Gut Structure

Optimal gut function and its efficiency is one of the keys to the successful commercial production of aquaculture species. The major function of the gastrointestinal tract is to process the ingested feed material and to digest and degrade this into a form that can be easily absorbed and assimilated by the animal. This process supplies dietary nutrients to the body tissues. Digestion by its very nature is a complex process involving enzyme and fluid secretions, motility, absorption and ultimately evacuation.

A healthy digestive system is crucial for optimal animal performance. The large surface area of the GI tract is necessary for the optimization of nutrient absorption and to allow the efficient passive transfer of nutrients to the blood. However the gut is protected by only one layer of epithelial cells and damage to these structures can therefore impact nutrient uptake and affect growth and performance.
