Louisiana’s millions of acres of wetland habitat are home to an abundance of blue crabs.
The blue crab’s scientific name is Callinectes sapidus means beautiful swimmer that is savory - recreational and commercial fishermen alike love blue crab for its delicate, sweet flavor.
The Louisiana Department of Wildlife and Fisheries actively monitors the blue crab population and fishery. At hundreds of sample locations, they tow a trawl through the water, count and identify the species they catch, measure a random selection of the crab catch and record the data. Water temperature, salinity and dissolved oxygen levels are recorded. Water temperature, salinity and dissolved oxygen levels are also recorded. They use this information to estimate the size of the population.
Fisheries managers monitor the commercial harvest of blue crabs using the trip ticket system. Trip tickets are completed by crab docks and processors who buy blue crabs from commercial fishermen. LDWF has limited data on recreational harvests of blue crabs but estimates they are a minor percentage of total harvest. Fisheries managers use all of the available data to manage blue crab populations so they can remain healthy and sustainable. Minimum size limits, escape rings and a professionalism program are just a few of the tools used to ensure a successful blue crab fishery.
