Razorback Sucker-We recaptured substantially more razorback suckers (n=86) than bonytail
(n=31). The database contained growth information for 86 suckers that had been recaptured
within 9 to 24 months after being marked and released. Growth rates (>6 mm/month) were the
largest for smaller fish and declined with size and age (Figure 10). Average growth rate
substantially declined for fish >350 mm, dropping to 2.5 mm/month and below. Growth
continued for even the largest (<500 mm) suckers, but at the low rate of 0.5 mm/month.
