Panfish: Which Fish Count and How to Tell Them Apart

Panfish is an angler’s word, not a biologist’s: any small freshwater fish that fits a frying pan, which in practice means the sunfish (bluegill, redear, pumpkinseed and their kin), the two crappies, the yellow perch and, in the Northeast, the white perch. The one place the word has a legal definition is Wisconsin, whose bag-limit table counts bluegill, pumpkinseed, yellow perch and crappie as panfish and nothing else. Vermont’s list runs bluegill, pumpkinseed, redbreast sunfish, rock bass and crappie, “small, brightly colored sunfish” that “rarely exceed 10 inches”. Read on and you will be able to name the fish in your hand by its ear flap, know when it is a trophy rather than a keeper, know how many you may keep and how often you should eat them, and find the page for each species.

The heaviest panfish on the record books is not a bluegill. It is a 6 lb 4 oz redear sunfish from Lake Havasu, Arizona, caught in 2021, the third world record that lake has produced since quagga mussels arrived in 2007 and handed its redear an all-you-can-eat buffet.

Start here

• Bluegill: the fish most anglers catch first, the one-pound rule, and why the big males on the beds are the ones to release.
• Yellow perch: the fish-fry fish of the Great Lakes, whether it really is a bottom feeder, and why a jumbo is nearly always a female.
• White perch: a small striped bass relative, not a perch, that invaded the Great Lakes through the canals.
• Bluegill spawn temperature: the 67–80 °F (19–27 °C) window and how to find the beds.
• Crappie spawn temperature: the 55–68 °F (13–20 °C) window that starts the panfish year.

What counts as a panfish: three families

Most panfish are sunfish. The sunfish family, Centrarchidae, has eight genera and takes in the black bass and the crappies as well as the fish people mean when they say “sunfish”: the genus Lepomis, thirteen species that all share three spines in the anal fin, spiny and soft dorsal fins joined into one, and the flap on the gill cover that anglers call the ear. Every bluegill is a sunfish; not every sunfish is a bluegill. Rock bass is a sunfish too, but from the genus Ambloplites, and the one count that separates it from the warmouth it is confused with is six anal spines against the warmouth’s three.

Crappie are the two species of Pomoxis, also sunfish. Black crappie carry 7 or 8 dorsal spines, white crappie 5 or 6, and that count beats color every time, because breeding males of both species turn dark. Crappie get their own pages under the coming crappie hub.

The perches are the outsiders. Yellow perch is a true perch, Perca flavescens, the small cousin of the walleye and sauger in the family Percidae; the other two Perca live in Europe and Central Asia, so every other American “perch” is borrowing the name. White perch is Morone americana, a temperate bass in the striped bass family and, as the IGFA puts it, “not a true perch”. You tell it from a white bass by what it lacks: no horizontal stripes, and dorsal fins joined by a deep notch rather than separated.

Then there are the names. In the South “bream” or “brim” means any Lepomis, and “perch” almost always means a sunfish rather than a Perca. Texas Parks and Wildlife lists the bluegill as bream, brim, perch, sunfish and sunperch; the redear as shellcracker, Georgia bream, cherry gill and sun perch, with chinquapin added in Louisiana; the warmouth as goggle-eye, stump knocker and, confusingly, “rock bass”; the green sunfish as goggle-eye, rock bass and branch perch. Black crappie are specks in Florida, calico bass in the Northeast, sac-a-lait in Louisiana. When a stranger at the ramp tells you what he caught, ask what it looked like.

Types of sunfish: the ear flap settles it

Three marks sort nine sunfish in the hand. First, the color on the margin of the ear flap: none on a bluegill, red or orange on a redear, a red half-moon on a pumpkinseed, white on a longear. Second, the pectoral fin: long and pointed on bluegill, redear and pumpkinseed, short and rounded on green sunfish, longear and warmouth. Third, the mouth: a bluegill’s jaw stops short of the eye, a green sunfish’s or warmouth’s reaches the middle of it. Every row below comes from the state agency named in the second table.

The sunfish cross freely where they nest together, green sunfish most of all, and a fish with marks from two rows is not a mistake in the table. Wild hybrids stay a small share of any population; the hybrid bluegill sold to pond owners is bred on purpose, grows faster than either parent and, because nearly every one is male, has to be restocked when the catch rate drops.

How big is big: the one-pound bluegill

A bluegill in Iowa reaches 1–2 in (2.5–5 cm) in its first year, 3.5 in (9 cm) in the second, 4.5 in (11 cm) in the third and 6 in (15 cm) in the fourth; most bluegill caught are under 8 in (20 cm). In the Nebraska sandhill lakes an 8-in fish is 4 to 8 years old, depending on the lake. That is why a pound is a real trophy. On the standard-weight curve fisheries biologists use, a bluegill in average condition weighs 0.42 lb (190 g) at 8 in, 0.62 lb (280 g) at 9 in, 0.88 lb (400 g) at 10 in and 1.21 lb (550 g) at 11 in. A pound needs a fat 10-incher or any 11-incher, and Michigan’s Master Angler program sets its bluegill minimum at exactly 10 in (25 cm), with 9 in (23 cm) for pumpkinseed, green sunfish and warmouth and 10 in for redear and hybrids.

Redear grow bigger and die sooner: Texas biologists give them 12 in (30 cm) and 2 lb (0.9 kg) but “few individuals survive more than six summers”. Rock bass reach 11 in (28 cm) and a pound. And the record fish are fat rather than long. T. S. Hudson’s world-record bluegill measured only 15 in (38 cm) but weighed 141 percent of a standard fish that length; Thomas Farchione’s record redear was 17 in (43 cm) at 159 percent.

The records, all eleven panfish in one place

The all-tackle records from the IGFA list, the redear confirmed by the IGFA’s own July 2021 release and the yellow perch by its record page:

Three of these carry a story. The bluegill record came from two flooded limestone quarry pits north of Birmingham, private and closed to fishing, where sheer banks left the fish little spawning habitat and heavy bass predation kept them few, old and enormous; Hudson caught his on unweighted red worms from a cane pole. The yellow perch record is the oldest standing freshwater record in North America, 160 years and counting. And the white perch record was, for more than twenty years, a 4 lb 12 oz mount in the Maine State Museum that a suspicious curator finally had examined: white perch in front, largemouth bass behind. The record passed to lighter, honest fish, and now stands at 3 lb 8 oz from a Massachusetts reservoir.

When they spawn

The panfish year opens with the perch. Yellow perch drape their egg ribbons over weeds, brush and fallen trees at 44–52 °F (7–11 °C), shortly after ice-out, with no nest and no guard. Rock bass nest alone rather than in colonies at 54–59 °F (12–15 °C), timed with the smallmouth. Crappie follow at 55–68 °F (13–20 °C), black before white. The sunfish come last: bluegill males dig their saucers in colonies of fifty or more once the water passes 70 °F (21 °C), a Wisconsin study found no spawning below that figure and little above 80 °F (27 °C), and a lake’s colonies spawn in four to eleven bouts a season, two to three weeks apart, because a male needs about ten days to hatch a brood and a few more to recover. Redear bed deeper than the rest, usually beyond 3 ft (0.9 m). The two temperature pages under “Start here” give the month-by-region tables.

Bait, hooks and staying out of sight

Worms win everywhere. The Wisconsin DNR calls plain garden worms “the favorite bait”, and the redear’s diet of snails and mussels means it wants earthworms and grubs and “rarely approach[es] the surface to take flies”, in the words of Texas Parks and Wildlife. Hook sizes from the agencies run small: a No. 10 from North Carolina, a long-shank No. 8 from Iowa, size 10 to 14 for pumpkinseed from Oregon, all fished under a bobber. Bluegill feed by sight and feed most at dawn and dusk. Crappie anglers split between minnows and jigs of 1/32–1/8 oz (1–3.5 g) on 4–6 lb line, and perch anglers on Lake Erie hold shiners near the bottom on a spreader rig with a 3/4–1 oz (21–28 g) sinker, because a perch bite is a “soft tap”. North Carolina’s rule for a slow bank: no bluegill in fifteen minutes, move.

Can the fish see you on the bank? Yes, and better than most anglers think. A fish looking up sees the whole sky and shoreline squeezed into a cone about 97 degrees wide, so a person standing tall at the water’s edge is in plain view while one crouched or sitting is not; how a fish sees has the optics. Big bluegill also sit below the rest of the school, near the bottom, and the writers who chase them fish “quiet as a mouse” on 2–4 lb line.

Daily limits: from none to fifty

The bag limit says a lot about how a state sees its panfish:

The lower numbers rest on evidence. When Wisconsin cut seven lakes from 25 to 10 bluegill a day, the average bluegill grew 0.8 in (2 cm) longer, and on some lakes 2 in (5 cm). At Murphy Flowage, anglers under unlimited harvest took 90 percent of the bluegill over 8 in (20 cm) within three years. Check the current regulations before you fill a bucket; the tables change yearly, and Lake Erie’s total allowable perch catch was cut in both 2025 and 2026.

Are panfish good to eat?

Yes: the Missouri Department of Conservation calls bluegill flesh “firm, flaky, and well flavored”, and yellow perch is the fish-fry fish of the lower Great Lakes. The nuance is how often. Minnesota’s Department of Health puts sunfish in its one-meal-a-week category for everyone, based on average mercury, PFOS and PCB readings, while crappie from the same waters rate four meals a week. Yellow perch carry under 1 percent body fat, so the PCB concern is lower than for predators, though they can accumulate mercury; on the Hudson River below Catskill, white perch is limited to one meal a month for PCBs. The bluegill page and the coming can-you-eat-bluegill page carry the detail; the rule of thumb is that the small, short-lived sunfish you catch in a clean lake are among the safest fish in it.

Where to go next

The species pages arrive one by one: bluegill, yellow perch and white perch first, then rock bass, redear, pumpkinseed, green, longear and redbreast sunfish, the hybrid bluegill, a page on what “bream” means and one on everything called a perch. The crappie hub will cover black and white crappie, jigs, rigs and the record. For the fishing itself, pages on bluegill fishing, bluegill bait and bluegill lures and on perch fishing are on the way, and the world-record bluegill page will tell the Ketona and Havasu stories in full. Every other freshwater and saltwater fish lives under the species hub. What anglers mean by a slab or a bull is in the slang list of the fishing terms.
