The famous “Kingy”! A much sought after species, the fighting qualities and sheer size of large Yellowtail Kingfish make them a prized catch for just about any spearfisher. Found around headlands, islands and occasionally in estuaries, any spot holding large amounts of baitfish near deepwater is a likely spot to see a Yellowtail Kingfish.
This species has “counter-shaded” body, with a greenish-silver dorsal surface, a dark stripe along the lateral line from head to tail, and a white belly. The yellow coloured tail stands out quite strongly underwater, and a good indication of large size is a relatively small tail. This species is confused with the Amberjack (Seriola dumerili) and the Samson fish (Seriola hippos) which have a similar body shape, but lack the yellow tail and have a dark stripe running diagonally through the eye.
Male Kingfish mature at around one year of age and 47cm fork-length, whereas females take longer to reach breeding age at 4 years and 83cm fork-length. This species spawns in the spring-summer period, the young fish stay well offshore until 40-50cm in length. Maximum age for this species is over 20 years.
Kingfish are often targeted using flasher or burley to attract the fish towards the diver. The best approach to get into range seems to be to simply wait for the fish to approach whilst hanging in mid-water. A speared fish will often be surrounded by other Kingfish, so a quick dive on a fish another diver has speared will often result in another capture. The recreational catch for this species is estimated to be between 120 and 340 tonnes per year.
