Na+ and K+ body levels and survival of fingerlings of Rhamdia quelen (Siluriformes, Pimelodidae) exposed to acute changes of water pH. Níveis corporais de Na+ e K+ e sobrevivência de alevinos de Rhamdia quelen (Siluriformes, Pimelodidae) submetidos a variações agudas do pH da água.
The objective of this study was to investigate the effect of water pH on survival and Na+ and K+ body levels of fingerlings of Rhamdia quelen, a freshwater catfish. Survival was 100% at pH 4.00 to 9.0 throughout the experiment (96h), and death of all fingerlings was observed only at pH 3.75 or lower...
