Are The Kenai River Kings Getting Smaller?

If you’ve been fishing the Kenai river for any length of time, you might have noticed that chinook run just isn’t what it used to be. I frequently hear from people who have been fishing the Kenai for decades complaining that the fish are smaller, and the numbers are shrinking too.

I won’t delve into the possible causes; believe me, everyone you talk to will have a strong opinion on whose fault it is. What I will do is look at trends in the chinook fishery over time to see in what ways it has been changing.

In the following paper, I take the data from the ADF&G’s netting project at river mile 8.5, and arrange it from 2012 to 2018 to look at age, sex, and length data as well as aspects of the run timing.

The statistics and methods are a little heady, however the graphs are easy enough to understand, and paint most of the picture.
