ABSTRACT Information o n important and economic grouper fish (Serranidae family) in Peukan Bada waters, Province of Aceh is very limited . This objecives of this research w ere to determine spatial and temporal variabilit ies in species composition and community structure of grouper landed in Peukan Bada, Aceh Besar D istrict . The research was conducted using survey method during February to June 2015 on three fish landing sites i.e., Ujong Pancu, Lamtengoh , and Lamteh. The groupers w ere caught by using handline. The landed fishes were therefore counted and identified up to species level. The data were also analyzed based on taxonomic information and individual number of each species, community structure using the diversity index (H’), eveness (E), and dominance (D). The results obtained 835 individual, 21 species of grouper belong to 4 genera ( Aethaloperca , Cephalopholis , Epinephelus dan Variola ). Based on species, Epinephelus fasciatus and Cephalopholis sonnerati were the most grouper fishes in the region. Based on community structure , diversity value (H’) in Lam - tengoh was higher than that in Ujong Pancu and Lamteh. Total grouper fish catches were not significantly different (P>0,05) among the three region. Meanwhile, total grouper fish cacthes were significantly different between seasons (p<0,05). The diversity species variation during five months of observation was affected by the differences in catches area, the condition of aquatic enviroment, and oceanographic con d ition. Keywords : Groupers, Peukan Bada, species composition, community structure
