Biochemical oxygen demanding (BOD) dispersion model validation standards
The Aquaculture Activity Regulations (AAR) under the Fisheries Act came into effect in July 2015. The AAR Monitoring Standard for finfish marine aquaculture requires that dispersal models be used to predict contours of the rate of bottom deposited biochemical oxygen demanding matter released from fish farms and that some form of an aquaculture waste deposition model be used to make these predictions. The model to be used is not specified. In an effort to help farm owners, operators and regulators become sufficiently aware of models that are potentially available along with an identification and evaluation of how they function, what they assume and what the accuracy of their predictions are, this project will
- review existing literature on aquaculture deposition models, and their applicability to AAR requirements and potential model audit criteria; and
- review resuspension model literature and refine some recent aquaculture motivated resuspension models.
Coming out of this analysis a template for evaluating dispersal model outputs will include: a summary of typical model inputs; parameters and typical values; reported sensitivities; and potential means of validating model implementation.
