Öğe Age, growth, sex-ratio, spawning season and food of golden banded goatfish, Upeneus moluccensis Bleeker (1855) from the Mediterranean and south Aegean Sea coasts of Turkey(Elsevier Science Bv, 1999) Kaya, M; Benli, HA; Katagan, T; Ozaydin, OThe length, growth, age composition, spawning season, sex ratio, and food of golden banded goatfish (Upeneus moluccensis) were studied on the basis of 711 specimens from the eastern Mediterranean Sea. Females made up 75.25% and males 24.75% of the species, The fork length of females ranged from 8.6 to 17.8 cm, and of males, from 8.5 to 16.1 cm. The length-weight relationships estimated for males and females were: W = 0.01051 L-3.15006 and W = 0.00607 L-3.35215, respectively. Mean fork length at age data derived from otolith readings were used to estimate the growth parameters of the von Bertalanffy equation. The estimated parameters were: L-infinity = 26.20 cm, K = 0.11, t(o) = -4.08 for females, and L-infinity = 23186 cm, K = 0.12, t(o) = -3.69 for males. The maximum age group determined was VI for females and V for males. Age group III was the dominant one in females and age group II in males. The monthly values of gonadosomatic index (GSI) of females indicated that the spawning occurred mainly in August and September. Golden banded goatfish fed mainly on Crustacea.

The morphological, biometrical and distributional features of each species as well as a checklist of species of Autolytinae and Exogoninae reported from the Levant coasts are provided.Öğe Autolytinae and Exogoninae (polychaeta : syllidae) from northern Cyprus (eastern Mediterranean sea) with a checklist of species reported from the Levant Sea(Rosenstiel Sch Mar Atmos Sci, 2003) Cinar, ME; Ergen, Z; Benli, HAFaunistic analysis of a total of 77 benthic samples collected in different biotopes and depths from northern Cyprus in 1997 and 1998 yielded 36 species and one subspecies of syllid polychaetes belonging to Autolytinae and Exogoninae, of which three species (Exogone (Parexogone) wolfi San Martin, 1991, Sphaerosyllis longipapillata Hartmann-Schroder, 1979 and Sphaerosyllis sp. 2) are new to the Mediterranean, seven species to the eastern Mediterranean, 23 species to the Levantine Sea and 32 species to the Cypriot coast.

For this purpose a total of 292 bottom trawls were carried out seasonally during 1991 and 1992. Sampling depths ranged between 20 and 500 m. A total of 30 species were recorded, with Sepiola intermedia and Histioteuthis bonnellii being found in the Aegean Sea for the first time. It was estimated that the proportion of cephalopods in the total catch taken by commercial fisheries was 11.16 % in the northern Aegean Sea and 8.46 % in the southern Aegean Sea.Öğe Contribution to the knowledge of the crustacean fauna of Cyprus(Laser Pages Publ Ltd, 2001) Kocatas, A; Katagan, T; Benli, HAA total of 266 crustacean species were identified from material collected off northern Cyprus from 10-19 May 1997 and from 12-21 July 1999. Among the species determined, 179 constitute new records, increasing the number of crustaceans known from Cyprus to 343 species.Öğe On the cephalopod fauna of northern Cyprus(Laser Pages Publ Ltd, 1998) Salman, A; Katagan, T; Benli, HAÖğe Summertime diel variations in the diet composition and feeding periodicity of red pandora (Pagellus erythrinus) in Hisaronu Bay(Cambridge Univ Press, 2001) Benli, HA; Kaya, M; Unluoglu, A; Katagan, T; Cihangir, BIn summer 1997, the stomach contents of 235 red pandora collected by bottom trawl from Hisaronu Bay in the southern Aegean coast of Turkey, were analysed. It was observed that red pandora is predominantly a diurnal feeder. More intensive feeding started in the afternoon, reaching its maximum value in the evening and continued until dusk. The minimum feeding intensity occurred during the night. The diet was found to consist primarily of polychaetes, especially Glyceridae, and crustaceans, mainly Natantia. No significant diel variation was observed in the diet composition of red pandora.Öğe Variations in the feeding intensity and diet composition of red mullet (Mullus barbatus) during 24-h period in the summertime in Hisaronu Bay(Cambridge Univ Press, 2002) Unluoglu, A; Cihangir, B; Kaya, M; Benli, HA; Katagan, TDiet Feeding pattern of red mullet in the Hisaronu Bay was studied from samples collected by bottom travel during a 24-h period in the summer of 1997. Feeding activity of red mullet commenced at dawn and reached its maximum value at noon. During the period between noon to early evening, feeding intensity showed clown and then showed a small increase towards sunset. After sunset, the feeding activity nearly stopped and fish with empty stomachs increased. At night almost all stomachs were empty. Polychaetes, decapods, bivalves, and amphipods were the major prey groups in the diet of red mullet and no significant diel variations were observed in the relative importance of these groups.Öğe Vertical distribution and abundance of juvenile cephalopods in the Aegean Sea(Inst Ciencias Mar Barcelona, 2003) Salman, A; Katagan, T; Benli, HAThis study was carried out in northern (Saros Bay) and southern (Gokova Bay) parts of the Aegean Sea. In pelagic samplings, Hamburg Plankton Net (HPN) was used. Samplings were done out at four different periods of a 24 hour day; sunrise, noon, sunset and midnight. Horizontal hauls were carried out at depths of 100, 350 and 650 m. As the result of 24 hauls in both parts of the Aegean Sea, one hundred juvenile specimens were sampled and 14 species were determined. Juvenile cephalopods were mostly frequent at 350 m. Among the determined species, Chtenopteryx sicula (Verany, 1851), Brachioteuthis riisei (Steenstrup, 1882), Illex coindetii (Verany, 1839), Thysanoteuthis rhombus Trochel, 1857 and Argonauta argo Linnaeus, 1798 juveniles are being reported for the first time in the Aegean Sea. 28% of the catches were from the northern Aegean and the remaining 72% were from the southern Aegean. Heteroteuthis dispar (Ruppell, 1844) was the most common species.Öğe Vertical distribution and abundance of juvenile cephalopods in the Aegean Sea(Inst Ciencias Mar Barcelona, 2003) Salman, A; Katagan, T; Benli, HAThis study was carried out in northern (Saros Bay) and southern (Gokova Bay) parts of the Aegean Sea.
