Atlantic Mackerel
Catch clustered schools alive and turn the Fish Farm into a repeatable supply.
Best capture method
Net Gun. Catch stars measure quality, not rarity. Bring the target back alive whenever its rules allow it, and reserve Recovery Drone charges for large compatible fish.
Restaurant use
Atlantic Mackerel Sushi. Enhance this dish only when its ingredient route is repeatable; a stable Fish Farm supply beats a one-night spike.
