Why does Ocean Perch hold up better to baking or broiling than freshwater perch?

Answer

Its medium fat content helps prevent it from becoming dry

The Atlantic Redfish, marketed as Ocean Perch, possesses a medium fat content that contributes significantly to its moistness, even when subjected to more aggressive cooking techniques like baking or broiling. This inherent level of fat provides a buffer against drying out that the leaner freshwater Yellow Perch, with its more delicate structure, lacks. Consequently, the firmer texture and greater fat retention of the ocean variety allow it to be used successfully in heartier preparations where the freshwater species might easily become overcooked and dry.
