Analyses the impacts of non-indigenous species on the Mediterranean and the Black Sea. For example, the study finds that the invasive comb jelly Mnemiopsis leidyi has caused a loss in biodiversity and a decrease in fish catch in the Black Sea.
Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review, in addition to providing images and descriptions of relevant species to aid in identification, presents a unique historical and regional perspective on these species' impacts, based on many years' worth of research. The Black Sea's primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west, with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.
