Red Tide Begins in March

The season for red tide (marea roja) in Mazatlán has already begun with sightings of the microalgae concentrated in the waters off El Faro lighthouse hill.

Investigator Roberto Cortez commented that the marine phenomenon can be seen in waters off Mazatlán shores during the month of March into early April and again in October.

It is a natural occurrence, he stated, and presents no risks. Most of the microalgae are beneficial to marine life, he said, but there are some species that contain toxins. If clams, mussels or other bivalves absorb the toxins and the shell fish are sold commercially, it could affect the consumer but it would depend on many conditions, he added.
