Última Dissolved oxygen and ammonia levels in water that affect plasma ionic content and gallbladder bile in silver catfish Ciência Rural Becker,Alexssandro Geferson; Garcia,Luciano de Oliveira; Kochhann,Daiani; Gonçalves,Jamile Fabbrin; Loro,Vania Lúcia; Baldisserotto,Bernardo. Ionic contents (Na+, K+ and Cl-) of plasma and gallbladder bile (GB) of juveniles silver catfish, Rhamdia quelen (156.1±0.2g, 28.2±0.3cm), were determined in three different times (0, 6 and 24h) after exposure to: a) control or high dissolved oxygen (DO = 6.5mg L-1) + low NH3 (0.03mg L-1); b) low DO (3.5mg L-1) + low NH3; c) high DO + high NH3 (0.1mg L-1); and d) low DO + high NH3. High waterborne NH3 or low DO levels increased plasma and GB ion levels. These parameters might have followed different mechanisms to affect osmoregulation since a synergic effect of these variables was detected.

Ano: 2009 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782009000600020 Low water hardness and pH affect growth and survival of silver catfish juveniles Ciência Rural Copatti,Carlos Eduardo; Garcia,Luciano de Oliveira; Kochhann,Daiani; Cunha,Mauro Alves da; Becker,Alexssandro Geferson; Baldisserotto,Bernardo. 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 quelen) survival and growth after 32 days. 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 CaCO3 L-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 CaCO3 L-1 and at low water hardness (next zero) pH must be reduced.

Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782011000800030 Survival, growth and metabolic parameters of silver catfish, Rhamdia quelen, juveniles exposed to different waterborne nitrite levels Neotropical Ichthyology Lima,Ronaldo L. de; Braun,Neiva; Kochhann,Daiani; Lazzari,Rafael; Radünz Neto,João; Moraes,Bibiana S.; Loro,Vania L.; Baldisserotto,Bernardo. High nitrite (NO2-) levels may develop in aquaculture systems due to high fish density, but studies of lethal concentration values and the effect of NO2- on metabolic parameters and growth are scarce. Consequently, in this study was verified the lethal concentration at 96 h (LC50-96h) for (NO2-) in juvenile silver catfish, Rhamdia quelen and the effect of four waterborne NO2- concentrations (0.06, 0.46, 1.19, and 1.52 mg.L-1) on growth, and hepatic and muscular lactate, glucose, glycogen and protein. Nitrite LC50-96h was 20.46 (confidence interval: 16.10-23.68) mg.L-1. In the growth experiment, exposure to NO2- did not affect weight, length or specific growth rate, but due to mortality (66.7% and 100% after 20 and 40 days, respectively), biomass of...
