Abstract: 

This research was conducted to study the body shape changes and morphological development of spare Sobaity (sobaity sea bream) (Sparidentex hasta), a valuable economical species, during early development from hatching up to 35 days post hatching (DPH) using geometric morphometric technique. A total number of 531 larval specimens were collected from different days. For extracting body shape data, the left side of specimens was photographed. Then nine homologous landmark-points were defined and digitized on 2D pictures using tpsDig2 software. Landmark data after GPA, based on procreates analysis analyzed using Relative Warp. The results showed that change of body shape in spare Sobaity during early development includes increasing depth and length of head, development of caudal region and increasing body depth, respectively. The cluster analysis was performed based on body shape of larval specimens using Ward’s algorithm, to identify clusters between age or size groups and the results revealed that larval stages of Sobaity can be divided into five stages including (1) early larvae, (2) larvae, (3) post larvae, (4) younger juvenile and (5) juvenile. Also, based on our finding, the body shape changes of this species during early development is due to adjusting of vital priority.
