Abstract
The removal of ammonium (NH4+), nitrite (NO2â), nitrate (NO3â), and phosphate (PO4â3) in a closed silvofishery system was examined using three mangrove species (i.e., Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle). Specifically, six closed tanks were installed for this experiment with a population of 60 Dormitator latifrons fishes per tank. We planted 40 seedlings in each of three experimental tanks separated by species, while the remaining tanks were used as control. During 15Â weeks, nutrient concentrations among the three mangrove systems presented no significant differences (PÂ >Â 0.05). However, nutrient removal variability was minimum during the last 2-5Â weeks. Mangroves presented an average efficiency of 63% for the removal of NH4+ and NO2â. Contrary, the average removal potential of NO3â and PO4â3 was 50%. Results from this study suggest that the three mangrove species could be used in a closed silvofishery systems for the biological removal of NH4+, NO2â, NO3â, and PO4â3.
