PROBLEM TO BE SOLVED: To obtain a package of an oxygen generating agent having simple structure, enabling easy and safe operation, stably generating oxygen over a long period and effective for preventing the lowering of activity or the death of living fish during transportation by packaging a solid peroxide, etc., with a specific moisture-permeable material. SOLUTION: This package can be produced by packaging a solid peroxide consisting of one or more materials selected from adduct of sodium carbonate and hydrogen peroxide, sodium perborate monohydrate and sodium perborate tetrahydrate and activated carbon having a median particle diameter of 25-5,000μm with a moisture-permeable material such as a microporous membrane made of a plastic sheet having a cup moisture permeability (40 deg.C, 90% RH) of >=20 g/m<2> /24 hr and free from the penetration of water under normal pressure. The weight ratio of the solid peroxide to the activated carbon is 100/(0.01-100) and the packaged oxygen-generation agent is preferably sealed in a vessel for the transportation of live fish. |
