National Electrofishing Programme for Scotland Fish Counts

Marine Scotland established a programme of research to develop a juvenile salmon assessment method that can be used to determine the status of salmon populations at a range of spatial scales. This dataset includes counts of salmon (the target species) and other fish caught by electrofishing as part of the National Electrofishing Programme for Scotland (NEPS). Counts are provided for each species and run (pass). Salmon and trout are further separated by lifestage (fry and parr). Site-visit information (site name, date fished and area fished) are also provided. The salmon counts contained in this dataset underpin Malcolm et al. (2019).

Important notes:

Data were exported from the relevant databases on 17-12-2018.

Comprehensive quality control of the data has currently only been completed for salmon.

Users should familarise themselves with the NEPS design, data collection and data entry protocols prior to using these data. These details are provided by Malcolm et al. (2019) alongside a comprehensive analysis of the salmon data.

Data Dictionary

This dataset includes counts of salmon (the target species) and other fish caught by electrofishing as part of the National Electrofishing Programme for Scotland (NEPS: https://www2.gov.scot/Topics/marine/Salmon-Trout-Coarse/Freshwater/Monit...). Counts are provided for each species and run (pass). Salmon and trout are further separated by lifestage (fry and parr). Site-visit information (site name, date fished and area fished) are also provided. Substantial quality control has been undertaken on the salmon dataset, with less quality control undertaken on trout, eels and other fish species which have not yet been analysed by MSS.

Raw data from NEPS were stored in both the Marine Scotland Science FishObs database and the Scottish Fisheries Coordination Centre database (SFCC). Substantial data manipulation has been undertaken to harmonise data exports to provide this DOI dataset to underpin further analysis. Users should look to Malcolm et al. (2019: particularly Appendix 2) for further details on data manipulation.
