Invasive non-native freshwater fishes have long been recognized as a threat to biodiversity conservation and management.Non-native with high risk of becoming invasive can be identified using screening tools.Here, we used the Aquatic Species Invasiveness Screening Kit (AS-ISK) identify invasion in Yunnan Province, China.AS-ISK scores were calibrated distinguish between species low-to-medium risks invasiveness.Risk threshold was 17.25 for BRA (Basic Risk Assessment) BRA+CCA (BRA+ Climate Change Province.Based on scores, 21 37 screened classified risk, 13 medium 3 low risk.Based 22 12 risk.For both BRA+CCA, highest-scoring Hypostomus plecostomus, Oreochromis aureus, mossambicus niloticus.This study reliably assessed fish Province priority prevention control, providing information targeted monitoring management decisions region.

Management of non-indigenous species in Macaronesia: Misconceptions and alerts to decision-makers

Marine Pollution Bulletin, Год журнала: 2024, Номер 204, С. 116506 - 116506

Human-induced pressures have led to substantial changes in marine ecosystems worldwide, with the introduction of non-indigenous species (NIS) emerging as a significant threat ecological, economic, and social aspects. The Macaronesian islands, comprising Azores, Madeira, Canary Islands, Cabo Verde archipelagos, are regions where regional economy is dependent on resources (e.g., traffic, ecotourism fisheries). Despite their importance, concerted efforts manage biological invasions Macaronesia been scarce. In this context, current study aims contribute much-needed debate biosecurity measures unique insular ecosystem prevent mitigate impact NIS. By adhering Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) criteria, work validated analyzed 260 documents providing insights into management NIS until 2022. These revealed presence 29 Invasive Alien Species (IAS), most which misconceptions regarding terminology. Most studies focused stages early detection, rapid response, eradication across archipelagos. had comparatively fewer studies. common techniques include monitoring/sampling, literature reviews, taxonomic reviews. pathways were mainly attributed transport (stowaway) unaided migration, ship fouling, ballast water, rafting, ocean currents, tropicalization being also identified contributors. This systematic review highlights establish robust protocols emphasizes urgent need safeguard region's well-being.

Socio-economic impacts of the recent bio-invasion of Callinectus sapidus on small-scale artisanal fishing in southern Italy and Portugal

Frontiers in Marine Science, Год журнала: 2024, Номер 11

Опубликована: Сен. 9, 2024

Introduction The recent and growing bio-invasion of the Callinectes sapidus (known as blue crab) is causing damages in European aquatic ecosystems, affecting livelihoods fishermen. In this context, study explores socio-economic impacts on small-scale artisanal fishermen Apulia (southern Italy) Algarve Portugal) regions, analyzing their perceptions highlighting repercussions livelihoods. Methods For purpose, we carried out a field survey with representative based “Socio-economic Impact Classification Alien Taxa” (SEICAT) approach by means an “Exploratory Factor Analysis” (EFA), “Hierarchical Analysis K-means Cluster Analysis”. Results discussion findings reveal that two areas, Algarve, exhibit markedly different impact crab invasion well-being activity Apulia, has led to extensive damage fishing nets, physical harm, decline other commercial species, reduced catch quantities, increased working hours, higher costs, lower incomes. Conversely, while net less severe, primary concerns are income. Consequently, research provides empirical basis for adoption management measures interventions mitigate socioeconomic community local economy, thereby contributing both individuals marine ecosystem.

Spoiled for Choice during Cold Season? Habitat Use and Potential Impacts of the Invasive Silurus glanis L. in a Deep, Large, and Oligotrophic Lake (Lake Maggiore, North Italy)

Water, Год журнала: 2021, Номер 13(18), С. 2549 - 2549

The ecological features of invasive alien species are crucial for their effective management. However, they often lacking in newly invaded ecosystems. This is the case European catfish Silurus glanis L. Lake Maggiore, where present since 1990, but no scientific information available on its ecology. To start filling this knowledge gap, 236 (67 cm to 150 total length) were collected, measured, and dissected stomach content analyses from three localities two habitats (littoral vs. pelagic) late autumn/early winter. NPUE BPUE (individuals (N) biomass (B, grams) per unit effort (m2), respectively) generally higher littoral (NPUE > 0.01; 96) than pelagic < 0.009; 114), had, average, larger sizes habitats. Overall, 581 individual prey items recorded, belonging 12 taxa. Pelagic specialized diet exclusively fish (coregonids, shad, roach), whilst was more variable dominated by crayfish, perch, roach. These results highlighted first time interaction with lake’s food web, thus possible consequences discussed, including potential contrasting role S. may have fishery.
