Abstract.-During a restoration process of Pocillopora spp., using opportunity corals (CO) several biotic attributes were assessed at two sites bi-monthly over a year and concentrations of mycosporin type amino acids (MAAs) and levels of chlorophyll a (Chl a) were determined. Specifically, in the last sampling analysis it was performed an analysis of malonaldehyde (MDA) and the RNA/ DNA and protein/DNA relationships were calculated, as an index of oxidative stress and transcriptional activity in symbiont and coral tissue of all morphotypes. At Carrizales site (SC) the coral clusters (RC) used as a method of restoration, promoted the integration of CO showing signs of recovery and high survival rates (90%); however, in Juluapan site (SJ), a lack of response to biotic and molecular indicators associated with recovery was observed. Therefore, CO from Carrizales were not able to acclimate to a place where different conditions prevail. High concentrations of Chl a, AAMs and a high RNA/DNA ratio were characteristic of a healthy condition of coral which in turn, were associated with higher specimen's survival and restoration.Key words: Restoration, Pocillopora, calcareous algae, coral, oxidative stressResumen.-Durante un proceso de restauración de Pocillopora spp., usando corales de oportunidad (CO), fueron evaluados diversos atributos bióticos en dos sitios a lo largo de un año, de manera bimensual fueron determinadas las concentraciones de aminoácidos tipo micosporina (AAMs) y niveles de clorofila a (Cl a). De manera específica, en el último muestreo se realizó un análisis de malonaldehido (MDA) y se calcularon las relaciones ARN/ADN y proteína/ADN como indicadores de estrés oxidativo y actividad trascripcional en simbionte y cnidario de todos los morfotipos. En sitio Carrizales (SC) la técnica de restauración de ramilletes coralinos (RC) promovió la integración de COs registrando signos de recuperación y altas tasas de supervivencia (90%); no obstante, en el Sitio Juluapan (SJ), se observó una falta de respuesta a los indicadores bióticos y moleculares asociados a la recuperación. Por lo tanto, los CO provenientes de Carrizales no fueron capaces de aclimatarse a un sitio en el que imperan distintas condiciones ambientales. Altas concentraciones de Cl a, AAMs, y una alta relación ARN/ADN fueron características de una condición saludable de corales, que a su vez, estuvieron asociados a los indicadores de restauración y mejor supervivencia observada.
