Quality of tiger-toothed croaker stored in flake ice was studied for 19 days by sensory, chemical (total volatile basic nitrogen (TVB-N)), (thiobarbituric values (TBA)), pH and microbial (total viable count, TVC) methods. Sensory scheme was modified according to the panelists perception and a specific schema was created for this fish. Sensory analyses showed that: "gills color and odor", "convexity of eyes", "peritoneum" and "elasticity of flesh" are the best sensory parameters. Results of sensory and microbial analyses had high correlation. Total viable count of flesh was 2.86 log cfu g-1 at first day and reached the limiting level of TVC (106) after 15 days of storage (P
