Surveys show healthy bass in Imperial Division Backwaters
Our Region 4 IV Fisheries Program conducted an annual electrofishing survey of the backwaters of the Imperial Division of the Colorado Riveron Nov. 14-16. These annual surveys are performed to gather data on relative abundance, size, growth of fish, and to detect any large scale changes in the fish population. A total of 2,323 fish were sampled at 16 survey stations including 242 largemouth bass. Other species collected included bluegill sunfish, redear sunfish, black crappie, warmouth sunfish, threadfin shad, gizzard shad, blue tilapia, common carp, striped bass, flathead catfish, and channel catfish. All of the fish were collected, weighed, measured, and released unharmed.
The largemouth bass population in the Imperial Division backwaters appears to be stable and doing well! The largest bass sampled during the survey was 23.4 inches and 8.2 pounds.
Over 24 percent of the largemouth bass captured during the survey were 15 inches or larger, so there should be plenty of large fish to catch! We also sampled a large number of young of year largemouth bass for the second year in a row, which may point to a bright future for the bass population of the backwaters of the Imperial Division of the Colorado River. Overall, based on the result of this survey, the Imperial Division of the Colorado River should continue to provide good fishing anglers have experienced the last several years.
