Summary Length–weight relationships for 47 coastal fish species from Gökceada Island in the northern Aegean Sea, Turkey are presented. Samples were caught in depths of <30 m by gill and trammel nets between March 2004 and February 2005. The most abundant families were Sparidae (30%), Centracanthidae (19.9%), Serranidae (7.14%), Scorpaenidae (6.59%) and Labridae (6.09%). Estimates for parameter b of the length–weight relationship (W = aLb) ranged between 2.08 and 3.73. The mean b‐value 3.03 ± 0.052 (SE) was not significantly different from 3. Significant differences between b‐values were found between sexes for Boops boops, Diplodus annularis, Mullus surmuletus, Pagellus acarne, Sarpa salpa, Spicara maena and Spicara smaris and between seasons for Diplodus annularis, Mullus surmuletus and Spicara maena.

“…Most published regressions of OL to SL (Wyllie Echeverria, 1987;Gamboa, 1991;Harvey et al, 2000;Waessle et al, 2003) or SL to W relationships (Harvey et al, 2000;Valle et al, 2003;İlkyaz et al, 2008;Mata et al, 2008) concern coastal or commercially important species. Very few data are available on mesopelagic and bathypelagic fishes.…”

SUMMARY: The length-weight relationships and the regressions between otolith size (length and width) and fish length of some mesopelagic and bathypelagic fishes living in the central Mediterranean Sea were provided. Images and morphological description of otoliths (sagittae) from 16 species belonging to the families of Gonostomatidae (1), Microstomatidae (2), Myctophidae (8), Phosichthyidae (2), Sternoptychidae (2) and Stomiidae (1) were given. The length-weight relationship showed an isometric growth in 13 species. No differences between right and left otolith sizes were detected by t-test, so a single linear regression was plotted against standard length (SL) for otolith length (OL) and otolith width (OW). Data fitted well to the regression model for both OL and OW to SL, for each species (R 2 >0.8). These relationships offer a helpful tool in feeding studies and also provide support to palaeontologists in their research on fish fossils.Keywords: mesopelagic fishes, bathypelagic fishes, otolith, fish-otolith sizes, length-weight relationship, Mediterranean Sea. RESUMEN: Relaciones entre talla del otolito y talla del pez en algunos peces mesopelágicos y batipelá-gicos del Mediterráneo (estrecho de Messina, Italia). -En este trabajo se presentan las relaciones talla-peso y las regresiones entre la talla del otolito (longitud y anchura) y la talla del pez (SL) para algunos peces meso y batipelágicos que viven en el Mediterráneo central. Se incluyen imágenes y descripciones morfológicas de los otolitos (sagittae) de 16 especies de las familias Gonostomatidae (1), Microstomatidae (2), Myctophidae (8), Phosichthyidae (2), Sternoptychidae (2) y Stomiidae (1). La relación talla-peso muestra un crecimiento isométrico en 13 especies. No se encontraron diferencias relevantes (t-test) entre la talla del otolito derecho e izquierdo, por lo que se representó una sola regresión lineal entre la longitud estándar y los siguientes parámetros: longitud de otolite (OL) y la anchura (OW). Los datos se ajustaron bien al modelo de regresión lineal para OL y OW, para todas las especies (R 2 >0.8). Las relaciones obtenidas puede ser utilizadas como instrumento en estudios de alimentación y para sustentar estudios de paleontología sobre peces fósiles.Palabras clave: peces mesopelágicos, peces batipelágicos, otolito, pez-otolito, relación talla-peso, Mediterráneo. 2010, 605-612, Barcelona (Spain) Scientia Marina74(3) September

“…Attacks were either bites or ingests, and the weighted attack rate for each substrate was defined as the sum of bites and ingests, weighted by the estimated weight of the attacker. Weights were calculated using published lengthweight exponential curve parameters for each species (Stergiou & Karpouzi, 2001;Koutrakis & Tsikliras, 2003;Valle et al, 2003).…”

Predation of fish assemblages in seagrass meadows was examined in the field and in tank experiments. Lure trolling indicated that (1) total abundance of fish was higher on bare sediment where small fish (\5 cm), including juveniles, predominated; (2) abundance was lowest in seagrass where large fish ([15 cm) predominated; (3) large ambush predators, primarily the grass goby and European eel, were almost completely restricted to seagrass; (4) the predation mode in seagrass was almost entirely ambushing or stalk-attacking, while the predation mode on bare sediment was almost entirely chaseattacking; (5) ambush predation was far more successful than chase-attack predation; and (6) overall predation risk was approximately three times higher in seagrass. Tank experiments showed that piscivory success of the grass goby was higher than that of the most common chase-attacker, the black goby, and the presence or absence of artificial seagrass, regardless of density, had no significant effect on predation success of either species. Guts of the grass goby contained food items of a wider size range that averaged twice the size of those of the black goby. Our results confirm our prediction that the risk of predation, especially of small/juvenile fish, is higher in seagrass meadows than at adjacent bare substrate, and this risk differential is explained by the presence of larger, more efficient ambush predators restricted to seagrass, and the scarcity of large chaseattack predators in the Novigrad Sea.

Weight-length relationships for selected fish species of the western Mediterranean Sea

Abstract: Weight-length relationships are presented for 24 species of the western Mediterranean Sea (Spain). These species were selected from samplings made during November 1995. The captures were made by beam trawl in Posidonia oceanica meadows up to depths of 20-22 m.
