“…They were also more effective for NIS. Outinen et al (2019) came to the same conclusions based on research conducted in the Archipelago Sea (Finland) between June and September in 2012. The effectiveness of shelter traps was also confirmed by studies conducted by Veldhuizen (2000), Fowler et al (2013) and Hewitt and McDonald (2013).…”

“…Similarly to Outinen et al (2019), our study indicates high sampling efficiency of artificial habitat collectors compared to baited traps. Admittedly, they require a long exposure and time-consuming analysis if many organisms are caught, but the effectiveness of the mobile epifauna collection (even with fewer deployments) favors their use in port monitoring.…”

The effectiveness of two artificial habitat collectors, crab condo (HC1) and habitat crate (HC2), providing a refuge for small mobile fauna, was tested along with two commercial baited traps, Chinese box trap (BT1) and Gee’s Minnow trap (BT2) recommended for only single deployments under a harmonized survey of the Baltic and the North-East Atlantic. Our objective was also to determine whether a multi-deployment of baited traps in the growing season increases the diversity and abundance of collected mobile epifauna. Nineteen species of benthic mobile epifauna, including six non-indigenous species (NIS), were collected between May and October 2014 using all tested types of traps in the Port of Gdynia (southern Baltic Sea). Crustaceans, represented by 16 taxa, constituted the group with the highest diversity and abundance. Our study showed that HC1 and HC2 are more effective gear than BT1 and BT2, as both species richness (including NIS) and abundance were higher. Furthermore, the double deployment of BT1 and BT2 increased the diversity and abundance of the captured fauna. The use of artificial habitat collectors as an additional method to the already recommended baited traps for mobile epifauna monitoring in ports should be considered and the number of baited trap deployments should be increased during the growing season.

“…Several methodologies for sampling fouling communities in port habitats have been developed over the years. Most common techniques include (i) Rapid Assessment Surveys-RAS (e.g., Cohen et al, 2005;Campbell et al, 2007;Olenin et al, 2007;Minchin, 2012;Lehtiniemi et al, 2015;Marchini et al, 2015;Gewing and Shenkar, 2017;Ulman et al, 2017); (ii) net-assisted scraping (e.g., Ferrario et al, 2017;Ulman et al, 2017;Tempesti et al, 2020), including quadrat scraping during snorkeling or scuba diving (e.g., Neves et al, 2007;Awad et al, 2014;Ulman et al, 2019b); and artificial substrate units (ASU), such as (iii) two-dimensional settlement panels (e.g., Relini, 1977;Canning-Clode et al, 2013;Dos Santos Schwan et al, 2016;Lezzi et al, 2017;Marasinghe et al, 2018;Carlton, 2019;Leclerc et al, 2019); and (iv) three-dimensional artificial habitat collectors (e.g., Fowler et al, 2013;Gestoso et al, 2019;Outinen et al, 2019;Holmes and Callaway, 2020;Obst et al, 2020;Ros et al, 2020). Any of the above methods involves both advantages and disadvantages, and their success or suitability depend on the aim of the study.…”

Monitoring Non-indigenous Species in Port Habitats: First Application of a Standardized North American Protocol in the Mediterranean Sea

et al. 2021

Baseline port monitoring for fouling communities is an essential tool to assess non-indigenous species (NIS) introduction and spread, but a standardized and coordinated method among Mediterranean and European countries has not yet been adopted. In this context, it is important to test monitoring protocols that allow for the collection of standardized and directly comparable data, replicated across time and space. Here, for the first time in the Mediterranean Sea, we tested a standardized protocol developed by the Smithsonian Environmental Research Center (SERC) and used now in several countries. The 3-year monitoring survey (2018–2020) was conducted in the Gulf of La Spezia (Ligurian Sea, Italy), with the deployment of a total of 50 PVC panels per year in five different sites (a commercial harbor, three marinas and a site in the proximity of a shellfish farm). A total of 79 taxa were identified, including 11 NIS, ranging from zero to seven NIS for each panel. In comparison with previous surveys, new NIS arrivals were observed in the Gulf of La Spezia: Botrylloides cf. niger, Branchiomma sp., Branchiomma luctuosum, Paraleucilla magna, and Watersipora arcuata. At the end of the 3-year monitoring, mean richness? and percent cover of NIS were measured, and both measures differed across the monitoring sites, with higher values in two marinas and in the commercial harbor. Among years, richness of NIS was relatively stable at each monitoring site. The structure of the fouling was influenced more by native and cryptogenic species than by NIS. Moreover, among the monitoring sites, the density of artificial structures was not a reliable predictor or proxy for local NIS abundance. This first application of the SERC method in the Mediterranean Sea, demonstrates both pros and cons, including the detection of new NIS reported here. Further direct comparisons with other NIS monitoring tools are recommended, and additional tests to assess its effectiveness in this biogeographical area are encouraged. A broader application of this and other standard methods across temporal and spatial scales in the Mediterranean basin should be implemented, providing critical data needed to assess changes in the structure of fouling communities.
