    • Abernathy Fish Technology Center scientist at work

    • Fish hatcheries; Fisheries management; Fishes; Employees (USFWS); Work of the Service; Uniforms; Service patch;
    • Fish Biologist Richard Glenn from the Abernathy Fish Technology Center studies fish DNA with the help of a PCR machine. This device is used to amplify copies of DNA samples to assist the scientists in identifying genetic variations in fish...
    • Aquatic Insect

    • Fish hatcheries; Fisheries management; Fishes; Biologists (USFWS); Employees (USFWS); Work of the Service; Tagging; Threatened species; Monitoring;
    • Biologists find other aquatic creatures while tagging steelhead in Eagle Creek. Biologists use this tracking information to see if the hatchery fish that are spawning here are affecting the survival and productivity of the wild fish.
    • Baited trap used to capture nutria

    • Aquatic animals; Invasive species; Mammals; Rodents; Wildlife management; Trapping; Tagging;
    • A trap baited with carrots and apples awaits a nutria to venture out of the water and investigate. The animals are trapped in order to tag them to better understand the habits of nutria and to prevent their spreading.
    • Bucket of Rinsed Eggs

    • Fishes; Fisheries management; Fish hatcheries;
    • A bucket of rinsed eggs at the Carson National Fish Hatchery.
    • Caged Nutria

    • Aquatic animals; Invasive species; Mammals; Rodents; Wildlife management; Trapping; Tagging;
    • A caged nutria, waiting to be tagged. The animals are trapped in order to tag them to better understand the habits of nutria and preventing their spreading.
    • Caged Nutria is Covered to Keep Animal Calm During Tagging

    • Aquatic animals; Invasive species; Mammals; Rodents; Wildlife management; Trapping; Tagging;
    • A sheet covers the caged nutria to keep it calm during the tail tagging. Tagging the animals will help biologists to better understand the nutria and prevent their spreading.
    • Carson National Fish Hatchery

    • Fish hatcheries; Fisheries management; Fishes;
    • Image of Carson National Fish Hatchery where eggs are rinsed and then stored.
    • Chinook Salmon Waiting To Be Spawned

    • Fish hatcheries; Fisheries management; Fishes; Work of the Service;
    • The Chinook salmon are held here after making their way up the elevator into the spawning room.
    • Cleaning Equipment

    • Fish hatcheries; Fisheries management; Fishes; Employees (USFWS); Biologists (USFWS); Work of the Service; uniforms; service patch;
    • Everything is cleaned with an iodine solution and water after each use.
    • Collar Tag for Nutria

    • Aquatic animals; Invasive species; Mammals; Rodents; Wildlife management; Trapping; Tagging;
    • A collar tag to be put on a nutria. It's designed stretch so it can be put on snugly and a nutria will neither get a limb stuck inside nor have trouble breathing. Tagging the animals will help biologists to better understand the nutria's habits and...
    • Damage Caused by Nutria

    • Invasive species; Interpretation; Photography; Mammals; Rodents; Work of the Service; Wildlife management;
    • Damage caused by nutria digging into the banks at Tualatin National Wildlife Refuge. USFWS and Pangolin Film's are joined in an effort to create awareness surrounding the dangers of the spreading non-native nutria populations in the northwest...
    • Eagle Creek

    • Fish hatcheries; Fisheries management; Fishes; Biologists (USFWS); Employees (USFWS); Work of the Service; Tagging; Threatened species; Monitoring; Rivers and streams;
    • Biologists tag steelhead in Eagle Creek. Biologists use this tracking information to see if the hatchery fish that are spawning here are affecting the survival and productivity of the wild fish.
    • Egg Storage

    • Fish hatcheries; Fisheries management; Fishes;
    • After getting rinsed the eggs are placed in storage containers at the Carson National Fish Hatchery.
    • Electroshocking for Steelhead in Eagle Creek

    • Fish hatcheries; Fisheries management; Fishes; Biologists (USFWS); Employees (USFWS); Work of the Service; Tagging; Threatened species; Monitoring;
    • Electroshocking is a non-lethal process that creates involuntary muscular responses in fish and causes them to float towards the surface of the water.
    • Female Chinook Being Spawned

    • Fish hatcheries; Fisheries management; Fishes; Employees (USFWS); Biologists (USFWS); Work of the Service;
    • The eggs are removed from the females and placed in a container. Each female Chinook has between 4,000-5,000 eggs.
