Caesio varilineata ( Anglèis )

fornì da wikipedia EN

Caesio varilineata, the variable-lined fusilier or thin-lined fusilier, is a species of pelagic marine ray-finned fish, a fusilier belonging to the family Caesionidae. It is found in the Indo-Pacific region.

Taxonomy

Caesio varilineata was first formally described in 1987 by the American ichthyologist Kent E. Carpenter with the type locality given as the Persian Gulf.[2] Carpenter placed it in the subgenus Caesio. The specific name is a combination of vari-, meaning “various” and lineata which means “lined”, a reference to the variable number of horizontal, golden stripes on the flanks.[3]

Description

Caesio varilineata is a small to medium-sized fish which grows to about 40 cm (16 in) long.[4] The eyes are large, the mouth is small and terminal and is protrusible, being able to be extended forward to swallow food. The body is fusiform or spindle-shaped. The caudal fin is deeply forked.[5] The dorsal fin has 10 spines and 14-16 soft rays while the anal fin contains 3 spines and 11-13 soft rays. This species attains a maximum total length of 40 cm (16 in).[4] The body colouration is silver green-blue with from 2 to 6 yellow longitudinal lines which intensity and width are variable. The external part of the lobes from the caudal fin are lined with black.[5]

Distribution & habitat

Caesio varilineata is only found in the Indian Ocean from western Indonesia to the eastern coast of Africa, Red Sea and Persian Gulf included. It lives in the open water close to reef and the external reefs.[4] This species was recently reported from the Mediterranean Sea off Alexandria, Egypt, a likely entry via the Suez Canal.[6] As there are no coral reefs in the Mediterranean these fusiliers have probably adapted to use rock reefs covered by Anthozoa.[7]

Biology

Caesio varilineata has a diet consisting of zooplankton which it feeds on in aggregations in the middle of the water column. It frequently joins mixed species schools with other species of fusiliers. It is an oviparous fish, laying a large number of small pelagic eggs.[4]

Fisheries

Caesio varilineata is moderately important to some coastal fisheries within its range and of minor importance in others. It is caught with gillnets, handlines and traps and is sold as fresh fish. It is a common item in fish markets in East Africa and in Sri Lanka, although only infrequently reported from markets in Oman, maybe as bycatch. In the Maldives and Laccadives, the juveniles are caught to be used as bait in the tuna fishery. This species is vulnerable to overexploitation and is regarded as being overfished in the Persian Gulf.[1] The records from the Mediterranean came from fish markets in Alexandria.[7]

Caesio varilineata ( Fransèis )

fornì da wikipedia FR

Caesio varilineata, ou communément nommé fusilier à bandes variées, est une espèce de poissons osseux de la famille des Caesionidés.

Description

Le fusilier à bandes variées possède un corps fusiforme, allongé et légèrement compressé latéralement. L’œil est relativement grand, la nageoire caudale est fourchue et les deux lobes de cette dernière sont en pointe. Sa livrée est bleu-vert argenté avec des lignes jaunes dont le nombre (entre 2 et 6), l'intensité et l'épaisseur varient d'un individu à l'autre, les lobes de la nageoire caudale sont bordés de noir[1]. Sa taille maximale est de 40 cm[2].

Distribution et habitat

Caesio varilineata ne se rencontre que dans l'Océan Indien soit de l'ouest de l'Indonésie aux côtes orientales africaines, Mer Rouge et Golfe Persique inclus. Ils vivent en pleine eau à proximité des récifs et des pentes récifales externes[2].

Biologie

Ces fusiliers sont d'infatigables nageurs planctophages se nourrissant de zooplancton, ils sont de caractère grégaire et se mélangent volontiers à d'autres Caesionidés[3]. La nuit, ils se dispersent en petits groupes sur les récifs pour tenter de trouver un abri afin de se reposer.

Caesio varilineata ( Italian )

fornì da wikipedia IT

Caesio varilineata (Carpenter, 1987) è un pesce osseo marino appartenente alla famiglia Caesionidae.[2].

Distribuzione e habitat

C. varilineata è endemico delle fasce tropicali dell'oceano Indiano dall'Africa orientale e le Seychelles a Sumatra. È presente anche nel mar Rosso e nel golfo Persico. In seguito alla migrazione lessepsiana è penetrato nel mar Mediterraneo orientale dove si trova lungo le coste egiziane[3][4][5].

È un pesce pelagico costiero che forma banchi a mezz'acqua sopra le formazioni coralline. Lo si trova nelle lagune più profonde e lungo il bordo esterno delle barriere coralline. È più comune lungo le coste delle isole che sulle coste continentali[1][4].

È riportata una distribuzione batimetrica tra 2 e 25 metri[4].

Descrizione

C. varilineata ha corpo fusiforme e poco compresso ai lati, bocca abbastanza piccola e occhi grandi. La pinna dorsale è lunga, con 10 raggi spinosi e 15 molli; la pinna anale, più breve, ha 3 raggi spiniformi e 12 molli. La pinna caudale è profondamente forcuta e i lobi sono appuntiti. La colorazione è blu-verde su dorso e fianchi e biancastra nella regione ventrale; sui fianchi decorrono alcune (normalmente 6) strisce dorate longitudinali che scompaiono o si affievoliscono notevolmente dopo la morte dell'animale. Le punte dei lobi della pinna caudale sono nere e una piccola macchia nera è presente all'ascella delle pinne pettorali[3][4][5].

La taglia massima nota è di 40 cm[4].

Biologia

Comportamento

Forma banchi numerosi a mezz'acqua, talvolta con altre specie di Caesionidae[1][4][5].

Alimentazione

Si nutre di zooplancton[6].

Riproduzione

Produce numerose uova pelagiche di piccole dimensioni[4].

Pesca

Non è oggetto di pesca specifica ma costituisce un frequente bycatch di altre tecniche come lenze, reti da posta e nasse. È comunemente presente sui mercati ittici specie dell'Africa orientale e di Sri Lanka. I giovanili vengono usati come esca per i tonni nelle Maldive e nelle Laccadive[1][4].

Conservazione

Si tratta di una specie comune o abbondante in gran parte dell'areale ma si sono evidenziate alcune situazioni di rarefazione e di decrescita della taglia media in aree dove è sottoposto a sovrapesca come nella parte meridionale del golfo Persico e in Kenya. Un'altra possibile minaccia è costituita dalla degradazione dell'habitat corallino. È invece molto comune in aree dove non è sfruttato come il mar Rosso o l'Oman. La lista rossa IUCN la classifica come "a rischio minimo"[1].
