Due to the “Red Tides” monitoring program, the presence of algae growth that causes it has been detected, creating what is known as the “Green Tide”; a risk to the population.

As mentioned by researchers from the University of Guadalajara, from the University Center of the Coast, based in Puerto Vallarta; It has been detected with a greater presence in Yelapa, municipality of Cabo Corrientes and in the Marietas Islands National Park, in Nayarit.

The Master of Science María del Carmen Cortés Lara, assured that for five months, they have been monitoring the blooming of algae, within the Bahía de Banderas, explained that thanks to the “Red Tides Monitoring Program” of Bahía de Banderas-CUCosta-UdeG , which has been carried out since 2000, has a historical database and record of scientific activities related to algal blooms.

The researcher assured that so far this year, they have detected 4 to 6 blooms of algae, better known as "red tide," caused by different species in the Bay.

“During the month of May, we observed a bloom of algae, but now as a “green tide”, and in the laboratory we have identified the microalgae (Eutriptiella), creating a quite considerable stain; which is why it is important for the population in general to take precautions,” warned teacher Cortés Lara.

In this regard, he recommended avoiding swimming in areas where the patches are seen, that is, where a higher concentration of this microalgae is observed, or where dead fish are observed, floating.

In addition, it is important that the general population does not collect fish from the sea, much less consume them. Also do not give them to pets, as food. Researchers have observed people collecting fish around the bay for food; however, it is not suitable for human health.

The "green tide" has currently been observed south of Banderas Bay, especially off the coast of Yelapa, municipality of Cabo Corrientes, where it has been for about a month. Although also, in front of the Marietas Islands National Park.

That is why the researchers at the University Center will continue with the monitoring work.
