One-Health is an umbrella term that integrates the health of environment, humans and non-human animals. This approach applied here to elucidate impact non-native invasive species on aquaculture food security. Despite inherent biases against these species, a better understanding their characteristics allows for identification those greatest concern, minimizing risk shortages infectious diseases. review summarises positive negative impacts delineating specific areas they may impact. Additionally, this gives insight expertise stakeholders would need be included if "One-Health" were implemented by policymakers control species. Detailed examples illustrate consequences trophic dynamics, ecosystem health, water chemistry, human emphasizing importance managing them within multidimensional framework.

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.

Invasive species pose threats to either human health or inflict ecological and/or economic damage. The silver-cheeked toadfish ( Lagocephalus sceleratus ), a Lessepsian species, is one of the most harmful in Mediterranean Sea, because its potent neurotoxin, impacts on marine biodiversity, and increased costs labor they fishers.

Photogrammetric determination of movement speed of invasive Indo-Pacific lionfish in the Florida Keys

As a key determinant of how efficiently lionfish ( Pterois sp.) locate and capture prey, swimming speed plays crucial role in shaping the predator-prey interactions broader ecological dynamics within invaded ecosystems. Swimming on small temporal spatial scale is difficult to measure because need for precise measurements both distance duration behavior. Using photogrammetry by way stereo-camera setups ideal analyzing minutiae behaviors it can include benefits remote video traps coupled with movements three-dimensional space time. The primary objective this study was identify characterize behavior associated different movement speeds, then quantify small-scale speeds those behaviors. were classified under three observed behaviors: relaxed swimming, traverse striking at prey. differences between these primarily distinguished based body fin positioning, as well apparent intent motion if any evident. mean from stereoscopic camera footage 44.75 mm s −1 138.99 625.44 be used much habitat area may cover day, therefore amount prey that encountered predator.

Marine protected areas can increase the abundance of invasive lionfish (Pterois miles)

Conservation Science and Practice, Journal Year: 2024, Volume and Issue: 6(6)

Published: June 1, 2024

Abstract Marine protected areas (MPAs) can protect and restore marine biodiversity fisheries, but there are concerns that they may also benefit invasive species. The spatial temporal colonization of lionfish ( Pterois miles ) in the eastern Mediterranean was compared across zones with varying fishing restrictions (no fishing, recreational commercial only), stations where targeted removal events were conducted by volunteer SCUBA divers. Lionfish density no nearly double only, over four times greater than both allowed. increased depth, possibly due to easier human exploitation shallow waters (0–10 m) accessible spearfishers. Targeted removals divers decreased densities 60%, while without had a 200%–400% increase. Along management actions, natural ecological processes might drive within MPAs, speed which colonized fishery‐restricted zones, emphasized need for more sophisticated MPA strategy considers species impacts dynamics an ecosystem‐based approach.

Abstract Invasive alien species pose a great challenge in conservation ecology. Rapid establishment of common lionfish ( Pterois miles ) the eastern Mediterranean Sea and its ongoing westward expansion raises many questions about how to sustainably combat this invasion long term. Drawing on experiences from western Atlantic invasion, citizen scientists were engaged demonstrated efficiency long‐term coordinated removals for first time Sea. Findings reveal sustained participation interest throughout removal events that encourage organization future events. Removal Action Teams found effective at reducing numbers small (less than half hectare) areas high value, when repeated systematically. Single‐day derbies, operated greater spatial scales, succeeded 50% reduction abundance while removing most large (>30 cm) individuals an area after three consecutive Given recreational character such activities, are useful options management guided by competent authorities supported citizens, as they promote marine environmental awareness help develop sense stewardship among members public.

Here, we used thousands RAD seq genomic markers study population this invasion. While did not find reduction genetic diversity between source (Red Sea) invasive (Mediterranean) populations (i.e., bottleneck effects), found evidence structure within range Sea. We that loci are potentially under selection may play an important role success (in particular, genes involved osmoregulation fin spine sizes).
