Published: Aug. 25, 2023

This work presents refined, updated subregional and regional non-indigenous species (NIS) inventories for the Mediterranean Sea, validated by national taxonomic experts, with records observed until December 2020. These datasets will be used as baselines implementation of Integrated Monitoring Assessment Programme (IMAP) Quality Status Report 2023. In total, 1006 have been found in marine brackish waters. The highest numbers NIS were Israel, Türkiye, Lebanon Italy. Approximately 45 categorized data deficient, either due to lack consensus on their alien status or validity identification. Polychaeta, Foraminifera macroalgae groups controversial species. There was a general increase yearly rate new introductions after late 1990s, which appears slowing down last decade, but this may confounded reporting lags differential research efforts. Between 1970 2020 there has steep proportion shared present throughout all four subregions, are predominantly transported via shipping recreational boating. While Lessepsian gradually spreading westwards northwards, is still considerable invasion debt accumulating eastern central Mediterranean.

Lessons From the Western Atlantic Lionfish Invasion to Inform Management in the Mediterranean

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: April 20, 2022

Major invasions of Indo-Pacific lionfish ( Pterois volitans and P. miles ) are underway in the Western Atlantic Ocean Mediterranean Sea. While establishment is perhaps most well-studied marine fish invasion to date, rapidly expanding more recent has received less attention. Here we review synthesize successes failures from two decades management give policy recommendations for their Mediterranean. Two failed approaches that were attempted multiple times advise against (1) feeding native promote predation (2) implementing bounty programs incentivize harvest. Broadly, important lessons recommend include conducting routine removals by spearfishing with scuba, which can effectively suppress local abundances lionfish; encouraging development recreational commercial fisheries, long-term, sustainable population control; and, (3) engaging communities resource users (e.g., removal tournaments), concurrently achieve objectives promoting removals, market-development, research, public education. Managers often needed adapt current conservation policies enable areas where scuba was otherwise prohibited purposes. The risk abusing these mitigated through use gear restrictions, diver trainings, participatory integrated divers stakeholder organizations research management. Our practices Sea found many our recommended not being done indicate potential opportunities implement these. We expect fully work continues towards multinational cooperation facilitate regional coordination control, efforts respect invasion. As other major biological invasions, unconstrained political borders control will require rapid strategic broad among between governments stakeholders.

Abstract With over a thousand of introduced species, the Mediterranean is most heavily invaded marine region in world. Yet, spatio‐temporal dynamics this bioinvasion has never been analysed. Examination comprehensive dataset 4015 georeferenced observations, extracted from scientific literature, allowed (i) reconstructing invasion and introduction post‐introduction exotic fish (ii) calculating spread rates, (iii) investigating time correlates since introduction. Our analysis encompasses 188 species that entered 1896 to 2020, including 25 Atlantic naturally expanded their range through Strait Gibraltar. Cumulative occurrences, reported 264 distribution maps, documented progressive expansion represented patterns associated with three routes: Suez Canal (CAN); other human‐mediated vectors (HM) Gibraltar (NRE). The arrival rate all routes increased steeply after 1990, without sign saturation. Data highlighted some temporal geographical patterns, such as effect eventual weakening biogeographical barriers by Sicily North Aegean Sea asymmetrical occurrences along northern southern coasts. Finally, there was an exponential increase secondary rates CAN NRE immigrants, more recent introductions achieved fastest expansions. findings provide detailed spatially explicit summary massive changed history biota represent remarkable example rapid biotic homogenization global ocean.
