Background. Weight-length relationships of discarded species can de used for the estimation of discarded quantities per species, if the species length-frequency distribution is known. In this study, we present weight-length for 26 fish species discarded by commercial trawlers. Materials and Methods. We present weight -length relationships (W=a TL b ), for 26 discarded fish species, from samples caught...
Bluespotted cornetfish, Fistularia commersonii Rüppell, 1838 is a Lessepsian migrant, recorded for the first time in the Mediterranean in Israeli waters in 2000 and two years later off Rhodes Island, south-eastern Aegean Sea. The presently described case of e single specimen constitutes the first record of its northernmost appearance, caught with trammel-nets in the waters off Loutra Agias Paraskevis...
Two species previously unrecorded from the Aegean Sea, Nemichthys scolopaceus Richardson, 1848 and Benthocometes robustus (Goode et Bean, 1886), were captured during a bottom trawl off the Marmaris coasts (Turkey). These new records represent respectively the easternmost occurrence of N. scolopaceus and the second record of B. robustus from the eastern Mediterranean Basin.
Three fish species, Bregmaceros atlanticus Goode et Bean, 1886 (Bregmacerotidae), Echiodon dentatus (Cuvier, 1829) (Carapidae), and Nemichthys scolopaceus Richardson, 1848 (Nemichthyidae) were recorded in the Sığacık and Kuşadası Bays (Eastern Aegean Sea, Turkey). B. atlanticus and E. dentatus constitute new records for the Turkish waters and the Aegean Sea, respectively. The finding of Nemichthys...
In 2008, a specimen of a pignosed arrowtooth eel, Dysomma brevirostre (Facciolà, 1887), was caught by a bottom trawling operation at Sigacik Bay (Aegean Sea), Turkey. Total length (TL) and weight of the fish were 23.2 cm and 2.00 g, respectively. This study reports the first record of D. brevirostre from the Aegean Sea and logs a new species for the Turkish Ichthyofauna.
The first record of imperial blackfish, Schedophilus ovalis (Cuvier, 1833), in the Greek waters of the Aegean Sea is herewith documented. This record increases the knowledge on the richness of the Hellenic marine ichthyofauna and may suggest an expansion of the geographical distribution of the species from the southern Levantine waters to northern areas.
Background. Marine ichthyofauna of the Mediterranean Sea is represented by 712 species, 117 of which are deepwater fishes. During the last decade, this ichthyofauna has been considerably enriched, either by Suez Canal or Strait of Gibraltar migrations or simply by mariculture escapees. This study is intended to discussed morphology of one of such non-indigenous fish species and its distribution. Materials...
One specimen of the Cadenat’s rockfish, Scorpaena loppei Cadenat, 1943 (Scorpeanidae), was caught off Marmaris (eastern Aegean Sea, Turkey) on 27 December 2008 by bottom trawl net. The specimen was 56.15 mm total length. S. loppei is evidently rare in the Aegean Sea than it is in the western Mediterranean.
A second record of the small Indo-Pacific fish Tylerius spinosissimus (Tetraodontidae) (known as spiny blaasop) was documented at the beginning of 2009 in the waters of Rhodes Island (south-eastern Aegean Sea, Greece). The finding shows the putative establishment of a population of this alien fish in the Mediterranean with a centre the Dodecanese plateau.
Background. Even though Serranus cabrilla has been a by-catch species in trawling operations, it is now becoming an economically important fish species on the Turkish Coast of Aegean Sea, because of its low market price. For an efficient fisheries management of the stocks it is important to know important biological parameters of the commercially exploited species. Therefore the aim of this study...
A specimen of Facciola’s sorcerer, Facciolella oxyrhyncha (Bellotti, 1883), was caught for the first time in the central Aegean Sea, on January 2007 by a commercial bottom trawler at a depth of about 230 m on the muddy bottom of Southern Sigacik Bay, Aegean Sea, Turkey.
Background. Limited information is available on the reproductive biology of grey mullets mainly because it is very difficult to collect fully mature specimens. In the presently reported study the reproductive biology of two mugilid species, namely Liza saliens and Liza ramada, was studied in the Vistonis and Porto Lagos estuarine systems. Materials and methods. Gonadosomatic index (GSI) and standard...
