摘要：Coral diseases are increasing throughout the Karimunjawa archipelago because of localanthropogenic stressors concomitant with alterations in coral cover. The present study was carriedout to quantify the indicators of coral cover and Acroporid White Syndrome (AWS) prevalence incruise line waters. The coral cover was calculated based on an Underwater Photo Transect (UPT)survey. Prevalence of AWS was determined by calculating the amount of Acroporid coral affectedby AWS disease divided by total coral colonies per 50 m2 transect quadrant. Results of the studyshowed that 98 out of a total of 1686 coral colonies were affected by AWS diseases. Prevalenceof all AWS diseases observed was 4.99 ± 3.11% SE. There was no significant difference betweencoral disease prevalence in the cruise line and non-cruise line areas (P-value = 0.667, >0.05).However, a significant difference was found among site locations (P-value = 0.001, <0.05). Therewas a highly significant correlation between the percentage of coral cover and AWS prevalence(r = 0.775; P-value = 0.004). Although statistically not significant, a higher prevalence of diseaseswas observed in sites with a close proximity with to shipping lines. More extensive monitoringon several islands with longer intervals are recommended in the shipping routes. The increase ofcoral cover might be resulting in the high prevalence of coral disease occurrence.
