The milky fiddler crab (Austruca lactea) is a benthic macroinvertebrate that plays a crucial role in maintaining the functions of tidal flat ecosystems and is classified as an endangered species in Korea. In this study, we used an exponential saturation model to estimate the population density of A. lactea across different sites and to determine optimal survey durations. We established 15 quadrats measuring 1×1 m in the tidal flats of Shindo and 12 in Boryeong, recording cumulative detections over time. The estimated population densities were 6.95 individuals m-2 (95% CI: 4.42-10.54) in Boryeong and 10.00 individuals m-2 (95% CI: 6.56-15.24) in Shindo. The estimated survey times required to detect 99% of individuals present within the plots were 312.2 seconds in Boryeong and 548.7 seconds in Shindo. The exponential saturation model allows for quantitative correction of imperfect detectability, facilitating reliable estimation of population density even with limited survey time. This study offers a practical and reproducible methodological framework for monitoring populations of endangered species.
