Fishing experiments were executed with in 6 stations by using traps and skin diving. In the study, 19 diving operations were performed by 2 divers with a mean duration of 36: 03 ± 0,002 minutes/dive. In totally 18 traps (3 traps in per stations) were used in 12 fishing trails. The traps soak times were 48 hours for each operation. As a result of fishing experiments, a total of 654 individuals belonging to 3 species and a total of 13 individuals belonging to 6 species were collected with skin diving and traps, respectively. In the experiments, a total of 598 E. verrucosa individuals, 596 of which were caught by skin diving and 2 were caught by traps as a target species. The CPUE for diving (CPUED = 14,32±3,12 individual, hours-1) were higher than the mean CPUE for traps (CPUES =0,0601 ±0,0186 individual, hours-1).
