Recently, burbot has been introduced as a new aquaculture species in Belgium for both flow-through and recirculating aquaculture systems (RAS). While this fish species can be successfully cultured in RAS, the impact of long-term exposure to high concentrations of NH4+ on burbot performance is unknown. The effects of toxic un-ionized ammonia (NH3) are well-studied for several aquaculture species, but there appears to be no literature on the chronic effects of elevated ionized NH4+ concentrations. For commercial farms, it is crucial to identify the maximum tolerable NH4+ concentration, in order to adequately dimension the biofilter capacity.
