PROBLEM TO BE SOLVED: To provide a floating fish bank body capable of suppressing reduction of buoyancy of a float.SOLUTION: A fish bank body 2 of a floating fish bank 1 gathers fishes in a floating state in the sea. The fish bank body includes: a hollow frame body 21; a float accommodation part 22 accommodated in the frame body 21; and floats 23. On an outer face of the frame body 21, an opening 31 is formed in a size permitting passage of a fish. The frame body 21 includes a space 26 communicating with the opening 31. The float accommodation part 22 is disposed in an inner part of the space 26 of the frame body 21. The float accommodation part 22 forms a migration space 36 in an outer part of the float accommodation part 22 by partitioning the space 26, the migration space allowing a fish to migrate therein, and the float accommodation part 22 includes a peripheral wall 33 forming an accommodation space 37 therein, the accommodation space separated from the migration space 36. The floats 23 are accommodated in an inner part of the accommodation space 37 of the float accommodation part 22.SELECTED DRAWING: Figure 4 |
