In Brief
- •The Marine Conservation Society downgraded European hake from green to amber due to declining stocks and increased fishing pressure.

Why It Matters
The Marine Conservation Society's Good Fish Guide helps consumers and businesses make sustainable seafood choices. The downgrades highlight the need for diversifying seafood choices and avoiding those most under threat. This is particularly important given that most seafood consumed in the UK comes from just a few species, putting significant pressure on wild stocks.
