Kyphosus cinerascens is a species of marine ray-finned fish. It is a sea chub from the family Kyphosidae. [2] [3] Kyphosus Cinerascens has 11 dorsal fins and 12 anal fins. [4] Kyphosus cinerascens are widely distributed in the Indo-Pacific region. [4] The Kyphosus cinerascens has a strict diet on phaeophytes, chlorophytes, and rhodophytes, making them herbivores. [5]

Description

An adult topsail sea chub grows up to 45 cm long and has a blue/grey, brown or black coloring. [6] They are a pale fish with dark lines that separate the rows of scales. [6]

Distribution and habitat

The species of sea chub occurs around the Indo-central Pacific and Atlantic Ocean; along several locations near the Greater Caribbean; and some areas in Brazil. [6] The sea chub is regularly found taking residence in areas of aggregations over hard algal coated bottoms of exposed, surf-swept outer reef flats, lagoons, and seaward reefs. They are commonly seen occupying depths of 24–45 m near these rocky areas. [7] Their habitats are usually seen within the Equatorial, Tropical, and Subtropical climate zones.

Diet

The sea chubs are herbivores that primarily eat phaeophytes, chlorophytes, and rhodophytes. [5]

Behavior

Sea chubs are typically more active during the day where they can be found swimming in schools of 10 or more along the reef, although at night only lone individuals can be found swimming near the sea floor. [8] They are usually found feeding on algae found on rocks and even free-floating algae particles. [8] Meanwhile, their nocturnal habits and behaviors are still unknown despite their common solitary observations.

Conservation Significance

There are five known species of Kyphosus found in Hawai'i, with four being from the drab genus Kyphosus and the other being the Sectator ocyurus. [9] However due to the species of Kyphosus choosing algae as their main source of food, the State of Hawai'i was advised to put this fish species under protective care to help restore the control of nearby algae. [9]

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.

<span class="mw-page-title-main">Hallucinogenic fish</span> Fish which can produce hallucinogenic effects when eaten

Several species of fish are claimed to produce hallucinogenic effects when consumed. For example, Sarpa salpa, a species of sea bream, is commonly claimed to be hallucinogenic. These widely distributed coastal fish are normally found in the Mediterranean and around Spain, and along the west and south coasts of Africa. Occasionally they are found in British waters. They may induce hallucinogenic effects similar to LSD if eaten. However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations lasting for several days. The likelihood of hallucinations depends on the season. Sarpa salpa is known as "the fish that makes dreams" in Arabic.
