Stocking density is one of the most critical management decisions in aquaculture. While maximizing pond or tank capacity may seem economically efficient, high stocking densities and overcrowding are among the…
Bacterial infections caused by species of the genus Pseudomonas (such as Pseudomonas fluorescens and Pseudomonas aeruginosa) represent significant biological and economic challenges in aquaculture. Like many opportunistic aquatic pathogens, Pseudomonas…
Bacterial infections caused by the genus Edwardsiella represent significant biological threats to catfish aquaculture. Specifically, Enteric Septicemia of Catfish (ESC)—caused by Edwardsiella ictaluri—and Edwardsiellosis (caused by Edwardsiella tarda) are major…
Columnaris Disease—often referred to as “cotton wool disease” or “saddleback”—is one of the most common and contagious freshwater fish diseases worldwide. Caused by the bacterium Flavobacterium columnare, it poses a…
Red Spot Disease—clinically known as Motile Aeromonas Septicemia (MAS)—is a severe, systemic bacterial infection that poses a major threat to catfish aquaculture. It is driven primarily by bacteria of the…
Motile Aeromonas Septicemia (MAS) is a severe, systemic bacterial infection caused by Aeromonas hydrophila and related species. It poses a major risk to catfish aquaculture, functioning as both an acute…
Mistake 1: Inadequate Housing and Ventilation The problem: Many poultry operations in West and Central Africa use poorly ventilated structures—corrugated metal sheds without adequate openings, overcrowded pens, or housing that…
The value of a catfish harvest is not locked in at the moment the fish reaches target weight — it is preserved or eroded by every handling decision between harvest…
More catfish farming enterprises fail due to inadequate financial planning than to inadequate technical knowledge. The technical information required to raise African catfish commercially is widely available — the biology,…
The catfish farm that produces 75 tonnes per year but has no pre-arranged buyers for its harvest is not a profitable business — it is an expensive problem. Fish harvested…
