1. Rock Bass
   Northern Pike
2. Rainbow Trout
   Walleye

This predatory fish will aggressively go after smaller fish, a fact that makes the northern pike a favorite of fishermen since that means they're more than eager to go after bait. If you're catching one to eat, make sure you clean it well since they have a layer of mucus coating their scales.

1. Pumpkinseed
   Pickerel
2. Largemouth Bass
   Salmon

2. Common Carp
   Catfish

Largemouth bass may have large mouths but the rest of the fish isn't particularly big. A 5 lb bass is generally considered to be a healthy size but the world record is over 22 lb. Since bass never stop growing, you can tell you have an older fish if it's a big one.

1. Bluegill
   Ruffe

At least one British supermarket chain banned the sale of monkfish because of those concerns.

1. Atlantic Cod
   Dover Sole

1. Hake
   Brook Lamprey
2. Warmouth
   Silver Carp

The warmouth bass is often confused with the rock bass since the two look very similar and they are often called by the same nicknames like "Red Eye." The key to telling them apart is to check those fin spines because the warmouth will only have three while the rock bass has six.

1. Northern Pike
   Catfish
2. Lake Trout
   Smelt

Despite their small size, smelt are very popular for eating because of how you can fish them up. They often move together in groups of potentially millions, so during a smelt run when the fish come inland to spawn, many people will scoop up hundreds of them at a time and have a cookout right there.

1. Haddock
   Grass Carp

1. Dolly Varden
   Burbot
2. White Sturgeon
   Northern Pike

The name Dolly Varden comes from a book by Charles Dickens. How did it become a fish? There's a popular story that some anglers had caught the fish in the 1870s and were wishing it had a better name. This inspired a teenage girl who overheard to suggest Dolly Varden, after a brightly dressed character in the book she was reading at the time.
