摘要: Abstract Inbreeding could lead to a decrease in genetic variation within population and subsequent depression of performance traits. The purpose this study was investigate the effects inbreeding on growth-related traits, immune responses, antioxidant status acute hepatopancreatic necrosis disease (AHPND) resistant capacity ridgetail white prawn (Exopalaemon carinicauda) using new inbred line named EC5. results demonstrated that polymorphisms EST-SSR markers decreased with an increase artificial inbreeding, there less growth traits lower survival rate among populations than control population. responses were studied experimental full-sibling E. carinicauda at five levels coefficient (F = 0.785, F = 0.816, F = 0.859, F = 0.886, F = 0.908) under controlled laboratory conditions. affected total haemocyte count, antibacterial activity phenoloxidase (PO) activity, haemocyanin (HEM) concentration after ninth generation. Antioxidant showed similar pattern: superoxide dismutase (SOD) catalase (CAT) cell-free haemolymph decreased. infection Vibrio parahaemolyticus significant, as cumulative mortality shrimp (CP) significantly F9 generation EC5 family during 24–72 h V.
