Tissue-specific expression responses of antioxidant, immune, and metabolic genes in juvenile yellowfin tuna ( Thunnus albacares ) under acute low-pH stress
Acute reductions in seawater pH may disrupt acid–base regulation and physiological homeostasis in marine fish, but tissue-specific molecular responses in juvenile yellowfin tuna remain poorly understood. Juveniles of yellowfin tuna were exposed for 48 h to four seawater pH levels (8.1, 7.6, 7.1, and 6.6), with three re...
