Low water hardness and pH affect growth and survival of silver catfish juveniles

The objective of this study was to investigate the effects of exposure to low water hardness (0, 25 and 50mg CaCO 3L -1) into the 6.0-8.0 pH range to silver catfish juveniles (Rhamdia quelen) survival and growth after 32 days. Juveniles kept at zero water hardness presented higher mortality at pH 7....

Juveniles kept at zero water hardness presented higher mortality at pH 7.0 and 8.0 than those submitted to other treatments. Weight of juveniles exposed to pH 6.0 and zero water hardness was significantly higher than those kept at the same water hardness and other pH. Survival and growth of juveniles exposed to 25 and 50mg CaCO 3L -1 was not affected in the 6.0-8.0 pH range. Therefore, the best water hardness for silver catfish juveniles growth is 25-50mg CaCO 3L -1 and at low water hardness (next zero) pH must be reduced. 2020-05-31T18:05:39Z 2020-05-31T18:05:39Z 2011 Artigo https://repositorio.inpa.gov.br/handle/1/16189 10.1590/S0103-84782011005000101 pt_BR Volume 41, Número 8, Pags. 1482-1487 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Ciência Rural
