Abstract

Morphological development and allometric growth patterns of reared Persian sturgeon, Acipenser persicus, were studied from hatching to 50 days post-hatching (dph). The larvae weresampled, their left sides photographed and seven morphometric characters, including total length, head length, tail length, trunk length, snout length, caudal peduncle and predorsal length weremeasured. Allometric growth patterns were calculated as a power function of total length anddescribed using the growth coefficient to find important steps in early life history. The total lengthof the newly hatched larvae and fry were 10.59±0.8 and 38.8±2.9 mm at 1 and 50 dph, respectively.Morphogenesis and differentiation were the highest rates during the first 11 days of earlydevelopment, i.e. endogenous feeding period. There were higher growth rate of head, snout and tailregions compared with those of other organs from the hatch up to yolk sac absorption, followed bypositive or almost isometric patterns, after the begin of exogenous feeding, showing priority toenhance the feeding and swimming capabilities. This study confirmed that most of morphologicalchanges of this species are occurred from hatching until the onset of exogenous feeding i.e. duringthe lecithotrophic phase.
