Spawn: 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.
