Evidence Supporting this KER
High degree of plausibility in fathead minnow, zebrafish and other cyprinid species.
Uncertainties and Inconsistencies
There are generally few inconsistencies for experimental studies using model fish species dervied from pathogen-free laboratory cultures. However, there can some uncertainties where wild fish have been used for experimental purposes.
