Index of Average Error (IAE) suggested that measurement of TL had significantly lower average errors compared to SL and FL for all species (p<0.001). The length–length linear regressions were all highly significant (p<0.001) and analysis of covari-ance (ANCOVA) revealed no significant differences in the slope of length–length relationships of the measurements among researchers for all fish species (p>0.05). Analysis of variance (ANOVA) results indicated that there was no significant difference between the personal measurements of different type of lengths. The best length measurement of fishes is discussed.

According to fishermen observations, specimens belonged to a school of 10 individuals, with a length into range of 40-45 cm (TL). The school swam for 2 days from off north Cyprus to Beşadalar, near the surface (1-5 m), vicinity the transport cage (60 m diameter, 25 m depth) towed behind the boat. Towing speed during transport was a 1 knot, typical of transport cages of this kind, to avoid damaging the bluefin tuna. The occurrence of S. ovalis in Turkish waters was known previously only in Izmir Bay and Iskenderun Bay, respectively. Previous S. ovalis records have been justified in different ways, most of them connected to environmental factors. Although the environmental factors hypothesis is not to be undervalued, we suggested that the "pursuit" habit of S. ovalis could be perhaps a transitional way for the species.

The study period was between 01 March 2013 and 28 January 2014. A total of 24 field studies and 120 free diving observations (FDOs) were made. FDOs have taken place 2 times per month between 0700 and 1200 hrs. The surface seawater temperatures were measured on an average as 21.36 ± 4.63, with a minimum 15.61 ºC (March 2013) and a maximum 27.90 ºC (August 2013). Sandbar sharks were observed at temperatures over 20° C in the area with salinities 36.18 and 40.50 ppm. Most of the observations occurred in K4 area (34.8%), followed by K3 (25.9%), K2 (20.7%), K1 (9.6%), and K5 (8.9%). Sharks are active in the morning hours between 0700 and 0859 hrs (72.6%). We encountered sandbar sharks 39 times in 120 FDOs, and totally 135 individuals were counted. Key words: Carcharhinus plumbeus, Bo...

The length-weight relationship was W= 0.019*L 2.93 (n=790; r 2 = 0.95). Age data based on otoliths were comprised from 0 + to 4 + . The parameters of the fitted von Bertalanffy growth equation were L ∞ = 11.05 cm, k = 0.447 year -1 , t 0 = -0.480. Macroscopic gonad examination and analysis of the monthly values of the GSI, indicated that reproduction occurs between April and August. Individuals become sexually mature at around 6.69 cm total length (TL) (a size that can be reached on 1.84 years) for both sexes. Sex ratio (female:male) was found as 1.00:0.74.

Additionally, a bibliographic review of such relationships for these species was conducted. Based on the results, the values of b parameter varied between 2.477 and 3.496, with one species having isometric growth, five negative and six positive allometric growth. Furthermore, for Aulopus filamentosus there exist no information in the literature, whilst for Callanthias ruber and Gnathophis mystax, there are no such information available from the Mediterranean.

Divings were carried out at 18 stations, in Gökova Bay (4), Güllük Bay (2), Marmaris Bay (5), Hisarönü Bay (2), Fethiye Bay (3), Bodrum (1) and Datça (1). Cassiopea andromeda which is the first lessepsian scyphozoan species reported from the Mediterranean, lives upside-down on the sandy and muddy bottom of the sea floor. Therefore, abundance and distribution of this species were determined by scuba divings. Quadrate method was used in divings. Individuals were counted in quadrats of 10m2 (5m x 2m) and countings were averaged and calculated to numbers of individuals per 100 m2. C. andromeda was observed between April and November when the water temperature was high (18,08°C - 29,76°C) in the area. Also, zooplankton abundance began to increase from May. Abundances of C. andromeda were maximum from May to October when zooplankton peaked. Maximum a...

Türlerin besin kompozisyonlarını belirlemek için mide içerikleri incelenmiştir ve türlerin trofik durumlarının özellikle karnivor seviyede yer aldığı görülmüştür. Beş predator türün besin kompozisyonunda iki esas av grubu bulunmuştur: Crustacea (copepodlar ve isopodlar gibi) ve Chaetognatha (Sagitta spp.).

Mayıs 2013 ile Nisan 2014 periyodunda gerçekleştirilen çalışma, 12 aylık kesintisiz izleme yapılan ilk çalışmadır. Toplamda 28 arazi çalışması ve 140 SDG’i yapılmıştır. SDG’i genelde her ay için 2 kere, 07:00 ile 12:00 saatleri arasında yapılmıştır. Alandaki ortalama deniz suyu temperatürü 21.36 ± 4.63 ºC olarak hesaplanmış, temperatür minimum 15.61 ºC (Mart 2014) ve maksimum 27.90 ºC (Ağustos 2013) olarak ölçülmüştür. Alanda deniz yüzey suyu temperatürü 20° C’nin üzerine çıktığında kum köpekbalıkları gözlenmeye başlamış, bu temperatürden daha düşük sıcaklıklarda köpekbalığı gözlenmemiştir. Köpekbalıkları 7 ay alanda gözlenirken, 5 ay (Aralık, Ocak, Şubat, Mart ve Nisan) hiç köpekbalığına rastlanmamıştır. Köpekbalığı gözlemlerinin çoğu K4 (%39.6) bölgesinde olurken, bunu K3 (%26.0), K2 (%17.8), K1 (%8.9) izlemiştir. Kum köpekbalığının sabah saat 07:00 ile 08:59 periyodunda aktif olduğu bulunmuştur (%76.9). 140 SGD’ının 51’inde köpekbalığı ile karşılaşılmış ve toplamda 169 kum köpekbalığı bireyi sayılmıştır.

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.

Mayıs 2013 ile Nisan 2014 periyodunda gerçekleştirilen çalışma, 12 aylık kesintisiz izleme yapılan ilk çalışmadır. Toplamda 28 arazi çalışması ve 140 SDG’i yapılmıştır. SDG’i genelde her ay için 2 kere, 07:00 ile 12:00 saatleri arasında yapılmıştır. Alandaki ortalama deniz suyu temperatürü 21.36 ± 4.63 ºC olarak hesaplanmış, temperatür minimum 15.61 ºC (Mart 2014) ve maksimum 27.90 ºC (Ağustos 2013) olarak ölçülmüştür. Alanda deniz yüzey suyu temperatürü 20° C’nin üzerine çıktığında kum köpekbalıkları gözlenmeye başlamış, bu temperatürden daha düşük sıcaklıklarda köpekbalığı gözlenmemiştir. Köpekbalıkları 7 ay alanda gözlenirken, 5 ay (Aralık, Ocak, Şubat, Mart ve Nisan) hiç köpekbalığına rastlanmamıştır. Köpekbalığı gözlemlerinin çoğu K4 (%39.6) bölgesinde olurken, bunu K3 (%26.0), K2 (%17.8), K1 (%8.9) izlemiştir. Kum köpekbalığının sabah saat 07:00 ile 08:59 periyodunda aktif olduğu bulunmuştur (%76.9). 140 SGD’ının 51’inde köpekbalığı ile karşılaşılmış ve toplamda 169 kum köpekbalığı bireyi sayılmıştır.
