Pachymetopon blochii, the hottentot seabream or hottentot, is a species of sea bream in the family Sparidae, native to the southwestern coast of Africa.
Pachymetopon blochii has a bronzy grey color, with darker fins. The small mouth contains five rows of incisors in both upper and lower jaw, but no molars. [2] Adults are commonly around 25 cm in length at the age of maturity, but may reach up to 54 cm, with a maximum recorded weight of 2.67 kg. [1]
The species occurs in the southeastern Atlantic, from Angola to Cape Agulhas at the southern tip of South Africa. [3] Vagrants have been recorded as far east as the mouth of the Tsitsikamma River. [1]
Pachymetopon blochii inhabits kelp beds on shallow rocky reefs, as well as blinders, subtidal reefs and offshore pinnacles in deeper waters (up to 55 m). Juveniles are restricted to the kelp beds. [1]
The species is a generalist and feeds on seaweeds, algae, crustaceans, worms, molluscs, sea urchins, and occasionally small fish. It may spawn all year round, with peaks in summer and winter. [1] Individuals generally live to an age of about 12 years, [2] but may exceptionally reach an age of up to 21 years. Generation length is about 9 years. [1]
Pachymetopon blochii is a frequent host of the parasitic isopod Anilocra capensis . [4]
Pachymetopon blochii is an important species in a variety of smaller-scale fisheries (artisanal linefishery, recreational shore and ski-boat fishery) and occurs as bycatch in gill-net fishery. However, it appears not to be exploited to an extent that is damaging stocks, and is common in a number of protected areas in its range. It is therefore classified as Least Concern by the IUCN. [1]
The Cape lobster, Homarinus capensis, is a species of small lobster that lives off the coast of South Africa, from Dassen Island to Haga Haga. Only a few dozen specimens are known, mostly regurgitated by reef-dwelling fish. It lives in rocky reefs, and is thought to lay large eggs that have a short larval phase, or that hatch directly as a juvenile. The species grows to a total length of 10 cm (3.9 in), and resembles a small European or American lobster; it was previously included in the same genus, Homarus, although it is not very closely related to those species, and is now considered to form a separate, monotypic genus – Homarinus. Its closest relatives are the genera Thymops and Thymopides.
The California sheephead is a species of wrasse native to the eastern Pacific Ocean. Its range is from Monterey Bay, California, to the Gulf of California, Mexico. It can live for up to 20 years in favorable conditions and can reach a size of up to 91 cm (3 ft) and a weight of 16 kg (35 lb). It is carnivorous, living in rocky reef and kelp bed habitats, feeding primarily on sea urchins, molluscs, and crustaceans.
The redfingers is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only off the coasts of Namibia and South Africa, in rock pools and from shallow depths to 120 m, on rocky reef areas. Its length is up to 30 cm.
The Japanese bullhead shark is a species of bullhead shark in the family Heterodontidae found in the northwestern Pacific Ocean off the coasts of Japan, Korea, and China. This benthic shark occurs at depths of 6–37 m (20–121 ft) over rocky bottoms or kelp beds. Measuring up to 1.2 m (3.9 ft) long, it can be identified by its short, blunt head, two high dorsal fins with anterior spines, and pattern of irregularly shaped, vertical brown bands and stripes. The Japanese bullhead shark is a docile, slow-swimming species that feeds mainly on shelled invertebrates and small bony fishes. Reproduction is oviparous, with females laying spiral-flanged eggs in communal "nests". This species is of little interest to fisheries.
The pyjama shark or striped catshark is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. This abundant, bottom-dwelling species can be found from the intertidal zone to a depth of around 100 m (330 ft), particularly over rocky reefs and kelp beds. With a series of thick, parallel, dark stripes running along its stout body, the pyjama shark has an unmistakable appearance. It is additionally characterized by a short head and snout with a pair of slender barbels that do not reach the mouth, and two dorsal fins that are placed far back on the body. It can grow up to a length of 1.1 m (3.6 ft) long.
The leopard catshark is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. Abundant in inshore waters under 20 m (66 ft) deep, this bottom-dweller favors rocky reefs, kelp beds, and sandy flats. Growing to a length of 84 cm (33 in), the leopard catshark has a stout body with two dorsal fins placed well back, and a short head and tail. It is extremely variable in color and pattern, with individuals ranging from almost white to black and covered by diverse patterns of black spots, blotches, rosettes, and/or lines. The color pattern changes with age and some forms seem to be location-specific, suggesting the presence of multiple distinct, local populations. In the past, some of the more distinct color forms have been described as different species.
The puffadder shyshark, also known as the Happy Eddie, is a species of catshark, belonging to the family Scyliorhinidae, endemic to the temperate waters off the coast of South Africa. This common shark is found on or near the bottom in sandy or rocky habitats, from the intertidal zone to a depth of 130 m (430 ft). Typically reaching 60 cm (24 in) in length, the puffadder shyshark has a slender, flattened body and head. It is strikingly patterned with a series of dark-edged, bright orange "saddles" and numerous small white spots over its back. The Natal shyshark, formally described in 2006, was once considered to be an alternate form of the puffadder shyshark.
The yellowspotted catshark is a rare catshark of the family Scyliorhinidae. It is found in the southeast Atlantic, from Lüderitz, Namibia to central Natal, South Africa, between latitudes 0° and 37° S. It can grow up to a length of about 1.22 metres. The reproduction of this catshark is oviparous.
The Cape triplefin, Cremnochorites capensis, is a triplefin blenny of the family Tripterygiidae and only member of the genus Cremnochorites, found in the western Indian Ocean and southeast Atlantic, from Sodwana Bay to False Bay in South Africa. It reaches a maximum length of 8 centimetres (3.1 in). It is found below the low tide mark down to 30 metres (98 ft) on rocky reefs.
The Cape elephantfish, josef, or St Joseph shark is a species of fish in the family Callorhinchidae.
Chorisochismus dentex, the rocksucker or giant clingfish, is a species of clingfish found along the coast of southern Africa from Namibia to northern Natal, South Africa. It inhabits the intertidal and subtidal zones in shallow reefs and rock pools. This species is the only known member of its genus.
The Cape gurnard is a species of marine ray-finned fishes belonging to the family Triglidae, the gurnards and sea robins. This species is found in the southeastern Atlantic Ocean and the southwestern Indian Ocean. This species is of commercial importance as a food fish.
Anilocra capensis is a species of parasitic isopod in the family Cymothoidae. It is endemic to southern Africa. The species preferentially attaches itself to the hottentot seabream.
The De Hoop Marine Protected Area lies between Arniston and the mouth of the Breede River on the south coast of South Africa adjacent to the De Hoop Nature Reserve. The MPA is 51 kilometres long, and extends 5 nautical miles to sea. The whole MPA is a restricted area and is part of the migratory route and calving area for Southern right whales. The area protects habitats for several economically important inshore reef fish species, and ensures the retention of marine biomass in this part of the coast. The limestone coastline is includes archaeological sites and middens that date back centuries. The MPA is close to the Breede River estuary and, provides protection for species like cob that breed in the estuary and then return to the ocean.
The Helderberg Marine Protected Area is a small marine conservation area on the north-eastern side of False Bay in the Western Cape province of South Africa, It lies between the mouths of the Lourens River in the Strand, and the Eerste River in Macassar.

It is on the coast of the Tsitsikamma National Park, and is one of the oldest MPAs in the country. The MPA provides protection for marine habitat and wildlife, including birds and threatened and endangered fish species.
