In this review the research on the anticoagulant and antilipaemic activity of sulfated and synthetically modified polysaccharides extracted from marine macro algae between 1913 and 2018 was summarized and the results were compared with a long known natural polysaccharide from animal sources, heparin which contain N-sulfate group. The highest anticoagulant activity of algal sulfated polysaccharide was obtained from Dictiyota menstrualis, red alga, found to be 4.8 times more active than heparin. Antilipaemic activity of some algal sulfated polysaccharides showed similar activity as heparin.

Keywords: Anticoagulant, antilipaemic, polysaccharides

Plotosus lineatus is a venomous Lessepsian fish species present in the south-eastern Mediterranean since 2002. It has been identified as one of the priority marine invasive alien species (IAS) likely to threaten native ecosystems and human well-being throughout the Mediterranean and within EU marine waters. It was thus selected as one of the species to be risk assessed and considered for management under the EU IAS Regulation. This work describes the main findings of the Risk Assessment (RA) of P. lineatus and discusses possible management measures. The species has a high likelihood to enter the RA area through natural dispersal and the possibility of “facilitated” or accidental escapes from domestic or public/private aquaria, has been established in some parts of the Mediterranean and is very likely to establish throughout the Mediterranean and possibly the Black Sea. Potential population explosions can instigate major environmental impacts on native community structure and ecosystem functions through competition, predation and habitat use; additionally, its painful and potentially dangerous sting poses a serious health risk. The risk assessment identified a moderate rate of spread due to depth limitations to dispersal, which can facilitate population control and containment efforts, should they be needed. Commercialization of the species for consumption and biomedical research can be an option for long-term management.

Status of marine alien species along the Libyan coast

Department of Zoology, Faculty of Science, Tripoli University, LIBYA


The number of marine alien species in Libyan waters has increased from 63 (known until the end of 2013) to 73 in the present study. This work deals with the present status, distribution and characteristics of marine alien species and their impacts along the coast of Libya, almost 2000 km long. The highest percentage was fishes (32.88%), followed by macrophytes (21.92%), molluscs (16.44%), crustaceans (13.70%), and parasites (9.59%). Some of these species have successfully adapted themselves to various topographies and habitats in the Libyan coasts, which resulted in the change in biodiversity in the area. Some fish were accompanied by parasites and others have become hosts for native parasites; seven alien parasite species (Nybelinia africana, Neoallolepidapedon hawaiins, Allolepidapedon petimba, Glyphidohaptor plectocirra, Tetrancistrum polymorphum, Apounurs sigani and Hatschekia siganicola) were recorded in three lessepsian fish species. Moreover, the toxic effect of poisonous fish (Lagocephalus sceleratus) was investigated as it caused fatalities and severe intoxication for some fishermen. Its population has dramatically increased, with high numbers of juveniles and adults reported in some bays especially in the eastern part of Libya. Alien Siganus spp. have competed with the native herbivore fish Sarpa salpa. Furthermore, some alien fishes have become commercially valuable in Libya. This paper highlights the biological invasion in the Libyan coasts in an attempt to fill the gap of knowledge on the alien species in the southeastern Mediterranean coast.

Notes on the occurrence of smalltooth sandtiger shark, Odontaspis ferox (Lamniformes: Odontaspididae) from Antalya Bay, eastern Mediterranean, Turkey

Hakan Kabasakal, Erdi Bayrı

Ichthyological Research Society, Tantavi mah., Menteşoğlu cad., İdil apt., No: 30, D: 4, 34764 Ümraniye, İstanbul, TURKEY


On 11 March 2019, a female specimen of Odontaspis ferox, was incidentally caught by a commercial bottom trawler, towed at the depths between 100 to 120 m, in Antalya Bay. Total length of the specimen was 400 cm. Based on the recent Red List assessment of Mediterranean elasmobranchs, O. ferox is a rare and endangered shark species. Capture of the mature females creates a significant threat to the survival of the species. Therefore, promoting fishermen to release live specimens, appears to be an urgent, feasible first step in the protection of this rare shark in Turkish waters.

The present study reports the first record of Munida curvimana and second record of Planes minutus in Turkish waters. A male specimen of M. curvimana was collected by a commercial set net in Antalya Bay, Turkey in 2007. A male specimen of P. minutus was found on the loggerhead sea turtle that was captured by driftnet as a bycatch in Fethiye Bay in 2005. The morphometric characteristics and the updated distribution of squat lobster and Columbus crab in the Mediterranean Sea are presented.
