Recruitment of Porites (Scleractinia) on artificial substrate in reefs affected by the 1997–98 El Niño in Banderas Bay, Mexican Pacific

Mexican Pacific coral reefs were severely damaged by the sea surface warming observed during the 1997–98 El Niño. In Banderas Bay, massive coral mortality was as high as 97%, and the surviving colonies were exposed to sublethal temperatures and thermal stress. In this coral recruitment study we atte...

In Banderas Bay, massive coral mortality was as high as 97%, and the surviving colonies were exposed to sublethal temperatures and thermal stress. In this coral recruitment study we attempted to estimate the recovery and potential repopulation of corals in the Mexican Pacific. After the El Niño event, we used terracotta tiles to monitor the settlement of coral larval propagules at nine reefs in the region. The recruitment study took place from December 1998 to July 1999. Settlements of nine specimens of Porites were recorded at two localities. This is the first settlement record for this coral genus in the eastern tropical Pacific and the one with the largest number of specimens recruited during a study involving artificial substrate. The results indicate that these reefs do not totally depend on the arrival of allocthonous coral propagules from other regions of the tropical Pacific to maintain their development. This study also shows that corals maintain their reproductive activity despite the environmental disturbances. Therefore, sexual reproduction of reef corals of this region provides an effective alternative for the recovery of Mexican Pacific coral reefs. Los arrecifes de coral del Pacífico mexicano fueron severamente dañados por el calentamiento del agua ocasionado por el evento El Niño 1997–98. En Bahía de Banderas, la mortalidad alcanzó 97% de cobertura de coral en algunos arrecifes, y las colonias sobrevivientes estuvieron expuestas a temperaturas subletales. El presente estudio de reclutamiento coralino se llevó a cabo con el objetivo de estimar la recuperación y repoblamiento de los corales escleractinios en esta región del Pacífico mexicano. Después del evento El Niño se utilizaron losas de barro para monitorear la fijación de los propágulos larvales de coral en nueve arrecifes de Jalisco y Nayarit (México). El estudio se realizó desde diciembre de 1998 hasta julio de 1999, y se encontraron nueve ejemplares de Porites fijados sobre el sustrato artificial de dos localidades. Este hallazgo representa el primer registro de este género y el mayor número de ejemplares encontrados en un estudio de reclutamiento con sustrato artificial en el Pacífico oriental tropical. Las localidades donde se hallaron los reclutas de coral presentan características que comprueban que los arrecifes del área de estudio no dependen totalmente de la llegada de propágulos originados en otras regiones del Pacífico. Asimismo, se demuestra que los corales mantienen su actividad reproductiva a pesar de las perturbaciones. De acuerdo con las circunstancias, la reproducción sexual es una alternativa efectiva para el repoblamiento de los arrecifes de la costa mexicana.
