An Evaluation of the Success and Failure of Traps Designed for Exotic Sea Snail (Rapana venosa) Fishing Located on the South-Eastern Black Sea Coast

Abstract Research trials were carried out in the Samsun shelf region, where snail fishing is most common, in summer and autumn. The design of the net in the trap trials was inspired by the model used in South Korea. In the trials, the traps were kept in the sea for 24, 48, and 72 hours. According to the findings, an average of 0.31, 0.13, and 0.10 kg/day/basket were caught in the summer period, and an average of 0.15, 0.06, and 0.04 kg/day/basket in the fall for all three holding periods, respectively. In terms of catch per unit effort (CPUE) compared to the traditional beam trawler, economically satisfactory results could not be obtained.
