Phytotherapy has been used in fish breeding to promote stability in the cultivation environment and in the proflatic management reflecting on animal heath. Erythrina crista-galli has a sedative effect and antioxidant and antimicrobial activity, besides functioning as a natural tranquilizer. In the absence of formulations for use in cultivated fish, therapeutic protocols emerge without studies that reveal their characteristics and actions in the animal organism. Therefore, this study evaluated the effects of acute exposure of Carassius auratus to Erythrina crista-galli extract evaluating the physiological blood parameters. In the acute tolerance assay of Erythrina crista-galli, specimens of Carassius auratus were used, exposed to control concentrations (zero), 50, 100 and 200 mg L-1, with three replications, for 96 hours. Survival of 100% was observed in all treatments. These results reveal that the extract of Erythrina crista-galli does not present toxicity to this species of fish. The plasmatic electrolytic balance showed no changes. The use of up to 100 mg L-1 did not promote changes in gaseous exchanges. The pH and the concentration of bicarbonate and glucose were increasing until the concentration of 100 mg L-1. It is concluded that the use of Erythrina crista-galli for acute exposure of Carassius auratus does not promote mortality, but causes undesirable alterations in blood physiological parameters when doses above 100 mg L-1 are used.Keywords: Herbal medicines.
