Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, EarlyView.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...
