Effects of catching methods on quality changes of Rutilus kutum (Kamensky, 1901) during storage in ice

The quality of fish varies among the different methods of capture and storage times. In this study Rutilus kutum was captured by beach seine and gillnet and stored for up to 16 days; thereafter the changes in microbiological quality (total viable and psychrophilic counts) and chemical quality (pH, total volatile basic nitrogen, thiobarbituric acid, and free fatty acids) were evaluated. The storage time and method of capture had significant effects (P < 0.05) on bacteriological and chemical values. Depending on the time involved, the bacteriological counts and chemical values increased significantly (P < 0.05). Results indicate that the beach seine method has fewer adverse effects on fish quality compared to gillnet fishing, thus the present work recommends the beach seine method as preferable.
