“…Marine litter may thus have facilitated its spread in Indian waters. Our findings indicate that the growing presence of plastic litter may increase the probability of introducing non-indigenous and invasive species into Indian waters, potentially generating a negative impact on the ecological characteristics of the invaded habitat as already happened (Rech et al, 2016;Miralles et al, 2018;Lins and Rocha, 2022). The phyla recorded here include several invasive species previously documented on marine litter (Garcia-Vazquez et al, 2018;Miralles et al, 2018;Rech et al, 2018b;Lins and Rocha, 2022).…”

“…A comparative study to understand the relative importance of port and aquaculture farm populations as sources of propagules would be necessary. But the presence of established reproductive populations in aquaculture farms ( Lins & Rocha, 2022 ) near ports calls for an integrated approach to informing decision-making procedures for expanding or establishing aquaculture farms. Stakeholder perceptions may vary about the importance of an ecosystem approach when locating aquaculture parks ( Vianna & Filho, 2018 ), so these results should be made clear to them.…”

“…Eight invasive NIMS recognized to be spread and abundant in aquaculture facilities in Santa Catarina ( Lins & Rocha, 2022 ) were targeted in the present study: the ascidians Aplidium accarense (Millar, 1953), Botrylloides giganteus (Pérès, 1949), Didemnum perlucidum Monniot F., 1983 and Styela plicata (Lesueur, 1823), the bryozoans Schizoporella errata (Waters, 1878) and Watersipora subtorquata (d’Orbigny, 1852), the barnacle Megabalanus coccopoma (Darwin, 1854) and the bivalve Mytilus galloprovincialis Lamarck, 1819. These species are worldwide hitchhikers that have been unintentionally introduced to Brazil (although it is not clear if A. accarense is a regional or international invader).…”

“…The region is also notable for having the second largest concentration of shipyards and two of the nation’s largest ports, to the north (Port of Itajaí) and to the south (Port of Imbituba) of the farming areas ( Agência Nacional de Transportes Aquaviários (ANTAQ), 2021 ), which increases the risks of unintentional regional and international transport of fouling species. Non-indigenous invasive species are already prevalent fouling species in marine aquaculture facilities ( Rocha et al, 2009 ; Lins & Rocha, 2022 ). Therefore, risk assessment of the impact of shellfish farming on the regional biodiversity should also consider fouling NIMS, their range expansion, and predictions of future movements of those species that are already known to be problematic in other regions.…”

“…This suggests that the NIMS in aquaculture facilities in Santa Catarina have many opportunities for transport (strong propagule pressure) along the coast. In this study we focused on eight invasive NIMS established in aquaculture facilities at Santa Catarina ( Lins & Rocha, 2022 ) to understand their potential to be introduced and invasive in other places in the country, based on current domestic shipping trade between ports in Santa Catarina and other states, using species suitability models to address current and future environmental suitability.…”

Non-indigenous species tend to colonize aquaculture installations, especially when they are near international ports. In addition to the local environmental hazard that colonizing non-indigenous species pose, they can also take advantage of local transport opportunities to spread elsewhere. In this study, we examined the risk of the spread of eight invasive fouling species that are found in mussel farms in southern Brazil. We used ensemble niche models based on worldwide occurrences of these species, and environmental variables (ocean temperature and salinity) to predict suitable areas for each species with three algorithms (Maxent, Random Forest, and Support Vector Machine). As a proxy for propagule pressure, we used the tonnage transported by container ships from Santa Catarina (the main mariculture region) that travel to other Brazilian ports. We found that ports in the tropical states of Pernambuco, Ceará, and Bahia received the largest tonnage, although far from Santa Catarina and in a different ecoregion. The ascidians Aplidium accarense and Didemnum perlucidum are known from Bahia, with a high risk of invasion in the other states. The bryozoan Watersipora subtorquata also has a high risk of establishment in Pernambuco, while the ascidian Botrylloides giganteus has a medium risk in Bahia. Paraná, a state in the same ecoregion as Santa Catarina is likely to be invaded by all species. A second state in this region, Rio Grande do Sul, is vulnerable to A. accarense, the barnacle Megabalanus coccopoma, and the mussel Mytilus galloprovincialis. Climate change is changing species latitudinal distributions and most species will gain rather than lose area in near future (by 2050). As an ideal habitat for fouling organisms and invasive species, aquaculture farms can increase propagule pressure and thus the probability that species will expand their distributions, especially if they are close to ports. Therefore, an integrated approach of the risks of both aquaculture and nautical transport equipment present in a region is necessary to better inform decision-making procedures aiming at the expansion or establishment of new aquaculture farms. The risk maps provided will allow authorities and regional stakeholders to prioritize areas of concern for mitigating the present and future spread of fouling species.
