Monthly Catch Per Unit Effort (CPUE) of narrow-clawed crayfish (Pontastacus leptodactylus) for Baited Remote Underwater Video (BRUV), Remote Underwater Video (RUV) and trapping surveys. CPUE for BRUV and RUV is the sum of MaxN (maximum number of individuals in frame at a single moment in deployment) divided by the number of deployments for each survey. CPUE for trapping is the total number of crayfish caught divided by the number of traps deployed for each survey.
