This study aims to evaluate the effect of temperature and salinity on Galaxias maculatus embryo survival. Embryos were incubated at 5, 10 and 15 degrees C and 0, 10 and 30 psu. At 5 degrees C all salinities induced 100% mortality. Furthermore, salinity of 30, regardless temperature, caused 100% m...

Combined effect of temperature and salinity on embryonic survival of 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...

Effect of pH on embryonic survival, embryonic and hatching period of Galaxias maculatus
The use of antifungals was assessed to improve embryo survival of Galaxias maculatus. Three treatments using formalin dose of 250 ppm, iodine dose of 100 ppm, and sea salt in doses of 30 ups were designed, and a control treatment under 10 of salinity water. For each treatment and control, 15 repl...

Embryonic survival of Galaxias maculatus (Jenyns, 1842), under different prophylactic immersion bath
We evaluated the effect of six constant temperatures on embryonic survival, embryonic period and hatching period of Galaxias maculatus from 7 to 22 degrees C under laboratory conditions. The results of embryo survival were: 90.6 +/- 2.0, 88.7 +/- 8.6, 87.7 +/- 0.7, 89.7 +/- 4.2, 70.0 +/- 5.6 and ...
