This newsletter discusses armyworm control in late summer planted crawfish forage, results of research on the potential effects of summer drought and excessive summer rainfall on crawifsh survival and reproduction prior to fall flood-up, irrigation of crawfish forage crops with slightly salty water, and LSU AgCenter crawfish news.

This report is a survey of Louisiana wild commercial crawfish license holders conducted in 2010 to determine their preferences and perspectivesof actual and hypothetical regulations and management practices of the wild commercial crawfish fishery in Louisiana.

The crawfish aquaculture industry, located primarily in Louisiana, has remained viable and resilient despite some considerable constraints. Success can be attributed to several factors.

This report evaluates the economic impact of crawfish as a rotational crop on the rice enterprise, indentifying specific costs imposed on the rice enterprise unique to crawfish production and presenting relevant economic principles in the assignment of production costs to alternative farm enterprises from a farm accounting perspective.

This chapter (Chapter 9) from the Louisiana Crawfish Production Manual discusses other management considerations in commercial crawfish farming, including pond flood-up, population management, supplemental feeding, managing ponds for larger crawfish, diseases, predators, nuisance wildlife, control methods and deveoping your business.

Crawfish aquaculture relies on control of pond hydrology to simulate optimal wet and dry conditions occurring in natural riverine and wetland habitats. Crawfish grow and mature during the wet or flooded cycle and survive the dry periods by digging burrows.

The species of crawfish important in the southeastern United States are the red swamp crawfish (Procambarus clarkii) and the white river crawfish (Procambarus zonangulus). Culture methods are relatively simple compared to those for other aquatic animals. Crawfish culture can fit well with farm management plans because it uses marginal lands, existing labor and farm equipment during off-peak farming periods.

Freshwater crawfish of the genus Procambarus are a valuable aquaculture commodity in the southern United States, with annual production of 30 to 50 million pounds and farm-gatevalues of $25 to 50 million. Unlike fishes, crawfish are not harvested by seining. Instead, crawfish are harvested with a passive system that uses baited traps.
