Abstract

Using a traditional, commercial, crustacean bottom trawl net we collected fish samples from the southern Aegean Sea, from Dec 2009 to Nov 2010, at depths of 30–225 m. We collected a total of 35 428 specimens representing 50 families and 103 species: Argentina sphyraena Linnaeus, 1758; Arnoglossus laterna (Walbaum, 1792); Arnoglossus rueppelii (Cocco, 1844); Arnoglossus thori Kyle, 1913; Belone belone (Linnaeus, 1761); Belone svetovidovi Collette et Parin, 1970; Blennius ocellaris Linnaeus, 1758; Boops boops (Linnaeus, 1758); Bothus podas (Delaroche, 1809); Buglossidium luteum (Risso, 1810); Callionymus lyra Linnaeus, 1758; Callionymus risso Lesueur, 1814; Capros aper (Linnaeus, 1758); Cepola macrophthalma (Linnaeus, 1758); Chelidonichthys cuculus (Linnaeus, 1758); Chelidonichthys lucerne (Linnaeus, 1758); Chlorophthalmus agassizi Bonaparte, 1840; Chromis chromis (Linnaeus, 1758); Citharus linguatula (Linnaeus, 1758); Coelorinchus caelorhincus (Risso, 1810); Conger conger (Linnaeus, 1758); Coris julis (Linnaeus, 1758); Dentex dentex (Linnaeus, 1758); Diplodus annularis (Linnaeus, 1758); Diplodus sargus sargus (Linnaeus, 1758); Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817); Echelus myrus (Linnaeus, 1758); Equulites klunzingeri (Steindachner, 1898); Eutrigla gurnardus (Linnaeus, 1758); Fistularia commersonii Rüppell, 1838; Gadiculus argenteus Guichenot, 1850; Glossanodon leioglossus (Valenciennes, 1848); Gobius cruentatus Gmelin, 1789; Gobius niger Linnaeus, 1758; Helicolenus dactylopterus (Delaroche, 1809); Hoplostethus mediterraneus Cuvier, 1829; Labrus merula Linnaeus, 1758; Labrus viridis Linnaeus, 1758; Lampanyctus crocodilus (Risso, 1810); Lepidorhombus boscii (Risso, 1810); Lepidorhombus whiffiagonis (Walbaum, 1792); Lepidotrigla cavillone (Lacepède, 1801); Lepidotrigla dieuzeidei Blanc et Hureau, 1973; Lesueurigobius friesii (Malm, 1874); Lithognathus mormyrus (Linnaeus, 1758); Liza ramada (Risso, 1827); Lophius budegassa Spinola, 1807; Lophius piscatorius Linnaeus, 1758; Macroramphosus scolopax (Linnaeus, 1758); Merluccius merluccius (Linnaeus, 1758); Mullus barbatus barbatus Linnaeus, 1758; Mullus surmuletus Linnaeus, 1758; Mustelus mustelus (Linnaeus, 1758); Mustelus punctulatus Risso, 1827; Nemipterus randalli Russell, 1986; Oblada melanura (Linnaeus, 1758); Pagellus acarne (Risso, 1827); Pagellus bogaraveo (Brünnich, 1768); Pagellus erythrinus (Linnaeus, 1758); Parablennius tentacularis (Brünnich, 1768); Peristedion cataphractum (Linnaeus, 1758); Pomadasys incisus (Bowdich, 1825); Pomatoschistus minutus (Pallas, 1770); Raja miraletus Linnaeus, 1758; Raja radula Delaroche, 1809; Salaria pavo (Risso, 1810); Saurida undosquamis (Richardson, 1848); Sciaena umbra Linnaeus, 1758; Scomber japonicas Houttuyn, 1782; Scophthalmus rhombus (Linnaeus, 1758); Scorpaena notata Rafinesque, 1810; Scorpaena porcus Linnaeus, 1758; Scorpaena scrofa Linnaeus, 1758; Scyliorhinus canicula (Linnaeus, 1758); Scyliorhinus stellaris (Linnaeus, 1758); Serranus cabrilla (Linnaeus, 1758); Serranus hepatus (Linnaeus, 1758); Serranus scriba (Linnaeus, 1758); Solea solea (Linnaeus, 1758); Sphyraena chrysotaenia Klunzinger, 1884; Spicara maena (Linnaeus, 1758); Spondyliosoma cantharus (Linnaeus, 1758); Squalus blainvillei (Risso, 1827); Symphodus cinereus (Bonnaterre, 1788); Symphodus doderleini Jordan, 1890; Symphodus mediterraneus (Linnaeus, 1758); Symphodus melanocercus (Risso, 1810); Symphodus ocellatus (Linnaeus, 1758); Symphodus rostratus (Bloch, 1791); Symphodus tinca (Linnaeus, 1758); Syngnathus acus Linnaeus, 1758; Torpedo marmorata Risso, 1810; Torpedo nobiliana Bonaparte, 1835; Trachinus draco Linnaeus, 1758; Trachurus mediterraneus (Steindachner, 1868); Trachurus picturatus (Bowdich, 1825); Trachurus trachurus (Linnaeus, 1758); Trigla lyra Linnaeus, 1758; Trigloporus lastoviza (Bonnaterre, 1788); Upeneus moluccensis (Bleeker, 1855); Upeneus pori Ben-Tuvia et Golani, 1989; Uranoscopus scaber Linnaeus, 1758; Zeus faber Linnaeus, 1758. We estimated weight–length relations for the fishes collected. Values of the allometric coefficient (b) ranged from 2.1729 for Cepola macrophthalma to 3.6372 for Equulites klunzingeri. All relations were highly significant (P < 0.001), with the majority (94.17% of 103 species) r2 values being greater than 0.9. Four species evidenced isometric growth, 50 species showed positive allometry, and 49 species have negative allometry. Seven species studied were Lessepsian migrants.
