Genera [1]

The threadfin breams consist of the family Nemipteridae within the order Perciformes. They are also known as whiptail breams and false snappers.

They are found in tropical waters of the Indian and western Pacific Oceans. Most species are benthic carnivores, preying on smaller fishes, cephalopods, crustaceans and polychaetes; however, a few species eat plankton.

Threadfin bream harbour parasites. A study conducted in New Caledonia has shown that the fork-tailed threadfin bream ( Nemipterus furcosus ) harboured 25 species of parasites, including nematodes, cestodes, digeneans, monogeneans, isopods, and copepods. None of these parasites is transmitted to humans. [2]

Australasian snapper

The Australasian snapper or silver seabream, is a species of porgie found in coastal waters of Australia, Philippines, Indonesia, China, Taiwan, Japan and New Zealand. Its distribution areas in the Northern and Southern Hemispheres are disjunct. Although it is almost universally known in Australia and New Zealand as snapper, it does not belong to the snapper family, Lutjanidae. It is highly prized as an eating fish.

Mangrove red snapper

The mangrove red snapper, commonly called mangrove jack within Australia, is a species of snapper. It is also known as creek red bream, the Stuart evader, dog bream, mangrove red snapper, purple sea perch, purple sea-perch, red bream, red perch, red reef bream, river roman, or rock barramundi.

<i>Pristipomoides filamentosus</i> Species of fish

Pristipomoides filamentosus, commonly known as the crimson jobfish, crimson snapper, opakapaka, or Hawaiian pink snapper, is a species of snapper native to the Indian Ocean and into the Pacific Ocean as far east as Hawaii and Tahiti. They inhabit waters over rocky substrates at depths from 40 to 400 m seemingly preferring to remain between 180 and 270 m. This species can reach a length of 100 cm (39 in), though most are around 50 cm (20 in). The greatest known weight for this species is 8.2 kg (18 lb). This species is very important to local commercial fisheries and is sought out as a game fish. One of the Deep Seven species of Hawai'i.

Lutjanidae

Snappers are a family of perciform fish, Lutjanidae, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper.

Porgy fishing

Porgy is the common name in the US for any fish which belongs to the family Sparidae. They are also called bream. Porgies live in shallow temperate marine waters and are bottom-dwelling carnivores. Most species possess grinding, molar-like teeth. They are often good eating fish, particularly the gilt-head bream and the dentex.

Fish disease and parasites Disease that afflicts fish

Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens.

Coral reef fish Fish which live amongst or in close relation to coral reefs

Coral reef fish are fish which live amongst or in close relation to coral reefs. Coral reefs form complex ecosystems with tremendous biodiversity. Among the myriad inhabitants, the fish stand out as colourful and interesting to watch. Hundreds of species can exist in a small area of a healthy reef, many of them hidden or well camouflaged. Reef fish have developed many ingenious specialisations adapted to survival on the reefs.

Conservation biology of parasites

A large proportion of living species on Earth live a parasitic way of life. Parasites have traditionally been seen as targets of eradication efforts, and they have often been overlooked in conservation efforts. In the case of parasites living in the wild – and thus harmless to humans and domesticated animals – this view is changing.

<i>Huffmanela branchialis</i>

Huffmanela branchialis is a parasitic nematode It has been observed on the gills of the fork-tailed threadfin bream Nemipterus furcosus, a nemipterid marine fish off New Caledonia. Its eggs are released from the gill mucosa with the turnover of living tissues and immediately continue their life-cycle.

<i>Lethrinus atkinsoni</i>

Lethrinus atkinsoni is a species of emperor fish described by Alvin Seale in 1910. It is commonly 30 to 35 cm long with a bluish-grey, yellowish, or tan in colour, and a white belly. This species is widespread throughout the west Pacific Ocean. It is a reef-associated fish and is non-migratory. It is solitary or is found in small schools, and lives in seagrass beds and over the sandy bottoms feeding on plankton, mollusks, crustaceans, and other fishes. This fish is caught by humans for food, but less so than other species in the genus due to its small size.

<i>Lethrinus lentjan</i>

Lethrinus lentjan is a species of emperor fish. It has a distinctive blood-red colouration around the margin of the gill covers. It is widespread around the Indo-West Pacific, and is reef-associated. This species is fished commercially and for sport.

<i>Lethrinus nebulosus</i>

Lethrinus nebulosus is a species of emperor fish. Common names include spangled emperor, green snapper, morwong, north-west snapper, sand bream, sand snapper, sixteen-pounder, and yellow sweetlip.

<i>Lethrinus rubrioperculatus</i>

Lethrinus rubrioperculatus, common names the spotcheek emperor, red-eared emperor, red-ears, red-edged emperor, scarlet-cheek emperor, and spot cheek emperor, is a species of emperor fish.

<i>Lagenivaginopseudobenedenia</i>

Lagenivaginopseudobenedenia is a genus of monopisthocotylean monogenean, included in the family Capsalidae. The type-species of the genus is Lagenivaginopseudobenedenia etelisYamaguti, 1966. The genus includes only 2 species, which are both parasitic on the gills of marine fish of the family Lutjanidae.

<i>Nemipterus furcosus</i>

Nemipterus furcosus, the fork-tailed threadfin bream, also known as the rosy threadfin bream, is a species of threadfin bream native to Indian oceanic seas around Maldives, Sri Lanka, Andaman islands, and Pacific oceanic seas around Indonesia, and Australia. It inhabits areas with coral reefs at depths from 8 to 110 m. This species can reach a length of 24 cm (9.4 in), though most are only around 18.0 cm (7.1 in). It typically has a silver colored belly and red color on its dorsal, head and tail.
