Comprehensive Description ( Anglèis )

fornì da Smithsonian Contributions to Zoology
Diaphus metopoclampus

This questionably bipolar, temperate-semisubtropical species (Backus et al., 1977) is found in the Atlantic Ocean mainly south of 30°S (Krefft, 1974) and north of 20°N (Nafpaktitis, 1968). Although everywhere rare, it seems to be most abundant in the slope water areas (Nafpaktitis et al., 1977). This is a fairly large myctophid, reaching a size of about 80 mm; maximum size in the Ocean Acre collections is 79 mm. The species is “uncommon” in the study area; a total of 125 specimens was caught, 70 were taken during the paired seasonal cruises. Discrete-depth samples account for 51 fish, of which 47 are from noncrepuscular tows (Table 23).

DEVELOPMENTAL STAGES.—Postlarvae were 6–8 mm, juveniles 9–35 mm, subadult females 71–79 mm, and adult males 62–75 mm SL. No subadult males or adult females were taken. With the possible exception of size, there is no sexual dimorphism (Nafpaktitis, 1968). Although no adult females were caught, a 74 mm female taken in August had a few large ova (0.2–0.3 mm) and slightly enlarged ovaries. Gravid females 55–60 mm have been taken in the Gulf of Mexico (Nafpaktitis et al., 1977). Grey (1955) reported that a 73 mm female taken near Bermuda in August 1948 contained eggs in cleavage. This report has not been confirmed.

REPRODUCTIVE CYCLE AND SEASONAL ABUNDANCE.—The life cycle of D. metopoclampus in the Bermuda area apparently is complex and, like that of its congener D. rafinesquii, may involve migrations into and possibly out of the area. It cannot be determined whether D. metopoclampus spawns in the area. Although the life span cannot be determined from the present data, it probably is at least two years. The parent population spawns over a relatively short time, probably in spring or summer.

All specimens caught were either 6–35 mm or 62–79 mm. The want of intermediate sizes in the Ocean Acre collections almost surely reflects their absence in the study area rather than a sampling bias. If intermediates were present, at least one specimen would have been caught during the 14 cruises. The missing sizes have been taken in midwater trawls fished in the slope water (Krueger et al., 1975; Jahn, 1976; personal observation) and in the Gulf of Mexico (Nafpaktitis et al., 1977). This means that large fish must migrate into the Bermuda area with some regularity to maintain their numbers. Small fish either migrate out of the area or die before they reach about 40 mm.

Small fish were mostly 9–12 mm in September to October, 13–17 mm in January to March, 20–26 mm in June, and 25–30 mm in July. Presumably those taken in June and July were 10–12 months old. It follows that large fish taken at those times were a year or more older than the small fish, and that the life span is at least two years.

The catch in September (one cruise only; none were taken during other September cruises) was almost exclusively 9–12 mm juveniles. The smallest of these fish probably were recently transformed juveniles, which suggests that spawning either takes place in the study area or in close proximity to it. The relatively large number of small fish taken in September (although not in discrete-depth samples) may indicate a peak in spawning activity at or just before that time.

Abundance was greatest in winter (Table 47). In late spring it was only about one-third as great as in winter. No estimate of abundance could be made for late summer because no specimens were caught in noncrepuscular discrete-depth samples. If spawning occurred in spring or summer, abundance would be greater in late summer than in winter.

VERTICAL DISTRIBUTION.—Depth range by day in winter is 501–850 m with no apparent concentration at any depth, and in late spring 601–750 m with a maximum abundance at 601–700 m. By night, depth range is 401–800 m in winter with a maximum at 651–750 m, and in late spring 351–400 m (1 specimen) and 551–600 m (3 specimens) (Table 47). Three postlarvae were caught at 45 m near dawn in late summer. Gibbs et al. (1971) noted that an 18 mm fish was taken at 201–250 m by night in April.

These data show that small juveniles (13–19 mm) do not migrate regularly, and that at least some large fish over 60 mm remain at day depths during the night (Table 47).

Punktkopf-Laternenfisch ( Alman )

fornì da wikipedia DE

Der Punktkopf-Laternenfisch (Diaphus metopoclampus) ist ein kleiner Tiefseefisch, der fast weltweit in tropischen und gemäßigten Meeren vorkommt. Er fehlt lediglich im Indischen Ozean östlich von 70° Geographischer Länge und im östlichen Pazifik. Er kommt auch an der Atlantikküste Europas und im Mittelmeer vor.

Merkmale

Der Punktkopf-Laternenfisch wird 6,5 bis 7,7 cm lang und ist mit 4,8 cm Länge geschlechtsreif. Er hat einen dicken Kopf mit großen Augen und tiefer Maulspalte und einen kurzen, gedrungenen Körper, der seitlich leicht abgeflacht ist und nach hinten spindelförmig zuläuft. Charakteristisches Merkmal der Art sind zwei scheinwerferähnliche, große, fast rechteckige Leuchtorgane, die sich am Vorderkopf zwischen den Augen befinden und sich median berühren. Ausläufer dieser Leuchtorgane erstrecken sich entlang des Unterrandes der Augen. Weitere Leuchtorgane finden sich auf den Flanken unterhalb der Seitenlinie, am Bauch und am Schwanzflossenstiel.

Lebensweise

Der Punktkopf-Laternenfisch lebt ozeanisch und mesopelagisch tagsüber in Tiefen von 375 bis 850 Metern (bis 1085 Meter im östlichen Ionischen Meer). Er unternimmt zur Nahrungssuche Vertikalwanderungen und steigt in der Nacht bis auf 90 Meter Wassertiefe auf.

Spothead lantern fish ( Anglèis )

fornì da wikipedia EN

The spothead lantern fish (Diaphus metopoclampus), also called the bluntnose lanternfish,[3] is a species of fish in the family Myctophidae (lanternfish).[4][5]

Its specific name is from Ancient Greek μέτωπον (metōpon, "forehead") and λαμπάς (lampas, "lantern").[6]

Description

The spothead lantern fish is black and pink in colour, with a maximum length of 7.5 cm (3.0 in).[7][8] It has a deep and short head and prominent photophores in its head.[9]

Habitat

Diaphus metopoclampus is bathypelagic and non-migratory, living at depths of 90–1,085 m (295–3,560 ft) in non-polar seas worldwide, typically on the continental slope.[10][7]

Behaviour

The spothead lantern fish attains sexual maturity at 4.8 cm (1.9 in) in length; it spawns in the spring and summer.[11]

Diaphus metopoclampus ( Italian )

fornì da wikipedia IT

Il muso lucente (Diaphus metopoclampus) è un pesce abissale della famiglia Myctophidae.

Distribuzione e habitat

È presente nella fascia subtropicale dell'Oceano Atlantico e nel mar Mediterraneo. Nei mari italiani sembra rara, segnalata solo nel mar Tirreno, in Sardegna ed anche nello stretto di Messina, dove spiaggia di rado, in primavera ed in autunno.

Vive almeno fino ad 800 m di profondità ed ha abitudini pelagiche.

Descrizione

Anche se, come in tutti i pesci lanterna per una corretta identificazione si devono osservare i caratteri dei fotofori, questa specie appare caratteristica per la grande testa e la sagoma tozza. Sul muso è presente un grande fotoforo a forma di mezzaluna, formato dai Dn e dai Vn fusi assieme, che lo rende assolutamente inconfondibile. Questo organo luminoso si estende anche sotto il grande occhio. Non ci sono ghiandole luminose sul peduncolo caudale. I fotofori sono divisi in due parti uguali da un setto nero.

Il colore è blu-nero con riflessi metallici, gli occhi sono verdi ed il grande fotoforo frontale è biancastro. Può raggiungere i 10 cm.

Alimentazione

Si ciba di piccoli crostacei planctonici.

Pesca

Casuale con reti a strascico pelagiche. Non viene venduta sui mercati.
