Correct !!
And you wanna know something funny .... I was probably around 30yrs old before I realized that what my friends & locals around here were calling "white perch" ... were actually Freshwater Drum Seriously, I grew up calling Freshwater Drum as "white perch" !!
And as a pre-teen kid living & growing up with my Grandparents, who were avid Crappie anglers, I was "tricked" into thinking we were going fishing for a new species of fish when my GramPa said we were going fishing for "Newlights" I had heard him mention "Newlight waves" when there was a light wind ripple on the water, and even though I knew we were fishing for Crappie ... I never made the connection until I was older.
I've read where Crappie nicknames include "Strawberry Bass", "Bachelor Perch", "Calico Bass", or "Speckled Bass/Perch" ... but I've never heard anyone use those nicknames. Now, I've only fished in KY, Tenn, SC, & Ala. so those nicknames may not have been used in those parts, but I've never heard them called "White Perch" in any of those areas, either.
I mean no disrespect when "correcting" .... it's just that after 45yrs of working in the Pharmaceutical/Medical field, I've just picked up the habit of being precise.
