We combined a high-resolution acoustic telemetry array with presence/absence receivers to conduct a preliminary study of the seasonal movements, activity patterns, and habitat associations of the newly described Deacon Rockfish (Sebastes diaconus). Eleven mature female Deacon Rockfish were tagged and monitored during an 11-month period, at a nearshore rocky reef off Seal Rock, Oregon, USA, an area of recurring seasonal hypoxia (defined as dissolved oxygen concentration [DO] < 2 mg l⁻¹). Two tags were detected leaving the study area by day 35, indicating predation or emigration. Three tags became inactive within the array, indicating tag loss or fish death. Six “resident” fish inhabited the array for 246–326 days. Resident fish exhibited high site fidelity, small home ranges (mean 95% KDE = 4907 m²), and consistent activity patterns for the duration of the summertime high-resolution array (5 months), except during seasonal hypoxia. Resident fish were strongly diurnal in summer, with high levels of daytime activity above the bottom in relatively rugose habitat, followed by nighttime rest periods in deeper, less rugose habitat. During summertime hypoxia, resident fish exhibited less daytime activity during daytime hours with no rest periods at night, inhabited shallower water depths, and moved well away from their core activity areas on long, erratic forays. During the winter, diel patterns were less evident with higher activity levels at night (than in the summer) and lower activity levels in the day (than in the summer). We propose that some Deacon Rockfish continuously inhabit nearshore reefs throughout the year, but that daily/seasonal movement patterns, seasonally occurring hypoxia, and prey preferences for planktonic organisms influence relocation.

我们将高分辨率声学遥测阵列与在场/不在场接收器相结合，对新近描述的执事岩鱼（Sebastes diaconus）的季节性运动，活动模式和栖息地关联进行了初步研究。在11个月的时间内，在美国俄勒冈州希勒洛克（Seal Rock）附近的近岸岩石礁上，对11只成年雌性执事岩鱼进行了标记和监测，该区域反复出现季节性缺氧（定义为溶解氧浓度[DO] <2 mg l ^-1）。在第35天，发现有两个标签离开研究区域，表明它们被捕食或移出。三个标签在阵列中变为非活动状态，表明标签丢失或鱼类死亡。6条“常驻”鱼在该阵列中栖息了246-326天。驻地鱼类表现出较高的现场保真度，较小的家境范围（平均95％KDE = 4907 m ²），以及夏季高分辨率阵列（5个月）期间的一致活动模式，但季节性缺氧期间除外。夏季，常驻鱼类的昼夜活动强烈，相对较皱的栖息地的日间活动水平较高，高于底部，随后在较深，较不稀疏的栖息地进行夜间休息。在夏季缺氧情况下，常驻鱼类在白天时段白天活动较少，晚上无休息时间，居住在较浅的水深中，并且在漫长而不稳定的进水中远离其核心活动区域。在冬季，夜间活动水平高于夏季（白天），白天活动水平低于（夏季），迪尔模式不那么明显。我们建议一些迪肯礁石鱼全年持续栖息在近岸礁石中，
