Abstract
Based on oceanographic survey data in June 2012 in the Lembeh Strait, the zooplankton ecological characteristics such as species composition, individual abundance, dominant species and distribution were analyzed. The results showed that 183 species (including 4 sp.) had been recognized, most of them belonged to copepoda. Cnidaria followed with 43 species (including 1 sp.) were identified. The average abundance of zooplankton was (150.47±58.91) ind./m3. As to the horizontal distribution, the abundance of the zooplankton was higher in the southern waters than in the northern waters. The dominant species in the study area were Lensia subtiloides, Sagitta enflata, Lucifer intermedius, Oikopleura rufescens, Diphyes chamissoni, Creseis acicula, Subeucalanus subcrassus, Temora discaudata, Aglaura hemistoma, Doliolum denticulatum, Canthocalanus pauper, Oikopleura longicauda and Nanomia bijuga. Zooplankton biodiversity indexes were higher in study area than previous study in the other regions. The findings from this study provide important baseline information for future research and monitoring programs.

1 Introduction Coral reef ecosystems were composed by several interdependent communities and habitat niches. Zooplankton, which was an important community in the coral reef ecosystems, was a necessary food source for corals and other reef organisms. (Tada et al., 2003; Ferrier-Pagès et al., 2011). Zooplankton also plays a key role in marine food web dynamics, biogeochemical cycling and fish recruitment (Alcaraz et al., 2010). They also play an important role in the biomagnifications of pollutants of food webs (Gray, 2002). Zooplankton affected the health, growth, and survival of corals by several ways. They can be able to influence the physicochemical characteristics of the water column by absorption, transformation and elimination (Fisk et al., 2001). Disturbances such as a decrease of corals and increase of nutrients from human activities may influence the structure of zooplankton communities by changing the quantity and composition of food sources (Houlbrèque and Ferrier-Pages, 2009). At the same time, as to the sensitivi
