What Do Trout Eat?

Trout is one of the most popular fish angled in America. Coast to coast, there is a variety of species of this delicious, hard-fighting game fish, each with its unique characteristics and habitat preferences. 

However, most species share much of the same diet throughout North America. While some dietary differences are dictated by size and geography, for the most part, trout eat the same creatures across the United States.

This article covers what trout eat, some of the best baits to use when angling for trout, and answers a few more questions.

What do trout eat?

what do trout eat

Trout eat a variety of things. Opportunistic predators, they can be selective in certain circumstances but will oftentimes eat the gamut from insects to algae and, in some cases, cannibalize their own young. Much of their diet depends on their location and season, but there are a few constants throughout.


If you’ve ever caught a trout, felt the contents of its stomach, and found them to be hard as if the trout had consumed small rocks, you’re not far off. Trout will eat snails as a source of protein, digesting the creature itself but unable to consume or digest the shell for quite some time.


Many anglers will be surprised to discover that the waters of their favorite fishing hole are home to crawfish. A crustacean that ranges throughout the United States, crawfish are a staple in many trout diets.


The singular species of freshwater crab living in the United States, trout, have been noted to eat the Chinese mitten crab regularly if they share habitats. However, this crab is an invasive species and has been known to consume trout eggs as a source of protein.

Freshwater crabs, while not coming to the United States, can be an excellent food source for hungry trout.


Large trout have zero problems preying on mice and small mammals. Small rodents attempting to cross the streams, creeks, or rivers are often gobbled up in a Jaws-like fashion by hungry trout.

The largemouth bass usually takes the moniker of mammal and bird eaters; large trout will eat anything they can swallow shouldn’t be prey cross its waters.


Again, this occurs more often with largemouth bass, and brown trout have zero qualms about striking small birds or baby ducks crossing their waters. Opportunistic predators, trout will not distinguish a small duck from a rodent or frog making its way across a stream.


Trouts will eat small frogs and salamanders if they exist in the ecosystem. Similar to birds and rodents, these creatures will often attempt to cross waterways with trout lurking beneath and will be ambushed by the submerged predator.


Small lizards and snakes are not only commonly eaten by trout, but the former has been used to catch certain trout alongside smallmouth bass. Small lizards can be an effective lure as they commonly prey on hungry trout.

Minnows/ Small Fish

Small fish such as minnows, shad, and other fingerling or juvenile species commonly inhabit the shallows of many other waterways that trout hunt in. These small fish, in turn, become prey to hungry trout and can even be hooked beneath a cork to angle for these voracious aquatic predators.

Other Trout

Yes, trout are cannibals and commonly use their own young as a food source. Juvenile trout are in danger as much from their own species as they are from outside predators due to the voracious appetite of mature adult trout.


Trout will consume juvenile eels if they share the same waterway. However, this is a two edge sword as large eels have been observed to devour juvenile trout as well. 


Similar to crawfish, shrimp provide trout with an excellent source of nutrients. These protein-rich crustaceans often find themselves on a trout’s menu though much of this is seasonally dependent.


Trout will consume fish eggs, amphibian eggs, and insect eggs if the opportunity arises. These are easy sources of protein. When spawning season occurs for any of these creatures, trout will take advantage of the opportunity.


Trouts have been observed eating freshwater clams. Because trout lack the capability to crack open shells, they usually target juvenile shellfish, which can be swallowed whole.


Nightcrawlers, leeches, caterpillars, and blood worms find themselves on a trout dinner plate. Depending on the geography, species, and size of the trout, some of these worm-like organisms are staples like night crawlers and leeches. In contrast, others are seasonally dependent such as caterpillars.


Insects make up the vast majority of what trout eat on a daily basis. From small nymphs and larvae to dragonflies, a trout’s diet is largely made up of insects. 

Midges and flies that seasonally appear are some of the best fly fishing baits to use during the spring and summer months.
