  virulent and most dreadful viral outbreaks in shrimp culture. The potential antibacterial effects of Bacillus subtilis silver nanoparticles (AgNPs) from the gut of Litopenaeus vannamei were studied. The AgNPs has ~ 420 nm in UV-visible spectrum, diameter 5-25 nm with smooth spherical shape (characterized by transmission electron microscopy) and 2θ values corresponding to the presence of silver crystal (X-ray diffraction spectrum). The AgNPs showed promising activity against Vibrio parahaemolyticus (21.25 ± 2.55 mm) and V. harveyi (19.27 ± 1.36 mm) as compared with B. subtilis, silver nitrate (AgNO3) and control. Four different experiments were conducted using different feeding behavior of L. vannamei. In comparison to untreated control group, final weight (14.89 ± 0.03 g), weight gain (9.36 ± 0.01), specific growth rate (S.. View More»
