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

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.

Lionfish on the loose: Pterois invade shallow habitats in the tropical southwestern Atlantic

Frontiers in Marine Science, Год журнала: 2022, Номер 9

Lionfish ( Pterois spp.) evolved in the Indo-Pacific with predators and prey invaded regions (e.g., Caribbean Sea Mediterranean) where no such balance yet exists. In 2020, four lionfish were recorded on mesophotic reefs of Amazon offshore Coast Fernando de Noronha Archipelago. However, until now, there records invasive Brazilian nearshore waters or even a high number individuals. this article, we report continuing invasion process along Province by multiple sightings (72) from March to May 2022 estuaries, seagrass beds, artificial natural across 240 km coast. These are first coastal northeast Brazil shallowest (1–16 m) South Atlantic tropical waters. The largest simultaneous breakwaters, fishing weirs, marambaias (artificial used as grounds) Northeastern coast indicate that these man-made structures suitable habitats for species. Most (58%) weirs. Moreover, detection invasions marginal reefs, two marine protected areas characterized moderately turbid water sedimentation rates highlights adaptability lionfish, making it extremely difficult divers fishers capture them. We call an urgent management plan considering region hosts level endemism, rare and/or cryptic taxa, which increases risk impacts since primary prey.

Biology and ecology of the lionfish Pterois volitans/Pterois miles as invasive alien species: a review

The lionfish is an exotic invasive fish native to the Indo-Pacific, which established in western Atlantic Ocean and Caribbean Sea. Lionfish can affect fishes invertebrates through direct predation or competition for food. present review aims analyze most relevant characteristics of biology ecology as alien species, with emphasis on Cuba. We provide a current view well-known successful fish, we put this context information regarding Cuban waters, enriching background knowledge, giving novel information. compilation numerous publications subject has allowed more complete analysis essential aspects invader archipelago. consulted literature records that first report Cuba occurred 2007; subsequently, sightings were reported localities. In 2010, was considered currently various habitats, at depths up 188 m, throughout archipelago ( e.g. , coral reefs, mangroves, seagrass beds, submerged artificial structures). addition, it reached very high densities (12.42 ind./100 m 2 ), exceed those Indo-Pacific well many locations Western Atlantic. It been confirmed also presents guarantee its success invader, among them: less quantity diversity parasites than other found similar environments, number gametes gonads, reproductive activity during all year wide diet. important families diet have Pomacentridae, Gobiidae, Scaridae, Holocentridae, Mullidae, Labridae Acanthuridae; crustacean orders are Decapoda, Mysida, Stomatopoda Isopoda. Cuba, entire invaded region, investigations directed evaluate impact ecosystems, although there enough information, their results differ. Additional studies required assess predator after several years invasion larger geographic scale areas region. This knowledge will allow development effective control strategies. Periodic culling carried out MPAs strategy, some positive observed, such average size reduction; however, further efforts still required. Due importance study necessity provides, time, comprehensive from adequately contrasted previous areas, particularly, Greater Caribbean.

Climate Change Impacts on Marine Invaders: Analyzing Future Distribution and Ecological Niche Shifts of Pterois miles and Pterois volitans

Applied and Computational Engineering, Год журнала: 2025, Номер 123(1), С. 232 - 247

Опубликована: Янв. 7, 2025

Invasive lionfish species, Pterois miles and volitans, are poised for significant range expansion due to environmental changes their intrinsic adaptability. Utilizing Species Distribution Models (SDMs), this study predicts a marked increase in the future spread of these particularly as non-suitable areas transform into highly suitable habitats under projected climate change scenarios. Our findings indicate that both species expanding ecological niches invaded territories, where they increasingly occupy more dominant positions. This shift is likely facilitated by rising sea temperatures alterations marine ecosystems, which enable invasive exploit new outcompete native fauna. The movement towards higher latitudes represents threat, with potential severe impacts on biodiversity functionality ecosystems. highlights urgent need proactive strategies monitor manage lionfish, aiming mitigate substantial risks associated dominance environments.

An Optimized Probe‐Based qPCR Assay for the Detection and Monitoring of the Invasive Lionfish (Pterois volitans) in the Atlantic

Environmental DNA, Год журнала: 2025, Номер 7(2)

Опубликована: Март 1, 2025

ABSTRACT The Indo‐Pacific lionfish, Pterois volitans , is an invasive species in the western Atlantic. Since its introduction to Florida early 1980s, populations have surged with lionfish now found from North Carolina Venezuela. As their range expands, these generalist predators threaten native fauna, and while they are primarily a marine species, tolerance for low salinity conditions may allow them expand into sensitive estuarine habitats undetected. Traditional approaches tracking such as direct observation or trapping impractical over large spatial scales, making environmental DNA (eDNA) attractive alternative. Molecular assays, those employing quantitative polymerase chain reaction (qPCR), amplify copy number fragments samples increasingly employed complement traditional methods detection of species. Currently, there one published PCR assay eDNA. However, specificity this unverified, critical performance parameters limit (LOD) quantification (LOQ) not been established. Here we evaluate efficacy show that it likely result false negatives alternative, developed new TaqMan probe‐based qPCR species‐specific P. highly LOD 12 copies per LOQ 598 reaction. While our does closely related miles which was also introduced Atlantic, prevalence population means effective most monitoring purposes. We conclude robust method can be any habitat, offering opportunities controlling spread lionfish.
