How can observing the stomach contents of whiting over multiple years provide actionable information to fishery scientists?
Answer
It can function as an early warning system for broader ecosystem stress affecting key prey items.
Analyzing the stomach contents of whiting across several years offers a powerful, lagged indicator of overall ecosystem health. If key prey items, such as juvenile rockfish or sand lance, begin to decline due to environmental shifts, the whiting's diet composition will reflect this scarcity, potentially showing slower growth or reduced recruitment in the predator population. This observation precedes the point where those effects become visible in larger apex predators, thus positioning the whiting's diet analysis as a sophisticated, early warning mechanism for tracking subtle, long-term stress within the marine environment.
