Wahoo (Acanthocybium solandri) is a scombrid fish found worldwide in tropical and subtropical seas. It is best known to sports fishermen, as its speed and high-quality flesh makes it a prized and valued game fish.

Contents

Description

Its body is elongated and the back is an iridescent blue, while the sides are silvery with a pattern of irregular vertical blue bars. These colors fade rapidly at death. The mouth is large, and the teeth of the wahoo are razor sharp. Both the upper and lower jaws have a somewhat sharper appearance than those of king or Spanish mackerel. Specimens have been recorded at up to 2.5 m (8 ft 2 in) in length, and weighing up to 83 kg (183 lb). [3] [4] The growth of the fish can be quite quick. [4] They are among the fastest fish in the sea.[ citation needed ]

The wahoo may be distinguished from the related Atlantic king mackerel and from the Indo-Pacific narrow-barred Spanish mackerel by a fold of skin that covers the mandible when its mouth is closed. In contrast, the mandible of the king mackerel is always visible, as is also the case for the smaller Spanish mackerel and Cero mackerel. The teeth of the wahoo are similar to those of king mackerel, but shorter and more closely set together.[ citation needed ]

The barracuda is sometimes confused with the mackerel and wahoo, but it is easy to distinguish from the latter two species. Barracuda have prominent scales and larger, dagger-like teeth, and lack the caudal keels and blade-like (forked) tail characteristic of the scombrids.[ citation needed ]

Distribution

Wahoo have a circumtropical distribution and are found in Atlantic, Pacific, and Indian Oceans. [5] Population genomic research using RAD sequencing indicates that two weakly differentiated fish stocks are in the Atlantic and Indo-Pacific Oceans, likely with a considerable degree of migration and gene flow between these populations. [5]

Life cycle

The eggs of the species are buoyant and the larvae are pelagic. [5] Wahoo tend to be solitary [6] or occur in loose-knit groups of two or three fish. [7] Where conditions are suitable, they can be found in schools around 100 or more.[ citation needed ]

Ecology

Their diet is made up of other fish and squid. [4] From a study surrounding the Western and Central Pacific Ocean (WCPO), an analysis of the stomach contents of wahoo indicated that their diet consists of 84.64% native fish, 14.26% cephalopods (e.g. cuttlefish), and 1.1% crustaceans. The gender ratio of wahoo favors females over males with ratios ranging from 1:0.9 (Puerto Rico) to 3.5:1 (North Carolina), which is common for most pelagic marine species. [8]

Most wahoo taken from waters have a trematode parasite, the giant stomach worm (Hirudinella ventricosa), living in their stomachs, but it does not appear to harm the fish. [9] [10]

Fisheries

Wahoo catch

The flesh of the wahoo is white and/or grey, delicate to dense, and highly regarded by many cuisines. The taste has been said to be similar to mackerel. [11] This has created some demand for the wahoo as a premium-priced commercial food fish. In many areas of its range, such as Hawaii, Bermuda, and many parts of the Caribbean, local demand for the wahoo is met by artisanal commercial fishermen who take them primarily by trolling.[ citation needed ]

Commercial

Although local wahoo populations can be affected by heavy commercial and sport-fishing pressure, wahoo as a species is less susceptible to industrial commercial fishing than more tightly schooling and abundant species such as tuna. Wahoo are regularly taken as a bycatch in various commercial fisheries, including longline fisheries for tuna, billfish, and dolphinfish (mahi-mahi or dorado). It is also taken in tuna purse seine fisheries, especially in sets made around floating objects, which act as a focal point for a great deal of other marine life besides tuna. In 2003, the South Atlantic Fishery Management Council issued a Dolphin Wahoo Fishery Management Plan for the Atlantic. [12] [13] The species as a whole, though, is not considered overfished. [12]

Recreational

In most parts of its range, the wahoo is a highly prized sport-fishing catch. [6] It reaches a good size, and is often available not too far from land; it is also a very good fighter on light to medium tackle. It is known in sport-fishing circles for the speed and strength of its first run. Recreational sports fishermen sometimes sell their catch.[ citation needed ]

Wahoo are most successfully fished with live bait around deep-water oil and gas platforms in the Gulf of Mexico during the winter. [14]

Local names

In Hawaii, the wahoo is known as "ono". [15] The species is sometimes called "hoo" in the United States. [14]

Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear.

The albacore, known also as the longfin tuna, is a species of tuna of the order Scombriformes. It is found in temperate and tropical waters across the globe in the epipelagic and mesopelagic zones. There are six distinct stocks known globally in the Atlantic, Pacific, and Indian oceans, as well as the Mediterranean Sea. The albacore has an elongate, fusiform body with a conical snout, large eyes, and remarkably long pectoral fins. Its body is a deep blue dorsally and shades of silvery white ventrally. Individuals can reach up to 1.4 m in length.

<span class="mw-page-title-main">Billfish</span> Group of fishes

The billfish are a group of saltwater predatory fish characterised by prominent pointed bills (rostra), and by their large size; some are longer than 4 m (13 ft). Extant billfish include sailfish and marlin, which make up the family Istiophoridae; and swordfish, sole member of the family Xiphiidae. They are often apex predators which feed on a wide variety of smaller fish, crustaceans and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group which originated around 71 million years ago in the Late Cretaceous, with the two families diverging around 15 million years ago in the Late Miocene. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.

A fish aggregatingdevice (FAD) is a man-made object used to attract pelagic fish such as marlin, tuna and mahi-mahi. They usually consist of buoys or floats tethered to the ocean floor. Various types of FADs have been employed in the traditional fishing cultures of Island Southeast Asia, Japan, and Malta for centuries. Modern FADs are increasingly being used in modern commercial and sport fishing.

Marlin fishing or billfishing is offshore saltwater game fishing targeting several species of fast-swimming pelagic predatory fish with elongated rostrum collectively known as billfish, which include those from the families Istiophoridae and Xiphiidae (swordfish). It is considered by some fishermen to be a pinnacle of big-game fishing, due to the size, speed and power of the billfish and their relative elusiveness.

Rexea solandri, the silver gemfish, is a species of snake mackerel found in the southwestern Pacific Ocean around Australia and New Zealand with reports of possible records from Madagascar and Japan. Gemfish appear as infrequent, but regular bycatch species in pelagic longline fisheries for tuna in the waters around the Hawaiian archipelago and American Samoa. This species occurs in schools at depths of between 100 and 800 metres, though mostly between 300 and 450 metres. This species can reach a length of up to 110 centimetres (43 in) SL and a maximum weight of 16 kilograms (35 lb) has been recorded. This species is important to local commercial fisheries.

Fishing is important to the national economy of Vanuatu. It is the main source of income for many in the islands and Vanuatu's biggest export. According to 2009 figures, approximately 77% of households in Vanuatu are involved in fishing activity. According to 2005 figures, Vanuatu caught 151,080 fish in that year, with frozen fish accounted for half of Vanuatu's commodity exports.
