Monitoring of the Atlantic salmon stocks of the Teno (Tana) and Näätämö (Neidenelva) river systems, northernmost Fennoscandia.

Updated 2013-01-26

Monitoring of the salmon stocksof the Teno and Näätämö river systems is based on long term data collection on juvenile salmon production, biological characteristics of the spawning stock, origin of salmon (wild/reared) and statistics on fishery and catches. Information on other fish species than salmon is also available.

This is not a National Implementation Plan (NIP) project

Data availability

Are data archived or planned to be archived at an AMAP Thematic Data Centre?
no
If no (or only part of data are reported to a TDC), where and how are (other) data stored?
The data is at the FGFRI in an organized electronic data format (e.g. ASCII). Data is mostly available on request.
