There has been an increasing interest in enhancing freshwater aquaculture processes without hindering the progress of the Water Framework Directive. This constitutes the first study to describe a new concept in integrated multitrophic aquaculture (IMTA) that uses cutaway peatlands (bogs) to farm rainbow trout and Eurasian perch with associated organic status that is powered by wind energy and utilizes algae and duckweed to treat rearing water. Approximately 5% of Ireland comprises bogs that support natural ecosystems where there is a pressing need to develop alLemalive innovation to that of burning peal in order to reduce Ireland's carbon emissions. Specifically, this study evaluates water quality from this new IMTA where intake and terminal holding tank samples were evaluated from May to August 2019. Physicochemical parameters (temperature, pH, nitrogen, phosphorus, oxygen, suspended solids, hardness and alkalinity), and ecoloxicological bioassays (Pseudukirchneriella subcrapilutu and Daphnia pulex), were used to investigate the potential effects that introducing aquaculture processes may have on peaLlancls. Nitrite (P < 0.001), nitrate (P = 0.016), and chemical oxygen demand (P = 0.011), were the only physicochemical parameters that differed significantly between the intake and holding Lank water indicating that water quality for the most part remained unchanged. Low levels of toxicity were observed between the bioassays suggested the introduction of the processes into the bog were unlikely to cause adverse effects on the ecosystem and the organisms therein. Observations were similar to or lower than those reported previously by other researchers for intensive flow-through aquaculture processes that discharge to receiving water. Findings from this study support the use of-peatlands as future locations for integrated aquaculture processes. (C) 2019 Elsevier B.V. All rights reserved.
