Abstract Shelf life and quality of fresh fishery products can be extended by them under modified atmosphere in a high barrier film coupled with ice storage. Modified Atmospheric Packaging (MAP) studies were carried out using pearl spot (Etroplus suratensis). A gas mixture, which is recommended for most of the fishes having a definite composition of CO2 :O2 :N2 in the ratio 40:30:30 was employed. Whole pearl spot was subjected to MAP and air packing in see-through pouches of configuration of 12 polyester/300 gauge low density polyethylene and were kept at 0-2°C. Sampling was done regularly and modified atmospheric samples were compared with air packed samples. Chemical, microbiological and sensory parameters of the samples were studied. Chemical parameters such as TBA, FFA. TVN and AAN were found to increase during storage whereas changes in SSN were not significant indicating that there was no denaturation of proteins during storage. Chemical parameters studied were found to be in good correlation with the sensory scores. No incidence of pathogens was noticed during the storage period. It was found that MAP samples gave a shelf life of about 18 days whereas air packed samples gave a shelf life of only 11days.
