Description:

"In this study we examined the reliability of California's commercial groundfish landing estimates from 1969-2006. To determine the reliability of the estimates, we examined potential problems including: species misidentification, landing receipt errors, and unusual patterns in landings. We found that landing estimates for most species were at least generally reliable; however, there were some problems which could not be adequately resolved. In many cases where there were potential problems, we were confident that total landings were probably small. In other cases, we found that recent landing estimates were reliable; however, early landing estimates were questionable. We also found that for northern California, we will need to modify our landing estimation method for the years 1969 through 1977. In some cases, end users could improve landing estimates with more detailed analyses"--Abstract.
