Estimates of four metrics from a subset of acoustic telemetry detection data that included only acoustic receivers equipped with near-bottom dissolved oxygen (DO) data loggers. The metrics were estimated with a linear mixed model with dissolved oxygen category as the main effect and tag as a random effect. Hypoxia was defined as DO < 2.0 mg/L, and the difference between DO categories were also estimated. For B) and C), the data were further reduced to pairs of detections on different receivers (indicating movement), with the dissolved oxygen category was defined by initial conditions at the receiver.

Test/initial conditions	Hypoxic	Normoxic	Difference
(A) Difference between tag and receiver depth (m)	− 0.314 (− 0.99, 0.362)	1.697 (1.31, 2.09)	2.012 (1.442, 2.581)
(B) Change in tag depth (m)	0.256 (− 0.395, 0.552)	0.0001 (− 0.06, 0.06)	− 0.256 (− 0.553, 0.041)
(C) Change in dissolved oxygen (mg/L)	0.408 (0.204, 0.611)	− 0.068 (− 0.11, − 0.03)	− 0.476 (− 0.681, − 0.271)
(D) Proportion of days moved	0.748 (0.661, 0.835)	0.633 (0.588, 0.679)	− 0.115 (− 0.196, − 0.034)
