The McToob is the latest lionfish containment device to hit the market. It was invented by James McVey who lives here locally on Grand Cayman, where I live.

The rectangular box is 22 inches long and will hold 50% more volume than a 6.5 inch diameter, … Continue reading

So what is a polespear? It’s an underwater tool for catching (spearing) fish. If you look at the picture of me above you will see the one I use.  A polespear is basically made up of a pole, a spear tip and a rubber loop. The pole is usually between 2.5-feet and 10-feet long and made of fiberglass, carbon fibre, aluminium or graphite. The longer versions often break down into several pieces that screw together.

Lionfish fighting it out like Mike Tyson

OLYMPUS DIGITAL CAMERA

Since 2009 when lionfish came to Grand Cayman I have dived with them many times with or without my pole spear. Most of the time I see a single lionfish trying to hide itself somewhere on a mini-wall. Or I see one hanging around pointing its tail and therefore spines in my direction. Or I see a whole group together, my record for that is about 17 together in one small area. I am led … Continue reading

We will never be able to eradicate them completely but we can, and are, controlling their numbers. Grand Cayman is only 22 miles long by about 4 miles wide and most importantly it has a very small coastal shelf. This is a view of part … Continue reading
