Abstract

Quality characteristics of Rutilus kutum caught in twomethods, gillnet and beach seine during 16 days of ice storage by recording the microbial changes (psychrophil and total) were measured. Based on the results obtained microbiologcal indices were increased during storage and at first and last day of storage showed significant difference (P<0.05). Psychrophilic bacteria showed more uniform than the total bacteria and with time were dominant in the ice. The results of this study showed that overall fishing methods has significant effect on microbial parameters examined and the beach seine method have a less adverse effect on quality of fish in comparison with gillnet.
