Abstract

Abstract: The objective of this work was to evaluate whether tetracycline (TC) in environmentally relevant concentrations was able to induce alterations to embryonic development and teratogenic effects in oocytes and embryos of Cyprinus carpio . For this purpose, an embryolethality study was conducted and the lethal concentration 50 (LC50 ) and effective concentration 50 of malformations (EC50 ) were calculated, and with these data the teratogenic index (TI) was determined. The main alterations to embryonic development and the teratogenic effects produced by TC on embryos of C. carpio were determined using the Kimmel and Hersem scale adapted for Cyprinus carpio . LC50 and EC50 were respectively 500.08 and 145.3 μg L −1 .TC was shown to be teratogenic with teratogenic index of 3.44, and the main malformations identified in concentrations of 90–900 μg L −1 were malformation in tail, modified chorda structure, pericardical edema, scoliosis and malformations of the heart. A significant decrease in concentration-dependent in Kimmel and Hersem score was observed. The results allow us to conclude that TC at environmentally relevant concentrations is capable of inducing embryotoxic and teratogenic effects, generating risk in the integrity of the common carp C. Carpio. Highlights: Embryotoxicity and teratogenicity induced by tetracycline on Cyprinus carpio was evaluated. The teratogenic index of tetracycline was 3.4. Tetracycline was embryolethal and teratogenic for oocytes and embryos of common carp. The main tetracycline malformations were malformation in tail, modified chorda structure, pericardical edema, scoliosis.
