Not AvailableChanges in the physical appearance, biochemical and microbiological quality of four marine fish viz., Sardinella albella, Pennahia anea , Pentaprion longimanus , Scomberoides lysan during iced storage was studied. The fish were procured in fresh condition from Visakhapatnam Fishing Harbour on the east coast of India. Major changes in physical appearance at the time of loss of microbiological quality during iced storage varied with the fish species. Scomberoides lysan showed blackening of gill cover, blackening at the origin of pectoral fin and the eye sclera turned to yellow; Sardinella albella showed reddish gill cover; Pentaprion longimanus lost its silvery white hue and scales; Pennahia anea showed skin rapture and gills turned pale red. The Aerobic Plate Count crossed 5,00,000 cfu per gram after 4 days, 6 days, 6 days and 21 days of iced storage of Pentaprion longimanus, Scomberoides lysan, Sardinella albella and Pennahia anea, respectively. The Total Volatile Base Nitrogen exceeded 35 mg per 100 gram after 2 days, 6 days, 8 days and 21 days of iced storage of Pentaprion longimanus, Sardinella albella, Scomberoides lysan and Pennahia anea.Not Availabl
