This "galvanized steel plate fishpond flowing water aquaculture" model has three major advantages. To make money in aquaculture in Africa, traditional earthen ponds and net cages have too many problems: reliance on weather, low yields, frequent fish diseases, and slow growth. Now there's a new model—building circular fishponds on land using galvanized steel plates, equipped with a circulating water system to raise tilapia. Its advantages are simple and direct, effectively overcoming the various "failures" of traditional aquaculture.
Advantage 1: Yields increased dozens of times, less space, faster profits.
Traditional earthen ponds might only yield a few hundred kilograms of tilapia per acre per year. Using these galvanized steel plate ponds, a pond with a diameter of 7 meters and an area of less than one-tenth of an acre can raise 3 to 5 tons of fish per batch. This is equivalent to doing the work of dozens of acres of ponds with only 1% of the land.
Moreover, the fish move in flowing water with sufficient dissolved oxygen, growing to market size in just 5 months, much faster than traditional methods. Capital can circulate more frequently throughout the year, naturally increasing the speed of profit.
Advantage Two: Significant Cost Savings (Feed)
Feed is the biggest expense in fish farming, accounting for over 60% of the total cost. Traditional aquaculture involves scattering feed into ponds, but much of the feed goes uneaten or sinks to the bottom, resulting in low feed conversion efficiency.
Flow-through aquaculture systems, combined with automatic feeders, ensure that the fish fully consume the feed, achieving a feed conversion rate of around 1.5 (1.5 catties of feed yields 1 catties of meat), significantly lower than traditional methods. Reduced feed costs lead to a substantial decrease in overall cost, naturally increasing profit margins.
Advantage Three: Higher Fish Quality, Higher Price
Tilapia raised in earthen ponds often have a muddy taste and don't fetch a high price. Fish raised in flow-through ponds, constantly exposed to running water, have firm flesh, no off-odors, and consistently high quality.
These "premium fish" are highly sought after in the market, and it's normal for them to command a wholesale price 1-2 higher per kilogram than ordinary fish. This translates to several thousand yuan more in profit per batch from a single pond. Differentiate directly from the source, moving away from low-price competition.
In summary, the core advantage of this model is that it transforms fish farming from "agriculture" into "factory assembly line production." It saves space, produces faster-growing fish, has higher feed utilization rates, and ultimately yields high-quality, high-priced products. For investors looking to scale up their operations and earn stable profits in the African aquaculture industry, this is undoubtedly the most reliable and efficient path currently available.
