Brown Trout

Wild Brown Trout

While brown trout and brook trout have much in common, they also have their fair share of differences. So make sure to check for all these factors when trying to tell one from another.


Of the two, brown trout are larger than brook trout, usually measuring between 8 and 24 inches in length. But, of course, since they can each vary in size, it’s not the best way to make an identification. Luckily, several other visual indicators can help a conscientious angler tell them apart.

The brown trout has a much lighter color than the brook trout, with colors that include brown, orange, and copper with brown spots. The underbelly is more of a yellow or gold color, which is paler than the bellies of brook trout.

One other surefire way to visually distinguish brown trout is to look at their tails. The tail area should be similar to the underbelly, which is yellow or gold with little to no spots anywhere on the fin.

Brown trout aren’t always easy for anglers to find because they love to hide. While the waters they call home are usually clear, they tend to stay in areas with plenty of cover. Places where debris like rocks and overhanging vegetation have collected and deep pools are some of their favorite haunts. They are more likely to be found in colder streams and rivers, though they can live in places with different temperatures.

While their love of shady, secluded spots might make them seem like shy fish, the truth is that they can put up quite a fight once they’re hooked. Even experienced anglers can have a hard time netting one of these.

Taste and Texture

If you’ve had steelhead or rainbow trout before, you might have an idea of what brown trout tastes like. However, the difference is that these have a much stronger fishy flavor, putting some people off. That is especially true of the larger specimens, as their flavor intensifies with age.

While some people enjoy the fishy flavor, many prefer milder-tasting fish. Luckily, there is a trick that can help cut down on the overpowering taste. Simply soak the fish in milk overnight, and then prepare as usual.

The texture of brown trout can be described as firm, delicate, and flakey when cooked. In addition, it has a relatively larger grain, especially for full-sized fish.

Brook trout are, on average, a bit smaller than brown trout, staying between 6 and 15 inches in length. And so, a full-grown brook trout is only about as large as a relatively young brown trout.

The markings on the sides of the brook trout are much darker. The skin is a dark green that verges on black with bright pink spots surrounded by blue halos. This pattern changes as it reaches the back of the fish, looking more like worm-shaped squiggles that run from the head to the tail.

The belly of the fish, on the other hand, is nearly white, with two bands of bright orange running on either side of it. These colors will deepen and intensify as they reach the spawning season in fall.


You may think you can only find brook trout in smaller streams, but the truth is that they are much more versatile than that. You can find them in wide rivers, lakes and ponds, and even the ocean. One of the other characteristics that can differentiate them from brown trout is that they can live in muddier water.

While it seems that brook trout can live just about anywhere, one thing they must have is a suitable current. That is because they don’t chase their prey like some other fish. Instead, they wait for a meal to swim by.

Because of this, they are only rarely found in slow-moving water. At the same time, currents that are too strong can make it difficult for them to hold steady. Thus, they are happier swimming in medium-speed currents.

Taste and Texture

If brown trout are too fishy for you, you may find that you prefer the flavor of brook trout. These are much sweeter and milder, without any of the strong fishy flavors of other species. That means people can enjoy them in different ways, ranging from pan-fried to baked and to braised.

In terms of texture, they are light and flakey when adequately prepared. In addition, because they are smaller than brown trout on average, their flesh has a slightly finer grain.
