The question of what fish are in the Delaware River is one that echoes from the quiet headwaters in the Catskills down to the bustling bay. It’s a query whispered by seasoned anglers prepping their gear and by families enjoying a day out on their pontoon. The river is far more than just a body of water; it’s a living, breathing ecosystem, a dynamic highway for an incredible diversity of aquatic life. Understanding this biodiversity is key to truly appreciating your time on the water, whether you’re casting a line or simply cruising. The legendary American shad run is a spectacle of nature, while the powerful striped bass provides a world-class challenge. Further upstream, the feisty smallmouth bass and elusive trout command respect, and in the deeper, slower sections, formidable catfish lurk. This river tells a story through its seasons and its species, offering a unique experience around every bend.
The Delaware River is not a single, uniform environment. It transforms dramatically over its 330-mile journey, creating distinct habitats that support a vast array of fish. The cool, clear, and highly oxygenated upper sections are a haven for cold-water species, while the warmer, wider, and more tidal lower sections host an entirely different community. This ecological variety is what makes the river a premier destination for boating and angling enthusiasts. To truly know the Delaware is to understand its seasonal rhythms and the fish that define them.
For those interested in exploring the unique challenges of its upper reaches, a deeper understanding of fly fishing the west branch of the delaware river offers a fantastic starting point for mastering one of the river’s most prized fisheries.
The Seasonal Stars: Migratory Fish of the Delaware
The heartbeat of the Delaware River can often be felt through its incredible migratory fish runs. These are the species that travel from the saltwater of the Atlantic Ocean deep into the freshwater reaches of the river to spawn, creating an annual spectacle that draws anglers and nature lovers from all over. These migrations are a critical part of the river’s ecological health, providing a vital food source for other wildlife and signaling the changing of the seasons.
The Legendary American Shad Run
When people talk about fishing on the Delaware, the conversation almost inevitably turns to the American shad. Dubbed the “Poor Man’s Salmon,” this species undertakes a heroic journey each spring, returning from the ocean to the very waters where they were born. This event transforms the river into a frenzy of activity. Boaters find themselves in the middle of a silver rush as thousands of these hard-fighting fish push upstream. Their arrival is a celebrated tradition, a true rite of spring for the communities along the riverbanks. For a focused look into this specific pursuit, diving into the techniques for shad fishing on the delaware river can vastly improve your chances of success during this exciting, but often brief, window of opportunity.
Chasing the Mighty Striped Bass
Following closely on the heels of the shad are the striped bass, or “stripers.” These powerful predators enter the river to spawn, with some specimens reaching truly impressive sizes. Catching a large, river-run striped bass is a pinnacle achievement for many anglers. They are known for their aggressive strikes and powerful runs, testing the limits of even the heaviest tackle. The pursuit of stripers often happens under the cover of darkness or during the crepuscular hours of dawn and dusk, adding a layer of mystique to the challenge. Anglers in the lower, tidal sections of the river eagerly await their arrival each year.
As riverine ecologist Dr. Eleanor Vance puts it, “The annual shad and striper migrations are the river’s lifeblood. They are not just fishing events; they are massive ecological transfers of marine nutrients into the freshwater system, fueling the entire food web for months to come.”
Year-Round Residents: What Fish Are in the Delaware River’s Freshwater Reaches?
While the migratory species get much of the fanfare, the Delaware River is home to a robust population of resident fish that provide excellent opportunities for boaters and anglers throughout the year. These are the species that define the character of the river’s non-tidal sections, from the rocky rapids of the Upper Delaware to the slower, deeper pools of the middle river.
The Feisty Smallmouth and Largemouth Bass
In the world of freshwater fishing, bass are king, and the Delaware River is prime territory. Smallmouth bass, in particular, thrive in the river’s clear, rocky habitats. Known for their bronze coloring and aggressive, acrobatic fights, “smallies” are a favorite target for anglers using everything from canoes and kayaks to larger fishing boats. They often congregate around submerged boulders, ledges, and current breaks. While less common than their smallmouth cousins in the main river, largemouth bass can be found in the slower-moving backwaters, coves, and tributaries where vegetation is more abundant.
Trout in the Tributaries and Upper Reaches
The upper main stem of the Delaware and its two primary branches, the East and West Branch, are hallowed ground for trout anglers. This area is considered one of the finest wild trout fisheries in the entire country. The cold, clean water flowing from the reservoirs in the Catskill Mountains creates a perfect environment for brown and rainbow trout to flourish. Fly fishing is the name of the game here, with anglers meticulously matching their fly patterns to the aquatic insect hatches that occur throughout the spring and summer. It’s a technical and rewarding form of fishing that requires a deep connection with the river’s rhythms.
Whiskerfish Wonders: Channel and Flathead Catfish
In the deeper, slower-moving sections of the river, a different kind of predator reigns. Channel and flathead catfish are the undisputed heavyweights of the Delaware’s resident fish population. These bottom-dwellers can grow to formidable sizes, with flatheads in particular being capable of exceeding 50 pounds. Anglers often target them at night from anchored boats, using heavy tackle and specialized baits. Catching a trophy catfish from the Delaware is a testament to an angler’s patience and strength, offering a completely different but equally thrilling experience to chasing bass or trout.
“The health of the smallmouth bass population is a direct indicator of the river’s overall water quality,” notes Dr. Vance. “When you see healthy, thriving bass year after year, it tells us that the habitat is stable and the food web is intact. They are the river’s sentinels.”
Unsung Heroes and Other Noteworthy Species
Beyond the big names, the Delaware is teeming with a variety of other fish that contribute to its rich tapestry. Walleye, with their large, milky eyes adapted for low-light conditions, are a prized catch, known for their delicious white flesh. Muskellunge, the “fish of ten thousand casts,” are the river’s apex predator—elusive, powerful, and a true trophy for any angler lucky enough to land one. Adding to this mix are abundant populations of panfish like crappie, sunfish, and yellow perch, which provide fantastic action for young or novice anglers and are a crucial part of the food chain.
| Fish Species | Primary Habitat | Preferred Diet | Best Season to Target |
|---|---|---|---|
| American Shad | Main river channel, migrating | Plankton, small crustaceans | Spring (April-June) |
| Smallmouth Bass | Rocky areas, current breaks | Crayfish, minnows, insects | Summer, Fall |
| Brown Trout | Cold, clear upper river/tributaries | Aquatic insects, smaller fish | Spring, Summer |
| Channel Catfish | Deep pools, slower currents | Baitfish, invertebrates | Summer (especially at night) |

An absolutely world-class fishery. I spend about 40 days a year on the Upper Delaware chasing wild brown trout, and it never disappoints. The insect hatches are incredible, and the scenery is second to none. It’s a challenging river that rewards skill and patience. Respect the resource, practice catch and release, and you’ll be hooked for life.

My family and I love taking our pontoon boat out on the middle section of the river near the Water Gap. While we aren’t serious anglers, the kids have a blast catching sunfish and small bass right off the side of the boat. It’s clean, scenic, and a perfect way to spend a summer afternoon. The boat traffic can get a little heavy on holiday weekends, but it’s manageable.

If you want to feel a real pull, you have to be here for the spring striper run. Launching before dawn and heading downriver towards the bay is an experience like no other. There’s nothing that compares to the thrill of a 30-pound striped bass hitting your lure in the dark. The Delaware is a special place for serious anglers.

We rented kayaks and paddled a section near Narrowsburg, NY. The water was so clear you could see the smallmouth bass darting around the rocks below. We weren’t fishing, but just seeing the amount of life in the river was amazing. A truly beautiful and well-preserved natural area. I’d recommend it to anyone who loves the outdoors.

I’ve been fishing for channel catfish on the lower Delaware for over 20 years. People get so focused on the trout and bass they forget about the giants living in the deep holes. It’s a different kind of fishing—quiet, patient, and often done at night. But the rewards are huge. The river has some monsters if you know where to look.
