What’s in Our Northern Streams?

Blue Planet Aquarium introduces you to freshwater life that few of us have seen first-hand. These are inhabitants of the waters of the temperate zones of the northern hemisphere, including the rivers and streams of the British Isles.

The Industrial Revolution polluted many of Europe’s waterways and it has only been in the last 50 years that they have started to recover. However there are new threats; these include the introduction of invasive species such as the CHANNEL CATFISH and BROOK TROUT into many European waters.
