Scotland produces 80% of the UK’s seed potatoes. It’s an excellent industry with many years of expertise producing a quality product where 13.5% of its sales are to the EU.... (Brexit) means that seed potatoes from Scotland will lose their EU market – they will not be allowed to sell their products in the EU as they did before. They will have to rely on sales within the UK to make up this loss.  BUT to make matters worse  EU countries will be able to export their seed potatoes without hindrance onto the UK market.

Management of fisheries will ‘normally’ be with the devolved administrations which means that can also be controlled by the UK Government in London. The whole shebang will cost unknown amounts of money to set up and administer. And we still have to sell the fish."
