From a control room in the middle of Dubai's desert, Norway's sunrises and sunsets and the cool currents of the Atlantic are recreated for the benefit of thousands of salmon raised in tanks despite searing conditions outside.

Dubai is no stranger to ambitious projects, with a no-limits approach that has seen a palm-shaped island built off its coast, and a full-scale ski slope created inside a shopping mall.

Farming - Salmon - Desert - Something - One

But the farming of salmon in the desert is "something that no one could have imagined", said Bader bin Mubarak, chief executive of Fish Farm. "This is exactly what we're doing in Dubai."

Inside the facility, waters flow and temperatures fluctuate to create the most desirable conditions for the salmon living in four vast tanks.

Sunrise - Sunset - River - Current—and - Waters

"We provide for them a sunrise, sunset, tide, a strong current or a simple river current—and we have deep waters and shallow waters," Mubarak told AFP.

Even for a country known for its extravagant ventures, building Fish Farm, located along the southern border of the emirate, was a challenging endeavour.

Salmon - Waters - Iceland - Norway - Scotland

Salmon usually live in cold waters such as those in and off Iceland, Norway, Scotland and Alaska—which is why the farming of Atlantic salmon in a country where temperatures can reach up to 45C (113 degrees F) is a stretch to say the least.

"Creating the (right) environment for the salmon was the hardest thing we faced," Mubarak told AFP.

Idea - Water - Water - Ocean - Salinity

"But we came up with the idea of dark water that resembles deep water, a strong current like the ocean with the same salinity and temperature of the Atlantic."

'Greatest production'

Farm - Fingerlings—or - Juvenile - Hatchery - Scotland

Fish Farm bought some 40,000 fingerlings—or juvenile fish—from a hatchery in Scotland and thousands more eggs from Iceland to raise in open tanks in Dubai's southern district of Jebel Ali.

Salmon are born in freshwater but live in salt water for much of their lives before returning...
