Voices from the River: Talking trash fish

Colorado pikeminnow: don't talk trash about natives (credit: U.S Fish and Wildlife)

Ugly fish. Trash fish. Suckers. Chubs.

A lot of native fish in our rivers don’t get no respect. Many anglers consider them good for nothing, except for throwing back—way back onto the bank.

But we anglers and sportsmen who care about rivers and cutthroats need to adjust our attitude a bit and quit looking down our noses at some of the “other” native fish.

Turns out “trash” fish like Colorado pikeminnow, razorback sucker, humpbacked chub, bonytail and other native species are critically important to river and trout habitat conservation efforts here in the Colorado River Basin and other watersheds in the West.

And trout and other angler-favored species are riding their fintails to a better life.

The pikeminnow has been around for millions of years in the Colorado Basin and can grow up to 6 feet long and live for decades. Pioneers used pitchforks at times, it’s said, to haul them out of the river, they were so abundant. The fish provided food (albeit a bit bony) for the settlers.

But with growing water diversions, drought, invasive species and other factors pressuring the river in the last half century, the numbers of these native fish plummeted, and they were listed under the Endangered Species Act. In 1988, the Upper Colorado River Endangered Fish Recovery Program was launched to bring them and the chubs and suckers back to sustainable numbers.

For three decades, the program has fostered cooperation, rather than conflict, among water users and directed federal and state funds to infrastructure projects that have benefited multiple users, from ranchers and farmers to municipalities.

Trout Unlimited and other conservation groups have supported those efforts, because the water projects, improved infrastructure and enhanced river flows needed to recover pikeminnows, suckers and chubs also benefit upstream coldwater species like trout.

For instance, TU helped upgrade the Relief Ditch and Hartland irrigation diversions on the Gunnison River a few years ago—a project that improved habitat and flows for trout.

The project would not have been possible without funds directly tied to native fish recovery.

Cary Denison, TU’s project coordinator in the Gunnison area, says that many anglers don’t realize that much of the West’s native trout have been removed from their historical ranges, and the remaining “natives” are those fish that many consider to be trash fish.

“If we aim to improve these rivers, we need to leverage the importance of these species to improve trout habitat as well.”

They are some of the original members of that river community, and they belong there. We need all of the pieces of a river ecosystem intact to keep it healthy.

So take a second look at that “trash” fish and give it some serious props for helping improve and restore our rivers for the other fish species we love.

The Ugly fish are part of the river's echosystem. They are necessary for a healthy stream. Think INTERDEPENDENCY!

I have caught many hard fighting whitefish while fishing for trout. Something is eating many of the little whitefish or they would overpopulate the stream. I think it is probably a lot less expensive to let trout eat whitefish than freshly planted hatchery (dumb) trout. I've caught quite a few large trout with large sculpin patterns. Trout must be eating them too. I've caught trout with many kinds of native fish hanging out of their mouths, too. Natural reproduction is "free" as long as the stream is healthy.

We definitely need more articles on this topic. The common assumption is that these fish compete with trout and the habitat would be healthier without them. Dam removals bring all sorts of different species together, that at one time existed together.  Catch and release of all native fish sounds like a plan.
