Know your fish
Ten species, and two of them get mixed up constantly. These are illustrations, not
photographs — drawn to show the features you actually use to tell them apart.
Chinook Salmon
King · Commonly 15–25 lb, over 30 lb in a good year
How to tell Black gums and a black mouth, and spots on both lobes of the tail. The gum line is the giveaway — a coho's is white.
Offshore June–August, staging off the river mouths August–September
Coho Salmon
Silver · 6–15 lb
How to tell White gums with a black tongue, and spots on the upper lobe of the tail only. Stockier and smaller than a king.
Building through summer, best August–October
Steelhead
Lake-run rainbow · 6–15 lb
How to tell Spotted all over, tail included, with a pink stripe down the side. Square-ish tail rather than deeply forked.
Tributaries November–April, peak March
Brown Trout
Nearshore · Commonly 5–12 lb, to 20 lb
How to tell Golden-brown with black and red spots, many ringed by a pale halo. Almost no spots on the tail.
Shallow on the west end April–June
Lake Trout
Deep water · 8–25 lb
How to tell The deepest tail fork of any trout here, and pale spots on a dark body — the reverse of everything else.
Bottom in 90–140 feet, May–August
Atlantic Salmon
Restoration fishery · 4–12 lb
How to tell Black spots shaped like Xs above the lateral line, and a notably slim wrist where the tail joins. Few spots on the tail itself.
Scattered, best May–July
Smallmouth Bass
Eastern basin · 2–5 lb, and plenty of them
How to tell Bronze with dark vertical bars and a red eye. The jaw stops below the eye, not behind it — that's what separates it from a largemouth.
June–September around shoals and islands
Walleye
Bays and rivers · 3–8 lb
How to tell A glassy, reflective eye and a white tip on the lower lobe of the tail. Two separate dorsal fins, and real teeth.
May–September, rivers and bays
Northern Pike
Weed edges · 4–15 lb
How to tell Duck-bill snout and pale bean-shaped spots on dark green. One dorsal fin, set a long way back.
Year-round in the bays, best spring and autumn
Yellow Perch
Schooling · Half a pound to a pound and a half
How to tell Golden with six to eight dark vertical bars and orange fins. Two dorsal fins.
Best in the bays November–March
Original illustrations. Diagnostic markings are
drawn deliberately — the Chinook/coho gum line and tail spotting, the lake trout fork,
the walleye tail tip.
