Northern Pikeminnow (Ptychocheilus Oregonensis) Fish Description

Northern Pikeminnows are slender in appearance with silver bodies. They have gold-green backs with a single dorsal fin. Appearance-wise, some people have mistaken the Northern Pikeminnow for the Plymouth. In Asian countries, it’s possible that the Northern Pikeminnow might even be passed off as a Milkfish due to their similarities.

However, there are some clear-cut differences. The first difference is the barbels. Northern Pikeminnows have dark bars near their chins that serve as their barbels. Peamouths don’t have barbels and neither do Milkfish. Another is the way their mouths are designed. A Northern Pikeminnow’s mouth usually extends all the way to their eye. The edge of their mouth is parallel to the middle of their eye whereas a Peamouth’s mouth barely reaches its eye and that their lips are somewhat red. Milkfish is also differentiated from Northern Pinkminnows for their dark-colored backs (usually a navy-blue color).

However, Northern Pikeminnows also consume insects (some terrestrial and aquatic ones) and some plants.

Northern Pikeminnows can grow up to 2.1ft (25 inches) and can weigh as heavy as 7.5 lbs.
