Question: what is the difference between yellow lake perch and white lake perch?
Answer: Yellow Perch, however, are brownish-yellow in color, and boast distinct dark vertical bars. Another difference between the two species are the pelvic fins. On a White Perch, the pelvic fin faces downwards, and widens from the root out. Yellow Perch have a triangular pelvic fin, which points out in a 45-degree angle.
