Mahi mahi

   The Mahi-mahi, scientific name: Coryphaena hippurus, is a pelagic migratory fish belonging to two closely related species. Its body is elongated and laterally compressed, high at the front and tapering towards the rear; males have a bony ridge on their heads, while females have a nearly square head and back. The maximum body length can reach 2.1 meters. Its body surface possesses an iris cell layer that can change color through contraction and expansion; when calm, it is silvery-blue, turning golden-green with vertical stripes when excited, and fading to grayish-brown after death.

   Mahi-mahi are widely distributed in tropical and subtropical waters worldwide, typically inhabiting surface waters and preferring to congregate in the shade of drifting debris. They feed on small fish and invertebrates, are fast swimmers, and voracious eaters, consuming up to 20% of their body weight daily. The southern Yellow Sea to the northern East China Sea is their wintering ground, and they migrate to the coast to spawn in spring. Their flesh is delicious, making them a target for sea fishing and commercial fishing; in Hawaii, they are called "mahi-mahi".

   Juvenile mahi-mahi can be found year-round in waters with a temperature of 28 degrees Celsius (82 degrees Fahrenheit), with higher numbers in spring and autumn. Mahi-mahi primarily inhabits surface waters. The raw flesh is grayish-white, turning an appealing white when cooked. It has a mild flavor and no fishy taste.
