What major risk does applying uniform conservation efforts pose when managing genetically distinct yellowtail snapper stocks?
Answer
Overfishing a locally vulnerable stock while believing the overall regional population is stable
When genetically distinct stocks exist within a wide management area, applying a single, uniform set of conservation rules creates significant risks. If catch limits or regulations are based on the average health of the entire large population—perhaps combining a robust northern stock with a struggling southern stock—the management strategy can mask serious localized issues. For example, if the southern Gulf stock has lower recruitment success, overall good data could mask its decline until it is severely depleted, leading to localized collapse despite apparent regional stability.
