Abstract:
The effects of ovaprim and prostaglandine F2α (PG F2α) on semen volume and sperm quality in sepat siam (Trichogaster
pectoralis Regan) were observed. Eighteen wild cought male fishes were injected with three combinations of ovaprim and
prostaglandine F2α (0,250 ml ovaprim + 1250 μg PG F2α/kg body weight, P1), 0,375 ml ovaprim + 625 μg PGF2α /kg body
weight, P2), 0,125 ml ovaprim + 1875 μg PG F2α/kg body weight, P3), and two other individual hormones, ovaprim ( 0,50 ml
ovaprim/kg body weight, P4) and PG F2α (2500 μg PG F2α/kg body weight, P5), and control (1 ml NaCl 0.9%, P6). The best
result was presented by the combination of 0.250 ml ovaprim + 1250 μg prostaglandine F2α per kg body weight (P1), which
the semen volume, spermatozoa concentration, spermatozoa viability and spermatozoa motility were 0.163 ml, 18.167 x
109/ml, 81.50% and 79.833 % respectively.
