Som key numbers from 2017

With a season well behind us, it’s time to present some key numbers from this year’s season.

We use the same calculations each year, and in that way we may be able to spot some long-term relationship between the numbers. Many of these numbers is the ground work for how we predict the season, but luckily nature is unpredictable, and we don’t always find that our predictions are correct.

The first chart shows the number of 1 SW, 2 SW and 3 or more SW fish are in our catches. Last year’s number of 2 SW fish was very low, which one should think lead to a decrease in 3 SW fish this year. As the chart clearly shows, this was one of the predictions that did not come through, since we had a record high percentage of 3 SW winter fish (or bigger) in 2017.


*Green: +3 SW fish, red: 2 SW fish, blue: 1 SW fish.


*Green: +3 SW fish, red: 2 SW fish, blue: 1 SW fish.

Even though the high average weight has a lot to do with a small number of grilse being caught this year, there is no getting away from the fact that 2017 was a good year for the “big ones”. An average weight of 11 kilos for +3 SW fish, and a total average of 7,4 kilos is quite remarkable.

Looking into the catches in a 10 year perspectiv, we had a small decline in 2017. Measuring in weight, it was only approximately 150 kilos (2 %). However, in numbers, the decrease was about 250 individuals (17 %). Looking at the stability we see in the next chart, we should be careful to contribute this to something other than natural variation. If these trends continue for several years, then it’s time to be worried.


Columns represent catches in kilos, and the read line catches in numbers. Note that the catch reports from before 2007 are quite unreliable, since catch reporting was far worse than what it is now.

In other news, ice is starting to cover the lakes around Lakselv, and the weather forecast for today is the first winterstorm. We will hold on tight, and are looking forward to a winter with lots of snow.

Talk soon!
