Abstract

Coral disease is a significant factor causing the degradation of Karimunjawa coral reefs. The objective
of this study was to determine the possible effects of nutrient enrichment, released by floating cages
used for fish culture, on the coral disease outbreak in Karimunjawa National Park, Java Sea. The islands
of Genting, Sambangan, and Seruni were selected as study sites as they represent islands with human
habitation and a high intensity of mariculture activity, no human habitation and a high intensity of
mariculture activity, and no human habitation or mariculture activity, respectively. The results show
that the prevalence of coral diseases in Genting, Sambangan, and Seruni were significantly different
(p < 0.01). However, there was no significant correlation between the nutrient concentrations (N and
P) and coral disease prevalence (R
= 0.42; p = 0.058 for
phosphate). The nutrients on the islands affected by marine fish cages tended to increase. We suggest
that the continuation of orderly ecosystem monitoring, with increasing sample sizes, in Karimunjawa
is urgently needed.
