Abstract: After three generations of selective breeding for whitespot virus resistance, 29 families of Penaeus vannamei were divided into three groups: high, moderate and low resistance. After infection with whitespot, the average survivals for the groups were 22.7, 9.08 and 0.78 percent, respectively. The peak in mortality in the high-resistance group occurred two to three days after the peaks in the low-resistance group and controls.
