Fig. 2 in Life-history characteristics of Pseudoplatystoma metaense (Teleostei: Siluriformes: Pimelodidae) from the northwestern Orinoco River Basin

Fig. 2. Results of Periodic Regression Model fit to MIA values (dots) for asteriscus otoliths of Pseudoplatystoma metaense (solid line) compared with Apure River flood cycle (dashed line), for the periods June 2000-May 2001 and June 2002-April 2003. Arrows indicate approximate times of opaque zone (annulus) formation in the otoliths.
