River Surveys 2020
River Barrow Catchment
Factsheet: 2020/1
This report summarises the results of a catchmentwide electrofishing survey undertaken in selected River Barrow sub-catchments during 2020. A total of 91 sites were surveyed by electrofishing (CEN, 2003) across the catchment in summer 2020. Surveys were carried out using 10-minute, timed electro-fishing (TEF10), with results converted to first pass Area Delineated Electro Fishing (ADEF) according to Matson et al. (2018). Fish ecological status is also reported for each site for Water Framework Directive purposes.
Corrib Catchment
Factsheet: 2020/2
A total of fifty-two sites were surveyed to assess the status of their fish stocks in the Corrib Catchment from the 22nd of July to the 16th of September 2020. This work complements the survey carried out during 2019 (109 sites surveyed in the Carra, Mask and Clare catchments – O’ Briain, 2020a and b). These surveys provide a comprehensive overview of fish status across the Corrib catchment.
Electro-fishing was the method used (CEN 2003), specifically the 10-minute timed electro-fishing (TEF) technique. All fish count results were converted to Area Delineated Electro Fishing (ADEF) according to Matson et al. (2018).
This report summarises the results of the fish stock survey in selected sub-catchments of the Lough Corrib Catchment in 2020. Fish ecological status is also reported for each site for Water Framework Directive purposes.
River Nore catchment
Factsheet: 2020/03
Forty-two sites were surveyed in the River Nore catchment by electro-fishing (CEN 2003) from the 7th of July to 30th of September 2020. The survey method used was 10-minute timed electro-fishing (TEF). All fish count results were converted to Area Delineated Electro Fishing (ADEF) according to Matson et al. (2018).
This report summarises the results of a catchment wide survey in selected sub-catchments of the River Nore Catchment in 2020. Fish ecological status is reported for each site.
