ABSTRACT: To assess angling effort across Kentucky, time-lapse game cameras were purchased and installed at small urban impoundments. Cameras were set up to take a picture every half-hour from daylight to dusk. Only images at the top of the hour were used for analysis, however, the half hour pictures helped postulate if someone was fishing. These remote, fixed position cameras are able to monitor many lakes, capturing effort for a full 12-month period, while capturing daily and seasonal angling trends. Most cameras did not cover the entire bank access, in which case a correction factor was employed by conducting roughly 20 in-person instantaneous counts at the same time the picture was taken. This allowed for a regression model comparing the number of anglers actually fishing versus the number of anglers appearing on camera. Timelapse Image Analyzer software was used to assist staff with image analysis. Cameras were collected after the 12-month period and there were no instances of vandalism. This data will aid in assessing if current stocking strategies are adequate for the amount and timing of angling effort. The first year of the study included lakes that range in size from 1-14 acres. In subsequent years, a separate group of lakes will be surveyed including several larger lakes. Additionally, these cameras may prove beneficial in assessing angler usage at boat ramps and remote stream access points.
