Abstract
The present study aimed to evaluate the mortality, reactive oxygen species production (ROS) and total hemocyte counts (THC) of the marine shrimp Litopenaeus vannamei infected with the white spot syndrome virus (WSSV) at three levels of oxygen saturation. For this, 360 shrimp (20±2g) were distributed in 24 tanks (60L), divided in two groups (infected and non-infected), which were subjected to 30, 60 and 100% of dissolved oxygen saturation (in quadruplicate). During 96 hours after infection, daily hemolymph samples were collected for hemato-immunological parameter evaluation (THC and ROS) and dead animals were removed and computed to assess cumulative mortality rates. In the infected group, animals subjected to 100% saturation showed higher ROS production (P
