Abstract

Barbus sharpeyi in family Cyprinidae is an endemic fish of the province Khuzestan of Iran. These fish
are produced by artificial breeding using carp pituitary extract (CPE). According to the problem of
artificial breeding about this fish in Iran, the objective of this study was to obtain the effectiveness new
method (LHRH-a2 hormone Combined with carp pituitary extract (3 injections) on reproduction index
in Barbus sharpeyi. The results showed that the LHRH-a2 hormone combined with carp pituitary
extract in three injection (specially treat2) lead to high spawning success (62% average) and weight of
stripped egg mass/ weight of stripped egg mass (8.49% average) and fertilization success (76.57%
average). Therefore, it can be concluded that like many other cyprinids, LHRH-a2 hormone combined
with carp pituitary extract (3 injection) can be effectiveness for spawning induction in Barbus
sharpeyi.
