Blanakan coast is known as prominent fishing ground in West Java coastal ecosystems. This is related to the presence of suitable habitat for fish species living in coast. One of fish species known living in Blanakan coast and has commercial value is Leiognathus splendens . Respectively, this research aims to predict the suitable habitat for L. splendens by using environmental parameters including salinity, ph, dissolved oxygen (DO), temperature, turbidity and Zn. The habitat suitability estimation method used was the ranking and overlay of environmental parameters. Those parameters were combined and overlayed by using geographical information system assistance to identify the most suitable habitats. Based on the result, the most suitable habitats were located near river mouth. This habitat is influenced by high level DO (5.7 mg/L) and pH (7.51). Correspondingly, the suitable habitats near the river mouth considering that L. splendens has an adaptation to low salinity (9 ppt) and high turbidity (218.03 NTU) near river. In contrast, the less suitable habitats were identified offshore. In here, the habitats affected by high temperature (31 °C), Zn content (0.55 mg/L), low DO (1.1 mg/L) and pH (7.15). This research hence might contribute some potentially valuable insights into exploring the relationship between the L. splendens suitable habitats and the environmental parameters.
