摘要

In the context of small-scale coastal fisheries, understanding the interaction between passive fishing gear and specific benthic habitats is essential for optimizing catch efficiency while ensuring ecological sustainability. This study utilized an observational approach involving repeated deployments of an innovative, unbaited fish trap across sandy, muddy, and rocky habitats at Batu Rakit Beach, Terengganu, Malaysia to evaluate gear performance under natural environmental conditions. The traps dimensions (1.6 m × 1.5 m × 1.5 m) utilized a 1.5-inch mesh and selective escape doors were deployed for 90 days, and checked every two days to access gear-habitat interactions. A total of 231 individuals across 25 species were recorded, with target species primarily Lutjanus johnii comprising 86.15% of the total catch. Significant differences (p < 0.05) were observed among habitats, which the sandy habitat yielded the highest number of individuals, whereas the muddy habitat produced larger fish sizes. The rocky habitat exhibited the highest species richness (6% of total species), likely due to greater habitat complexity. Positive correlations were identified between catch numbers and environmental variables, particularly salinity (r = 0.92) and sea surface temperature (r = 0.91), indicating that environmental conditions influenced fish distribution and trap efficiency. Overall, the findings demonstrate that this innovative trap enhances selectivity toward target species while maintaining low bycatch levels. The study underscores the importance of considering habitat characteristics and environmental conditions in managing passive fishing gear to support sustainable small-scale fisheries and conservation.
