Effect of timing of hormonal induction on reproductive activity in lambari (Astyanax bimaculatus)
Theriogenology, 2012 The objective was to evaluate the influence of the timing of hormonal induction, using gonadorelin or common carp pituitary extract (CPE), on the reproductive activity of female Astyanax bimaculatus. Fish (N = 44) were weighed, measured, and acclimatized to experimental conditions with a photoperiod of 12 h:12 h light:dark (L:D) for 10 days.
