The storage stability of eviscerated Indian mackerel ( Rastrelliger kanagurta ) irradiated at a dose of 1.5 kGy and held under melting ice was examined. Packaging in polyethylene pouches prior to irradiation gave a shelf‐life of 25 days, while, nonpackaged, irradiated fish remained in acceptable condition up to 20 days. The nonpackaged irradiated fish has less irradiation odor and better appearance as compared with packaged irradiated fish during the course of ice storage. Uni‐radiated and nonpackaged mackerel kept in ice were acceptable only for 14 days. The results suggest that pre‐irradiation packaging was not essential for commercially adequate extension in shelf‐life of the iced fish.
