“…In contrast to other invasive species, where shelter use of the invasive is unchanged in the presence of native species [42,111], we found that lionfish reduced their shelter use in the presence of lobsters or Diadema. Our findings lend support to anecdotal evidence that reefs with high urchin densities support few lionfish [57], potentially because urchins occupy all available shelters. In our lionfish-lobster together trials we found an effect of prior residency, where lionfish were less likely to dominate a shelter if a lobster occupied the shelter first.…”

“…This could lead to lionfish displacing lobsters and Diadema from shelters, thus exposing them to greater predation risk. Similar shelter preferences between lionfish, spiny lobsters and Diadema have been suggested [ 57 ], and shelter use interactions between lionfish and lobsters are believed to occur. Lionfish are highly abundant by-catch species in lobster traps [ 58 ] and the presence of lionfish is associated with lower lobster abundance in both traps [ 59 ] and condos (non-enclosed shelter traps; [ 60 , 61 ]).…”

“…For lobsters and Diadema , higher complexity habitat provides protection from predation [ 47 , 48 ]. The preference of lionfish for complex habitat applies across the invaded western Atlantic range (e.g [ 57 , 96 , 97 ]). In areas with frequent culling, lionfish use complex habitat to escape culling by humans [ 38 ].…”

Shelter use interactions of invasive lionfish with commercially and ecologically important native invertebrates on Caribbean coral reefs

Indo-Pacific lionfish have become invasive throughout the western Atlantic. Their predatory effects have been the focus of much research and are suggested to cause declines in native fish abundance and diversity across the invaded range. However, little is known about their non-consumptive effects, or their effects on invertebrates. Lionfish use shelters on the reef, thus there is potential for competition with other shelter-dwelling organisms. We demonstrate similar habitat associations between invasive lionfish, native spiny lobsters (Panulirus argus) and native long-spined sea urchins (Diadema antillarum), indicating the potential for competition. We then used a laboratory experiment to compare activity and shelter use of each species when alone and when lionfish were paired with each native species. Spiny lobsters increased their activity but did not change their shelter use in the presence of a lionfish, whilst long-spined sea urchins changed neither their activity nor shelter use. However, lionfish reduced their shelter use in the presence of spiny lobsters and long-spined sea urchins. This study highlights the importance not only of testing for the non-consumptive effects of invasive species, but also exploring whether native species exert non-consumptive effects on the invasive.

“…The presence of lionfish may also deter native species, as suggested by higher lionfish and lower native species recruitment in shorter soak times and the opposite with longer soak times. Higher lionfish recruitment and catch from single trap deployments disproved our hypothesis that paired deployments could synergistically recruit more lionfish, given lionfish are often found in groups [55] and aggregating behavior is driven by broad-scale habitat complexity [56,57]. Counterintuitively, our results indicated that lionfish density on the adjacent artificial reef was not a significant predictor of lionfish recruitment nor catch.…”

18Spearfishing is currently the primary approach for removing invasive Indo-Pacific lionfish 19 (Pterois volitans/miles complex) to mitigate their impacts to western Atlantic marine ecosystems. 20 However, a substantial portion of lionfish spawning biomass is beyond the depth limits of SCUBA. 21 Innovative technologies may offer an alternative means to target lionfish and allow for the 22 development of a deepwater lionfish trap fishery, but the removal efficiency and potential 23 environmental impacts of traps have not been evaluated. We tested a collapsible non-containment 24 trap (the 'Gittings trap') near artificial reefs in the northern Gulf of Mexico. A total of 327 lionfish 25 and 28 native fishes (4 of which regulated species) recruited to traps (i.e., number of fish observed 26 within the trap footprint) during 82 trap sets, catching 144 lionfish and 29 native species. Lionfish 27 recruitment was highest for single (versus paired) traps deployed <15 m from reefs with a 1-day 28 soak time, for which mean lionfish and native species recruitment per trap were approximately 5 29 and 0.1, respectively. Gittings traps selected for larger lionfish (mean size 277 mm total length) 30 compared to spearfishing (mean size 258 mm). Community impacts from Gittings traps appeared 31 minimal given recruitment patterns and catch rates were >10X higher for lionfish versus native 32 fishes. Gittings traps did not move on the bottom during two major storm events; however, further 33 testing will be necessary to test trap movement with surface buoys. Additional research should also 34 focus on design and operational modifications to improve Gittings trap deployment success (68% 35 successfully opened on the seabed) and reduce lionfish escapement (56% escaped from traps upon 36 retrieval). While removal efficiency for lionfish (12-24%) was far below that of spearfishing, 37 study results demonstrate Gittings traps are suitable for future testing on deepwater natural reefs, 38 which constitute >90% of the region's reef habitat. 3 of 23 39 Introduction 40 Invasive Indo-Pacific lionfish (Pterois volitans/miles complex, hereafter "lionfish") are 41 now well established in the western Atlantic, including the Caribbean Sea and Gulf of Mexico [1] 42 and have recently invaded the Mediterranean Sea [2]. Lionfish occupy a wide diversity of invaded 43 marine habitats, including coral reefs, subtropical artificial and natural reefs [3], seagrass beds [4], 44 mangroves [5], estuaries [6], mesophotic reefs [7-9], and upper continental slope reefs [10]. High 45 population densities of lionfish [3,11] have caused reductions in native reef fish abundances 46 [12,13], altered marine communities [14,15], and likely exacerbate current stressors on marine 47 systems [16,17]. As invasive lionfish populations do not appear to be controlled by native 48 predators [18-20], reducing lionfish biomass a top priority for marine resource managers [21,22]. 49 The current capacity to remove lionfish is primarily by spearfishing [21,23]. However, 50 lionfish...

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