As said in one of my articles on this blog, overstocking is one of the most common reasons why catfish farmers fail. Overstocking could lead to unnecessary competition for food, oxygen, space, and other limited aquatic resources. Sometimes, overstocking could lead to rapid spread of infection. If infection is not well managed in an overstocked pond, high level of mortality will be recorded. Also, poor growth in catfish can also be caused by stocking more than pond capacity at a time.
