The age and growth of the pintado Pseudoplatystoma corruscans were studied during the period from May 1994 to May 1995. The standard length ranged from 52 to 145 cm and the weight from 1.3 to 41kg. The biometric relationship between the standard length (Ls) and length (Ltotal) and between the total weight (Wt) and the standard length (Ls) were obtained or the species, being respectively: Ltotal=3.296 + 1.069 * Ls and Wt = 0.00624* Ls 3.134. The condition factor calculated monthly suggests the spawning season to be between the months of February and March. The age was estimated by counting growth rings present in the spines of the pectoral fins, and 10 age classes were detected. The mean distance of the last ring until the border of the spine suggests that the period of least growth is between July and September (dry period). Von Bertalaffy's equation describing the growth of the pintado is: Lt=183* [1 - exp - 0.085* (t + 3.274)]. Total mortality was Z=0.24 year -1 and natural mortality M=0.20 year-1. As the present level of exploitation, F=Z - M=0.04 year-1, we conclude that the pintado stock was still underexploited in the Pantanal in the sampled period. |
