Abstract The marine leech, Stibarobdella moorei was collected from dorsal parts of the thornback ray (Raja clavata) and angelshark (Squatina squatina) (Elasmobranchii) captured by commercial trawl vessels as non-target species from depth of 50 meters of Antalya Bay which is located in the eastern Mediterranean coast of Turkey on April and July, 2013. The leeches caused two typical lesions on epidermal tissues of both hosts: the major lesion by oral sucker and a minor one by caudal sucker. The leeches were identified as Stibarobdella moorei which has not been reported from elasmobranches in the Turkey’s Mediterranean shores. This study represents new host and geographical records.

New information on distribution of marine leech, Pontobdella muricata (Linnaeus, 1758) is given here. One leech was observed on the dorsal surface of Thornback Ray, Raja clavata (Linnaeus, 1758) that was caught in 2013 in the Antalya, Turkey. This is a new record for the eastern Mediterranean coast of Turkey.

The Difference

Small-scale fisheries constitute an important component of coastal human societies. The present study describes the small-scale net fisheries on Kalymnos Island (south-east Aegean Sea) that harbors the largest small-scale fleet in the eastern Mediterranean Sea. In addition, this study aims to evaluate their characteristics and economics. Relevant métiers were identified through a multivariate analysis by inputting the main resources and fishing gear data that were recorded during landings. Four main practices were observed being used as fishing gears, gillnets and trammel nets, targeting the species Mullus barbatus, Boops boops, Mullus surmuletus, Scorpaena porcus, and Sepia officinalis. Further analysis, which incorporated data concerning the type of the gear used, revealed 11 distinct métiers. Most of these métiers are practiced by other Mediterranean small-scale fisheries as well, in terms of target species, gear and seasonality. However, the métier that had its target species as B.boops is not practiced in other Mediterranean small-scale fisheries. The seasonal rotation of métiers was determined by the availability of different species rather than their market price. The results revealed the difference in fishing practice used by the fishermen in the study area compared to other fishing practices in the Mediterranean Sea. In particular, the fishermen of this study area targeted more species (B.boops) with a very low market price. They also provided essential information for the development and implementation of management plans aiming at the sustainability of small-scale fisheries.

Aims: In this study, an individual of H. griseus was caught from the Mersin Bay and this ichthyologic note presents a new female record of H. griseus for Mersin Bay, Mediterranean coast of Turkey. This study aims to contribute to the chronological records of the species in the Mediterranean Sea. Place and Duration of Study: Yeşilovacık bay is a small bay in the west of Mersin Bay. Yeşilovacık bay which lies at approximately 36°07’n latitude, 33°37’e, longitude and about 143 km Western of in Mersin province, Turkey. Sample: On 19 March 2018 blunthose sixgill shark specimen was measured and then deposited in the Museum of the Systematic, Faculty of Fisheries, University of Mersin. Methodology: A female specimen of H. griseus with a total length (TL) of 350 cm (400 kg) was captured by a commercial trawl at a depth around of 280 m of the Yeşilovacık Bay (Northeastern Mediterranean Sea), Turkey. Total length was measured to the nearest 1 mm and the weight of the specimen was determined to the nearest kilogram. Results: Measurements of the specimen are presented and compared with the previous records of H. griseus in the Eastern Mediterranean coast of Turkey (Iskenderun Bay), which are given in Table. The identification was carried out according to the previous report. Conclusion: To date specific conservation measures are not known for this species for the Northeastern Mediterranean coast of Turkey. Thus, the effect of coastal fishery for sharks should be regularly monitored and protection measures should be taken in this region in order for this shark species to continue their conservation for the next generation.

Distribution And Ecology

A survey has been carried out at four Israeli rocky sites to evaluate the diversity of the amphipod fauna on various hard substrates, still scarcely monitored, as potential pabulum for amphipod crustacean species. A survey of shallow rocky reefs along the Mediterranean coast of Israel recovered 28 species and integrated the Amphipoda checklist for the country ofIsrael with 12 newly-recorded species. Such renewed national list includes Maera schieckei Karaman & Ruffo, 1971, a rare species endemic to the Mediterranean Sea, recorded here for the first time from the southern Levant Basin. The species, described from specimens collected in the Tyrrhenian Sea in 1970, has been only recorded eight times within the whole Mediterranean Sea. A revision of the bibliography on the distribution and ecology of M. schieckei showed that, although mentioned only for the western Mediterranean basin by some authors, it is listed in the checklist of amphipods of the Aegean Sea and neighbouring seas and has been found in the eastern Mediterranean basin since 1978. Maera schieckei was rarely found in the Mediterranean, one of the most studied marine biogeographic region as concerns the amphipod fauna; and the species seems to prefer bays or gulf areas. The role of updating and monitoring faunal composition should be re-evaluated.

Plocamopherus ocellatus, a conspicuous but very rare Erythraean nudibranch, was first collected in the Mediterranean Sea off the Israeli coast in 1977, but no additional observations from Israeli waters were recorded in the scientific literature. Biodiversity assessment surveys of the hard bottom biota off the Mediterranean coast of Israel and sightings by recreational divers/underwater photographers in the past dozen years seem to support the presence of a local self-sustaining population off the Israeli coast.

Abstract Concentrations of eight trace elements (V, Cr, Ni, Cu, Zn, As, Cd, and Pb) were investigated in Posidonia oceanica blades and in the sediments sampled from 23 stations along the Turkish-Mediterranean Sea coast. Trace element (TE) concentration in both sediment and P. oceanica showed a statistically significant distribution among sampling stations. Most of the TE concentration in samples varied remarkably among stations without a consistent trend. Concentrations of Zn, Cd, Cu, and Pb in sediment of all of the sampling stations were determined as non-polluted based on the comparison with the sediment quality guideline index. More than quarter of the sampling stations were found as moderately or heavily polluted for Cr, Ni, and As. The mean TE concentrations found in the sediment sample in the present study were similar to the concentrations reported from the different parts of the eastern Mediterranean Sea. TE concentrations in P. oceanica were generally lower compared to the concentrations in the sediment except for Cd, Zn, and Cu. While positive correlation was found for Ni concentrations between sediment and P. oceanica samples, negative correlation was detected for V, Cr, Zn, Cu, As, and Cd concentrations between sediment and P. oceanica. The highest bioaccumulation factor in P. oceanica was calculated for Cd. The study area of the present study, especially the western sites (provinces of Antalya and Muğla) hosts millions of tourists annually and under the influence of intensive human activities in summer. Thus, coastal waters are heavily exposed to TEs and significantly positive correlations were detected between the anthropogenic TE pollutants (As, Cd, Cu, Zn, Pb, and V) and natural sourced TE (Ni and Cr).

The parasitic Isopod Nerocila bivittata was collected from caudal fins and body surface of dusky grouper (Ephinephelus marginatus) and mottled grouper (Mycteroperca rubra) captured by commercial trawl vessels as non-target species from Antalya Bay which is located in the eastern Mediterranean coast of Turkey. The parasites caused typically hemorrhages on caudal fins of both hosts. The parasitic isopod was identified as Nerocila bivittata which has not been reported from groupers in the worldwide. The study represents new hosts and geographical records.
