Crappie: Spawn
Interpret spawning from warming history, nests, guarding behaviour and fry, not a month alone. A Canadian cold spring can leave some fish spawning while others are already feeding after spawning. Nest building, egg laying and guarding are separate stages; a published spawning-temperature range is not an exact trigger. A population spawning in waves does not establish that every female lays two to five batches. Fish within local rules and avoid disrupting guarding fish.
Read the bass spawn article first, then apply three crappie edits. Timing: crappie beat bass to the beds, spawning at 14–20 °C (57–68 °F) — March–April in southern reservoirs, May into June in Ontario, typically a few weeks before largemouth in the same lake. Architecture: crappie are colonial. Males fan dozens of nests together on dark-bottomed bays, around reeds, brush, and stumps, usually 0.5–2 m (1.6–6.6 ft) deep — deeper and less visible in clear water, so this is less a sight-fishing game than bass bedding and more a "find the colony" game: catch one male and you've found fifty nests. Defense: like bass males, nesting crappie strike what invades — a 1/16 oz (1.8 g) jig under a float, held over the colony, gets crushed by fish that aren't feeding at all.
Females are only shallow in waves and briefly; the big ones hang on the first break outside the colony between visits, so the biggest fish of "the spawn" are often caught 2–4 m (6.5–13 ft) out, not on beds.
Conservation note honestly: a colony concentrates a lake's spawners in one spot, and keeping a limit off beds every day hits small lakes hard. Take a meal, move on.
Takeaway: search the back of dark-bottom bays a few weeks before bass bed; one caught male means a colony — fan out from him, and check the break outside for the slabs.

What is happening
Interpret spawning from warming history, nests, guarding behaviour and fry, not a month alone. A Canadian cold spring can leave some fish spawning while others are already feeding after spawning. Nest building, egg laying and guarding are separate stages; a published spawning-temperature range is not an exact trigger. A population spawning in waves does not establish that every female lays two to five batches. Fish within local rules and avoid disrupting guarding fish.
Where the fish are
Look for suitable firm substrate with protection from excessive waves and current. Males may guard nests or fry while other adults feed nearby. Nest depth varies with clarity and available habitat; females need not all retreat deep immediately.
How to fish it
Distinguish feeding/cruising fish from fish repeatedly returning to a nest or fry. Fish only within local seasons and rules. In a cold Canadian spring, a calendar label of early summer is not evidence that reproduction has finished.
