Catch and water quality data for Invasive European green crab in Lummi River, Nooksack River and the Lummi Sea Pond in 2022

In this project, researchers at the Lummi Nation trapped for EGC and simultaneously gathered water quality data (e.g., temperature and salinity) from selected marine habitats on their reservation and along transects between estuarine areas of the Lummi and Nooksack rivers. The spatiotemporal data was analyzed along these gradients and compared with trapping data collected from Lummi’s 750-acre marine aquaculture pond (positive “control” for EGC presence) to assess what approaches maximize trapping efficiency of EGC in brackish and freshwater habitats. The spreadsheet dataset includes water quality and catch data for invasive European green crab trapping between April and September 2022 for Lummi River, the Nooksack River, and Lummi Sea Pond.
