Abstract

Research on species composition and size pony fish was carried out from August 2009 to Juny 2010 at three stations in Kendari Bay, Southeast Sulawesi. Fish collection was done experimental gillnets (with different mesh sizes ¾, 1, 1¼, 1½, and 2 inch) ) and seser (Ø 1 meter and mesh size 0.04 inch). Ten species of Leiognathidae families were collected during research. There was three genera of  Leiognathidae namely Gazza (1 species), Leiognathus (7 species) and Secutor (2 species). Based on number of fish, N. blochii (39.72%) and L.splendens (33.95%) were dominant species on Station I (39.72%), S. indicius on Station II (38.75%), and N. blochii (20.50%) dan L.splendens (25.10 %) on Station III (25.10%).  Based on frequency of occurrence during study, L.splendens was resident species (100%), while P.bindus and L.dussumieri were rarely (18.18%).  Based on size range and frequency of occurrence of fish, indicated pony fish used of Kendari Bay as nursery ground.
