Cranial Morphometrics of a Stranded Common Bottlenose Dolphin Tursiops truncatus (Montagu, 1821) in Mersin Bay (Northeastern Mediterranean, Turkey)

AYAS, Deniz | Çiftçi, Nuray

On 10 November 2017, a young male common bottlenose dolphin Tursiops truncatus (Montagu, 1821), 185 cm in total length (TL), was found dead on the Mersin Marina (36°46'065"N, 34°34'212"E) in Northeastern Mediterranean coast of Turkey. Measurements of the sample performed and documented. The specimen buried to obtain the skeleton of the individual. At the end of this process, the sample was deposited in the Museum of the Systematic, Faculty of Fisheries, Mersin University, (Catalogue no: MEUMC-17- 11-001). The morphometric measurements can contribute to ongoing fisheries biology and taxonomic studies of T. truncatus from Mediterranean Sea waters. During routine fishing activities, common bottlenose dolphins can be caught in fishing nets and drowned. This issue leads to an extra pop...

First Record of the Pempheris rhomboidea (Kossmann Räuber, 1877) from Mersin Bay, Northeastern Mediterranean Sea

Çiftçi, Nuray | Ayas, Deniz

In this study, eight individuals of Pempheris rhomboidea (Kossmann & Räuber, 1877) were for the first time caught in the Mersin Bay, Northeastern Mediterranean Sea. Some morphometric and meristic characters of these individuals were measured. The average standard length (SL): 90.13 mm, total length (TL): 112.62 mm, the length of longest pectoral fin (LPF): 25.88 mm, the length of longest dorsal fin ray (LDF): 21.25 mm, SL/LPF: 3.88, SL/LDF: 4.24, A: III, 39-42; D: VI, 9; LL pore scales: 55-58. The ratio of eye diameter (ED) to standard length (SL) is 7.95. The presence of the non-indigenous Pempheris rhomboidea was reported for the first time from Northeastern Mediterranean Sea and second time fromTurkish marine waters.

Ayas, Deniz | Çiftçi, Nuray

Eighty-five specimens of the lesser spotted dogfish, Scyliorhinus canicula Linnaeus, 1758, was caught by a bottom trawl in the international waters of the Mersin Bay in May 2018. Some of the caught individuals were preserved in 4% formalin and was deposited in the Museum of the Systematic, Faculty of Fisheries, Mersin University, (catalogue number: MEUFC-18-11-079). The depth of sampling area is between 274 and 641 m. A total of 13 trawling operations were carried out. The total number of caught individuals was 85 and on average 5 individuals were caught in each operation. The other cartilaginous fishes caught apart from S. canicula were Galeus melastomus (1 individual), Squalus acanthias (4 individuals), Etmopterus spinax (11 individuals) and S. canicula made up 84.16% of all cart...

Accumulation and Effect of Chromium on Protein and Glycogen Levels of Palaemonetes pugio

Çiftçi, Nuray | Karaytuğ, Sahire | Karayakar, Fahri | Ay, Özcan | Cicik, Bedii

Total metal accumulation and the levels of total protein and glycogen were measured in Palaemonetes pugio after exposing the animals to 0.05, 0.1 and 0.2 ppm concentrations of chromium over 1, 7 and 15 days. Metal accumulation in tisuues was measured using atomic absorbtion spectrophotometric techniques and the levels of total protein and glycogen were determined Lowry and Anthron methods, respectively. No mortality was observed under the effect of chromium at any concentrations and exposure periods tested. Total metal accumulation increased with increasing concentrations of chromium at given exposure period while total protein and glycogen levels showed a decrease on day 15th compared with day 1.
