Using a two-stage evaluation trial, this proposed study will evaluate astaxanthin yeast as an immunostimulant in Pacific white shrimp Penaeus vannamei. For that purpose, commercially available astaxanthin yeast produced from a specially selected strain of the Saccharomyces cerevisiae will be used. The growth performance of shrimp P. vannamei will be observed using a controlled environment, and the survival of shrimp will be monitored during various challenge tests together with the gene expression during the challenge test, such as Prophenoloxidase (ProPO) activity, Superoxide dismutase (SOD) and lysozyme activity. The results of this research will provide all stakeholders, farmers, and academicians with a better understanding at molecular and protein levels of how astaxanthin yeast evoke the immune response in Pacific white shrimp Penaeus vannamei
To evaluate the growth performance of the pacific white shrimp, Litopenaeus vannamei, fed with graded inclusion levels of high protein insect meal to replace partially and completely fish meal (FM) in Indonesia. The study could also be expanded to evaluate the immune response and resistance of Vannamei against the common bacterial pathogen, Vibrio parahaemolyticus
This project compares the growth of tilapia fish fed plant-based feed supplemented with proteases with plant-based protein source feeds without proteases.
