Aquaculture pole · Centre / East
Akonolinga–Olama river sections · 287 AKVA Group floating cages at full capacity · Mfou hatchery owned 100% by the project company (CODAM as operating partner).
Location and characteristics
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. Its development is contingent on meeting explicit technical pre-conditions (macrophyte clearing and flood-proof anchoring).
| Regions | Centre and East, Republic of Cameroon |
| Target sections | Akonolinga–Olama |
| Average pH | 5.8 (PMC 2025 measurement) |
| Average temperature | 24.8°C |
| Dissolved oxygen | 3.19 to 4.89 mg/L (macrophyte zones — SCIRP 2021) |
| Documented maximum flow | 1,226 m³/s |
| Aquaculture suitability | Validated, subject to technical pre-conditions |
Strategic synergy
Zeideal Group develops the Nyong-Mfou pole around its operational partnership with CODAM (Mfou District Development Committee), launched in June 2025. The Mfou hatchery, owned 100% by the project company (≈ 49 million fingerlings per year, CODAM as operating partner), serves PROAQUI's Nyong-Mfou pole. This co-location in Mfou secures the fingerling supply, optimizes regional logistics, and anchors PROAQUI within Cameroon's existing aquaculture fabric.
The site's three activities
Activity 01 — Farming
AKVA Group cages adapted to river conditions: Ø 18 m × 4 m, anti-flood anchoring sized for the peak flow (1,226 m³/s). Deployment under the 70/30 model (201 direct cages + 86 satellites). Consolidated production of 15,800 tonnes per year at full capacity (Phase 4).
Activity 02 — Reproduction
Capacity of about 49 million fingerlings per year, GIFT strain. Full consistency with the Mbakaou hatchery (same protocols, same strain). Operational partnership with CODAM in Mfou (no ownership or management).
Activity 03 — Downstream
IQF freezing of whole fish and on-site negative-temperature storage (no processing), to the same quality standards as Mbakaou. Outlets in southern CEMAC (Gabon, Equatorial Guinea) and the Cameroonian urban market (Yaoundé, proximity).
Pre-conditions for development
The Nyong site requires two structuring technical pre-conditions, identified and their resolution is integrated into the implementation schedule:
These actions precede any installation and constitute enforceable Phase 2 milestones.

Documented decision
The natural course of the Djérem (outside the Mbakaou reservoir) was subject to a separate scientific evaluation and definitively excluded from the PROAQUI perimeter 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 expert analysis and will not be subject to subsequent reassessment.
