Abstract

Diseases on shrimp postlarvae caused by bacterial and fungal still remain an important concern due to their economic values. Application of microalgae as natural feed has brought promising results for growth of shrimp postlarvae. The aim of this research is to apply fusant of Dunaliella and Chlorella microalgae and to detect feed effect on microbial diseases resistance on postlarvae. The research was conducted using bacterial and fungi from contaminated shrimp postlarvae. Microbial species were characterized based on morphological and biochemical tests. Total number of bacteria ranging from 21.7 u 105 cfu to 32 u 105 cfu while fungal calculation about 6 u 102 cfu. Microorganisms analysis presumably belong to genus Vibrio, Pseudomonas, Aeromonas, Alcaligenes, Bacillus, Staphylococcus, Hafnia and Fusarium. The absence of V. harveyi pathogen indicated that the fusant serve as the main source on increasing of resistance to diseases and thus reducing the mortality of shrimp postlarvae
