Fish spawning temperature chart
Spawning is triggered more by water temperature than by the date on the calendar. This chart lays out the typical spawning window for 53 common freshwater fish, from the cold-water species that spawn right after ice-out to the catfish that wait for real summer warmth. Read it alongside the today's conditions and what's biting pages to time a trip.
These are typical ranges compiled from general fisheries figures. Actual timing shifts with latitude, season length, water body and the weather that year, and it can vary within a species across its range. Use it as a guide, not a guarantee, and always follow your local seasons and regulations.
One of the only freshwater fish to spawn under the ice in midwinter.
Spawn soon after ice-out over gravel in cold northern streams.
Cut redds in gravel riffles in late autumn.
An autumn spawner drawn to cold spring seeps and clean gravel.
Spawn in small tributaries through late fall into early winter.
Broadcast eggs over shallow rocky shoals as water chills in late fall.
One of the very first to spawn, scattering eggs over flooded vegetation right after ice-out.
Run up rivers to spawn slightly cooler than walleye.
Needs the coldest, cleanest water; spawns in fall in headwater gravel.
Return to natal rivers and dig deep redds as water cools in fall.
A spring spawner that cuts redds in clean gravel with good flow.
Spawn in streams and lake shorelines linked to nursery lakes.
Sea-run rainbows that spawn in spring in gravel-bottomed rivers.
Run to rocky shoals and river tailouts right after ice-out, one of the earliest spawners.
Spring spawner that runs up cold tributaries to clean gravel.
Spawns in autumn as water cools, digging redds in gravel riffles.
High-country spawner that waits for alpine streams to warm in early summer.
Drape ribbon-like egg strands over weeds and brush soon after ice-out.
Spawn in the lower reaches of coastal streams late in the year.
Landlocked sockeye that spawn in tributaries and shorelines in fall.
Spawn low in coastal rivers, often close to the tide.
An early spawner that scatters eggs over shallow weeds.
Broadcast eggs over rocky reefs in fall, with no nest built.
Spawns a few weeks after pike over shallow, sheltered flats.
Move into rivers and coves to broadcast eggs in spring.
Run to rocky rapids and shorelines to spawn, once every few years per fish.
Make a heavy river run to spawn over gravel and hard bottom.
Make a strong upriver run from the sea to spawn in flowing water.
Move shallow to spawn as water reaches the upper 50s and low 60s, a classic early-spring bite.
Spawns on rock and gravel, often a little deeper than largemouth.
Run far up rivers to broadcast eggs that need current to stay suspended.
Beds appear on gravel and rock as water climbs into the low 60s, a touch later than largemouth.
Males build weedy nests and guard the fry aggressively.
A Texas stream native that beds over gravel in flowing water.
Males fan beds in shallow flats and coves once water holds in the low 60s.
Nests near rock and cover in cooler, clearer water than bluegill.
Thrash noisily in flooded shallows and weed beds through late spring.
Spawns on rocky shoals and current breaks in southeastern rivers.
Broadcast buoyant eggs into open water, unusual among freshwater fish.
Guard nests in hollow logs and holes through early summer.
Gather in shallow, weedy water to scatter sticky eggs.
Colonial bedders that spawn in waves through summer once water passes the upper 60s.
Need warm floodwater over vegetation to trigger spawning.
Need warm, rising river water to broadcast their drifting eggs.
Tolerant spawner that beds in warm, shallow, often marginal water.
Nests in shallow weedy margins alongside bluegill.
Cavity nesters that spawn as water settles into the 70s.
Nest in shallow, weedy, often muddy water and fiercely guard the fry.
Beds over gravel and sand in clear streams and lake edges.
Beds a little warmer than bluegill, often on firmer bottom.
A warm-water sunfish that beds near stumps and weedy cover.
Wait for real summer warmth, then nest in dark cavities and undercuts.
A tropical fish that needs consistently warm water and guards nests as a pair.
How to use water temperature
A cheap stick thermometer or a fish-finder's surface reading is enough. When the surface climbs toward a species' window, fish start staging near the areas where they spawn, and that pre-spawn period is often the best fishing of the year. Once fish are actively on beds, handle them quickly and return them so they can finish the job. For catch-and-release best practice see the catch and release guide.
