Which specific temperature range is cited as the preference for yellowfin tuna?
Answer
Approximately 62°F to 86°F (17°C to 30°C)
The ideal oceanographic conditions for yellowfin tuna are defined precisely by temperature; they thrive in warmer waters but have an upper limit before conditions become unfavorable. The established preference centers around a range starting near 62 degrees Fahrenheit, or 17 degrees Celsius, extending up to 86 degrees Fahrenheit, or 30 degrees Celsius. This temperature constraint, along with food availability dictated by currents, dictates their distribution patterns globally, influencing where commercial fleets and anglers focus their efforts.
