Population Monitoring Results
- Estimates of the number of medium to large (over 18.2 kg/18 pounds) sturgeon present in the SRSMB area, calculated annually over the past decade, have averaged around 1,000 fish.
- It is not clear that there is any trend from year to year. Results depend on which years and sizes are included in the analysis.
- Sturgeon abundance may be remaining steady, or may be declining slightly. But certainly, it has not been increasing from year to year.
