What factor, similar to trout flavor variation, might explain taste differences in perch from different bodies of water?
Answer
the local food chain, specifically the prey species available to the perch
Flavor variation in fish, including yellow perch, is often intrinsically linked to their diet. While the text notes trout flesh color and flavor change based on shrimp/bug versus minnow consumption, it suggests similar logic applies to perch. Perch feeding heavily on clean insects are likely to result in a cleaner-tasting final product compared to those feeding on bottom-dwelling fare in murkier water. Investigating the local prey species available to the perch in a specific body of water can often reveal the source of flavor variance.
