Scientists have seen an amazing boom in sealife around a small island after fishing was completely banned there three years ago
It's not just common fish that are doing well off the island of Lundy on the Devon coast - but all types of creatures, like this sea anemone
There are six times as many lobsters in the no-catch area as there are outside it!
Because there's no danger of damage by fishing nets and anchors, the whole sea bed has recovered
There are even things like coral growing!
We could soon be seeing lots of fishing-free zones popping up around our coast, as scientists reckon they might help protect endangered species
