Effects of trichlorfon on ecotoxicological biomarkers in farmed Colossoma macropomum (tambaqui)

open access: yesBrazilian Journal of Biology
Abstract Producers of fish have been looking for viable alternatives for the management of Colossoma macropomum (tambaqui) in confinement systems in order to avoid the harm and subsequent losses caused by parasitic diseases. One alternative used by farmers is pesticides, such as trichlorfon, which has a genotoxic effect.

Modelling growth of Colossoma macropomum (Cuvier): comparison of an empirical and an explanatory model

open access: yesAquaculture Research, 1998
Accumulated data from growth experiments on the nutrition of Colossoma macropomum (Cuvier) were analysed using an empirical (linear regression) and an explanatory model called the fish growth simulator (FGS). Both methods gave satisfactory results. Differences between predicted and observed values fluctuated less with the FGS.
