Additional Graph Information

Commercial and recreational catches are measured in number of individuals or pounds of fish caught. Changes in catch among years may be the result of changes in abundance, fishing effort, or a combination of the two.

On each graph, the horizontal dotted lines above or below the "10 year average" represent one "standard deviation" unit, which is a measure of how variable the annual data are around the 10-year average. In general, the area between one standard deviation above the mean and one standard deviation below the mean includes approximately 68% of all values. Approximately 95% of observations in the data set are found within two standard deviation units of the average and is referred to as the prediction interval.
