The Invasion of the Lionfish – 2016 update

The first report of a lionfish in the northern Gulf of Mexico was in 2010. It was a small individual that struck more curiosity than anything else.  By the end of the following week another was seen and now, here off the coast of Pensacola, are some of the highest densities found anywhere in the …
