Dolphinfish

Dolphinfish are generally social and schooling fish, especially when they are young or of similar size. Juveniles and smaller adults often travel in large, fast-moving schools, which helps them hunt efficiently and avoid predators. As dolphinfish grow larger, they tend to become less social; mature males are often alone or in pairs with females rather than in big groups. Spawning occurs in warm tropical and subtropical waters throughout much of the year, though it tends to peak in warmer seasons or regions. Courtship typically occurs near the ocean surface, where males and females engage in close swimming displays. Males, distinguished by their more prominent foreheads, may pursue and circle females, displaying their vibrant colouration during courtship. Dolphinfish are pelagic spawners, meaning females release eggs directly into open water, where males fertilise them externally. A single large female can produce hundreds of thousands of eggs per spawning event, and spawning can occur several times per year. The fertilised eggs float freely in the plankton-rich surface layer, hatching within 2 to 3 days. The larvae are extremely vulnerable, but they grow rapidly and reach juvenile size in just a few weeks. Young dolphinfish often seek shelter among floating seaweed or debris, forming small schools that provide protection and feeding opportunities. Growth is fast, with individuals capable of reaching sexual maturity within 4 to 5 months and attaining over a metre in length within their first year. The dolphinfish exhibits a rapid and prolific reproductive cycle that reflects its short lifespan and fast growth rate.
