Working with Bull Trout
Having worked mainly with salmon the past 2 years I never really thought much about other fish species. Makes sense as salmon seem to be the primary focus on the west coast. But as of October of 2009 I became part of a new field crew called the Native Trout Crew. Within my first week with this new crew I found myself learning about a new fish species, the bull trout (Salvelinus confluentus). What I have learned so far is that Bull Trout are currently listed under the Endangered Species Act and that they tend to be found in colder water at higher elevations. Lucky for me this means a lot of cold weather, with temperatures as low as -11 °F at times. I can also tell you that Bull Trout prefer habitats such as pools, reservoirs, and lakes.
My favorite adventure thus far working with bull trout has been to the Eagle Caps in Eastern Oregon. Winter time looking for bull trout has proven to be quite an adventure. I actually had no idea fish biologists worked in the snow, but they do. Thanks to our friend max, our amphibious ATV, we are able to reach our PIT tag antenna sites at elevations of 6000 feet. So every month the native trout crew adventures out to Eastern Oregon to download data from our PIT tag antenna sites and make sure everything is operating correctly.
