Fish drying systems in Senegal
What the crop demands, what the country imposes, and what that means for capacity.
Senegal’s artisanal fishery is among the largest in West Africa, landing at Joal, Mbour, Kayar and Saint-Louis, and a substantial share of it is processed by women into dried, fermented and salted products that move across the whole region. The processing sites are open ground beside the beach, and product quality varies with the weather and with the flies.
The situation in Senegal
The closest West African coast to Europe, with Dakar four days’ sailing from Algeciras and a direct air-freight route that other producers in the region do not have. Its agricultural calendar is also the odd one out: the rains arrive late and the mango season runs through the northern summer, when Sahelian supply has finished. That timing is worth more than any processing efficiency.

What fish drying demands
Fish is the most time-critical and highest-risk product here. Spoilage begins at landing, food-safety stakes are real, and the fat content of the catch decides the temperature ceiling — oily species cap at 45 °C or they finish correctly dried and rancid. What controlled drying replaces is smoke racks and open ground, both of which cost quality and, in the case of smoke, health.
Harvest calendar
Year-round, with peaks November to May when the cold-water upwelling brings the pelagic shoals inshore. Sardinella and bonga dominate the volume, and both are oily.

Fuel available in Senegal
The groundnut basin supplies a large volume of very light groundnut shell: briquetting is not optional but a precondition. Rice husk in the river valley.

Market and buyer requirements
Regional — Burkina, Mali, Côte d’Ivoire and beyond — as dried and fermented fish, plus a European market for higher-value species that depends entirely on documented hygiene.

Frequently asked questions
Why are Senegalese pelagics difficult to dry?
Because sardinella and bonga are oily, and oily fish must cap at 45 °C. Above that they finish correctly dried and go rancid within weeks — oxidation, not moisture, is what limits their shelf life, and the failure appears after the product has shipped.
What does an enclosed chamber change at a landing site?
It removes the weather, the flies and the dust from the process. A batch on open ground beside the beach is exposed to all three; the same fish at 40–45 °C to a water activity of 0.70 or below is a documented product rather than a variable one.
Is 8 t/day realistic for a processing group?
It is a substantial landing-site operation, producing around 2.7 tonnes of dried fish a day at roughly 3 : 1 over a 10 to 16 hour cycle. At that scale a women’s processing group can supply regional wholesalers directly rather than selling into the beach trade at whatever it pays.
