The Directorate of Nature Management (DN) forwards data to NASCO (North Atlantic Salmon Conservation Organization).
The statistics cover a time series from 1876 and are vital elements in national and international monitoring and management work related to anadromous salmonoids.
Catch statistics are an important source of information for nature management, the media and various organizations and groups. Scientists use the statistics to evaluate changes in stocks and to estimate the socio-economic importance of salmon fishing.
Norway is also obligated to report annual catch statistics to NASCO (North Atlantic Salmon Conservation Organization).
The statistics include catches of salmon, sea trout and migratory char taken by fishing rod in rivers. As from 2009 data on river catch and release are available.
Catch reports from the individual fisherman.
Not relevant.
Catch reports from the individual fisherman are collected by landowners, who send a summary catch report to the County Governor. The County Governor add up the figures for each river and send them to Statistics Norway. As from 2004 landowners and county governors may transfer data electronically by Internet.
Data is transferred to electronic format (Dynarev) and computerized controls are applied. If necessary, the county governors are contacted to assess the data.

Anadromous: Term referring to animals that regularly migrate from the ocean up the rivers to spawn.
Weight: The weight is stated in kilos live weight.
Before 1993 salmon were broken down into two groups: salmon under 3 kilos and salmon 3 kilos or more. Since 1993 salmon are divided into the following groups: under 3 kilos, between 3 and 6.9 kilos and 7 kilos and over.
Missing or delayed catch reports from fishermen and landowners can be a problem for the river catch statistics. Statistics are also lacking from some small river systems where fishing is poorly organized. Consequently, the statistics are not totally complete.
In 2009 data on river catch and release are collected for the first time, and the quality of the data may be uncertain.

The collection of data was reorganized in 1993. Previously, fishery boards collected data and sent reports from each salmon district and river to Statistics Norway. In 1993, the county governors started submitting reports.
Figures on sea catches of salmon and sea trout are presented on the Internet.
Figures are published in Today's Statistics and in StatBank.
Statistics Norway stores the data files. Register data and catch data are in Oracle tables. Final data files are stored on UNIX.
