EPA Director releases latest finfish biomass Determinations for Macquarie Harbour

The Director of the Environment Protection Authority (EPA), Mr Wes Ford today released his latest Determinations, lowering the maximum permissible biomass to 14,000 tonnes of finfish per hectare in Macquarie Harbour for the period from 14 February to 30 April 2017.

Mr Ford said he based the new Determinations on a range of information, including a review of the most recent research findings provided by the Institute of Marine and Antarctic Studies (IMAS).

He considered the very low levels of dissolved oxygen (DO) in the deeper waters of Macquarie Harbour, the extent of the presence of Beggiatoa species in the harbour currently, and its increase over the past six months, as well as a decline in benthic fauna in the vicinity of the marine farms.

The Director’s announcement today follows his advice to the three Macquarie Harbour salmon aquaculture companies and the State Government on Monday 16 January regarding the changes and his intention to release a copy of the latest Determinations​.
