Gonad development in 54 Acipenser persicus and Huso huso sturgeon fish is described. Mean oocyte diameter of
A.persicus at 1, 2 and 6 years was 11.9±2.6,
111.7±31 and 144.9±44.9µ and Huso huso 10.9±2.5, 147.7±24.4 and 163.6±20.8µ,
respectively. Mean sac sperm diameter in A.persicus was 13.8± 2.4µ, 34.2± 11µ and
54.2±21µ and Huso huso
14.5±3.9µ, 43.8±9.4µ and 94.3±54.1µ, respectively. Histology suggested that 6 year old A. persicus are in stage II of sexual maturity and the
size of oocytes and number of sperm increases during the stages of sexual
maturation. The results suggest that differences in reproductive development
and environment may account for structural differences in gonads of various
species.
