are all west coast scotland sea lochs trawled?

[thedogfisher]

Hi to one and all,
Have started sea fishing again after an absence of 10 years and I am surprised and dismayed at the number of small fish I am catching and lack of codling in the Gaerloch and loch long, spent 3 days on loch Lihne and again a few fish caught but none worth keeping.
Does anyone know any sea loch on the west coast that is fishing well just now and any bait and tackle tips would be greatly appreciated,
cheers
