Alleviating effects of Gracilaria verrucosa supplement on non-specific immunity, antioxidant capacity and immune-related genes of pacific white shrimp (Litopenaeus vannamei) provoked with white spot syndrome virus.

ABSTRACT: Our work evaluated the possible underlying roles of dietary dried seaweed (Gracilaria verrucosa; GV) on the inherent immune response, antioxidant capacity, immune-related gene expression, and protection of whiteleg shrimp (Litopenaeus vannamei) contra white spot syndrome virus (WSSV). Three hundred and sixty healthy L. vannamei (15.26 g ± 1.29 g) were graded into four supplemental groups ( Triplicate/group) and fed with diets including 0 (control), 2, 4, and 8 g GV (kg diet) ^-1 for 21 days. Following the feeding period, each group of shrimp received an intramuscular WSSV injection (1.4 × 10⁶ copies/ml). Hemolymph and gills samples were collected before and after the challenge with WSSV. Notably, the administration of dietary GV significantly enhanced the innate immune
