However, this approach is becoming obsolete due to changes in communication technology such as a switch to unlisted mobile phones. Other methods, such as boat ramp interviews, are often impractical due to high labor cost. We trialed an autonomous, ultra\u2010high\u2010resolution photosampling method as a cost effect solution for direct measurements of a recreational fishery. Our sequential photosampling was batched processed using a novel software application to produce \u201cbig data\u201d time series movies from a spatial subset of the fishery, and we validated this with a regional bus\u2010route survey and interviews with participants at access points. We also compared labor costs between these two methods. Most trailer boat users were recreational fishers targeting tuna spp. Our camera system closely matched trends in temporal variation from the larger scale regional survey, but as the camera data were at much higher frequency, we could additionally describe strong, daily variability in effort. Peaks were normally associated with weekends, but consecutive weekend tuna fishing competitions led to an anomaly of high effort across the normal weekday lulls. By reducing field time and batch processing imagery, Monthly labor costs for the camera sampling were a quarter of the bus\u2010route survey; and individual camera samples cost 2.5% of bus route samples to obtain. Gigapixel panoramic camera observations of fishing were representative of the temporal variability of regional fishing effort and could be used to develop a cost\u2010efficient index. High\u2010frequency sampling had the added benefit of being more likely to detect abnormal patterns of use. Combinations of remote sensing and on\u2010site interviews may provide a solution to describing highly variable effort in recreational fisheries while also validating activity and catch.<\/jats:p>","DOI":"10.1002\/ece3.4301","type":"journal-article","created":{"date-parts":[[2018,8,29]],"date-time":"2018-08-29T21:02:17Z","timestamp":1535576537000},"page":"9372-9383","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Gigapixel big data movies provide cost\u2010effective seascape scale direct measurements of open\u2010access coastal human use such as recreational fisheries"],"prefix":"10.1002","volume":"8","author":[{"given":"David J.
