Localized bleaching (a discrete white area on the coral) was observed in one of the main framework-building corals in Hawaii, Porites compressa. This study aimed to determine the degree of virulence of the lesion. We investigated the whole-colony effects by following disease progression through time and examining the effect of localized bleaching on coral fecundity. After two months, 35 of 42 (83.3%) individually tagged colonies affected by localized bleaching showed tissue loss and partial colony mortality. Histological slides of healthy P. compressa and samples from colonies showing signs of localized bleaching were compared showing that affected colonies had a significant reduction (almost 50%) in gamete development, egg numbers, and egg size in the affected tissue. The observed localized bleaching results in both partial colony mortality and a reduced number of gametes and was termed Porites Bleaching with Tissue Loss (PBTL).
