Daily feeding to apparent satiation is the most common feeding strategy followed in U.S. catfish industry as it maximizes growth and fish yield. However, under conditions of tighter credit or higher feed prices certain farmers have to feed catfish less frequently than daily in order to adjust to available capital. In this study we detail the production and economic effect of various feeding frequencies employed in research ponds from three different decades (Li et al. 2006; Nanninga and Engle 2010; Kumar et al. 2021) under varying management conditions. The feeding frequencies analyzed included every day, every other day, and every third day feeding to satiation. Economic benefit associated with every other day and every third day were analyzed using a partial budget equilibrium evaluation. All three studies reported every other day feeding to have better feed conversion ratio (FCR) and subsequent 32% reduction in feed costs relative to every other day feeding. However, this was at a cost of 18% reduction in fish yield. Under current conditions, every day feeding is more economically beneficial than every other day feeding as the total reduction in feeding cost does not offset the revenues lost from reduced fish yield. However, the study found that this recommendation is sensitive to catfish prices and feed prices (Table 1). Hence careful consideration of market conditions needs to be incorporated into farm management decisions while selecting and implementing reduced feeding frequency on catfish operations. Under current economic conditions (feed price =$605/MT and fish price =$2.85/kg), if available capital is sufficient feed, it is economically beneficial to feed every day to satiation to take advantage of fish growth and gross returns.
