Q.SST & Offshore Fishing
Why do blue marlin prefer warm water?
A.
Blue marlin are warm-water apex predators that thrive in 75-85°F SST. Their metabolism, prey availability (mahi, tuna, squid), and breeding cycles all align with tropical and subtropical water. They follow warm currents and seasonal SST shifts — Gulf Stream, Loop Current, and warm core eddies are their primary highways.
