The production of Pacific white shrimp Penaeus vannamei is expected to continue to increase, mainly driven by the increase in global population and the increasing public need to consume healthy food. However, several challenges, such as market price fluctuations, decreasing prices at the farm level, and increasing feed prices but not accompanied by increased in feed quality, become the inhibiting factors for production efficiency, effectiveness, and profitability. Since feed accounts for 50 - 70% of production costs, farmers expect the feed used for production able to meet the specific nutritional requirements of shrimp to grow optimally with high yield and survival rates. In this webinar, the concept of ideal protein in feed will be discussed, how to distinguish between true protein and crude protein, and the specific needs for essential and non-essential amino acids, digestible energy, lipids, and other nutrients, such as vitamins and minerals, to optimize growth, metabolism, and physiological function of shrimp. Since shrimp are vulnerable to disease infection due to a lack of an adaptive immune system and only depend on the innate immune system, the development of functional feed will also become part of the discussion. Finally, high-quality feed without good feeding management practices will also affect the effectiveness and efficiency of production. For that, the advantage and disadvantage on the use of traditional methods, automatic feeders, and sound-based feeding systems as the feeding management system will be discussed in detail. Last but not least, the method of determining the amount of feed using feeding index and feeding ratio also become part of this course.

He has published more than 35 peer review research articles in the area of his expertise which include Aquaculture nutrition, shrimp and fish farming, functional feed, immunology, aquaculture technology and diseases management. In addition, his PhD’s Dissertation focus on ‘Evaluation of Advanced Soy Products in Diets Fed to Florida Pompano’ and master’s thesis on ‘A toolbox for Immune Parameters of Artemia’ provides beneficial information to the aquaculture industry. Dr. Romi was awarded two scholarships, the VLIR-UOS scholarship to pursue his Master of Science in Aquaculture at Ghent University – Belgium and the Fulbright scholarship to pursue his Ph. D in Fisheries and Allied Aquaculture at the Auburn University, Alabama, USA. Currently, Dr. Romi focus on the development of intensive shrimp farming system and economical aqua-feed, evaluation of nutritional requirements for shrimp and fish as well as facilitate the evaluation of novel ingredients and feed supplemental properties to enhance the growth and health status of aquatic organisms. Dr. Romi also act as a promoter to link the research institutes with industry to review the feed formulations and manufacturing process, aquaculture management practices, and identify relevant research to enhance the aquaculture productivity and efficiency.
