Pseudopercis chilensis (Valenciennes, 1833)

Pinguipes chilensis, commonly known as the Chilean sandperch, is a species of ray-finned fish in the family Pinguipedidae. It is found in the southeastern Pacific Ocean off the coasts of Peru and Chile. [1] [2]

Description

P. chilensis can grow to a maximum length of 51 cm (20 in). The dorsal fin has six spines and twenty-eight soft rays, and the anal fin has a single spine and twenty-five soft rays. [2] A specimen caught by Charles Darwin during the Beagle voyage was described as being more elongated than Pinguipes brasilianus , being about six and a half times as long as the body is deep and as having two longitudinal rows of ill-defined spots on the flanks and a larger, dark-coloured, round spot at the base of the caudal fin. [3]

Distribution and habitat

P. chilensis is found in the southeastern Pacific Ocean. Its range extends from Tumbes in northern Peru, southwards to the Magallanes Region of southern Chile. It is found on muddy bottoms as well as on rocks and sand, to depths of 100 m (330 ft). [2] It is also present in the kelp forest alongside other carnivorous fish such as the Peruvian morwong (Cheilodactylus variegatus), the sea chub ( Graus nigra ) and the Cape redfish (Sebastes capensis). [4]

Ecology

P. chilensis is a generalist predator, its diet consisting mainly of crustaceans, with smaller quantities of fish and polycheate worms; less often eaten are molluscs, brittle stars, sea urchins, proboscis worms, peanut worms, spoon worms and tunicates. Small fish (less than 30 cm (12 in) long) fed largely of the amphipod Ampelisca araucana while medium size fish mostly took mysids such as Neomysis sp. The largest fish (over 40 cm (16 in) long) mostly preyed on other species of fish, worms, molluscs and sea urchins. The diet also varies according to the time of year and the seasonal availability of prey species, with more fish being taken in the autumn. [5] This fish is oviparous, with spawning taking place in the spring. [6]

Sandperch Family of fishes

The sandperches are a family, Pinguipedidae, of fishes in the percomorph order Trachiniformes. Sandperches are benthic fish which normally occur over sand or rubble substrates in shallow seas. They are found off the coasts of South America, South Africa and in the Indo-Pacific as far east as Japan. The family contains a few species which are used by humans for food.

Horn shark Species of shark

The horn shark is a species of bullhead shark, in the family Heterodontidae. It is endemic to the coastal waters off the western coast of North America, from California to the Gulf of California. Young sharks are segregated spatially from the adults, with the former preferring deeper sandy flats and the latter preferring shallower rocky reefs or algal beds. A small species typically measuring 1 m (3.3 ft) in length, the horn shark can be recognized by a short, blunt head with ridges over its eyes, two high dorsal fins with large spines, and a brown or gray coloration with many small dark spots.

Grey triggerfish Species of fish

The grey triggerfish or gray triggerfish is a ray-finned fish in the triggerfish family. The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa.

<i>Lophius americanus</i> Species of fish

Lophius americanus is a goosefish in the family Lophiidae, also called all-mouth, American anglerfish, bellows-fish, devil-fish, headfish, molligut, satchel-mouth, or wide-gape. It is native to the eastern coast of North America.

Longnose trevally Species of fish

The longnose trevally, also known as the tea-leaf trevally, club-nosed trevally, grunting trevally or dusky trevally, is a species of inshore marine fish in the jack family, Carangidae. The species is distributed throughout the tropical and subtropical waters of the Indian and west Pacific Oceans from South Africa to New Zealand and Japan, inhabiting coastal waters, especially reefs, to a depth of 90 m. The longnose trevally is distinguished from similar species by a combination of a scaleless breast and the number of gill rakers and fin rays. It is a moderately large fish, growing to a maximum known length of 72 cm and 4.35 kg. The longnose trevally is a predatory fish, consuming small fish, crustaceans and molluscs. The species is of minor commercial importance throughout its range, and is considered to be a good table fish.

Blue trevally Species of fish

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.
