Biology ( anglais )

fourni par Fishbase
In the Red Sea, it is often found on patchy open reef areas. Feeds diurnally on fishes (64%, mostly pomacentrids) and crustaceans (36%). It is a monogamous species, the pair jointly defends a common territory of up to 62 square m (Ref. 6480). Major threats include overfishing, lack of management and habitat loss (Ref. 089707).

Cephalopholis hemistiktos, the yellowfin hind, is a species of marine ray-finned fish, a member of the family Serranidae, which also includes the anthias and sea basses. This species is found from the Red Sea to the Persian Gulf and the coast of Pakistan. A single specimen was filmed in 2009 in the Mediterranean Sea, off Malta.[2]

Habitat

This species is most commonly found in coral assemblages at depths slightly exceeding 50 metres, but can also be found in rocky regions. It may grow up to 35 centimetres in length.

Description

Adult displaying bright red colours

It has 9 spines and 14 soft rays on its dorsal fin,[3] and is deep red in colour. The margins of the fish’s pectoral fins are yellow, being its namesake. The mouth of the hind has four “canine” teeth, used to grip and seize prey

Cephalopholis hemistiktos ( italien )

fourni par wikipedia IT

Cephalopholis hemistiktos (Rüppell, 1830) è un pesce osseo marino appartenente alla famiglia Serranidae[2].

Distribuzione e habitat

Questa specie è endemica di un'area che comprende il mar Rosso, il golfo Persico e le coste del Pakistan[3][4].

É una specie legata alle barriere coralline, principalmente diffusa laddove le colonie di madrepore sono distanziate e non formano una copertura continua[1][3][4].

Si trova tra 4 e 55 metri di profondità, più comunemente fra 15 e 20[3].

Descrizione

Ha l'aspetto tipico delle cernie ma piuttosto allungato e slanciato. La mascella raggiunge e talvolta supera l'occhio. La livrea è decisamente variabile: la tinta di fondo è verdastra od oliva negli esemplari che vivono in acque superficiali mentre è rossa in quelli che stazionano più in profondità, queste colorazioni possono avre diverse screziature o essere disposte in fasce. il corpo e le pinne sono cosparsi di macchioline azzurre o più di rado bianche, che spesso mancano nella regione dorsale. Le pinne pettorali hanno la parte posteriore gialla[3][4].

La taglia massima è di 35 cm, quella comune di circa 23 cm[3]. Gli individui del mar Rosso sono sensibilmente più piccoli[1].

Biologia

Può vivere fino a 26 anni[3].

Comportamento

Diurno[3].

Alimentazione

Predatore. Si nutre di pesci (64% della dieta, prevalentemente della famiglia Pomacentridae) e crostacei. Caccia durante le ore del giorno[3][5].

Riproduzione

Forma coppie monogame che difendono un territorio ampio fino a 62 mq[1][3].

Pesca

Nel mar Rosso, dove raggiunge una taglia piccola, è oggetto solo occasionale di pesca mentre viene insidiato con più frequenza nel resto dell'areale anche se non esiste una pesca mirata a questa specie. Viene catturato con lenze, nasse e con il fucile subacqueo[1].

Conservazione

Si tratta di una specie abbondante, specie nel mar Rosso dove è la specie di cernia più comune. Le popolazioni più soggette a prelievo come quelle di Abu Dhabi mostrano segni di rarefazione. La degradazione dell'ambiente corallino è un'altra possibile minaccia. La lista rossa IUCN, comunque, la classifica come "a rischio minimo"[1].
