    ABSTRACT
    Islands are important ecosystems for biodiversity and also represent a refuge area for many species, often threatened, that live on them. The Libyan coastline is characterized by the presence of many islands. In term of biodiversity hotspots, eight important sites have been identified in Libya. Al-Gara is one of these sites as important island ecosystem; it was declared as Marine Protected Area (MPA) according to the resolution of the Minister of Environment No. 272 of 2021, which includes the area surrounding the island. This island is annually hosting the biggest colony of the Lesser crested tern Thalasseus bengalensis (Lesson, 1831), the main breeding site for this species in the Mediterranean, and it is also a breeding ground for the European shag Phalacrocorax aristotelis (Linnaeus, 1761). Fieldwork was conducted on February and May 2023. Eleven (11) species of Macrophytes have been collected during this study, 17 species of Molluscs, four Crustaceans and 16 Fish species including five non indigenous species. Illegal fishing and illegal fishing gears, fishing in critical ecosystems, invasive species, overfishing and oil pollution are the most important threats to Al-Gara MPA.

    National Inventory and status of Chondrichthyes in the South Mediterranean Sea (Libyan Coast)

    ABSTRACT
    Libya has the longest coastline in the southern Mediterranean Sea, which is distinguished by the diversity of habitats and marine species; chondrichthyans are one component of this diversity. They are vulnerable to overexploitation due to their reproduction pattern and are generally regarded as a few resilient species. A total of 59 Elasmobranchs belonging to 24 families have been recorded along the Libyan coast out of about 88 documented species (FAO, 2018a; FAO, 2018b; Serena and Barone, 2023). Most of these species breed in the central part of Libya (Gulf of Sirt). A total of 8 elasmobranchs species were identified as by-catch in the Libyan tuna longline fishery (Prionace glauca, Isurus oxyrinchus, Odontaspis ferox, Alopias superciliosus, Heptranchias perlo, Mustelus mustelus, Pteroplatytrygon violacea and Carcharhinus plumbeus). The Tiger shark, Galeocerdo cuvier, is the most recently documented species on the western coast of Libya. This study provides some important information on elasmobranchs in Libyan waters to fill the gap of knowledge about these species in Libya and the southern Mediterranean regions.
