Indonesia is the largest archipelagic state with very complex oceanography. The bio geography of the state is really diverse. Information of the distribution of marine organisms is necessary for their management. The management of Indonesian fisheries resources has been set into 11 State Republic of Indonesia fisheries management areas (WPPNRI). East Java Province is in 2 management areas, namely WPPNRI 712 in theNorth (Java Sea) and WPPNRI 573 in the South (Indian Ocean). One of the priority resource groups in management is lobster fisheries. Lobster is known as a fishery commodity with very high economic and ecological value. This study aims to identify dominant lobster species of East Java which will be used as study indicator for management of the lobster fisheries. Data collection was carried out in the largest lobster collectors and distributors in East Java. Data analysis was performed using Chi Square and ANOVA (Analyses of Variance). Dominant lobster species in the North Sea are Panulirus polyphagus (Udang Pakistan) and P.ornatus (U. Mutiara) while the South Sea is P. homarus (U. Pasir) and P. penicillatus (U. Batu).
