We determine the presence or absence of fish species and estimate the size of natural populations through tailored monitoring programs designed for site-specific conditions.

Our experts track fish movement, develop periodicity charts for key life stages, and monitor population changes that may result from development activities.

We apply a wide range of proven methods – including electrofishing, snorkel surveys, minnow trapping, video surveillance, mark-and-recapture studies, and radio telemetry – to ensure accurate and defensible data collection.

Where traditional methods are limited, we employ environmental DNA (eDNA) sampling to detect elusive species or low-density populations, offering a cost-effective and precise solution for presence/absence studies.

Using technologies such as PIT tags with remote antenna receivers, we monitor fish migration patterns to inform habitat connectivity assessments and mitigation planning.
