摘要: Abstract Identifying where fish inhabit is a fundamentally important topic in ecology and management allowing acoustically sensitive times areas to be prioritized. Passive acoustic localization has the benefit of being non-invasive non-destructive observational tool, provides unbiased data on position movement aquatic animals. This study used time difference arrivals (TDOA) sound recordings four-hydrophone array pinpoint location male oyster toadfish, Opsanus tau, cryptic that produces boatwhistles attract females. Coupling TDOA method with cross correlation different boatwhistles, individual toadfish were mapped during dawn (0523–0823), midday (1123–1423), dusk (1723–2023) night (2323−0223) examine relationship between temporal spatial trends. Seven males identified within 0.5–24.2 m hydrophone 0.0–18.2 m other individuals. Uncertainty passive acoustics was investigated using computer simulations as
