We specialize in using electronic fish counters to enumerate migrating fish in rivers and physical structures such as fishways and dams. We are the sole North American distributor of Aquantic resistivity counters and have operated resistivity counters throughout British Columbia since the late 1990s. Our fabrication team designs and builds counter infrastructure for custom applications. We design our counters to maximize efficiency and perform extensive post-season validation to provide uncertainty in abundance estimates.
We also use imaging sonar (e.g., BlueView, ARIS) to enumerate salmon and Steelhead Trout in diverse river environments. Our analysts are highly experienced using software programs that semi-automate fish counting to process sonar data and calculate species-specific abundance estimates. By combining resistivity counters and imaging sonar, we are able to obtain comprehensive population estimates in challenging applications.
