Thanks. I guess I was thinking about looking to see if there is dna from upstream passing by. At some point I'd guess it is hard to tell if there are fish upstream but I'm not sure how to think about what factors are important. On the other hand just looking at streams isn't the worst thing to do. I don't think my own curiosity is a good enough reason to build a trap or barrier. But a camera is a good idea. I actually just picked up some parts from blue robotics to put together a setup for one or more cameras using some stuff I have laying around. Cool sticklebacks! One of the places I stumbled on Sculpins was in the Taylor River on Vancouver island. I saw something moving and nearly froze myself staying in until I found several of them.

Nice, I was very close to that area (maybe 50km over the woods and mountains to the east). There were tons of sculpins in that river, too. Such a beautiful area. I've never seen blue robotics before. I almost wish I hadn't, haha. This is going to soak up some time. Their low light USB camera looks awesome for stream monitoring. You could probably even get decent footage in the shady areas (where I find a lot of fish prefer to be). Maybe under some rocks on an overcast day with lots of diffused light? Could be awesome! Its peak draw is only 220mA so you could actually record a ton of footage on a raspberry pi 5 without a massive power source (10,000mAh should get you somewhere around 2.5 hours, I think?)
