Legal size: 35cm. They grow 80 cm and don`t seem to clear well, so if you land one, you might as well keep it.

The color of the golden mackerel is the most striking distinguishing feature of the species for which it got its common names. Juveniles have a bright golden yellow color all over their body and fins, with 7 to 11 black vertical crossbars all over the body. These bars usually alternate between wide and narrow. The lobes of the caudal fin have dark ends and there is a distinctive black border on the operculum. As the fish grows, the body becomes more silvery to silvery golden and the crossbars fade or disappear, often replaced by dark spots.
The fins remain yellow, often with greenish tones. The dark edge of the operculum also fades with age. [10] [14] The dolphinfish (Gnathanodon speciosus) is a species of mackerel in the Carangidae family. The dolphinfish is widespread in tropical and subtropical waters of the Indian and Pacific Oceans, from South Africa in the west to Central America in the east, Japan in the north and Australia in the south. The species mainly inhabits coastal waters, where it inhabits both reef and sandy substrates. Golden mackerel is slightly distinguished from its parents by its plump, rubbery lips and unique coloration, ranging from bright yellow with black bars in adulthood to golden-silver color. It is known to grow to 120 centimeters (47 inches) long and weigh 15 kilograms (33 lbs). Golden mackerel train in a juvenile state and often follow larger objects such as sharks and jellyfish. The species uses its protractable jaws to suck its prey out of the sand or reef, and eats a variety of fish, crustaceans and molluscs. Spawning accumulations accumulate at night at different times of the year throughout their range.
The dolphinfish is an important component of several fisheries in the Middle East and of minor importance to many others, with an annual global catch ranging from 1,187 tonnes (1,168 long tons; 1,308 short tons) to 3,475 tons (3,420 long tons; 3,831 short tons) between 2000 and 2010. Golden mackerel is a popular wild fish caught by bait, bait, fly and spears throughout its range. Several Asian countries currently raise fish in cage aquaculture. Due to their bright coloring, young animals are popular in saltwater aquariums. Spanish can be found around coastal headlands, up to the Great Barrier Reef. In winter, they migrate in greater numbers to coastal waters and are an important destination for a fisherman in a small boat. These school-sized fish are about 15 kg, but sometimes 30 kg+ also appear. Smaller individuals have a row of small villi teeth in both jaws. [13] The dorsal fin consists of two parts, the first with 7 spines, the second with 1 spine and 18 to 20 soft rays. The fin has 2 detached spines, followed by 1 spine and 15–17 soft rays,[15] while the pelvic fin consists of 1 spine and 19–20 soft rays. [13] The curved portion of the lateral line is moderately arched; with 62 to 73 scales and about the same length as the straight section with 15 to 27 scales and 18 to 25 scales. The breast is completely scaled.
[10] [13] In total, there are 27 to 30 gill rakes and 24 vertebrae. [15] The dolphinfish mainly occupies coastal waters with different substrates, although it is known to be found on deeper continental reefs in Australia. [10] In coastal areas, the species inhabits rocky and coral reefs as well as open sandy areas, where it feeds. [12] [15] A systematic review in northern Australia showed that it is one of the few species that is almost evenly distributed in reef and soft-bottom habitats. [16] Golden mackerel appears to prefer clear water to murky waters,[10] and is therefore rarely found in low turbidity environments. [17] A known exception was the capture of several individuals in a shallow mangrove in Baja California, which appeared to be searching for prey. [18] Includes, but is not limited to, mackerel and scad/yacca. Small juveniles of the species of golden mackerel sometimes live between the tentacles of some frosts.
