Efecto del pH sobre la supervivencia embrionaria, periodo embrionario y de eclosión de Galaxias maculatus

This study aims to evaluate the effect of pH on embryonic survival of Galaxias maculatus. Embryos were incubated at 6 different pH levels in the water. One-way ANOVA was used to compare averages between treatments and Tukey test to determine post hoc differences. The Probit regression was used to es...
