Horizontal Distribution of Zooplankton in Tangerang Coastal Waters, Indonesia

Abstract Zooplankton plays an important role in aquatic ecosystems. It has both horizontal and vertical distribution. This research was conducted in Tangerang coastal waters with the purpose to determine horizontal distribution of zooplankton and its correlation to water quality. The results showed that there were 12 groups of zooplankton found in Tangerang coastal waters dominated by Crustacean. Based on Morisita Index, zooplankton in Tangerang coastal waters has been grouped as patchy pattern distribution. Horizontal distribution of zooplankton was divided into two clusters of site location and more influenced by pH and ammonia.
