In the Hudson River estuary, what quality length (cm) and corresponding age did the slower-growing White Catfish typically achieve?

Answer

33 cm by age 6

When comparing growth rates between the native White Catfish (*A. catus*) and the introduced Channel Catfish (*I. punctatus*) within the Hudson River system, a distinct competitive disparity is observed. The White Catfish exhibits relatively slow growth in this system, taking an extended period to reach a benchmark size. Specifically, *A. catus* required six years to reach a 'quality length' measurement of 33 centimeters. In contrast, the faster-growing Channel Catfish achieved a larger quality length (41 cm) in only five years, highlighting a significant competitive advantage for the introduced species regarding resource utilization and development speed.
