Spatiotemporal variation of harmful phytoplankton in recreational beaches in Campeche, southeastern Gulf of Mexico

The coastal waters of 6 recreational beaches on the coast of Campeche in the Gulf of Mexico were monitored from March to October 2019. Temperature, salinity, and pH ranges varied depending on the season and were likely influenced by the local hydrography and shallow depth of the study area. The harm...

Temperature, salinity, and pH ranges varied depending on the season and were likely influenced by the local hydrography and shallow depth of the study area. The harmful taxa identified in this study included 3 diatom, 5 dinoflagellate, and 2 cyanobacteria species, with abundances ranging from 102 to 105 cell·L–1. Within the phytoplankton community, phytoflagellates (nanophytoplankton <20 μm) exhibited a peak abundance of 1.6 × 106 cell·L–1 at Boca del Río in Champotón. Microphytoplankton (>20 μm), including diatoms, dinoflagellates, and cyanobacteria, were a secondary component with densities ranging from 103 to 106 cell·L–1. The dinoflagellate Pyrodinium bahamense, identified as toxic to humans on the Campeche coast, showed a maximum abundance of 2.0 × 105 cell·L–1 in May at Boca del Río. The toxic diatom Pseudo-nitzschia exhibited a peak abundance of 105 cell·L–1 at Payucan in May. The cyanobacteria genera Anabaena and Trichodesmium exhibited abundances ranging from 102 to 104 cell·L–1. Potentially harmful phytoplankton and cyanobacteria were present in all seasons and months, indicating that continual monitoring is needed to assess beach quality to ensure the safety of recreational beaches.  Se monitorearon las aguas costeras de 6 playas recreativas en la costa de Campeche en el golfo de México de marzo a octubre de 2019. Los rangos de temperatura, salinidad y pH variaron según la temporada y probablemente estuvieron influenciados por la hidrografía local y la poca profundidad del área de estudio. Los taxones nocivos identificados en este estudio incluyeron 3 especies de diatomeas, 5 dinoflagelados y 2 cianobacterias, con abundancias que oscilaron entre 102 y 105 cél·L–1. Dentro de la comunidad de fitoplancton, los fitoflagelados (nanofitoplancton <20 μm) exhibieron una abundancia máxima de 1.6 × 106 cél·L–1 en Boca del Río en Champotón. El microfitoplancton (>20 μm), incluidas diatomeas, dinoflagelados y cianobacterias, fue un componente secundario con densidades que oscilaron entre 103 y 106 cél·L–1. El dinoflagelado Pyrodinium bahamense, identificado como tóxico para los humanos en la costa de Campeche, mostró una abundancia máxima de 2.0 × 105 cel·L–1 en mayo en Boca del Río. La diatomea tóxica Pseudo-nitzschia exhibió una abundancia máxima de 105 cél·L–1 en Payucan en mayo. Los géneros de cianobacterias Anabaena y Trichodesmium exhibieron abundancias que oscilaron entre 102 y 104 cél·L–1. En todas las estaciones y meses se presentaron fitoplancton y cianobacterias potencialmente dañinos, lo que indica que es necesario un monitoreo continuo para evaluar la calidad de las playas y garantizar la seguridad de las playas recreativas.
