Pikeminnows, formerly squawfish, are cyprinid fish of the genus Ptychocheilus consisting of four species native to western North America. Voracious predators, they are considered an "undesirable" species in many waters, largely due to the species' perceived tendency to prey upon small trout and salmon. First known in western science by the common name Columbia River dace, the four species all became lumped under the name "squawfish". In 1999, the American Fisheries Society adopted "pikeminnow" as the name it recommends, because Native Americans consider "squawfish" offensive. [1]
The Colorado pikeminnow, P. lucius, is the largest member of the genus, ranging from 4–9 lb (2–4 kg) in adult fish with occasional specimens up to 25 lb (11 kg). Historical and anecdotal reports of Colorado pikeminnows nearing 6 feet (1.8 m) in length and 80 lb (36 kg) in weight have been made. The species is near extinction in its native Colorado River Basin habitat, due to extensive habitat destruction.
On the Columbia and Snake rivers from approximately May through September anglers are paid for each northern pikeminnow that they catch (from within program boundaries) that is 9 inches (23 cm) or larger in total length, and the more you catch, the higher the reward. Rewards begin at $5 each for the first 25 northern pikeminnow caught during the season. Anglers are paid $6 for each they catch from 26–200 fish, and $8 for every fish caught over 200 cumulatively. Anglers are also paid $500 for each specially tagged northern pikeminnow. [2]
The four recognized species are: [3]

The muskellunge, often shortened to muskie,musky, ski, or lunge, is a species of large freshwater predatory fish native to North America. It is the largest member of the pike family, Esocidae.
The largemouth bass is a carnivorous freshwater ray-finned fish in the Centrarchidae (sunfish) family, native to the eastern and central United States, southeastern Canada and northern Mexico. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largie, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, green trout, Gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth.
The northern pike is a species of carnivorous fish of the genus Esox (pikes). They are commonly found in moderately salty and fresh waters of the Northern Hemisphere. They are known simply as a pike in Great Britain, Ireland, most of Eastern Europe, Canada and the U.S., although in the Midwest, they may be called a Northern.
Esox is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family Esocidae. The type species of the genus is Esox lucius, the northern pike.
The northern red snapper is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the western Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico, where it inhabits environments associated with reefs. This species is commercially important and is also sought-after as a game fish.
The chum salmon, also known as dog salmon or keta salmon, is a species of anadromous salmonid fish from the genus Oncorhynchus native to the coastal rivers of the North Pacific and the Beringian Arctic, and is often marketed under the trade name silverbrite salmon in North America. The English name "chum salmon" comes from the Chinook Jargon term tsəm, meaning "spotted" or "marked"; while keta in the scientific name comes from Russian, which in turn comes from the Evenki language of Eastern Siberia. The term 'Dog Salmon' is most commonly used in Alaska and refers to the Salmon whose flesh Alaskans use to feed their dogs.
The Chinook salmon is the largest and most valuable species of Pacific salmon. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name chavycha (чавыча).
The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae native to Eastern North America in the United States and Canada. Two ecological forms of brook trout have been recognized by the US Forest Service. One ecological form is short-lived potamodromous populations in Lake Superior known as coaster trout or coasters. The second ecological form is the long-living predaceous anadromous populations which are found in northern lakes and coastal rivers from Long Island to Hudson Bay, which are referred to as salters. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook char, squaretail, brookie, or mud trout, among others. Adult coaster brook trout are capable of reaching sizes over 2 feet in length and weigh up to 6.8 kg (15 lb), whereas adult salters average between 6 and 15 inches in length and weigh between 0.5 and 2.3 kg. The brook trout is characterized by its distinctive olive-green body with yellow and blue-rimmed red spots, white and black edged orange fins, and dorsal vermiculation. The diet of the brook trout is restrictive to the season and location of the fish, but will typically consist of terrestrial and aquatic insects, fry, crustaceans, zooplankton, and worms.
The cutthroat trout is a group of four fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. These four species are the Coastal, Westslope, Lahontan, and the Rocky Mountain. As a member of the genus Oncorhynchus, it is in the Pacific trout group, which includes the widely distributed rainbow trout. Cutthroat trout are popular gamefish, especially among anglers who enjoy fly fishing. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw. The specific name clarkii was given to honor explorer William Clark, coleader of the Lewis and Clark Expedition.
Sea trout is the common name usually applied to anadromous (sea-run) forms of brown trout, and is often referred to as Salmo trutta morpha trutta. Other names for anadromous brown trout are bull trout, sewin (Wales), peel or peal, mort, finnock (Scotland), white trout (Ireland), Dollaghan and salmon trout (culinary).
Hippoglossus stenolepis, the Pacific halibut, is a species of righteye flounder. This very large species of flatfish is native to the North Pacific and is fished by commercial fisheries, sport fishers, and subsistence fishers.
The Northern pikeminnow, Columbia River dace or colloquially Squawfish is a large member of the minnow family, Leuciscidae. This predatory freshwater fish is native to northwestern North America, ranging from the Nass River basin to the Columbia River basin. A good deal of concern has been expressed regarding the impact northern pikeminnow populations may have on salmon in Columbia and Snake River impoundments.
Squawfish may refer to:
The Colorado pikeminnow is the largest cyprinid fish of North America and one of the largest in the world, with reports of individuals up to 6 ft (1.8 m) long and weighing over 100 pounds (45 kg). Native to the Colorado River Basin of the southwestern United States and adjacent Mexico, it was formerly an important food fish for both Native Americans and European settlers. Once abundant and widespread in the basin, its numbers have declined to the point where it has been extirpated from the Mexican part of its range and was listed as endangered in the US part in 1967, a fate shared by the three other large Colorado Basin endemic fish species: bonytail chub, humpback chub, and razorback sucker. The Colorado pikeminnow is currently listed as vulnerable by the IUCN, while its NatureServe conservation status is "critically imperiled".
Rough fish is a term used by some United States state agencies and anglers to describe fish that are less desirable to sport anglers within a defined region. The term usually refers to larger game fish species that are not commonly eaten, are too rare to be commonly encountered, or are not favorably sought by anglers for sporting purposes. Many of these species are actually very important in the commercial fishing industry, where they make up the bulk of commercial food fish catches in inland freshwater bodies.
The largescale sucker is a species of sucker, a type of freshwater fish, found in western North America.
Carp is a common name for various species of freshwater fish from the family Cyprinidae that are native to Eurasia and sought after by some recreational fishermen. Certain carp species have been introduced, with mixed results, to various other locations around the world, and even declared invasive in certain regions.
Porgy is the common name in Australia for any fish which belongs to the family Sparidae. They are also called bream. Porgies live in shallow temperate marine waters and are bottom-dwelling carnivores. Most species possess grinding, molar-like teeth. They are often good eating fish, particularly the gilt-head bream and the dentex.
The Sacramento pikeminnow, formerly known as the Sacramento squawfish, is a large cyprinid fish of California, United States. It is native to the Los Angeles River, Sacramento-San Joaquin, Pajaro-Salinas, Russian River, Clear Lake and upper Pit River river basins. It is predatory and reaches up to 1.4 m (4.6 ft) in total length.
The San Juan River Basin Recovery Implementation Program or (SJRIP) is a river management project that was established to recover two endangered fish species in the San Juan River, the Colorado pikeminnow (Ptychocheilus lucius) and the razorback sucker (Xyrauchen texanus), while allowing water development and management activities to continue in the San Juan River Basin.
