Xyrauchen texanus (Razorback sucker) is an endemic species found in the Colorado River basin of North America. This study describes the capture of 42 adult, 19 juvenile, and 39 larval fish between 1962 and 1988 downstream from Lake Mohave in the Colorado River System. During this study, there were forty-six additional young captured between 1984 and 1987 in artificial canals that may have been wild or stocked. Wild juveniles have not been found downstream from the Grand Canyon since the 1950s. A majority of the adults and larvae captured were from the river or its mainstream impoundments except for one wild juvenile. Presumably all stocked fish were captured from irrigation canals.
