For a landing net, I really like the one that I used in this video:

For smaller fish like cutthroat trout, I can keep that net submerged and let it swim around in it while I get the camera ready for photos or whatever. I got mine at Berry's but have seen them at other stores as well. I believe it is made by Gibbs but not totally sure.
Coastal cutthroat trout are pretty common in this part of the Fraser River during August, September and part of October if you are specifically targeting them. They are also by-caught while fishing for pink and coho salmon once awhile.
