The freshwater contains a variable amount of dissolved salts, depending on the soil in which
it occurs. Water acidification may occur in places where the soil has acidic cations and water …

The freshwater contains a variable amount of dissolved substances, depending on the soil
in which it occurs. Most teleosts species survive to acute pH changes down to water pH 4.0 …

Although fish may live in different aquatic environments, variations in the water quality
parameters, mainly pH, may have a substantial impact in their development and welfare …

The objective of this study was to investigate the effects of exposure to low water hardness
(0, 25 and 50mg CaCO3L-1) into the 6.0-8.0 pH range to silver catfish juveniles (Rhamdia …

The relationship between water pH and hardness influences fish physiology, where
increasing water hardness could trigger a protective effect for fish exposed to acidic or …

The article presents a study which discussed the interaction of water alkalinity and stocking
density on the survival and growth of juvenile silver catfishes. According to the author …

Theaim of this study was to examine the survival of fingerlings of silver catfish, Rhamdia
quelen, in water with different pH and hardnessvalues. Fingerlings (1.60±0.14 g; 5.67±0.15 …

Water hardness varies regionally and optimal levels for fish are often species specific. It is
generally assumed that largemouth bass, Micropterus salmoides, require elevated water …

A total of 468 silver catfish juveniles were obtained from the fish culture Bela Vista in Santa
Maria, in Southern Brazil. These juveniles were transferred to the Fish Physiology …

Eurihaline fish support waters with different salt concentration. However, numerous studies
have shown that salinity can affect fish development. Thus, the effect of salinity change from …
