Commercial catfish systems are frequently referred to as systems to be emulated in the public process of developing mariculture plans and legislation for the United States. The economic evolution of catfish culture is reviewed to identify the role of the public sector and market forces. An examination of catfish production operations of approximately 65 ha reveals near zero growth in returns on investment over the past 7 years. Following some technological improvements in the latter part of the last decade, the economic impact of technological change is not evident. High level managerial skill applied to the ponds and business are of paramount importance. A conclusion is that publicly supported pilot‐scale demonstrations should find justification in the testing and development of managerial skills as well as technologies. Thus, a training role for pilot‐scale facilities is worthy of public sector consideration.
