Starting to make sense now, here is a quote from an EPA document;

"I have determined that within the total area covered by marine farming leases 266, 219 & 214 the maximum permissible biomass of marine farmed salmonids that may be stocked by the Tassal Group over the period 14 February 2017 – 30 April 2017 is 25.35 tonnes per hectare. This is a reduction from the Secretary’s determination of 28 April 2016 of 33.58 tonnes per hectare and reflects a short-term harvest strategy which will be reviewed at the end of the designated period."
