What factor, influenced entirely by the fish's recent diet, can cause a subtle difference in the flavor profile of fresh whiting purchased by a home cook?

Answer

The abundance of krill intake preceding harvest

The nutritional quality and flavor profile perceived by the consumer are directly traceable back to the whiting's foraging success. While whiting is generally lean, the fat content, including beneficial omega-3 fatty acids, varies seasonally based on feeding success. A whiting harvested immediately after consuming an abundance of krill (euphausiids) will possess slightly higher levels of these fats, resulting in a marginally richer flavor profile compared to a fish caught during a lean period, such as the winter months when feeding might be less successful.
