Fingerfisch ( Almanca )

wikipedia DE tarafından sağlandı

Der Fingerfisch (Polydactylus quadrifilis, Syn.: Polynemus quadrifilis) ist ein Meeresfisch aus der Familie der Fadenflosser.

Beschreibung

Merkmale

Der Fingerfisch wird maximal 2 Meter lang[1] und ist damit neben Eleutheronema tetradactylum[2] die größte Fadenflosserart. Etwa 32 Prozent der Standardlänge entfallen auf den Kopf, auf die Schwanzflosse etwa 37 Prozent. Die Brustflossen sind gelblich gefärbt. An jeder befinden sich 4 Fäden (bei den meisten anderen Fadenflossern sind es 5 bis 9 Fäden). Die erste Rückenflosse besteht aus 8 Hartstrahlen. Der dritte Hartstrahl ist der längste, der erste ist stark verkürzt. Erste und zweite Rückenflosse sind deutlich voneinander getrennt. Die Afterflosse und die zweite Rückenflosse sind groß und konkav. Erstere hat 3 Hartstrahlen und 11 Weichstrahlen, letztere einen Hartstrahl und 13 Weichstrahlen. Die homocerke Schwanzflosse ist groß und tief gegabelt. Die Flanken sind dunkelsilber, der Rücken ist dunkler gefärbt. Der Bauch ist weiß. Das Maul ist stark unterständig. Die großen Augen liegen weit vorne am Kopf.[3]

Lebensweise

Der Fingerfisch ist ein bodenbewohnender[1] Raubfisch. Er ernährt sich bevorzugt von Krebstieren und Fischen.[1][3] Mit den langen Flossenfäden kann er Nahrung am Grund aufspüren. Er ist ein guter und schneller Schwimmer.

Heimat und Lebensraum

Der Fingerfisch bewohnt die westafrikanischen Küstengebiete vom Senegal im Norden bis zum Kongo im Süden.[3] Außerdem ist er vor São Tomé und Príncipe zu finden. Gelegentlich hält er sich im Brackwasser auf. Er bevorzugt weichen, sandigen Untergrund.[1]

Bedeutung

Der Fingerfisch ist als Speisefisch in der kommerziellen Fischerei bedeutend,[3] auch unter Sportfischern ist er beliebt. Er gilt als nicht gefährdet.[1]

The pectoral fin has 12 or 13 unbranched rays and it measures 20 to 24% of the standard length of the fish, its tip not extended as far as the tip of pelvic fin. There are 4 pectoral filaments with the first being the shortest, the first three filaments extend past the origin of the pelvic fin but not as far as its tip. The fourth pectoral filament is the longest, being 27 to 39% of the standard length, reaches at least to the tip of the pelvic fin. The caudal fin is deeply forked and has lobes non-filamentous long lobes. There are 70*71 pored scales in the lateral line which is simple and runs from the upper end of the gill slit to the upper end of the lower lobe of the caudal fin. The head and upper flanks are silver with a blackish tint, paler on the lower flanks and white on the breast and belly. The snout is semi-transparent. The dorsal fins and caudal fin are pale with blackish rear margins. The pectoral fin is bright yellow and the pectoral filaments are white. The pelvic and anal fins are dusky with white on the front edge and at their bases.[3]

Habitat and biology

The giant African threadfin is found in shallow coastal waters where there are sandy and muddy bottoms and is occasionally recorded in brackish waters. It will enters estuaries and is rarely taken in fresh water but the largest individuals are only recorded from marine waters. This carnivorous fish east crustaceans and fishes.[2]

Fisheries

The giant African threadfin is a highly sought after species for commercial and sport fisheries.[3]

Species description

The giant African threadfin was first formally described by Georges Cuvier in Histoire naturelle des poissons. Tome troisième. Suite du Livre troisième. Des percoïdes à dorsale unique à sept rayons branchiaux et à dents en velours ou en cardes co-authored with Achille Valenciennes. The name Cuvier gave it was Polynemus quadrifilis and the type locality was given as Senegal.[4]
