“…In many localities, Tubstraea spp. have been observed to grow on all kinds of artificial substrate, such as concrete (Ho et al, 2017) and plastics (Hoeksema and Hermanto, 2018;Valderrama Ballesteros et al, 2018;Faria and Kitahara, 2020), and in particular as invasive species on metal structures, such as ship hulls (Boschma, 1953), shipwrecks (Hoeksema et al, 2019b;Soares et al, 2020), pontoons (López et al, 2019;Tanasovici et al, 2020), and oil platforms (Brito et al, 2017;Creed et al, 2017). At Koh Tao, high abundances of Tubastraea micranthus were only found on the pinnacles, where they showed high abundances during the present study and earlier (Fig.…”

“…Recently, Roepke et al [40] studied the toxicity of DCOIT (free and encapsulated forms in cerium oxide nanoparticles) and observed that the antifouling inhibited algal fouling but did not affect coral larval settlement. Still, the lack of effects even at the highest concentrations (i.e., at magnitudes of milligrams per liter) shows that T. coccinea is highly tolerant to AF biocides tested, another advantage to its spread along the Brazilian coast, including at seaports [41] and recreational marinas [42], where the concentration of antifouling biocides might be high. In this sense, the application of AF biocides would favor T. coccinea to the detriment of other species, and this may enhance the problem in areas where the sun coral is an invasive species, such as the Brazilian coast.…”

Biocides used in antifouling (AF) paints, such as 4,5-dichlorine-2-n-octyl-4-isothiazole-3-one (DCOIT), can gradually leach into the environment. Some AF compounds can persist in the marine environment and cause harmful effects on non-target organisms. Nanoengineered materials, such as mesoporous silica nanocapsules (SiNC) containing AF compounds, have been developed to control their release rate and reduce their toxicity to aquatic organisms. This study aimed to evaluate the acute toxicity of new nanoengineered materials, SiNC-DCOIT and a silver-coated form (SiNC-DCOIT-Ag), as well as the free form of DCOIT and empty nanocapsules (SiNC), on the sun coral Tubastraea coccinea. T. coccinea is an invasive species and can be an alternative test organism for evaluating the risks to native species, as most native corals are currently threatened. The colonies were collected from the Alcatrazes Archipelago, SP, Brazil, and acclimatized to laboratory conditions. They were exposed for 96h to different concentrations of the tested substances: 3.33, 10, 33, and 100 µg L-1 of free DCOIT; 500, 1000, 2000, and 4000 µg L-1 of SiNC; and 74.1, 222.2, 666.7, and 2000 µg L-1 of SiNC-DCOIT and SiNC-DCOIT-Ag. The test chambers consisted of 500 mL flasks containing the test solutions, and the tests were maintained under constant aeration, constant temperature of 23 ± 2°C, and photoperiod of 12h:12h (light/dark). At the end of the experiments, no lethal effect was observed; however, some sublethal effects were noticeable, such as the exposure of the skeleton in most of the concentrations and replicates, except for the controls, and embrittlement at higher concentrations. Adults of T. coccinea were considered little sensitive to the tested substances. This resistance may indicate a greater capacity for proliferation of the species, which is favored in substrates containing antifouling paints, to the detriment of the native species.

Biocides used in antifouling (AF) paints, such as 4,5-dichlorine-2-n-octyl-4-isothiazole-3-one (DCOIT), can gradually leach into the environment. Some AF compounds can persist in the marine environment and cause harmful effects to non-target organisms.
