Envisat radar surveillance protects endangered prehistoric fish   A French navy patrol ship approaches a fishing ship from Honduras after firing warning shot off the coast of Ile de la Reunion 01 July 2004. The boat is suspected of illegal fishing.   This is the endangered Patagonian Toothfish Dissostichus eleginoides. Conservation and management of the species is led by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) but according to TRAFFIC, the wildlife trade monitoring programme, its survival is under threat due to unregulated and illegal fishing across the Southern Ocean.

Also known as Grande Terre - and originally called Desolation Island - Kergulen Island has a cold, windswept climate and features Cook Glacier on its western side. Kerguelen is surrounded by rich fishing grounds.   ESA's ten-instrument Envisat environmental satellite has been observing the Earth for more than three years. Picture by EADS Astrium.
