Seagrass ecosystem has a vital role in the marine environment as a habitat for marine biota, primary productivity, regulate the trophic level of species and populations and gas regulations for the balance of CO2 and O2 through the photosynthesis of mechanism. The purpose of this study is to analysis the ecology of seagrass (seagrass conditions, threat of damage to seagrass, the abundance and diversity of fish species), the social aspect (local ecological knowledge and community values local knowledge). Data was collected by survey and observations. Data analysis was conducted descriptively to explain the condition, potential threats and sources of damage to the seagrass and regression models was used to explain the number of species and aossociation of fish to seagrass. These results indicate the condition of seagrass at the study site in the category of normal, the number of seagrass species was nine species of the total area of 154.21 ha of the seagrass and seagrass community types was a mixed type. Type and number of fish species obtained from 42 families comprising 118 species and 16 049 individuals. The most fish appropriate regression model to explain the number of species and individual fish associated with seagrass is quadratic and exponential models. Fish species diversity is the highest in Gili Maringkik (2.942) and the lowest is in Gili Kere (2.448). Seagrass damage parameters can be seen from the status of marine species such as the scarcity of fish, sea cucumbers, shrimp and molluscs as well as the number of damaged seagrass biomass/day by the community. Ecological communities have sufficient knowledge to know seagrass species as well as the function of the environmental and economic benefits to society and have the local knowledge that is relevant to the conservation namely awiq-awiq. The conclusion of the study is the management of the seagrass beds to the sustainability of fish can be done through seagrass conservation strategy with the zoning system through : (1) integrate the existence of ecology as an instrument in the management and the conservation design, (2) accommodate the ecological knowledge and indigenous communities and (3) zoning can be made in the management of the core zone in the seagrass zone the Gili Kere and sustainable fisheries in the seagrass beds in other locations.
