Probably to a much lesser degree but I'm going to say during the warmer summer months they tend to slow down compared to other species.
Yeah, that seems to match what I've seen. In my experience, perch are crazy aggressive, but less-so in the summertime.
Can I ask you a couple semi-related questions?
1. Is it possible for YP to be the apex predator in a pond that has BG?
2. YP are awesome to eat, but I'm a bit apprehensive about eating fish out of our pond. The landowner we share the pond with fertilizes the lawn around the pond in the spring. He also sprays Roundup on some of the weeds around the pond, despite the fact that I've asked him not to. Would that scare you away from eating the fish, or am I being overly cautious?
Thanks.
