Abstract

Preliminary surveys for coral disease were conducted in October 2011 as part of the first Indonesian coral health workshop in Barranglompo Island, part of the Spermonde Islands, South Sulawesi, Indonesia. Previous coral disease surveys conducted in Wakatobi National Park (WNP), South-East Sulawesi in 2005 and 2007, and qualitative surveys in April 2011, are included here to provide an overview of what is known about coral disease in Sulawesi and to compare results with reports from other regions of the world. On all reefs surveyed in these two locations, levels of coral disease were relatively low compared with global averages from other locations. In preliminary surveys of Spermonde reefs, the most significant syndrome detected was white syndromes, which affected 13 different coral genera. The most significant syndromes detected in WNP were white syndromes, black band disease, and a yellow tissue discoloration syndrome that was similar macroscopically to Caribbean yellow band disease. Although overall coral disease prevalence was low in Barranglompo and WNP, there is the potential for greater impacts of coral disease as anthropogenic influences increase and the oceans continue to warm. This study provides preliminary baseline data on the impact of coral disease within the reefs of Sulawesi, Indonesia, the center of coral reef biodiversity.

Abstract

Fertilization and larval development determine the coral population survivalof species, which has adifference characteristic of embryogenesis. This research wasaimed to compare the embryo and larvaldevelopment spawned in November 2011 in Grear Barrier Reef, Australia.Embryonic cellsdevelopment wereobserved in interval timesfrom one cell of egg tomulticellular stage (prawnchip), and larval developmentobserved from the prawnchip stageto the planulae.The results showed the development of embryos and larvaesignificantly differed between two species, i.e. embryos and larvae of Acropora millepora grew faster thanA.tenuis. The maximum size of planulae larvae of A. millepora (800-1000 μm) is biggerthan A. tenuis (650-900μm). Embryo and larvae development were different due to species variability, hence this reseach can beadapted for laboratory proccess of coral larvae nursery. Keywords: embryo, planulae, Acropora millepora, A. Tenuis
