Enhancement of Hypoxia Tolerance of Gibel Carp (<i>Carassius auratus gibelio</i>) via a Ferroporphyrin-Rich Diet.

ABSTRACT: Gibel carp (Carassius auratus gibelio) were hypoxia stressed for 12 h after an 8-week FPR nutrient-enriched feeding experiment, which was to evaluate the role of FPR in hypoxic stress in gibel carp (Carassius auratus gibelio). The dissolved oxygen was reduced to a range of 0.6 ± 0.2 mg/L. Results showed that FPR supplementation could maintain the osmotic pressure equilibrium by improving the ion concentrations of plasma including Na⁺, Ca⁺ and K⁺, and Na⁺/K⁺-ATPase activity of liver. FPR supplementation could effectively enhance the antioxidant capacity by improving the levels of GPX, SOD, CAT, and GSH, and reduce the level of MDA. FPR supplementation could improve the core gene expressions of Nrf2 signalling pathway inclu
