Title-style description of the project? format: < 70 words in 'paper title' form Characterisation of fish movement and spatial use patterns in Saint John Harbour 2. Brief abstract of the project? format: < 500 words in 'abstract' form The Port of Saint John (New Brunswick, Canada) is a major industrial harbour that hosts a large amount of vessel traffic (e.g., fishing, cruise, and container ships) as well as extensive oil and gas facilities. While economically beneficial, these activities contribute to the risk of marine pollution events, especially with respect to hydrocarbon spills (e.g. diesel, gasoline, crude oil). Marine pollution events in the area are particularly worrisome given that the surrounding waters host a highly diverse and productive ecosystem supporting a large number of ecological, cultural, and economic services to southwestern New Brunswick and beyond. Further complicating matters is that Saint John is in close proximity (~20 km) to the Musquash Marine Protected Area, which could be adversely impacted by nearby spills under the certain tide/current conditions. Together, this has prompted federal agencies to proactively develop response plans to mitigate potential impacts that a hydrocarbon spill could have on the marine environment. As these spill response plans are evidence based, primary research and data inputs are needed to be able to develop regionally-relevant and data-driven toolsets. However, the understanding of the spatial ecology of aquatic organisms in the Saint John Harbour area is lacking, which precludes the ability to develop effective spill response plans for the region. The purpose of this study was to characterise biodiversity patterns (i.e. presence/absence) as well as understand the spatial ecology of aquatic organisms in Saint John Harbour as primary data inputs into marine spill response planning efforts. In addressing this, an acoustic array consisting of nine acoustic receivers (VR2AR, 69 kHz, InnovaSea; 45.230019,-66.037788) was deployed adjacent to the navigational channel at the mouth of the approach to Saint John Harbour, effectively creating a large gated receiver array. Several species of fish, selected for their cultural and economic importance to the area, will be tagged in Spring 2025 and will be monitored for their use of the harbour. Tagged species will include Atlantic salmon, Atlantic mackerel, winter flounder, and tomcod. This project will also monitor for animals tagged outside of our research group, that will be used to help inform both local biodiversity indices and spatial use patterns in the harbour. Together, these data will help to develop data-driven spill response toolsets allowing for more effective and informed reactions to marine pollution events by management agencies. 3.
