Galjoen is the national fish of South Africa. Distribution and habitat The galjoen is indigenous to the coasts of southern Africa from Angola to South Africa, and is generally found around reefs at shallow depths around , often near the shore.

Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Marine Protected Areas Of South Africa
The marine protected areas of South Africa are in an area of coastline or ocean within the exclusive economic zone (EEZ) of the Republic of South Africa that is protected in terms of specific legislation for the benefit of the environment and the people who live in and use it. An MPA is a place where marine life can thrive under less pressure than unprotected areas. They are like underwater parks, and this healthy environment can benefit neighbouring areas. There are a total of 42 marine protected areas in the South African EEZ, after consolidation, with a total area of 15.5% of its Exclusive Economic Zone (EEZ). The target was to have 10% of the oceanic waters protected by 2020. All but one of the MPAs are in the exclusive economic zone off continental South Africa, and one is off the Prince Edward Islands in the Southern Ocean. Without the large Prince Edward Islands MPA, South Africa has 41 MPAs covering 5.4% of its continental EEZ. This achieves United Nations Sustainable D ...

Dichistiidae
''Dichistius'' is a genus of centrarchiform ray-finned fishes, the galjoen fishes, native to the Atlantic coast of southern Africa (''D. capensis'') and the Indian Ocean coast of southern Africa (''D. multifasciatus'').

South African Cuisine
South African cuisine reflects the diverse range of culinary traditions embodied by the various communities that inhabit the country. Among the indigenous peoples of South Africa, the Khoisan foraged over 300 species of edible food plants, such as the rooibos shrub legume, whose culinary value continues to exert a salient influence on South African cuisine. Subsequent encounters with Bantu peoples in South Africa, Bantu pastoralists facilitated the emergence of cultivated crops and domestic cattle, which supplemented traditional Khoisan techniques of meat preservation. In addition, Bantu-speaking communities forged an extensive repertoire of culinary ingredients and dishes, many of which are still consumed today in traditional settlements and urban entrepôts alike. History The San peoples were hunter-gatherers, who mostly depended on foods like tortoises, Crayfish as food, crayfish, coconuts and squash (plant), squash.

Game Fish
Game fish, sport fish or quarry refer to popular fish species pursued by recreational fishing, recreational fishers (typically angling, anglers), and can be freshwater fish, freshwater or saltwater fish. Game fish can be fish as food, eaten after being caught, preserved as taxidermy (though rare), or catch and release, released after capture. Some game fish are also targeted commercial fishing, commercially, particularly less bony species such as salmon and tuna. Specimens of game fish whose fish measurement, measurements (body length and standard weight in fish, weight) significantly exceed the species' average are sometimes known as trophy fish, as such captures are often presented as bragging rights among fishers. Examples The species of fish prized by anglers varies with geography and tradition. Some fish are sought for their value as seafood, food, while others are pursued for their fighting abilities, or for the difficulty of successfully enticing the fish to bite th ...

Commercial Fisheries
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world's fishe ...

South African Sustainable Seafood Initiative List
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).
