LingcodKilla posted:Is that bottom a pike minnow? Yeah, Colorado Pikeminnow. No idea on stomach. Since they're endangered and my study doesn't currently have any focus on diet, we don't lavage them. Measure, weigh, scan for PIT tag, release.

LingcodKilla posted:I thought it was a pike minnow but didnt realize the Colorado sub species was in trouble. The broad mouth is kinda unique for a big CA fish. Where is your study out of? I've been a volunteer with Moss Landing research center for over 6 years. I work in the upper Colorado River basin. Utah and Colorado mainly. The Colorado, Green, Yampa, and White rivers mostly, plus their tribs. To partially answer your question, that particular fish probably had a red shiners, redside shiners, sand shiners, and white suckers in its gut. That's the primary forage base of the area right now.

LingcodKilla posted:Very cool. The big complaint with them in the Sacramento basin is they eat all the juvenile trout, salmon and stripers. Not even considered a game fish out here but they attain decent size. Yeah, it's kind of interesting that an imperiled ancient group of species like that (given that most ancient species are imperiled in their native range) can be super invasive and properly gently caress up another ecosystem that is geographically very close but still outside their native range. I think it's northern pikeminnow that are the big problem in the PNW. Burbot are in major decline in the upper Green River basin, where they are native, but are invasive in the middle Green.
