Intestinal absorption

• The fish intestine is the main site of absorption. The functional morphology and physiology of the intestinal epithelium have evolved to selectively absorb essential nutrients as well as water and ions from the ingested food and water, while preventing entrance of harmful substances. Membrane-bound transport and channel proteins together with endocytotic mechanisms ensure a well-controlled uptake. Being a multifunctional tissue, there is a constant balance between the different physiological tasks of the intestinal epithelium, and both internal and external factors can affect and control these events that are of fundamental importance for development, growth, and performance of the fish.
