Meet the Native Fish of the Malheur

Yes, we really like bull trout (like the one above), but we want to give a shout-out to all the native fish species swimming around in the Malheur Subbasin. Many of the fish below were captured during this year's surveys  by regional biologists. They were measured, weighed, and then given a tiny high five before being released safely back into their habitat.

 With a large set of 'sucker' lips at the bottom of their face, these fish eat algae and invertebrates off the bottom of the stream. The two different species are hard to tell apart...even for fish biologists! The best way is to look at differences in the sucker's lips. If you see a fish scientist up close and personal with a sucker fish...it's probably not for a fishy kiss. Instead, the scientist is using the lip structure to determine a bridgelip from a largscale. 
The Latin Names for these Fun, Friendly Fish: 
​Bridgelip: Catostomus columbianus
Largescale: Catostomus macrocheilus

Sculpin

Sculpin stick to the bottom of the stream (they don’t have a swim bladder). The Malheur Subbasin is home to two species of sculpin. These small native fish are camouflaged to match the surrounding gravel. They hide in swift water and ambush unsuspecting invertebrates for their dinner. Sculpin are indicators of a healthy ecosystem and play an important role in the food chain. Many anglers know this because a sculpin lure will capture the attention of the desired larger game fish!
The Latin Names for these Fresh, Funky Fish:
Mottled Sculpin: Cottus bairdi
Shorthead Sculpin: Cottus confusus

redband trout

A Species of Concern
Redband are a subspecies of rainbow trout and are an important native trout in Eastern Oregon. These trout are uniquely adapted to the warmer and more arid streams of Eastern Oregon. Key identification characteristics include: small black spots from tip of nose to tail and a red band down their side. The smaller fish in the photo is a dace (see below)

The Latin name for this Feisty, Funky Fish: Oncorhynchus mykiss spp

​Chiselmouth
​

​This member of the minnow family matches the name- they have a mouth which acts like a chisel. These fish use the hard plate on their bottom jaw to scrape tasty algae off of rocks- making them an important herbivore in freshwater food webs. Chiselmouth are found in lakes or larger rivers with their preferred neighbors, the northern pikeminnow and redside shiners. 

Then Latin Name for this Funky, Fresh Fish: Acrocheilus alutaceus

​

Northern PikeMinnow

As adults, northern pikeminnow are important freshwater predators...even though they do not have any teeth! Though their names are similar, the northern pikeminnow is an important native fish in the Malheur and other Oregon Rivers, but the Northern PIKE is an aggressive, invasive fish that was introduced to the Northwest.

The Latin Name for this Flippy, Fun Fish: Ptychocheilus oregonensis

Look at that adipose fin! This fish is in the same family as trout and char. Their unique mouth and shiny scales are a good trick to tell them apart. Whitefish can grow to be pretty big (over two feet) and some have been found to live almost 20 years.  Sadly, this native fish has been called a ‘trash fish’ by anglers…and they are nothing of the sort! Whitefish are important to the ecosystem and appreciated by those out flyfishing. These fish eat invertebrates in the lower water column (you will often find larger groups swimming on the stream bottom). Underwater, whitefish are so shiny, it's fun to think of them as ‘swimming disco balls.’ 


The Latin Name for this Funky, Friendly Fish: Prosopium willamsoni

Dace

Specked and Longnose dace are both found in the Malheur. Dace will eat both algae and small invertebrates- making them freshwater omnivores. These mighty minnows are neighbors with and often eaten by native trout species-. In this picture a dace and a redband were both scooped up in net during a stream survey which provides evidence for  a healthy stream ecosystem.

The Latin Name for these Flamboyant Fish: 
Longnose: Rhinichthys cataractae
Speckled: Rhinichthys osculus

Redside shiner

Redside shiners are small minnows  often found in slower moving or still waters (lakes and slow streams). Redside shiners show off their bright, colorful 'red sides' when they are ready to spawn. These fish are an important component in the freshwater food web- feeding larger fish species. As one biologist puts it, "Redsides are the bread and butter for bull trout." 


The Latin Name for this Funky, Football-shaped Fish: Richardsonius balteatus 

Historical Native Fish of The Malheur Subbasin

The Malheur Subbasin once sustained runs of anadromous fish. 'Anadromous' describes fish with lifecycles in which they were born in freshwater-migrate to the ocean to grow- then come back to their home streams to lay eggs! See the BPT summary page to get updates on work the tribe is doing to celebrate the cultural significance of Chinook Salmon.
