PROBLEM TO BE SOLVED: To provide an oxygen generating agent package which is simple in structure, is easy to operate, is safe, is capable of generating oxygen stably for a long time and prevents the degradation in the activity of live fishes and the death thereof at the time of transporting by packaging a solid peroxide and a peroxide decomposing catalyst with a hygroscopic material which has specific cup method moisture permeability and does not allow the permeation of water under atm. pressure. SOLUTION: The solid peroxides, such as sodium carbonate hydrogen peroxide adduct, sodium perborate monohydrate and sodium perborate tetrahydrate and the peroxide decomposing catalysts, such as hydroxide, oxide, chloride, sulfate, acetate, carbonate and phosphate of various kinds of metals are packaged with the hygroscopic material which has the cup method moisture permeability (40 deg.C, 90% RH) of >=20 g/m<2> /24 hr, more preferably 20 to 100,000 g/m<2> /24 hr and does not allow the permeation of the water under atm. pressure in such a manner that the weight ratio thereof attains 100:0.01 to 100:100, by which the oxygen generating agent package is obtd. The live fishes are transported by encapsulating the oxygen generating agent package, the live fishery products and the water into a plastic transporting bag. |
