Abstract

The migratory species piabanha does not reproduce in lentic environments since it requires environmental stimuli for the maturation and extrusion of gametes, and therefore hormonal induction is mandatory. Current study compares the seminal characteristics of Brycon insignis without any hormonal induction (Control - Ctrl) and with two types of hormonal inductors, or rather, carp pituitary extract (T1 - 2.5 mg kg^-1 body weight) and GnRH analogues, the latter applied in two different concentrations (T2 - 0.7 mg kg^-1 body weight and T3 - 1.4 mg kg^-1 body weight). Post-induction analyses showed that the hormones increased the motility rate - Ctrl (95%), T1 (100%), T2 (100%) and T3 (98%), although sperm concentration - Ctrl (11.52 x 10⁹); T1 (4.37 x 10⁹); T2 (4.34 x 10⁹); T3 (4.01 x 10⁹) decreased. Assessments for sperm vigor, motility time and spermatic morphology did not vary with hormonal induction. Hormonal inducer does not alter negatively the seminal characteristics of the piabanha, and the choice for the proper hormone depends on the preference of the dispenser.
