Red Lionfish the “terminator” of the Caribbean sea?

Recent research conducted in the Bahamas provides more evidence that, unlike other predators, lionfish have a unique invasive character of pursuing hunting even when levels of prey diminish and more energy is required. Since the 1980s the presence of lionfish increases mortality rates and threatens the extinction of entire local fish populations such as the fairy basslet.

While “there's a strong pressure here for natural selection to come into play eventually," says Ingleman of Oregan State University, "We know that fish can learn and change their behaviour, sometimes over just a few generations. But we don't have any studies yet to demonstrate this is taking place with native fish populations in the Atlantic." 

In 2010 the Regional Lionfish Committee with support of UNEP CEP and partners launched a guide to minimise the impact of the Lionfish in the Wider Caribbean Region. Take a look:

The Marine Debris Programme economic study of National Oceanic and Atmospheric Administration in the U.S. (NOAA) shows that marine debris has considerable economic costs to ocean, wildlife, residents of coastal communities and users of local beaches:

Residents of Orange County in California lose millions of dollars each year as visitors avoid dirty beaches and moreover increase environmental impacts by travelling longer distances.

Reducing marine debris even by 25% at beaches in and near Orange County could save residents roughly $32 million during three months in the summer.
