Transport of Astyanax altiparanae Garutti and Britski, 2000 in saline water
Acta Scientiarum: Biological Sciences, 2015 Two experiments were performed. The first aimed to assess the tolerance of fingerlings Astyanax altiparanae to water salinity. Fish were exposed to salinity of 0, 3, 6, 9, 12 or 15 g NaCl L-1 for 96 hours. The fish mortality was 0%, in the levels of 0, 3
