Length–weight relationship (LWR) and relative condition factor (Kn) of wild Paracheirodon axelrodi after caught and simulated transport were investigated. These fish were random distributed in two groups: wild fish (pre-transport) and after caught (post- transport). For each group the body weight and total length were measured to determination from LWR and Kn. The LWR of fish in pre-transport was Wt = 0.014Lt2.528 (r2 = 0.966) and in post-transport was Wt = 0.010 Lt2.848 (r2 = 0.956). Both groups had a negative allometric growth and differences between values of b (p0.001) were observed. Body weight of fish and Kn were lower during post-transport.  Results demonstrated that post-transport is crucial phase in the extractives fishery from P. axelrodi, due to poor body conditions of the fish, which was indicated by the LWR and Kn. Therefore, they indicates the necessity of improve in the management techniques during and after the caught of this ornamental fish from Amazonian.Keywords: Allometric growth, cardinal, ornamental fish, stress, transport.
