Abstract
In the development of shrimp Litopenaeus vannamei farming, the main problem is disease susceptibility. To control diseases, preventive actions are one of the most important strategies. The general objective of this study was to obtain bioactive compounds of microalgae Tetraselmis chuii and Dunaliella salina that have the potential to increase growth and resistance to disease in shrimp. The methods used in this research were: extraction of microalgae, supplementation of microalgae extract into shrimp feed, and microalgae application test as feed supplement for shrimp as an enhancer of growth. The results showed that feed containing two microalgae extracts showed a higher crude protein content than the control. Shrimp fed for 28 days with feed containing T. chuii extract (2.193%. day-1 ) showed a higher Specific Growth Rate than those administered feed with D. salina extract (1.437 %. day-1 ). © 2021, BIOFLUX SRL.
