Marine - Species - White Shrimp
Both the commercial trawl fishery and the recreational baiting fishery have been relatively stable over the last few years, although 2011 catches were lower because of shrimp mortality due to winter cold. Overall levels of catch and effort are much less than high levels observed in the 1990s, driven in part by continued low shrimp prices. 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.
