Perchaude: 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.

Almost nothing on this page translates. Perch spawn weeks before bass even stage — right after ice-out, at 7–12 °C (45–54 °F) — and they do it without a single one of the behaviors this article is built on. There are no beds: females drape long, accordion-folded gelatinous egg ribbons over weeds, brush and fallen wood in roughly 0.5–3 m (2–10 ft) of shallow bay, often in low light, attended by a scrum of males. There is no defence and no parental care — the ribbon is abandoned the moment it is laid — so there is nothing to sight-fish, nothing to provoke, and no ethical debate about pulling guardians off nests. The act itself is brief, and the bite dips only briefly around it; fish that finish go straight back to eating. Now flip the page's perspective: when bass on the same lake finally do bed, at 17–20 °C (62–68 °F), perch are weeks past done, grazing hard — and small perch are enthusiastic nest raiders, gathering around bass beds to steal eggs and fry. That guarding male smashing your tube is often striking a perch impersonator, and a school of perch hanging off a spawning flat marks where the beds are. Takeaway: at ice-out, fish the weedy bays for pre- and post-spawn feeders rather than spawners; in bass season, remember the perch is on the other side of this page — as the raider, and as the reason bed-guarding exists.
