Abstract

In this study, the effects of hormonal treatments on egg mortality after fertilization in Chilean flounder were evaluated. In the control group, plasmatic estradiol-17β showed very low levels before spawning induction. However E₂, GnRHa and GnRHa/bGH treatments caused high plasma E₂ levels resulted in poor egg survival. Probably, the persistent high E₂ levels affected the timing of oocyte maturation.
