Taurine Supplementation Enhances the Resistance of <i>Litopenaeus vannamei</i> Postlarvae to Low-Salinity Stress.

ABSTRACT: In aquaculture, Pacific white shrimp (Litopenaeus vannamei) growth in low-salinity waters is limited by osmoregulatory stress; therefore, improving resistance to low-salinity stress via nutritional modulation is key. In the present study, shrimp postlarvae were provided with a taurine supplement under low-salinity stress, and then the survival rate, the histology, the Na⁺/K⁺-ATPase (NKA) expression pattern and transcriptomic sequencing were investigated to evaluate the postlarval responses. The results showed that the postlarva survival rate in low-salinity water was only 61.11%, which is significantly lower than that for postlarvae reared in saline water (92.67%). However, taurine supplementation significantly increased the postlarva survival rate in low-salin
