Fall, 62, walks along the beach in this fishing village in the north of Senegal, his blue-grey boubou flapping in the dry, dusty wind, a bright red flowered umbrella shielding him from the scorching sun.
“This is the great shark cemetery,” he says waving his hand dramatically across the beach where dried hunks of shark meat are piled up, filling the air with a musty, acrid odour as suffocating as the heat.
Colourful painted pirogues line the beach where children play and sheep wander around. A giant pelican is curiously tethered to one of the crumbling houses.
Saint Louis is one of the biggest shark landing sites in Senegal and one of scores along the west African coast where the predator is quickly disappearing.
Fall’s sons have been gone for two weeks deep into Mauritanian waters for a voyage which, including food, water, fuel and salt to pack the fish, can cost more than 500,000 CFA (750 euros/$1,000).
Spurring these fishermen on is the insatiable Asian appetite for shark fins, which make their way onto ostentatious dinner tables in Hong Kong, Taiwan and Japan.
“The fins don’t stay here, they are worth a lot of money,” says Fall.
He explains that when a boat lands, amidst the chaos of bartering and buying shark meat to be dried, smoked and sold in the region, the fins are swept away by intermediaries to Dakar, and treated very carefully.
“The fins are gold, sometimes we keep them in our own living room – with the air conditioning on,” he laughs.
Often the intermediaries will meet with Asian businessmen in a Dakar hotel to hand over the booty.
“You bring the bags, go into the hotel, hand over the bag, they hand over the money.”
Mika Diop, a biologist and coordinator of the Sharks sub-regional Action Plan (SRPOA-Sharks) says that depending on the size and species of the fin involved, they sell for up to 100,000 CFA (150 euros) per kilogram (2.2 pounds).
