“Rethinking Aquafeeds: Can Sub-Saharan Africa’s Aquaculture Thrive Without Wild Fish?”
As aquaculture expands across Sub-Saharan Africa, the overreliance on fish-based feed raises critical sustainability concerns. How can we break free from the "fish in, fish out" cycle without compromising growth and nutrition? Innovative alternatives—plant proteins, insect meal, and single-cell ingredients—offer a pathway to a more resilient industry. But are they viable, accessible, and nutritionally adequate? The future of fish farming depends on bold discussions and decisive action. Join the conversation on sustainable aquafeeds and help shape the next wave of aquaculture in Africa!
Would you like it to be more technical or tailored to a specific audience?
yes. by developing a more sustainable and self-reliant aquaculture industry that could contribute significantly to food security and economic development.
Hi Arnold,
Yes, you can make aquaculture thrive without wild fish. Please consider this ancient mariculture technology called clam gardening. By constructing rock walls on the low water tide level, sloping clam beaches were naturally transformed into flattened terraces, increasing considerably the yield of shellfish production.

Clams and other bivalves contain the same Long Chain Polyunsaturated Fatty Acids (LCPUFA) as forage fish, making them suitable for food and essential for aquafeed.
