Abstract: Zebrafish (Danio rerio) is a well-studied laboratory model, because it has important genetic characteristics and translucent eggs. In this sense, new techniques are necessary that increase egg survival rate and hatchability. Thus, the objective of the study was to test baths of potassium permanganate and salt on Zebrafish eggs and observe the probability of hatching of each treatment. Statistical analysis was performed by means of Bayesian comparisons of means, and the hatch response variable followed a Binomial distribution (Y|θ~Bin(n,θ)), that is the observed value of hatched larvae with hatch probability. It was analyzed that the treatments that went through the bath with these compounds, showed less hatching in relation to the control, showing that the compounds were harmful to the embryonic development of the animals.
