Field photograph · reviewed 2026-08-29
Adult holding beside submerged wood in stained water. Identified on the upper jaw extending past the rear margin of the eye — the feature that separates largemouth from smallmouth — with the blotchy lateral band and deeply notched dorsal consistent. The wood is habitat context, not a location claim. Photographic: natural light shafts, coherent debris, plausible surface refraction.

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.
Those three links carry the fish and nothing else. No conditions were declared on this page, so none travel, and the link says so rather than sending an empty reading.
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 Largemouth bass there are 11 of them.

Absent from the record
2No 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 Largemouth bass was found that a review would accept. The reading runs without one rather than borrowing a number from a related fish.
- Population context
No regional population profile is registered. The species-level reading stands on its own; it does not silently become a local one.

LightShade and low light increase shallow positioning; bright high-sky days push into cover.
Thermal band
Temperature
No reviewed temperature band
Nobody publishes a preferred or active temperature range for Largemouth bass 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
Not a pelagic schooling bass. A group on a dock or weed edge is cover-associated, not a white-bass school.
Sight ambush from vegetation, wood, and shade. Forage classes include baitfish, crayfish, amphibians, and insects. Presence of a forage class is not observation of a current event.
Shade and low light increase shallow positioning; bright high-sky days push fish into cover. Daytime feeding still occurs, especially in stain.
Seasonal activityShallow cover in cool water; vegetation, wood, and shade remain the organizing idea in summer. Winter is a reduced-metabolism, deeper-or-tighter-cover problem rather than a generic 'deep' slogan.
Temperature-driven behaviourWarmwater fish. Cold water slows movement; extreme heat pushes fish to shade, deeper edges, or oxygenated inflows.
Depth movementShallow to mid; follows vegetation, wood, and shade more than a contour number.
Facing the currentAvoids sustained current; uses slack and cover even in rivers.
Water levelRising water can pull fish into newly flooded cover; falling water can concentrate remaining cover. This is a structure-class statement, not a spot.
ClarityClear water increases shade and cover dependence; stain can allow more open-edge positioning without implying a surface bite.
CoverWeed edges, inside and outside weedlines, wood, dock shade, and slow-water wood in rivers.
Open waterNot the default. Pelagic chasing is more a spotted-bass or temperate-bass problem.
Predator avoidanceCover first: weeds, wood, docks, shade. Open water is not the default.
TerritoryNesting males guard; outside spawning this is home-range cover use more than a continuously defended territory.
Spawning (conservation context)Nests in protected shallows as water holds in the mid-60s. Colonial or visible beds are a conservation choice, never a recommendation. Northern versus Florida-strain thermal edges differ.
Where the general rule stops
- Northern vs Florida-strain thermal edges differ; do not treat them as one fish.
What it can eat
Forage
- Small forage fish
- Crustaceans
- Amphibians
- Aquatic insects
- Larger prey fish
Adults feed largely on other fish and large invertebrates such as crayfish. Insects and amphibians matter more for smaller fish and in vegetated shallows. TPWD: adults feed almost exclusively on other fish and large invertebrates such as crayfish.
- Feeding style
- Opportunistic
- Feeding zone
- Mixed
Through the year
- Winter
- Fewer prey items; remaining crayfish and slower fish near cover rather than open-water bait chases.
- Spring
- Fish and crayfish as water warms. Nesting is conservation context, not a diet event.
- Summer
- Bluegill, shad, and other littoral fishes plus crayfish around vegetation and wood.
- Fall
- Baitfish become more important where shad or other schooling forage concentrate. Not a named-concentration claim.
By life stage
- Young of year
- Zooplankton then aquatic insects and tiny fish.
- Juvenile
- Insects, crayfish, and small fish.
- Adult
- Mostly fish and crayfish; amphibians and large insects remain possible.
Prey sizeAdults take larger sunfish, shad, and crayfish as gape grows. Cannibalism of smaller bass is documented.
Ontogenetic shiftInsectivory in YOY to a fish–crayfish diet in adults.
SubstitutionsVegetated natural lakes emphasize sunfish, amphibians, and crayfish. Reservoirs with pelagic shad can shift adults toward open-water baitfish without abandoning cover-oriented feeding.
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
Winter
- Where they sit
- Deeper edges of wood, docks, and outside weedlines rather than featureless basin.
- Feeding
- Reduced; remaining crayfish and slower fish near cover.
- Temperature
- Below the 48°F cold edge, activity compresses.
What that changesBottom-contact, drop-presentation, and stationary-bait remain the reviewed slow jobs.
Early spring
- Where they sit
- Transition from winter cover toward protected shallows as water climbs through the 50s.
- Movement
- Fish redistribute with warming; this is not a GPS path.
What that changesSubsurface slow-roll and stop-and-go as fish use mid-depth cover edges.
Spring
- Where they sit
- Protected shallows, inside weedline, wood, and docks.
What that changesReviewed stillwater families stay cover-oriented. Do not add an unreviewed sight-fishing family.
What would count against it
- publishing nest locations
- treating spawning as a bite window
Spawns as water holds in the mid-60s; nests in protected shallows. Nests are not a target class.
Summer
- Where they sit
- Weed edges, wood, dock shade, and the outside weedline.
- Depth
- Shallow to mid under cover; bright high-sky days push into shade.
- Temperature
- Preferred 65–78°F; 88°F warm edge is a shade/oxygen problem.
What that changesSubsurface slow-roll, stop-and-go, surface-retrieve, and drop-presentation — all already reviewed.
Fall
- Where they sit
- Points, weed edges, and remaining vegetation as baitfish group.
- Forage
- Baitfish can rise in importance where shad exist. Capacity is not a current event.
What that changesStop-and-go and subsurface slow-roll on edges; flowing water still uses pulse-jig and stationary-bait.
Spawning · Spring, Early summer
Spawns as water holds in the mid-60s; nests in protected shallows.
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
What to look at
- TPWD: upper jaw extends well behind the back margin of the eye when the mouth is closed.
- Spiny and soft dorsal fins are nearly separated by a deep notch; they are not a continuous fin.
- A definite dark lateral stripe along the side.
- Tongue typically lacks the sandpaper tooth patch of spotted bass.
- Catalog scientific name follows the northern largemouth (Micropterus nigricans) treatment; Florida-strain fish are a thermal/identity caveat, not a second record.
- Average adult length
- Common adults 12–18 in in many fisheries.
- Common angling size
- 12–18 in.
- Typical weight
- 1–4 lb in many waters; productive southern lakes produce larger averages.
- Maximum documented
- Trophy fish regularly exceed 10 lb in Florida-strain and some southern fisheries; world-class sizes are documented in agency trophy programs. Northern-strain maxima are typically lower.
- Longevity
- Often 6–10 years; older fish occur in lightly exploited waters.
What it gets confused with
- Spotted bass
- Spotted bass: jaw does not extend beyond the eye, dorsal fins are connected, rows of spots form stripes on the lower side, and a tooth patch is usually present on the tongue.
- Smallmouth bass
- Smallmouth: jaw does not extend beyond the eye, vertical bars rather than a horizontal stripe, bronze-brown color, connected dorsals.
