Body condition of the coral-dwelling fish Dascyllus aruanus (Linnaeus 1758) following host colony bleaching



Coral bleaching and degradation often results in the depletion of abundance of many reef fishes. However, the effects of coral degradation on coral habitat dependent fishes are poorly understood. Hence, in this study we examine the sublethal effects of coral bleaching on the physiological condition of Dascyllus aruanus, an obligate coral-dwelling damselfish. The results of this study showed that fish associated with bleached coral habitat showed similar levels of hepatocyte vacuolation compared to individuals associated with healthy colonies.
