Seven sea turtles were released in the town of Mazunte, in the state of Oaxaca, in southern Mexico, after receiving rehabilitation due to severe poisoning suffered by red tide at the end of last year, authorities of the National Commission of Natural Areas reported Protected (CONANP).
They were six specimens of brown turtles ( Chelonia mydas ) and a golferina ( Lepidochelys olivacea ), which were treated at the Mexican Tortoise Center (CMT) “for having ingested salpas during the presence of red tide in the region between Salina Cruz and Puerto Escondido”, in the same entity of Oaxaca, according to the center.
At the end of December 2019, the CMT received more than a dozen specimens of turtles, mainly golfinas ( Lepidochelys olivacea ) and prietas ( Chelonia mydas ). All showed signs of intoxication and through analyses performed, it was confirmed that this happened due to the phenomenon known as red tide.
And on December 25, this phenomenon occurred on the Oaxaca coast, caused by the increase of microalgae in the water. The next day, the CMT performed the necropsy of two specimens of turtles found dead on the beaches of Huatulco, and determined the cause of death: poisoning by salpas (trematode) that paralyze the turtles.
In total, 292 sea turtles died, which were found on the southern shores of the Mexican Pacific. Volunteers, researchers and authorities saved 27 turtles, which were transferred to the Center for rehabilitation.
