More Info


Distribution

Recorded from all Australian states except the Northern Territory. Elsewhere, the species is widespread in the tropical and temperate Indo-Pacific, and into the eastern Atlantic.

This oceanic epipelagic species usually occurs well offshore over deeper waters. It rarely enters coastal areas, and is less common that other billfishes throughout its range.

Features

Dorsal-fin 45-50 + 6-7; Anal fin 12-15 + 6-8; Pectoral fin 17-19.

Body elongate and fairly compressed. Bill short (less than 15% of body length) and slender. Lower jaw projecting but shorter than upper jaw (bill). Pectoral fins narrow and less than 15% of body length. Pelvic fins slender and approximately twice the length of the pectoral fins. The first dorsal fin height decreases after the high anterior lobe to about the 19th ray, after which the height increases again. Both jaws and palatines have fine, file-like teeth. Body covered in dense, bony scales each which 3-5 posterior points.

Size

Reaches 230 cm TL and 52 kg. On average, females are slightly larger than males. The all-tackle game fish record is of a 50 kg fish caught in Botany Bay, Sydney, Australia in 2008 (IGFA 2011).

Colour

Dark blue dorsally, blue with brown along the sides and silvery-white ventrally. First dorsal dark blue, other fins dark brown. Anal fin base tinged silvery-white.

Feeding

Feed at or near the surface on small to medium-sized pelagic fishes and squids.

Biology

Spawning appears to occur during winter, in warm offshore currents (above 24 degrees). Eggs are spherical and range in size from 1.3 to 1.6 mm in diameter. Larvae are pelagic.

This fish can weigh up to 52 kg. Average length of fish caught in long lines is 135cm eye fork length in the eastern Pacific. Maximum size is about 2 m and 52 kg in weight. Females are on average slightly larger than males.

Fisheries

No specific fishery in Australian water, but the species is targeted by commercial tuna longlines and is occasionally taken by recreational trolling. Commercial catches are highest in surface waters with bottom depths in the 915-1800 m range.

Conservation

  • IUCN Red List : Data Deficient

  • This highly migratory species is listed under Annex I of the 1982 Convention on the Law of the Sea (FAO Fisheries Department 1994).
