Spring:
* As the water warms up in spring, perch become more active and start feeding heavily to prepare for spawning.
* Spawning typically occurs in late April or early May, depending on the geographic location and water temperature.
Fall:
* Perch also become active in the fall as the water cools down and they prepare for winter.
* They may feed heavily during this time, and some species may even spawn again in late fall.
Other factors affecting perch activity:
* Water temperature: Perch are cold-water fish, so they are more active in cooler water.
* Oxygen levels: Perch need adequate oxygen levels to survive, so they may be less active in areas with low oxygen.
* Food availability: Perch are opportunistic feeders and will be most active when food is abundant.
* Weather conditions: Perch may be less active during periods of heavy rain or strong winds.
Note: There may be some variation in perch activity based on the specific species and geographic location. However, spring and fall are generally considered the best times to target perch.
