The 'Pritchard Trap' is a novel survey method originally designed to survey crayfish. Here we tested whether the PT would also be suitable for benthic fish surveys. Surveys were carried out in a rocky headwater system in North Yorkshire, UK. A deployment time experiment was undertaken to determine the minimum deployment time. Data for deployment intervals of 1, 2, 4, 7 and 10 days are presented. The PTs were also compared to the Triple Drawdown (TDD) technique and electrofishing. Date from electrofishing surveys (2018), TDDs (2018) and repeat PT sampling (2019) are presented.
