Some authors use a constant coefficient for all sub-samples (seasons of the year, for instance), whilst others calculate b value for each sub-sample. To demonstrate which of these methods fits better, this study verified that the use of one b value for each sub-sample leads to distortion of Condition Factor values. Comparing the two tested methods, it may be concluded that the method which calculates b coefficient from groupings of all individuals and uses b as a constant value for all sub-samples is the most convenient method to study fish condition.397-400engCondition factorCondition indexHypostomus strigaticepsLength-weight relationshipMethodsallometrybody heightcontrolled studycorrelation coefficientfishintermethod comparisonmeasurementmorphometricsnonhumansampletechniqueweightzoologyHypostomusArtigo10.4025/actascibiolsci.v24i0.2311Acesso aberto2-s2.0-00369422942-s2.0-0036942294.pdf9317499005247273
