    streamer

    Orange Flash Streamer

    #4#6#8

    Explicitly effective for various salmon species, this attractor streamer can also provoke strikes from Sheefish looking for an easy meal in the cold water.

    streamer

    Hot Pink Bunny Leech

    #14#16

    This flashy streamer effectively imitates both leeches and baitfish, and the vibrant pink color is a proven attractor for aggressive salmon and other predatory species in Alaska's clear, cold waters.

    streamer

    Clouser Minnow (Chartreuse/White)

    #4#6#8

    An excellent baitfish imitation, this weighted streamer will sink quickly and effectively mimic the primary forage that Sheefish and Northern Pike are actively seeking.

    streamer

    Egg Sucking Leech

    Leech/egg combination
    #2#4#6

    With salmon spawning activity having recently peaked, eggs will still be present and drifting in the system. This pattern combines a classic leech profile with an irresistible egg attractor, appealing to a wide range of predatory and opportunistic feeders.

    streamer

    Pine Squirrel Leech (Black/Olive)

    #14#16

    A smaller, yet equally effective, leech pattern that excels in cold water. Its natural movement in the current mimics sluggish annelids and small baitfish, making it an appealing meal for Sheefish, Pike, and even larger Grayling.

    egg

    Glo Bug

    Salmon/trout egg
    #8#10#12#14

    A classic egg pattern, vital for enticing opportunistic feeders like Arctic Grayling and Sheefish who will be actively scavenging on the protein-rich salmon eggs.

    nymph

    Zebra Midge (Black)

    #20#22#24

    For the more discerning Arctic Grayling, midges are a primary and consistent food source year-round. This weighted nymph is perfect for fishing deep in slower currents and will appeal to grayling holding in the deeper pockets.
