11 things this record does not know

Take this somewhere

This page is the record. The reading is what happens when you add water, a season and a temperature to it — that is where the families below get ranked against each other instead of just listed.

The half nobody publishes

What this record does not know

Everything else on this page comes from a named agency or peer-reviewed source. This is the other side of that: the questions a reviewer went looking for an answer to and came back without, and the fields the record leaves empty because filling them would mean guessing.

It is here rather than at the bottom because a page that only shows what it knows is easy to read as a page that knows everything. For Redear sunfish there are 11 of them.

Absent from the record

3

No reviewer wrote a gap here. The field is simply empty, which is its own answer.

Water temperature

No agency or peer-reviewed temperature band for Redear sunfish was found that a review would accept. The reading runs without one rather than borrowing a number from a related fish.

Identification

No reviewed image. A photograph is only in this catalog when an agency or a named creator labelled the subject, and nobody has cleared one for this species yet.

Population context

No regional population profile is registered. The species-level reading stands on its own; it does not silently become a local one.

Where the record puts it

Water and range

Warm clear ponds, reservoirs, lakes, marshes, and slow protected river habitat of the South and stocked waters elsewhere.

DepthOften uses slightly deeper littoral water than bluegill and feeds near bottom around vegetation, sand, mud, and shell-bearing substrate.

Moving waterPrefers still water or protected overflow pools and bays; avoids sustained main-channel current.

LightMostly active in daylight; bright clear conditions can shift fish deeper while preserving bottom and cover association.

Thermal band

Temperature

No reviewed temperature band

Nobody publishes a preferred or active temperature range for Redear sunfish that a review would accept. Borrowing one from a related fish would look like knowledge and behave like a guess, so the reading runs without it and says which parts of the answer that weakens.

How it uses water

Behaviour

Mollusks are a defining forage class, but insect and crustacean feeding remains important where snails are sparse. Nesting colonies are never named as target locations.

Missouri DNR: carnivorous, feeding primarily on snails and other mollusks — the shellcracker name. Throat teeth crush shells. Insects and crustaceans remain capacity. This is not a current snail declaration.

Missouri DNR: most active in daylight. Bright clear conditions can shift fish deeper while preserving bottom and cover association.

Seasonal activitySpawning commonly in warm shallow water around 70–75°F, often somewhat deeper than bluegill nests. Conservation context. Summer remains a bottom-and-mollusk problem.

Temperature-driven behaviourPreferred band roughly 72–81°F. Cold edge near 52°F; warm edge near 90°F. A warmwater, still-water fish.

Depth movementOften slightly deeper littoral water than bluegill, still near bottom.

Facing the currentStill water or protected overflow pools and bays. Avoids sustained main-channel current (Missouri DNR).

CoverWeed edges, outside weedlines, wood, shallow flats, and drop-offs — as bottom, not as a bluegill surface edge.

Open waterNot a pelagic schooler. Open water is not the job.

Predator avoidanceDepth, vegetation, and bottom. Bright surface water is a poor default.

TerritoryBottom and cover, not a current core. Nesting males defend closely packed saucers.

Spawning (conservation context)Missouri DNR: nesting in May or June, sometimes again in August; saucer-shaped colonies with rims often almost touching. Colonies are excluded from target guidance.

Where the general rule stops

  • Mollusks are a defining forage class, but insect and crustacean feeding remains important where snails are sparse.
  • Nesting colonies are never named as target locations.

What it can eat

Forage

A capacity list, not a report from this week. What is actually available on your water is a separate question, and Hatch Match is the tool that asks it.
  • Mollusks
  • Aquatic insects
  • Crustaceans
  • Worms / annelids

Missouri DNR: feeding primarily on snails and other mollusks — the shellcracker name. Insects, crustaceans, and worms remain important where snails are sparse. Zooplankton and small forage fish are not catalog classes on this record.

Feeding style
Specialized
Feeding zone
Benthic

Through the year

Winter
Remaining benthic invertebrates on the bottom of the usable band.
Spring
Mollusks and insects as water warms. Spawning overlap is conservation context.
Summer
Snails and other mollusks on vegetation, sand, mud, and shell substrate. Insects where snails are sparse.
Fall
Mollusks and remaining benthic invertebrates.

By life stage

Young of year
Agency pond notes describe zooplankton-scale feeding in fry; zooplankton is not a catalog class here. Insects follow.
Juvenile
Small mollusks and insect larvae.
Adult
Primarily snails and other mollusks; insects and crustaceans remain possible.

Ontogenetic shiftInsects to primarily mollusks.

SubstitutionsSnail-poor water substitutes insects and crustaceans. That does not turn this record into a bluegill.

Diet capacity is not proof that a hatch or prey event is occurring. Observed current forage still comes from a user observation or Hatch Match.

Through the year

Season

Redear calendars are bottom-and-mollusk calendars, often slightly deeper than bluegill. They are not a surface sunfish. Nesting colonies are conservation context.

Winter

Where they sit
Deeper weed edges, drop-offs, and remaining bottom cover in the usable band.
Feeding
Slow bottom intercept of remaining invertebrates.

What that changesBottom contact, slow drag, and drop presentation.

Spring

Where they sit
Weed edges, outside weedlines, and shallow flats as water warms toward 70–75°F.

What that changesSlow drag, drop presentation, and bottom-contact drift in protected slack.

What would count against it

  • using nesting colonies as holding water

Spawning commonly in warm shallow water, often somewhat deeper than bluegill nests. Colonies are excluded from target guidance.

Summer

Where they sit
Weed edges, outside weedlines, wood, and drop-offs — as bottom, not as a surface edge.
Depth
Often slightly deeper littoral water than bluegill.
Temperature
Preferred 72–81°F. Most active in daylight.

What that changesBottom contact, slow drag, drop presentation, and live / natural bait suspension. Pulse / jig on the bottom of protected water.

What would count against it

  • forcing a bluegill surface default this record does not have

Fall

Where they sit
Outside weedlines and drop-offs as water cools.
Forage
Mollusks and remaining benthic invertebrates. Do not infer a snail event from the calendar.

What that changesBottom contact, slow drag, and stationary bait.

Spawning · Spring, Early summer, Summer

Spawning commonly occurs in warm shallow water around roughly 70-75°F, often in colonies and somewhat deeper than bluegill nests.

Recorded as conservation context. No spawning site, staging concentration or migration bottleneck is named anywhere in this catalog, because naming one is how a population gets fished out.

Telling it apart

Identification

Dark olive above to yellow or orange-yellow on the belly; sides yellow-green, often with faint bars. The red or orange flap edge is the namesake mark.

What to look at

  • Texas Parks and Wildlife: the most distinct character is the red edge on the opercle flap of the male (orange on the female). The flap is never greatly elongated.
  • Missouri DNR: ear flap black with a whitish border and a prominent orange or red spot/edge. Pumpkinseed’s flap is a discrete red spot with a white margin plus wavy blue cheek lines — redear lack that cheek maze.
  • No bluegill-style black spot at the rear of the soft dorsal. Pectorals long; mouth small.
  • Texas Parks and Wildlife: typically 10 dorsal spines and three anal spines. Sides often show faint vertical bars on olive-to-gold ground.
  • Pharyngeal (throat) teeth are broad and flattened for crushing mollusk shells (Missouri DNR). That is diet anatomy, not a field-visible ID for most anglers.
Average adult length
Missouri DNR: total length commonly 8–10½ in.
Common angling size
8–11 in in ponds and reservoirs where snails are present.
Typical weight
Missouri DNR: commonly 6½–12 oz.
Maximum documented
Missouri DNR: can be more than 12 in and more than 4 lb. Those maxima are waterbody-specific.
Longevity
Missouri DNR: individuals can live for 6 years.

What it gets confused with

Bluegill
Bluegill have a plain black ear flap and a soft-dorsal spot. Redear have the colored flap edge and lack that dorsal spot.
Pumpkinseed
Pumpkinseed have a discrete red-orange flap spot, a white margin, and wavy blue cheek lines. Redear have a colored flap edge and lack the cheek maze.
Green sunfish
Green sunfish have a large mouth and an elongated body. Redear mouths are small.

What follows from all of that

Presentation families

These are the families the record will consider for this fish, and what each one has to do. They are not ranked here — ranking needs a season, a temperature and a piece of holding water, which is what the reading is for.
