Conventionally, in the work of lifting this type of fishing net for aquaculture, the bottom net and the entire net were raised above the sea surface by winding up the net rope from above the sea surface using a work boat. In addition, as a device that uses air to raise the entire bottom of a fish pen or box net, there is a sequential levitation type box net device having a structure in which air tubes are attached to two opposite sides of the bottom of the cage net, as disclosed in Japanese Patent Application Laid-Open No. 59-162828. In the publication, a floating/sinking type fish cage for aquaculture with a float tank attached to the bottom of the cage that can inject and discharge air was put into production in 1972.
It is known from Publication No. 161396.

This conventional net-lifting work has the problem of requiring a large number of people and time. Also, JP-A-59-162828
In the sequential floating type box net device described in the publication, there are only air tubes on two opposing sides, so it may not be possible to secure sufficient buoyancy, and the center part of the bottom of the net may sink more than the surrounding area where the air tubes are located. There are cases where it becomes difficult to collect fish etc. because of the crowding. Especially in the case of shellfish and seaweed, they sink and become difficult to collect. Another problem is that sequential levitation based only on the position of one long air tube lacks reliability. In addition, the floating/sinking/mobile aquaculture fish cage of Jitsukai No. 51-161396 is one in which the entire fish cage floats and cannot be recovered sequentially on the sea surface, making it difficult to recover at sea and in locations where recovery is easy, such as ports. There is a problem in that it has to be moved up to The present invention solves these problems and allows even one person to carry out the net-lifting operation.In addition, the bottom of the net can be raised sequentially from a predetermined point, and the fish in the net can be moved to one side to make it easier to catch.
The purpose is to provide a submerged net with a new concept that allows easy harvesting of seaweed, shellfish, etc.

The gist of the present invention is to generate sufficient buoyancy at required points on the net surface 1 in submerged nets such as fish cages and quantitative nets that are used by submerging a wide net surface approximately horizontally under the water surface. Three or more rows of expandable air tubes 2 are installed, and air outlet ports 3 are installed at both ends of the air tubes.
3' is also provided with another air outlet 3'' in its center, and the air outlets 3 and 3' at both ends of the air tube 2 are connected to the air outlet 3'' at the center of the different air tubes 2, thereby allowing multiple air inlets to be connected. The submerged net is characterized in that either one of the outlets 3, 3' or the air outlet 3'' is connected via an air hose 4 to an air inlet fitting 6 provided on a floating part 5 above the sea surface.

In the present invention, when used as a submerged net, the air injection fitting 6 is left open. Then, air is discharged from the air tube 2 by its own contraction force and water pressure, and the air becomes compressed.If the air injection fitting 6 is closed in this state, the net surface is 1 can be held approximately horizontally in seawater and can be used as a fish cage, fixed net, aquaculture net, etc. Next, when unloading the net, if the ship injects high-pressure air from the air inlet fitting 6 of the floating section 5 on the sea, the air tubes 2 will expand according to the order of connection, generating buoyancy and raising the net surface 1. The device is raised sequentially from a predetermined point, allowing fish, seaweed, shellfish, etc. to be easily harvested from ships at sea.

The embodiment shown in Figures 1 and 2 is an example applied to a rectangular parallelepiped-shaped fish cage, and a total of three air tubes 2 are attached to the two long sides of the mesh surface 1 on the bottom of the fish cage and the middle thereof, and the air tubes are Air tube 2 from right to left
The air is introduced sequentially into the air tube 2, and is injected from both ends of the air tube 2, exhausted from the center, and introduced into the other air tube 2 on the left side from both ends. FIG. 2 shows the connection state of the air tube. In this case, it is possible to raise the net surface 1 while driving the fish in the fish tank to the left.
It becomes easier to catch fish from ships at sea. In the figure, 7 is a float, 8 is an anchor rope, and 9 is an anchor.

As described above, according to the present invention, the surface of the net can be raised by injecting air at a single point on the ship, so not only can a single worker quickly and easily unload the net, but also the air tube comrades Depending on the connection order, the net surface can be floated from the required part in the required order, which has the effect of making it easier to harvest and inspect fish, seaweed, shellfish, etc. In addition, air tubes are installed on the bottom in three or more rows,
Moreover, since the air outlet at both ends and the air outlet at the center are alternately connected to each other, there is an effect that it is possible to reliably float a part of the bottom surface one after another without sinking.
