The aims of this paper were to explore lobster resources and its exploitation at the southern coastal of Yogyakarta. Capture fisheries could be categorized as new activity for fisherman. Fisherman was a farmer that historically does not have large dependent root towards marine capture fisheries. Although the harvesting in small number, lobster is main species target, especially for the fisherman in Gunungkidul. This species gives a real contribution towards changing of the fisherman social economy as shown by housing promotion into permanent housing of ceramic floor. Although six species has been found, P. penecillatus and P. homarus dominant lobster catch, account for 57.18% and 31.37%, respectively. Gonad stages and fecundity were varying at area of research. Mature Lobsters from Fish Market (TPI) Baron and Fish Market (TPI) Sadeng were around 31.3-44.9% (except P. longipes) and 21.7-37%, respectively. The fecundity of P. penicillatus was 45,124–249,316 eggs, while P. homarus and P. longipes were 51,725-111,389 eggs and 91,966 eggs, respectively. MSY lobster around Baron was 7,155.19 kg/year with level of exploitation above its TAC. The fishing ground that limited only in the coastal zone and less effort of conservation will lead to the degradation of stocks in the future. The integrated policy and management and the participatory of local community are needed to avoid the tragedy of the commons.
