Reading this is infuriating. Seemingly fish farming is misunderstood and the high deaths are because of climate change (Icve heard this from colleague whose husband is in the fish farming industry) which means that jellyfish and algal blooms increase mortality.
Which sounds increasingly like fish farming in Scotland is decrasing in viability. So we maybe shouldn't be going so hard at farming fish? Like reduce the densities of fish and farms...
Can a Norwegian seafood giant allay locals' fears over a Highland fish farm?
