I've just finished collating information for a report on UK MSC fisheries (wetfish only) for a customer and it makes interesting reading. They are determine to use only line caught British MSC accredited fish and will hear no different to this master plan of thiers.
Unfortunately the one snag to this plan is there are a total of only 15 accredited fisheries
1 Dover Sole
One of the mackerel fisheries has an element of their fleet as hand liners (less than 40%) other than that the other 14.5 fisheries are trawled.
Should make for an interesting meeting, wish me luck.
