Overview

An industrial aquaculture project carefully calibrated


Zeideal Farm SA installs and operates a floating cage aquaculture facility on the Nyong River, in a two-phase trajectory: start-up with 12 cages in July 2027, organic ramp-up to 22 cages in April 2032.

Strategic location

The Mbalmayo–Olama site


The operating site is located on the Mbalmayo–Olama stretch of the Nyong River, in Cameroon's Centre Region. This location offers a rare combination of geographic, hydrological and logistic advantages:

Favourable hydrology

  • Average annual flow: 158 m³/s
  • Depth 4–8 metres on selected stretches
  • pH 6.8–7.4 · dissolved oxygen 5.8 mg/L · temperature 24–28°C
  • Water quality compatible with high-performance tilapia farming

Market proximity

  • 50 to 80 km from Yaoundé depending on the stretch
  • Less than 2 hours by refrigerated truck
  • RN2 and RN9 highways paved year-round
  • Yaoundé market: 4.3 million inhabitants

Species and standards

GIFT tilapia, world reference strain


The selected species is Nile tilapia (Oreochromis niloticus) GIFT strain (Genetically Improved Farmed Tilapia), all-male monosex above 95%. This strain is recognised by the FAO as the world's highest-performing on key technical parameters: growth rate, feed conversion ratio, sanitary resilience, survival rate.

Industrial architecture

Eight modules of land infrastructure


On the river bank, less than 200 metres from the cages, eight functional modules support the operation. The whole represents an initial investment of FCFA 70M, sized from the start for the mature configuration of 22 cages to avoid overhaul costs.

01 · Office and coordination

60 m², satellite Internet connection, video conferencing, secure archives, video surveillance of cages.

02 · Team housing

120 m², capacity 10 people, sanitary blocks, common kitchen, rest area.

03 · Equipment and feed warehouse

200 m² ventilated, hygrometric control, capacity for 3 months of feed (~120 tonnes).

04 · Maintenance workshop

80 m², pneumatic and electrical tools, repair pit, critical parts stock.

05 · Embarkation quay

30 m aluminium floating pontoon, capable of supporting 5 t per operation, automatic weighing.

06 · High-pressure borehole

Depth 80–120 m, minimum flow 5 m³/h, raw filtered water.

07 · Security

1.2 km wire fence height 2.5 m, motorised gate, 24/7 security.

08 · Cold room

20 m² positive (+2°C) + 8 m² negative (-18°C), dedicated backup generator.

Integrated cold chain logistics

From cage to stall in less than 24 hours


The cold chain logistics is secured end-to-end, from harvesting on the cages to delivery to Yaoundé market customers. This structuring investment (FCFA 165M, i.e. 34% of initial CAPEX) constitutes a determining competitive advantage against frozen imports whose organoleptic quality is degraded by cold chain disruption.

Refrigerated truck

5 tonnes brand new (Toyota Dyna or Mitsubishi Canter), secure route, GPS tracking.

Cold rooms

Mbalmayo site (28 m²) + Yaoundé warehouse (42 m²), positive and negative.

Power continuity

Backup generators 25 kVA × 2, automatic switchover without chain disruption.
