The bay has gone over the tipping point and needs help to recover that is for sure, dumping large areas of shell for the mussels to attach to would be easy enough and not even that expensive in the grand scheme of things, banning bottom trawling over the vast areas required would meet some stiff opposition tho I bet.
Also fishing forestry farming and councils need to be held to account and should be paying to fix it, it is not one single sector at fault but all of them combined.
