In the schrimp-farming process at Vietnam has used antibiotic mostly, this leads status of antibiotic resistant bacteria and product do not qualified to the market. Bacteria, especially actinobacteria, had resistantant ability to human pathogenic bacteria in water and they have an important role in sustainable aquaculture. This study aimed to isolate and select good actinobacterial strains against human pathogenic bacteria, from 8 samples of schrimp-pond water at 3 sites Ngu Lac,
Phuoc Tri and Long Toan of Duyen Hai district, Tra Vinh province on Gause-1 agar medium. Fiftythree actinobacterial isolates were isolated and 12 isolates were identifed as resistant to Bacillus cereus and 8 isolates were identifed as resistant to Escherichia coli by well-diffusion method. There were 7 isolates had good resistance to select for PCR technique and sequencing and the result were determined 7 these strains: NL1-1.9, NL1-18a, NL2-2,1b1, NL2-2.2, PT1-1.7a, PT2-2.8a,
LT1-1.1 belonged to three genere: Streptomyces, Nocardioides, Glutamicibacter.
