How does the long lifespan of Grouper (up to 40 years) impact health risks?
Answer
It allows greater accumulation of contaminants over time.
The longevity associated with Grouper, with some individuals living for several decades, potentially up to 40 years, is a critical factor influencing its health profile related to contaminants. This extended lifespan provides a prolonged window during which the fish can continuously consume smaller prey. Consequently, this extended exposure time directly correlates with a greater opportunity to accumulate environmental toxins, such as mercury, and other potential poisons, like ciguatera toxins, within its tissues through the process of biomagnification. Therefore, older, larger fish carry a higher contaminant load.
