Burlington Bottoms Wildlife Mitigation Site : Five-Year Habitat Management Plan, 2001-2005, 2000-2001 Progress Report.

Abstract

Each gear has a characteristic catchability range depending on species, size, and environment, that relates actual abundance or biomass density to catch-per-unit-effort (CPUE) with catch as numbers or weight of fish, respectively. A consistent protocol does not guarantee constant catchability, but makes it minimally variable in given habitats across floodplain units. Maintaining protocols will also permit the future application of catchabilities estimated from efficiency calibrations on-site, or with similar gear, species, and habitats elsewhere. This would transform CPUE data to actual abundance or biomass estimates. Where smaller water bodies exist, standardized protocols using backpack electrofisher or electric seine will be employed and maintained at those sites and seasons.
