He's a fisherman in Buerela - on Spain's northern coast.
He arrived here 17 years ago on a different boat - one departing from his home country of Senegal in search of a better future.
As more and more Senegalese migrants seek out the sea to reach the Canary Islands, Diouf is reminded of his own journey.
"Seeing the boats arriving to Spanish territory is very hard. Crossing the Mediterranean without knowing what you will face (is hard). You are facing death."
Diouf was part of a 2006 migration surge from West Africa through the Canaries, located around 60 miles off Africa's northwestern coast.
More than 30,000 migrants arrived that year.
That record number was broken last year...
...and nearly 7,000 people died in 2023 while attempting the crossing, according to rights group Caminando Fronteras.
Diouf left Senegal as it saw a dramatic plunge in coastal fishing stocks - partly due to industrial fishing by European Union states, according to academics and NGOs.
Today - earning a living from fishing there has become even more challenging.
Ocean conservation NGO Oceana said some 57% of the stocks in Senegalese waters are estimated to have collapsed.
Diouf blames his country for selling the best fishing zones to international operators.
"If African governments had done what they were supposed to do, there would be no people trying to cross, or even no need for visas to come and work in Europe. Is there work in Africa? Yes, but how can we work in Africa if they don't let us work?"
It took him a decade - but Diouf was able to make his way north to Burela...
...where immigration is largely welcomed by the locals.
Francisco Gonzalez, the captain of the boat Diouf works on, says Spain's fishing industry can't survive without migrants.
"There are very few young Spaniards in the fishing industry. So, the future lies in training migrants who come from abroad and want to work here."
But even in Burela - Diouf's future isn't safe...
as experts warn Spain's fishing industry may not survive, despite workers like Diouf.
About half of the fleet practices longline hake fishing in Burela...
...a practice that the EU has now included in its restrictions on bottom trawling.
The industry there could collapse within three years.
Diouf is preparing for the day when he can no longer fish.
