Over the five year period from 2011 to 2015:
Less than half of the fish and shellfish landed from the UK Exclusive Economic Zone (EEZ) by EU fishing boats (43% by weight) was caught by UK boats
If landings by non-EU (Faroese and Norwegian) fishing boats are included, UK boats’ share of the total landings from the UK EEZ falls to less than one-third of the total (32% by weight)
Non-UK European Union fishing boats landed about 700,000 tonnes of fish and shellfish, worth almost £530 million, from the UK EEZ each year on average
UK fishing boats landed 92,000 tonnes of fish and shellfish, worth about £110 million, from other areas of the EU EEZ each year on average
Non-UK EU fishing boats therefore landed almost eight times more fish and shellfish (by weight) from the UK EEZ than UK boats did from other areas of the EU EEZ, or almost five times more by value
Whilst in the EU, UK (and so, Scottish) sea fisheries are governed by the Common Fisheries Policy (CFP).
