An example of the type of research conducted by the Aquatic Feeds and Nutrition Department on micronutrients is its work on the role of phytonutrients from shrimp pond microbial floc in the growth and health of shrimp and fish. Phytonutrients are plant compounds thought to have health-protecting properties. Our current research includes the following compounds: phytopigments-carotenoids, which are responsible for the pink color in cooked shrimp; phytosterols, which play an important role in steroid hormone synthesis and the molting process; amino sugars (e.g. glucosamine), which provide the building blocks for shrimp shell formation; phospholipids, which are important components of biological membranes; and bromophenols, which are responsible for the characteristic “seafood” flavor in fish and shrimp. Many of thesemicronutrients cannot be internally synthesized by the animal, and must therefore be consumed by the shrimp, either as part of the feed or as part of the floc that they consume.
Any micronutrient deficiency in aquatic feeds, whether from poor ingredient quality, suboptimal diet formulation, or deterioration due to feed processing and storage conditions, can compromise the animal’s health, resulting in disease or slow growth. This is one of the primary reasons why lab-based nutritional research to identify and quantify micronutrients is so important in optimizing the growth and health of aquacultured shrimp and fish.
