“…These items have not been assigned to a source category, so perhaps the actual contribution of this source was higher. Shoes and sandals, clearly sourced household or leisure, are known to be able to float over large distances and have already been reported as rafting vectors [ 44 , 77 – 79 ].…”

“…For particular items, macroscopic attached biota has been reported. Examples are lines, ropes, nets and bait pots [ 38 – 40 ], aquaculture and other buoys [ 39 , 41 ], plastic packaging bands used in Antarctic bases and fishing boats [ 42 ], virgin plastic pellets [ 43 ], glass bottles [ 39 ], a gas cylinder reported above [ 21 ], a plastic spool [ 40 ], and tennis shoes and slippers [ 44 ], amongst others. Those reports might point to a higher contribution of litter items originated from sea-based activities such as aquaculture and fisheries.…”

“…Rafting on marine litter has been suggested to be involved in regional dispersal of several invertebrates [ 23 , 45 , 46 ]. For example, juveniles of the bivalve Pinctada imbricata and adults of Isognomon bicolor , which are considered invasive in Brazil, were found attached to anthropogenic litter for the first time at the Uruguayan coast, where they are regarded as potentially invasive as well [ 38 , 44 ]. In the Spanish part of the Bay of Biscay, several alien invasive species are registered [ 47 ], some of which are already known to attach to floating anthropogenic litter in other regions [ 16 ].…”

Anthropogenic marine litter composition in coastal areas may be a predictor of potentially invasive rafting fauna

Anthropogenic plastic pollution is a global problem. In the marine environment, one of its less studied effects is the transport of attached biota, which might lead to introductions of non-native species in new areas or aid in habitat expansions of invasive species. The goal of the present work was to assess if the material composition of beached anthropogenic litter is indicative of the rafting fauna in a coastal area and could thus be used as a simple and cost-efficient tool for risk assessment in the future. Beached anthropogenic litter and attached biota along the 200 km coastline of Asturias, central Bay of Biscay, Spain, were analysed. The macrobiotic community attached to fouled litter items was identified using genetic barcoding combined with visual taxonomic analysis, and compared between hard plastics, foams, other plastics and non-plastic items. On the other hand, the material composition of beached litter was analysed in a standardized area on each beach. From these two datasets, the expected frequency of several rafting taxa was calculated for the coastal area and compared to the actually observed frequencies. The results showed that plastics were the most abundant type of beached litter. Litter accumulation was likely driven by coastal sources (industry, ports) and river/sewage inputs and transported by near-shore currents. Rafting vectors were almost exclusively made up of plastics and could mainly be attributed to fishing activity and leisure/ household. We identified a variety of rafting biota, including species of goose barnacles, acorn barnacles, bivalves, gastropods, polychaetes and bryozoan, and hydrozoan colonies attached to stranded litter. Several of these species were non-native and invasive, such as the giant Pacific oyster (Crassostrea gigas) and the Australian barnacle (Austrominius modestus). The composition of attached fauna varied strongly between litter items of different materials. Plastics, except for foam, had a much more diverse attached community than non-plastic materials. The predicted frequency of several taxa attached to beached litter significantly correlated with the actually observed frequencies. Therefore we suggest that the composition of stranded litter on a beach or an area could allow for predictions about the corresponding attached biotic community, including invasive species.

Background: The introduction of alien species in a system affecting native species due to competition for food and space. The purse oyster Isognomon bicolor (Bivalvia, Pteriidae), a potential exotic invader, presents gaps in its distribution and ecology knowledge in Brazilian coast. For this reason, our objective was to investigate the occurrence of this oyster on pipeline monobuoys in Rio Grande do Sul, southern Brazil. Specimens were collected monthly during surveys carried out from March 2010 to June 2011 at the Tramandaí Beach, along two pipeline monobuoys, MN-601 and MN-602, randomly from the depths of three and 22 m. Results: We found I. bicolor dwelling on artificial hard substrates present in the Rio Grande do Sul coast, Brazil. This Caribbean bivalve was accidentally introduced to the Brazilian coast by ballast water from ships and, until now; it had not been recorded on the coast of Rio Grande do Sul state, which is under subtropical conditions. Conclusions: The occurrence of I. bicolor in the faunistic surveys accomplished in the Rio Grande do Sul coast represents the first documented record for this species in this region. As this species is a potential exotic invader, with a high dispersal capacity, control measures must be employed to prevent its spread.
