Abstract

Objective of the study is to elucidate phenotype characters of nile tilapia (Oreochromis niloticus) of the third generation (G3)resulted from the selection breeding program in the Research Institute for Freshwater Aquaculture Bogor. Phenotypes of seventeen nile tilapia families, were observed using truss morphometric methods. The results showed that the composition average of standard lenght has low coefficient variation mean (10.42%) as well as coefficient variation of the truss measured characters (4.3- 13.3%). The highest index similarity of boddy shape within family was found in family 5 (79.3%), in contrast the lowest was in family 12 (32.3%). For index similarity between families, the highest score was in between family 12 and 17 (22.6).There were 8 characters enabled to differentiate the 17 families observed. They were Al, A3, A5, B2, C3, C5, C5, and D4. Cluster analyses recognized into 4 groups based on the phenotypic distance
