Water Quality Assessment in The Occurrence of Acanthaster spp. (Crown-of-Thorns Starfish, CoTS) on Coral Reefs in Menjangan Island, Bali, Indonesia
Aquatic stressors are known to cause biological impairment that can result in biodiversity loss in several Marine Pro-tected Areas (MPA), including in Menjangan Island, West Bali National Park. The objectives of this study wereto cor-relate the changes in water quality parameters with...
