Performance of Azolla caroliniana Willd. and Salvinia auriculata Aubl. on fish farming effluent

The increasing release of untreated fish farming effluents into water courses that flow to the Pantanal wetlands in Mato Grosso (Brazil) may drive this ecosystem to eutrophication. Therefore, the growth of Azolla caroliniana Willd. and Salvinia auriculata Aubl. in fish farming effluent and their eff...

Therefore, the growth of Azolla caroliniana Willd. and Salvinia auriculata Aubl. in fish farming effluent and their effect on its quality were evaluated for 48 days in a greenhouse. The results were compared to those obtained in a nutrient rich solution (Hoagland 1/2 medium). Azolla caroliniana showed lower relative growth rate in fish farming effluent (0.020 d-1) than in Hoagland 1/2 medium (0.029 d-1). However, S. auriculata grew slightly better in fish farming effluent (0.030 d-1) than in Hoagland 1/2 medium (0.025 d-1). The species apparently contributed to reduce nitrate and phosphate concentration in Hoagland 1/2 medium. However, in fish farming effluent, only electrical conductivity and pH were reduced by plants compared to the control without plants. Thus, A. caroliniana and S. auriculata show low potential for improving effluent quality. 2020-05-31T18:24:28Z 2020-05-31T18:24:28Z 2011 Artigo https://repositorio.inpa.gov.br/handle/1/16212 10.1590/S1519-69842011000100007 pt_BR Volume 71, Número 1, Pags. 37-45 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Revista Brasileira de Biologia
