Oysters are bivalve molluscs in the family Osteridae of the order Ostereoida and are found throughout the world. Quality of stored muscle of oyster, <em>Crossostrea glomerata</em> depends on the temperature and storage time. Investigation on factors responsible for spoilage of oyster meat in refrigerator (7±2°C); in term of biochemical indices, indicated that in 1-2 days the following changes will accur: oyster tissue total protein from 7.6±0.44g% to 7.06±0.64g%, salt soluble protein from 3A6±0.52mg% to 2.53±0.14g%.Totallipid from 3.0±0.38g% to 2.5±0.29g%, TMA from 1.1±0.11 mg% to 1.46±0.09 and TVB, from 946±0.29mg% to 19.33±0.06 and on 7<sup>th</sup> day of storage, total protein to 4.5±0.32g%, salt soluble protein to 1.1±0.21g%, total lipid to 1.4±0.19g%, TMA, to 4.3±0.41 mg% and TVB to 83.3±3.5 changed. Amount of Glycogen in fresh meat was 5.3g% which decreased to 3.2g% during 7 days storage. Water content in fresh tissue was 79.0±0.57g% and increased at 7±2°C gradually with the increase of storage time. After 7 days it reached to the highly significant (p<0.001) value of 89.1±0.54g%.pH in fresh tissue was also noted 6.60±0.17and slightly non significant change was observed during 7 days of storage. On the 7<sup>th</sup> day it decreased to 6.3±0.05 from its fresh tissue value significantly (<em>p</em>£0.001) with storage time. Results concluded that oyster meat could be preserved for 4 days up to acceptable refrigeration temperature.
