There has been a planning application from MOWI β Reference number - 25/00093/MFF.
You can find the detailed documents here
The planning application impacts Etive 3 and proposes to replace existing 10 x 70m circumference pens in 2 x 5 grid with 6 x 120m circumference pens in 1 x 6 grid, including increasing biomass from 458.4 tonnes to 700 tonnes and installation of feed barge. See map below (the blue indicates existing Etive 2 & 3 and red is the proposed).
You can only object to this planning application for any or all the following reasons:
There will be use of surface and underwater lights as stated on page 3 of the planning application form (extract below):
βIn addition to any surface lighting the NLB require there may be periods between November and May where low intensity, downward-facing LED underwater lights may be deployed, at a depth of up to 10m. These are used to prevent early maturation when farming Atlantic salmon. Given the brackish water of Loch Etive, operational depth and orientation of the lights they are not anticipated to result in surface glare.β
