In this study, Bomolochus unicirrus Brian, 1902, a species of parasitic copepod belonging to the family Bomolochidae (Claus, 1875), was reported for the first time from the north-eastern Mediterranean waters off the Turkish coast. Parasites were collected from the gill filaments of the European barracuda, Sphyraena sphyraena(L.)captured by trawling in Iskenderun Bay, Turkey. The morphological features of B. unicirrus were Redescribed and illustrated based on the newly collected material. Key diagnostic characters and newly observed details in some structures are highlighted and supported by using scanning electron microscopy (SEM). Differences and simply overlooked details in previous descriptions of B. unicirrus, are discussed in detail. In addition, morphological comparisons between presently reported species and the other species of the genus Bomolochus Nordmann, 1832 were also presented.

The purpose of this study was to determine the accumulation levels of ten metals (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) in the muscle tissues of Actina equina indvduals. A total of 120 individuals of A. equina were collected at six different stations in İskenderun Bay in spring 2013. The accumulation levels of heavy metals in the tissues were found to vary significantly among stations. The mean concentrations of Fe were the highest at Samandağ station (105.11 ± 74.28 mg/kg) whereas the lowest average value of Co (0.84 ± 0.10 mg/kg) was obtained at Dörtyol station. Heavy metal concentratıons in muscle tissue of A. equina were ordered as Fe>Zn>Mn>Al>Cr>Cu>Pb>Ni>Cd>Co, respectively. This study is the first detailed bioaccumulation study conducted with A. equina in İskenderun Bay.

Age and growth of the common guitarfish (Rhinobatos rhinobatos) were estimated from the north-eastern Mediterranean coast of Turkey. A total of 115 common guitarfish (66 females and 49 males) were sampled. Age determinations were carried out using vertebral sections. Alcian blue dying techniques were used to enhance the visibility of the band on vertebrae. The techniques have been used for the first time on elasmobranchs vertebrae successfully in this study. A total of 97 vertebrae of 115 were visible on the vertebral band in this study. Male and female common guitarfish ranged in age from 1 to 15 and 1 to 24 y respectively. Total length ranged from 42 to 147 cm for females and 39 to 124 cm for males.The relationships between total length (TL) and total weight (TW) were presented as TW = 0.0014*TL3.1672 (R2 = 0.98) for females, TW = 0.0012*TL3.1947 (R2 = 0.98) for males and TW = 0.0012*TL3.1915 (R2 = 0.98) for both sexes. The parameters for von Bertalanffy growth curves were estimated as Linf  = 137.70±9.38 cm, K = 0.159±0.047, to = −2.180 ± 0.90 for pooled data.

The swimming crab, Charybdis (Goniohellenus) longicollis Leene, 1938, is a Lessepsian migrant into the Mediterranean and little is known about its biology in Iskenderun Bay, north-eastern Mediterranean, Turkey. The size of crabs, sex-ratio and spawning period of this species was defined from 951 specimens in order to understand their reproduction and development in the NE Mediterranean Sea. The crabs were found to occur throughout the year. Carapace width (CW) ranged between 7.22 to 100.60 mm and total weight ranged from 1.34 to 164.09 g. Male-female sex ratio was 0.6:1. Highest gonado-somatic index (GSI) was seen in March and September for females and in May for males. Ovigerous females were present throughout the year, with peak spawning activity in July and September. The CW of the ovigerous female crabs ranged between 23.71 and 95.93 mm. In winter months, GSI of males and females decreased. However, spawning season of C. (G.) longicolis in Yumurtalık Cove was observed throughout the year.
