When they get that big, they fight like a bass!! In late summer, I started catching 13-14" crappie and the strike & fight were powerful!
There will always be levels of fish excitement, from zero to super aggressive. School crappie can be the most aggressive and once one is hooked, I can throw the fish back into the school and still catch fish after fish. I've found that this applies to all predator species that school. So much for the old fish tale: don't return a fish to where you caught it because it will spook the rest.
