The latest Marine Conservation Society (MCS) Good Fish Guide ratings changes show a "disappointing" lack of movement for UK fisheries both onto the 'Best Choice' list, and off the 'Fish to Avoid' list.

In addition, the charity said with Brexit, in whatever form, just around the corner, without strong post-Brexit fisheries management more fisheries could find themselves being red-rated and moved onto the Fish to Avoid list.

More than 100 ratings for 45 different species of fish that are caught within the UK’s exclusive economic zone are red-rated in the Good Fish Guide.
