Every second an average of 5,000 cubic metres (equivalent to two Olympic swimming pools) is exchanged with the deeper waters of Cook Strait at the entrance of Pelorus Sound.
With the current number of consented fish and mussel farms, the model suggests there is unlikely to be a marked change in nutrient levels in the ecosystem.
Since these reports were produced, the Ministry for Primary Industries commissioned further modelling in 2016 and 2017 to better understand the effects of proposed salmon relocations.
Council will continue to monitor water quality to track key indicators such as nutrient loading, which will also help verify the predictions of the models.
