Meaning as a salmon river

The Grímsá is considered to be one of the best salmon rivers in Iceland, but over time, particularly large salmon have become rare. According to a report submitted to the Icelandic Marine Research Institute, 1,053 salmon were fished in Grímsá and 48 in the Tunguá tributary in 2018, of which 62.3% were released. The average weight of small salmon was 2.52 kg and that of large salmon 4.99 kg in 2018.

An average of 1318 salmon were fished in this river between 1974 and 2017. Since 2012, the results for Grímsá have fluctuated more strongly than for other salmon rivers in Iceland.
