Why Has Duckweed Not Taken Off as Low-Cost Animal Feed in Nigeria?

I grow duckweed for animal feed and also cultivate a separate batch in a clean-water trough for my own meals. It grows rapidly in warm conditions and can be harvested repeatedly once established. Its protein content can range from about 20% to 40%, depending on the species and growing conditions. That puts it in a similar range to some conventional feed ingredients used by poultry, fish and pig farmers. It could potentially reduce reliance on costly soybean meal when used properly in feed formulations. Nigeria has plenty of sunlight, warm weather and fish-pond runoff that could support production. Yet duckweed is still not widely grown commercially. Is the problem lack of awareness, poor market access, safety concerns, consumer perception, or weak data on feed conversion and return on investment? Has anyone raised duckweed at commercial scale or used it to replace part of poultry, fish or pig feed? I would like to hear practical results, including the challenges and any cost savings.
