In the Exuma Cays Land and Sea Park – the oldest, largest and ‘best-policed’ marine reserve in the Bahamas – researchers found 10 times fewer lionfish in parts of the reef where there are lots of groupers. Fishing has been banned in the park for 20 years, so it now boasts a healthy grouper population. On other reefs where fishing is rife lionfish populations are exploding. ‘Where you see plenty of grouper, you see fewer lionfish.’ Dr Alastair Harborne, University of Exeter said.
