“…However, it can also have intrinsic economic value (Carmichael et al 2000, Gupta et al 2012). In the case of the Garopaba bloom, the dominant species A. uruguayense may have a high concentration of accessory photosynthetic pigments, phycocyanin, and phycoerythrin (Martins 2013). In addition, this species has high protein content (Barbarino and Lourenço 2005).…”

Blooms of macroalgae have grown over the planet in recent decades as a possible result of eutrophication of coastal waters. Visually, a bloom forming can be identified by dominant presence of an organism at the expense of others. In mid-January 2014, a forming bloom of red algae was detected on the beach of Garopaba, Santa Catarina State, Brazil. This aroused the interest of tourists and locals as well as the scientific community. Thus, the objective of this study was to characterize and quantify the photosynthetic floating organisms contributing to this phenomenon. In addition, we qualitatively compared algal composition of the bloom to those deposited in the post-beach area and the adjacent rocky shore community. Five sampling points in random patches of floating material were defined. At each point, five replicates were taken with a cube of 32,768 cm 3 , resulting in a total of 25 samples. Samples were collected in the inner area enclosed by a PVC quadrate of about 900 cm² from the shore and the specimens found in post-beach zone (wrack). Twenty-four taxa of macroalgae were found in the bloom, with Aglaothamnion uruguayense as the dominance one. Ten taxa were found on shore. Only four taxa were found in the post-beach area. The biomass estimated for A. uruguayense in the floating material was 8.35 tons with an estimated area of 52,770 m 2 . It is possible that this huge biomass value of the bloom is related to the local nutrient intake, and our results reinforce the necessity of coastal integrative management initiatives.

“…In addition, this species has high protein content (Barbarino and Lourenço 2005). Therefore, it is possible to use it as a food supplement (Martins 2013). Silva (2008) has suggested that the primary potential of these pigment molecules is that they can be used as natural dyes.…”

“…A comparação com dados pretéritos apontou diferenças entre os dados encontrados por Berchez (1985) com os esplanados aqui, corroborando com a hipótese de que encontraríamos diferenças significativas acerca da comunidade investigada nos locais denominados A1 e PD, informando ainda que uma alga pouco relatada anteriormente (A. uruguayense) é uma das mais representativas atualmente, sendo apontada por outros estudos como organismo com potencial biotecnológico (MARTINS et al, 2018) e para utilização como suplemento alimentar (LOURENÇO et al, 2002;BARBARINO & LOURENÇO, 2005;MARTINS, 2013). Além disso, apresentou queda na cobertura de P. capillacea, que pode corresponder à uma maior produtividade e papel ecológico (FERREIRA et al, 2001) quando comparada a A. uruguayense.…”
