ABSTRACT :

The prevalence of coral disease was previously unreported on the reefs of the Padang Shelf Reef System, West Sumatra and is relatively uncommon. The objective of this study was to get coral disease prevalence of each site which located at inshore, mid-shelf reef and off-shore reefs. The research was carried out by using belt transect method with 1 m left and right of tape as long 30 m with 3 replications. Two kinds of coral disease and two indicators of stressed coral were observed. While relatively infrequent, Black Band Disease was most common (1.3%) occurring on Pandan Island at 5m. White Syndrome occurred at Air patch reef (0.3%). A few Bleached colonies of Montipora sp and Pocillopora verrucosa ware observed on Pieh Island reef (2.1%). Focal Bleaching in was observed on Galaxea sp and Goniastrea sp at Gabuo patch reefs (2.5%) and on Pocillopora verrucosa at Sipakal patch reef (3.9%). BBD infected both Montipora sp and Porites sp. WS only infected on Montipora sp. Montipora, Pocillopora and Porites were the most common genera observed on the reefs. Infeksi penyakit karang di kota Padang masih tergolong rendah dan secara alamiah bisa terjadi sehingga tidak perlu dikuatirkan akan menghalangi proses pemuliahan kondisi karang yang saat ini terjadi dan secara umum pada status kesehatan karang.
