Influence of antifouling paint on freshwater invertebrates (Mytilidae, Chironomidae and Naididae): density, richness and composition

Abstract

We conducted a study about invertebrates on artificial substrates with different antifouling paints in order to answer the following questions: 1) is there lower accumulation of organic matter on substrates with antifouling paints, 2) is invertebrate colonization influenced by the release of biocides from antifouling paints, 3) is the colonization of aquatic invertebrates positively influenced by the material accumulated upon the substrate surface and 4) is the assemblage composition of invertebrates similar among the different antifouling paints? To answer these questions, four structures were installed in the Baía River in February 1 st , 2007. Each structure was composed of 7 wood boards: 5 boards painted with each type of antifouling paints (T1, T2, T3, T4 and T5), one painted only with the primer (Pr) and the other without any paint (Cn). After 365 days, we observed a greater accumulation of organic matter in the substrates with T2 and T3 paint coatings. Limnoperna fortunei was recorded in all tested paints, with higher densities in the control, primer, T2 and T3. The colonization of Chironomidae and Naididae on the substrate was positively influenced by L. fortunei density. The non-metric multidimensional scaling (NMDS) of the invertebrate community provided evidence of the clear distinction of invertebrate assemblages among the paints. Paints T2 and T3 were the most similar to the control and primer. Our results suggest that antifouling paints applied on substrates hinder invertebrate colonization by decreasing the density and richness of invertebrates.Keywords: colonization, biofouling, Limnoperna fortunei. Influência de revestimentos antiincrustantes em invertebrados aquáticos (Mytilidae, Chironomidae and Naididae): densidade, riqueza e composição ResumoO estudo dos invertebrados em substrato artificial com diferentes revestimentos antiincrustantes foi realizado com o intuito de responder as seguintes questões: 1) Há menor acumulação de material orgânico nos substratos com revestimentos antiincrustantes? 2) A colonização de invertebrados é afetada pela liberação de biocidas dos revestimentos antiincrustantes? 3) A colonização dos invertebrados aquáticos é facilitada por material acumulado sobre a superfície do substrato? 4) A composição da assembléia é similar entre os diferentes revestimentos? Para realização deste estudo, quatro estruturas foram instaladas em 01 de fevereiro de 2007 no rio Baía. Em cada estrutura foram colocadas sete placas de madeira: cinco placas com aplicação de um tipo de revestimentos antiincrustantes (T1, T2, T3, T4 e T5), uma placa apenas com a aplicação do primer (Pr) e a outra placa permaneceu sem aplicação de nenhum revestimento (Cn). Ao final dos 365 dias em que os substratos ficaram submersos observou-se maior acumulação de material orgânico nos substratos dos revestimentos T2 e T3. Limnoperna fortunei foi registrada em todos os revestimentos testados, com maiores densidades encontradas no controle, primer, T2 e T3. A colonização de Chironomidae e Naididae sobre os...

Pinturas antiincrustantes derivadas de plantas terrestres una solución segura para el ambiente en el control de la bioincrustación

“…Sin embargo, todas estas estrategias no son eficientes o causan una alta mortalidad de larvas y deformación en los sobrevivientes (Breitig, 1965;Katsuyama, et al, 2005;Santos, et al, 2012). Otra estrategia es el control químico utilizando superficies pintadas con antiincrustantes (Fujita, et al, 2015). Aunque se han desarrollado diversas pinturas antiincrustantes para abordar el problema de la bioincrustación (Telegdi, et al, 2016), una alternativa antiincrustante ecológicamente segura y eficiente aún no está disponible en el mercado (Konstantinou y Albanis, 2004;Agostini, et al, 2018).…”

Antifouling-Bacterial Potentials of Kenikir (Cosmos caudatus) and Bandotan (Ageratum conyzoides) Leaf Extracts in Freshwater Environment

“…Biofouling is the accumulation or growth of unwanted organisms, plants, or animals on the surface of an object (natural or artificial) submerged in water such as bacteria, viruses, fungi, microalgae, protozoa, and meroplankton (Agostini et al, 2019;Fujita et al, 2015;Marhaeni, 2012). This occurs due to the adsorption of organic molecules on the surface of a hard substrate submerged in water, followed by bacterial colonization which produces Extracellular Polymer Substance (EPS) which forms biofilms (Agostini et al, 2019;Aykin et al, 2019).…”
