feeding baits, fishes in the purse net for purse net culture are gathered to the separation net cylinder, wherein juvenile fishes enter the separation net cylinder through meshes of the separation net cylinder, and adult fishes are blocked outside the separation net cylinder by the separation net cylinder.
Meanwhile, in the process of feeding the baits, the residual baits fall into the isolation cylinder body downwards, so that the baits are prevented from overflowing to influence the separation effect of the juvenile fishes and the adult fishes; and can lure some juvenile fish low reaches in the separation net section of thick bamboo to the isolation cylinder body to make the juvenile fish quantity in the separation net section of thick bamboo keep at certain volume, avoid the juvenile fish in the separation net section of thick bamboo intensive, and influence external juvenile fish and get into the separation net section of thick bamboo, lead to the juvenile fish in the separation net section of thick bamboo to swim out even, and influence the problem of the separation effect of juvenile fish and adult fish.
And secondly, bait is thrown into the isolation cylinder body through the feeding pipe, and when the bait is thrown into the isolation cylinder body through the feeding pipe, the bait is stopped to be thrown into the separation net cylinder body from the upper port of the separation net cylinder body.
Then, the annular inflatable air bag is inflated through the inflation tube, so that the annular inflatable air bag is inflated and expanded, and the floating isolation cylinder is driven to float upwards.
When bait is thrown into the isolation cylinder body through the feeding pipe, juvenile fishes in the separation net cylinder are attracted into the isolation cylinder body, and then the annular inflatable air bag is inflated through the inflatable pipe to drive the floating isolation cylinder to float, so that the problem that the separation effect of the juvenile fishes and adult fishes is influenced because the juvenile fishes in the separation net cylinder swim out due to the floating interference of the floating isolation cylinder can be avoided.
After the floating isolation cylinder floats upwards, the separation net cylinder is sleeved, so that the separation net cylinder is separated from the external water area, and further juvenile fishes and adult fishes in the purse net for purse net culture are separated.
Thirdly, carrying out net casting and fishing in the purse nets for purse net culture.
Because the juvenile fish distributes in the separating cylinder device, not only can protect the juvenile fish not receive the fishing net damage at the in-process of catching that spills the net like this, can effectively avoid the problem that the juvenile fish was caught moreover.
