| description | <p dir="ltr">The determination of the resilience of benthic assemblages is a capital issue for the off-shore aquaculture industry in its attempts to minimize environmental disturbances. Experimental studies are an important tool for the establishment of thresholds for macrofaunal assemblages inhabiting sandy seabeds. An experiment was conducted with three treatments (Control, 1x and 3x),in which organic load (fish pellets) was added (1x (10 g of fish pellets) and 3x (30 g)). A reduction in abundance of individuals and species richness was found as between the control and organic-enriched treatments. Significant changes in assemblage structure were also found, mainly due to the decrease of the sensitive tanaid Apseudes talpa in organically-enriched treatments. AMBI and M-AMBI indices were calculated and a decrease of ecological status was observed in treatment 3x.</p><p dir="ltr">A determinação da resiliência das assembleias bênticas é um assunto fundamental para a indústria da aquicultura de mar aberto como tentativa de minimizar as perturbações ambientais. Estudos experimentais são ferramenta importante para o estabelecimento das linhas de base para as comunidades do fundo oceânico. Nesse sentido, um experimento foi conduzido sob três tratamentos (controle, 1x e 3x), nos quais o aporte orgânico (pelotas fecais de peixes) foi adicionado nas quantidades de 1x (10 g de pelotas fecais) e de 3 vezes (30 g). Os resultados mostram que foi encontrada redução na abundância de indivíduos e também no número de espécies entre o controle e os tratamentos com enriquecimento orgânico. Mudanças significativas na estrutura das assembleias também foram encontradas, principalmente devido ao decréscimo do tanaidáceo sensível Apseudes talpa nos tratamento enriquecidos. Os índices AMBI e M-AMBI foram calculados e um decréscimo do status ecológico foi observado no tratamento 3x.</p><h2>Other Information</h2><p dir="ltr">Published in: Brazilian Journal of Oceanography<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" rel="nofollow" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1590/s1679-87592013000400003" target="_blank">https://dx.doi.org/10.1590/s1679-87592013000400003</a></p> |
