“…However, eradication in the marine environment may still be feasible when specific conditions are met (e.g. Bax et al 2002;Culver and Kuris 2000;Wotton et al 2004), and this is reflected in the result for Japanese sting winkle (Ocenebra inornata). We found no correlation between taxa and overall feasibility of eradication in our data; however, terrestrial vertebrates generally received moderate or higher scores for feasibility of eradication, which reflects experience from GB and elsewhere (Genovesi 2005;Robertson et al 2016).…”

“…The immediate initiation of organized, local removal efforts on Bonaire by training many (± 300) local divers for lionfish removal efforts has resulted in lowered lionfish biomass and density relative to unfished sites on the leeward side of the same island within 2 yr after the first lionfish was sighted. A rapid (local) response to reduce the abundance of invasive species is widely accepted as the most efficient methodology to reduce excessive growth of invasive populations (Culver & Kuris 2000, Secord 2003, Wotton et al 2004, Anderson 2005, and the present study shows that such local management interventions to reduce the local number of lionfish can be successful, as has been shown elsewhere in the Caribbean (Frazer et al 2012). That Bonaire has easily accessible reef sites along its entire leeward coast likely contributed to the success of local removal efforts.…”

“…In contrast to terrestrial invasions, experiences with and methods to deal with marine invasions are limited (Bax et al 2001, Secord 2003, and while some management efforts on land have been successful, relatively few marine invaders have been fully removed from their non-native range (Culver & Kuris 2000, Bax et al 2001, Secord 2003, Wotton et al 2004, Anderson 2005, Genovesi 2005. Full removal or control of marine invasives is complicated by the ability of marine invasives to disperse across large distances (e.g.…”

Lionfish Pterois volitans and P. miles have spread rapidly throughout the Caribbean Sea since 1985, where they negatively impact native fish communities and therefore are considered by some as the most damaging invasive species in the Caribbean to date. To combat further population growth and spread of lionfish and to protect native fish communities, various Caribbean islands have started control efforts. On Bonaire, a removal program based on volunteers using spear guns was started immediately after the first lionfish was sighted in 2009, and a similar program was started on neighboring Curaçao 2 yr later. To determine the effectiveness of these removal efforts, differences in the density and biomass of lionfish were compared between areas in which lionfish were directly targeted during removal efforts (i.e. 'fished' areas) on Bonaire and areas where they were not (i.e. 'unfished areas') on both Bonaire and Curaçao. Lionfish biomass in fished locations on Bonaire was 2.76-fold lower than in unfished areas on the same island and 4.14-fold lower than on unfished Curaçao. While removal efforts are effective at reducing the local number of lionfish, recruitment from unfished locations, such as those too deep for recreational diving and at dive sites that are difficult to access, will continuously offset the effects of removal efforts. Nevertheless, our results show that the immediate start and subsequent continuation of local removal efforts using volunteers is successful at significantly reducing the local density and biomass of invasive lionfish on small Caribbean islands.

P. volitans/miles were first sighted in the Atlantic region near the southeast coast of North America in 1985, where they had likely been released by aquarists (Semmens et al. 2004). From there, they first spread northward along the east coast of the USA and since 2004 also southward toward the Caribbean Sea, the Gulf of Mexico and the north coast of South America (Schofield 2009, 2010, Johnston & Purkis 2011, Frazer et al. 2012). In the Caribbean, lionfish have established themselves in a variety of marine habitats, including coral reefs, mangroves, sea grass beds, coastal estuaries and deep waters up to 300 m (Barbour et al. 2010, Biggs & Olden 2011, Jud et al. 2011.

“…This seaweed arrived in New Zealand around 1987 and has since spread throughout much of the South Island (Hay & Villouta 1993, Parsons 1995, Stuart 2004, Russell et al 2008, aided by multiple incursions (Uwai et al 2006). Once established, attempts at removing it have been mostly unsuccessful (Stuart 2004, Hewitt et al 2005, Forrest & Blakemore 2006, but see Wotton et al 2004), presumably because of its fast growth rate and high reproductive output (Hay & Villouta 1993, Dean & Hurd 2007, Casas et al 2008, Primo et al 2010. Undaria pinnatifida is very efficient at using nutrients for quick growth and has an opportunistic life history (Schiel & Foster 2006, Dean & Hurd 2007, Russell et al 2008.…”

ABSTRACT:The mechanisms by which non-indigenous species overcome resistance in native communities are not well understood but are fundamental to the ability of invaders to persist and spread once they reach alien shores. One of the most widespread invaders is the kelp Undaria pinnatifida. Here we test disturbance, competition and facilitation in its recruitment into intertidal algal communities in southern New Zealand. In field-based experiments, we manipulated native fucoid and U. pinnatifida canopies, as well as the abundance and type of understory turfing species, and provided various gap sizes in native communities. Undaria pinnatifida recruitment occurred almost exclusively on coralline turf and in the absence of canopies, both native and conspecific. Where the native fucoid canopy was removed, U. pinnatifida recruited into gaps of all sizes (5 × 5 cm, 25 × 25 cm, 50 × 50 cm), but the smallest gaps recovered their native canopy within several months and precluded further recruitment. Experimental manipulations of coralline turf showed that recruitment of U. pinnatifida was orders of magnitude greater where turf was present, regardless of the timing or sizes of clearances. Facilitation did not occur with other turfing species. Overall, native fucoids showed high resistance to invasion, but there was great facilitation by native coralline turf. Furthermore, as annual U. pinnatifida canopies disappear over summer, it is clear that coralline turf harbors the microscopic stages of U. pinnatifida that will form the following year's populations. As turfing species increase and persist following disturbances of native canopies worldwide, it can be expected that the recruitment dynamics of non-indigenous species will also change.
