Northern Pike
Pike and muskieEsox lucius · also called pike, jack, snake
Pike and muskellunge are separated by two features that are easy to check and worth getting right, because muskie limits are far more restrictive almost everywhere. Light spots on dark means pike; dark markings on light means muskie.
Quick facts
- Appearance
- Long, cylindrical and olive-green with rows of light bean-shaped spots on a darker background, a duck-billed snout and a mouthful of needle teeth.
- Typical size
- 2–20 lb
- Waters
- lake, river, reservoir
- Regulations
- Muskellunge typically carry much larger minimum sizes and lower limits than pike. If you cannot tell which you have, release it.
How to confirm it
- Light spots on a darker body — the reverse of a muskie's pattern.
- Cheek fully scaled, gill cover scaled only on the upper half.
- Five or fewer pores under each side of the lower jaw.
- Rounded tail lobes.
What it is confused with
One check settles each of these.
Pattern direction. Light spots on dark is pike; dark bars or spots on a light body is muskie. Count jaw pores too: pike five or fewer, muskie six or more.
Chain pickerel
Pickerel has a bold chain-link pattern and is much smaller, rarely over four pounds.
Why this matters beyond curiosity
- Look-alike species often carry different limits. Walleye and sauger, black and white crappie, pike and muskie, blue and channel catfish — each pair can have different sizes, seasons and daily limits in the same water.
- Check it before the fish goes in the livewell. Most of the tests on this site take seconds and are far easier on a fish you are still holding.
- If you cannot tell, release it. That is the answer that is never wrong, and it is the one a warden will not argue with.
- Regulations are set by your state or province and change annually. This site identifies fish; it does not tell you the rules. Check the current regulations for the water you are on.
