The Upper Zambezi labeo (Labeo lunatus) is a species of cyprinid fish of the genus Labeo native to southern Africa. [2]
This species occurs in the Upper Zambezi and Okavango Rivers, [2] in Angola; Botswana; Namibia; Zambia and Zimbabwe. It is a common species but the population varies with the fluctuations in the flooding of the river systems. [1]
This species inhabits rocky areas of streams as well as large soft-bottomed lagoons in floodplains. It feeds mostly on algae, aufwuchs and detritus. [2] It is found over quieter rocky substrates and generally avoids rocky rapids. Its prefers the main channel of the rivers and has been recorded throughout the floodplain system It is a shoaling species which breeds in summer, most likely in flooded marginal habitats. [1]
This species can reach a length of 40 centimetres (16 in) SL. The maximum recorded weight of this species is 2.5 kilograms (5.5 lb). [2] It is greenish or silvery grey in colour with parallel lines along the body formed by the dark bases to the scales, it also has blackish membranes on the fins. The fleshy outer lips are covered in papillae with the inner edges being horny with sharper edges. The dorsal fin has four spines and 9-11 soft rays, while the anal fin has three spines and five soft rays. [3]
L. lunatus is important to local artisanal fisheries. [2] The species' population in the Upper Zambezi has declined probably as a result of overexploitation by fisheries catching the fish on their spawning runs. In addition, fish weirs set across the waters draining from floodplains catch large numbers of young fish returning to the rivers as the flood waters recede. [1]
The bludger, also known as the bludger trevally, nakedbreast trevally or Bleeker's jackfish, is a widespread species of large marine fish in the jack family, Carangidae. The bludger inhabits the tropical and subtropical regions of the Indo-west Pacific Ocean, distributed from South Africa in the west to Japan and New Caledonia in the east. It is a large fish, growing to a maximum recorded length of 90 cm, and is very similar to the yellowspotted trevally, Carangoides fulvoguttatus, but can be separated by the complete absence of breast scales and a number of other anatomical features. The species inhabits moderately deep offshore coral and rocky reefs, where it preys on small crustaceans and fish. The reproductive biology of the species is poorly known, but it appears to move to more tropical waters to spawn. The bludger is of intermediate importance to fisheries throughout its range, taken by hook and line and various netting methods. It is of some value to anglers also, considered a good gamefish, but generally regarded as poor eating due to its soft oily flesh, which is used as bait by many anglers. The name ‘bludger’ is said to either refer to the blunt head of the species, or the destination of the fish when caught by professional fishermen who treat the fish as discard.
Epinephelus albomarginatus, the white-edged grouper, white-edged rockcod or captain fine, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the southwestern Indian Ocean and it is associated with coral reefs. It is a target species for commercial and recreational fisheries.
The red grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the western Atlantic Ocean.
The Malabar trevally, also known as the Malabar jack, Malabar kingfish or nakedshield kingfish, is a species of large inshore marine fish of the jack family, Carangidae. It is distributed throughout the Indian and west Pacific Oceans from South Africa in the west to Japan and Australia in the east, inhabiting reefs and sandy bays on the continental shelf. The Malabar trevally is similar to many of the other species in the genus Carangoides, with the number of gill rakers and the grey-brown colour of the tongue being the diagnostic features. The Malabar trevally is a predator, taking a variety of small fish, cephalopods and crustaceans. The species is of minor economic importance throughout its range, caught by a variety of net and handline methods.
The longfin trevally, also known as the longfin kingfish, longfin cavalla or armed trevally, is a species of inshore marine fish in the jack family, Carangidae. The species is common in tropical to subtropical waters of the Indo-Pacific, ranging from South Africa in the west to Japan in the east, typically inhabiting inshore reefs and bays. The species is easily distinguished by its elongate dorsal and anal fin lobes and filamentous dorsal rays, as well as its scaleless breast. Longfin trevally are pelagic predators, taking a variety of small fish, cephalopods and crustaceans, and reach sexual maturity at around 21 cm. The species has a maximum known length of 57 cm and weight of 3.5 kg. The longfin trevally has a very complex taxonomic history which is closely intertwined with another currently valid species, Carangoides ciliarius, which may yet prove to be synonymous. Longfin trevally are of minor importance to fisheries throughout their range and are considered good table fish, and are occasionally taken by anglers.
The blue trevally, also known as the banded trevally, barred trevally, Ferdau's trevally or Forskaal's jackfish, is a common, widespread species of pelagic marine fish classified in the jack family, Carangidae. The blue trevally is distributed throughout the tropical and subtropical waters of the Indo-Pacific and central Pacific regions, ranging from South Africa in the west to Hawaii in the east. It is a moderately large fish, growing to a recorded maximum length of 70 cm, with the number of rays in the second dorsal fin and the colouring serving as diagnostic features of the species. The species inhabits waters to depths of 60 m, generally inhabiting reefs, beaches, lagoons, and areas with sandy substrates. It is a predatory fish, taking other fish, prawns, crabs, and molluscs, and very little is known of the species' reproductive biology. The blue trevally is of varying importance to fisheries throughout its range, with some regions having high catches of the fish. It is considered to be a gamefish, and is sought after for its excellent eating qualities.
The yellowspotted trevally, also known as the yellowspotted kingfish, goldspotted trevally or tarrum, is a widespread species of large inshore marine fish in the jack family Carangidae. The yellowspotted trevally inhabits the tropical and subtropical waters of the western Indo-Pacific region, from South Africa in the west to Japan and Australia in the east. The species is known to grow to a maximum length of at least 1.2 m, and is distinguished by gill raker and fin morphology, as well as the distinctive golden spots which give the fish its name. The yellowspotted trevally generally prefers inshore rocky and coral reefs, but is occasionally found over deep offshore sand banks to a depth of 100 m. It is a predatory fish, taking fish, cephalopods, and crustaceans, and shows diet partitioning with other trevallies in studies conducted in Australian waters. Reproduction is poorly studied, although observational evidence suggests spawning occurs in aggregations, probably during summer in South Africa. It is generally of minor importance to commercial fisheries throughout its range, but is considered an excellent sportfish by anglers and spearfishermen, and a good table fish.
The giant African threadfin is a species of ray-finned fish from the threadfin family Polynemidae. It is found in the eastern Atlantic Ocean off the west coast of Africa.
