Potential use of two subtropical mangrove species (Laguncularia racemosa and Rhizophora mangle) for nutrient removal in closed recirculating systems

Six silvofishery systems were constructed to estimate the potential use of mangrove seedlings for nutrient removal. Two systems did not contain seedlings (i.e., control treatment), while the remaining systems were divided into separate treatments using two mangrove species (Laguncularia racemosa and...

Two systems did not contain seedlings (i.e., control treatment), while the remaining systems were divided into separate treatments using two mangrove species (Laguncularia racemosa and Rhizophora mangle). Each system consisted of two water tanks linked by two hoses. The first tank contained 150 poeciliid fishes, while the second contained a biological filter of gravel and sand on the bottom, as well as a hydroponic arrangement of 34 seedlings. Water exchange between both tanks was performed over a 24-h period, every ten days for seven months, and the concentration of nutrients (NH4+, NO2–, NO3–, and PO4–3) was measured every 8 h. Laguncularia racemosa showed a higher growth rate compared to R. mangle, but there were no differences regarding the growth of fishes among the six systems. Final dissolved inorganic nitrogen removal was 42% in the control treatment and 90% in both treatments using mangroves. Dissolved inorganic phosphorus removal was 45% in the control treatment, 44% in the L. racemosa treatment, and 35% in the R. mangle treatment. Our results indicate that both mangrove species are capable of removing a considerable amount of nitrogen, but phosphorus removal was unsatisfactory. Seis sistemas de cultivo fueron construidos para evaluar el uso potencial de plántulas de mangle en la remoción de nutrientes. Dos de los sistemas no contenían plántulas (i.e., control), mientras que los sistemas restantes fueron divididos en tratamientos por separado con dos especies de mangle (Laguncularia racemosa y Rhizophora mangle). Cada sistema consistió en dos tanques de almacenamiento unidos por dos tubos. El primer tanque contenía 150 peces poecílidos, mientras que el segundo tanque contenía 34 plántulas en forma hidropónica y un filtro biológico de grava y arena en el fondo. Se hicieron recirculaciones de agua entre ambos tanques cada diez días por un periodo de siete meses. Durante cada recirculación, se midió la concentración de nutrientes (NH4+, NO2–, NO3– y PO4–3) cada 8 h. Laguncularia racemosa presentó una tasa de crecimiento mayor comparada con R. mangle; sin embargo, el crecimiento de los peces fue igual entre los seis sistemas. El porcentaje final de nitrógeno inorgánico disuelto fue 42% en el tratamiento de control y 90% en los tratamientos con L. racemosa y R. mangle. El porcentaje de remoción de fósforo inorgánico disuelto fue 45% en el control, 44% en el tratamiento con L. racemosa y 35% en el tratamiento con R. mangle. Los resultados indican que ambas especies de mangle son capaces de remover una cantidad considerable de nitrógeno, pero la remoción de fósforo fue insatisfactoria. 2015-12-18 2021-06-03T03:55:26Z 2021-06-03T03:55:26Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2521 10.7773/cm.v41i4.2521 https://hdl.handle.net/20.500.12930/7488 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2521/1570 Copyright (c) 2015 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 41 No. 4 (2015); 255-268 Ciencias Marinas; Vol. 41 Núm. 4 (2015); 255-268 2395-9053 0185-3880
