Where Soybeans Meet The Sea: Midwest Aquaculture May Boost Demand For Local Grain

Midwestern fish farmers grow a variety of species, such as tilapia, salmon, barramundi and shrimp, all of which require a high-protein diet. The region grows copious amounts of soybeans, which have a lot of protein, but these two facts have yet to converge.
Take Eagle’s Catch, a tilapia farm in Ellsworth, Iowa, where a nearly 4-acre greenhouse is filled with tanks that segregate the fish by size. CEO Joe Sweeney said he feeds the fish a soybean-based diet he buys from a processor in the South.
