Abstract
Exposure to TEX-OE (R), a patented extract of the prickly pear cactus (Opuntia ficus indica) containing chaperone-stimulating factor, was shown to protect common carp, Cyprinus carpio L., fingerlings against acute ammonia stress. Survival was enhanced twofold from 50% to 95% after exposure to 5.92 mg L-1 NH3, a level determined in the ammonia challenge bioassay as the 1-h LD50 concentration for this species. Survival of TEX-OE (R)-pre-exposed fish was enhanced by 20% over non-exposed controls during lethal ammonia challenge (14.21 mg L-1 NH3). Increase in the levels of gill and muscle Hsp70 was evident in TEX-OE (R)-pre-exposed fish but not in the unexposed controls, indicating that application of TEX-OE (R) accelerated carp endogenous Hsp70 synthesis during ammonia perturbation. Protection against ammonia was correlated with Hsp70 accretion.
