Quoting from the blog posting by Lee Drever on Tue, May 01, 2012:
"Bell Aquaculture, the United States' largest yellow perch (perca flavescens) farm, has added soil fertilizer to its product line. Advocates for aquaponics have always known that the effluent from recirculating aquaculture systems makes great plant food. Bell are now offering this nutrient-rich fertilizer to its customers"
