Marine - Species - Blue Crab
Commercial blue crab pot fishery landings improved in 2011, approaching the long-term average. This halts a decline beginning in 2002, when landings were impacted by decade-long drought conditions and relatively low abundance. Periodic surveys of recreational crabbing indicate that it is important during the warmer months. Data presented in this graph were provided by DNR Fisheries Statistics Section.
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, changes in fishing effort, or both.
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 average includes approximately 68% of the values. Approximately 95% percent of observations in the data set are found within two standard deviations of the average.
