WATER QUALITY IN FISH MANAGEMENT

Water supplies for catfish ponds are usually of good initial quality. However, once the water is used for culture, its quality deteriorates. This deterioration of environmental conditions is ultimately traceable to the use of feed. Despite the use of high quality feeds and careful feeding practices, relatively little of the nutrient value of feed is converted to catfish flesh. The remaining nutrients derived from fish wastes stimulate excessive phytoplankton growth. High rates of phytoplankton metabolism cause pronounced diurnal fluctuations in dissolved oxygen concentrations, dissolved carbon dioxide concentrations, and pH. Such fluctuations cause stress in fish resulting in reduced fish growth rates, poor feed conversion, and reduced resistance to disease. In extreme instances, such as depletion of dissolved oxygen, fish may be unable to adapt and will die.

Rabbits Nutrition

Rabbits are small herbivores with specialized feeding needs and digestive systems.
