Pepis, the bearded skipper of a small fishing boat, deftly picks up two lionfish caught in experimental traps off the coast of Cyprus, cuts off their venomous spines, guts them and tosses them into a bucket.
Around him, the Mediterranean looks like a pane of glass, its calm surface giving little hint of the dramatic transformation unfolding underwater.
Pepis’ practiced routine is part of a wider effort by scientists to track and control the spread of invasive species such as lionfish in these waters. Here life is changing, caused by a combination of warming sea temperatures and the Suez Canal which has eased access for fish from more tropical climes.
