Nyong Autonomous Aquaculture
Akonolinga–Olama river sections · Score 67/100 · 115 floating cages in synergy with CODAM Mfou.
Location and characteristics
The Nyong River, the project's second aquaculture pole
The Nyong River is a major waterway crossing Cameroon's Centre and East regions. PROAQUI specifically targets the Akonolinga–Olama river sections for floating-cage deployment. The 67/100 aquaculture suitability score qualifies this site as conditional complementary: its development takes place in Phase 2 of the project, contingent on meeting explicit technical pre-conditions.

Strategic synergy
The operational partnership with CODAM
Zeideal Group develops the Nyong site in synergy with the Proaqui Nyong project, launched in June 2025 by Zeideal SAS and CODAM. Based in Mfou with a target capacity of 12,000 tonnes per year, this project shares the satellite hatchery with PROAQUI's Nyong site. This co-location in Mfou secures the fingerling supply, optimizes regional logistics, and anchors PROAQUI within Cameroon's existing aquaculture fabric.
Pre-conditions for development
Fully assumed transparency
The Nyong site is qualified as conditional complementary. Two technical pre-conditions are identified and their resolution is integrated into the implementation schedule:
- Macrophyte cutting on cage deployment target zones, to optimize oxygenation and limit health risks linked to dense aquatic vegetation.
- Reinforced anchoring systems sized to withstand floods, in line with the documented maximum flow of 1,226 m³/s. Technical specifications aligned with international fluvial operators' standards.
These actions precede any installation and constitute enforceable Phase 2 milestones.
Documented decision
The Djérem exclusion outside the Mbakaou reservoir
The natural course of the Djérem (outside the Mbakaou reservoir) was subject to a separate scientific evaluation and definitively excluded from the PROAQUI perimeter (score 22/100). This exclusion rests on three findings: insufficient depth (less than 3 meters), torrential regime incompatible with fixed-cage farming, extreme seasonal variability. This decision is scientifically documented in the v2 expert analysis and will not be subject to subsequent reassessment.
