Native European crayfish conservation was triggered by invasion of plague disease agent, Aphanomyces astaci , starting 1860s in Northern Italy. Resulting epidemics quickly spread over Continental Europe, then to Finland, Sweden and finally, after running amok around A. discovered also Iberian Peninsula, Norway, Ireland, United Kingdom 1970s 1980s. By that time significant proportion native stocks had been lost, while were still recorded, industrialization waterways construction causing damage remaining stocks. While alien introductions, at least Faxonius limosus already gave rise first wave late 19th century, later 1960s it decided introductions Pacifastacus leniusculus should be initiated replace populations. Decisions based on presumed advantages for fishery, suitable habitat requirements supposed immunity against . Furthermore, species sidelined focus shifted toward stocking routine consumption. Alien resulted repeated waves among It soon North American origin were, as suspected, permanent reservoirs some those losing their resistance selected strains struggled aquatic ecosystems. In this article, we introduce numerous motives behind grand mistake introducing Europe promoting instead focusing species. We outline how false economical, biological ecologic assumptions used justify a hasty introduction crayfish, which has further devastated permanently changed ecosystems, both with disastrous consequences. Lesson learnt is science-based warnings about ecosystems must taken utmost caution. Protection core issue, not commercial activities. Finally, summarize main threats actions needed protect freshwater fauna Europe.

Conceptual and ethical considerations in invasion science

BioScience, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 21, 2025

Abstract Invasion science addresses interconnected ecological, economic, and social challenges posed by the introduction of nonnative species. Therefore, invasion scientists have to consider reconcile interdisciplinary needs while addressing potential implications their findings. Navigating diverse disciplines, including environmental sciences, ecology, economics, humanities, seek arrive at informed decisions on risk, impact, management. Individual biases, uncertainties, systemic pressures influence ability maintain objectivity resist that might otherwise distort findings or applications. In present commentary, we examine conceptual ethical dilemmas within field science, particularly reputational risks discipline perpetuating its own relevance framing invasions as insurmountable challenges. discussion, highlight how incentive structures, biased assessments framing, conflicts interest may compromise discipline's integrity.

The Green Wave: reviewing the environmental impacts of the invasive European green crab (Carcinus maenas) and potential management approaches

Environmental Reviews, Journal Year: 2022, Volume and Issue: 30(2), P. 306 - 322

Published: Jan. 14, 2022

The European green crab (Carcinus maenas), native to northwestern Europe and Africa, is among the top 100 most damaging invasive species globally. In some regions, including Atlantic coast of North America, C. maenas has caused long-term degradation eelgrass habitats bivalve, crab, finfish populations, while other areas are near beginning invasion cycle. Owing high persistence reproductive potential local regional mitigation efforts no longer strive for extirpation instead focus on population control. Long-term monitoring rapid response protocols can facilitate early detection introductions that critical inform management decisions related control or extirpation. Once detected, area managers will need decide actions, whether what measures be implemented, if might prevented extirpated, reduction achieve functional eradication achievable. immense operational demands likely required extirpate combined with limited resources removal, it unlikely any single government, conservation, (or) academic organization would positioned adequately populations in areas, highlighting importance collaborative efforts. Community-based monitoring, emerging methods such as environmental DNA (eDNA) may help expand spatial temporal extent facilitating removal maenas. While several programs have succeeded reducing their our knowledge, program yet successfully extirpated invader, cost unsustainable over long-term. An alternative approach eradication, whereby reduced below threshold levels ecosystem impacts minimized.

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.

The need of centralized coordination to counter biological invasions in the European Union

Environmental Sciences Europe, Journal Year: 2024, Volume and Issue: 36(1)

Published: July 8, 2024

Abstract Non-native species monitoring faces global challenges due to resource disparities, hindering effective implementation. Current strategies are fragmented and resource-dependent, inadequately addressing non-native dynamics subjected reporting biases, being further ridiculed by political borders. To overcome these challenges, a paradigm shift towards targeted, large-scale is crucial, requiring standardized protocols advanced technologies like environmental DNA analysis, orchestrated, applied—and enforced—following international collaboration. Despite existing efforts, networks, laws, even larger entities the European Union suffer from lack of information exchange as well economic, political, socio-cultural differences among member status, ultimately hampering united efforts against threat posed species. The absence comprehensive central hub authority, guided scientific input at same time empowered institution, emerges compelling solution. potential drawbacks, this possibly bridging gaps in approach, could coordinate standardize reporting, allocate resources, advocate increased funding. Considering rising introduction rates accelerating impacts species, creating centralized institution becomes imperative for enhancing management foster collaborative response threats.
