Soft shell blue crab (Callinectes sapidus) aquaculture is one of the oldest domestic aquaculture industries along the East and Gulf Coasts of the United States. Historically, soft shell aquaculture in the United States produced over 1 million pounds valued at $5.5 million. However, the industry has been in decline over the last 30 years. Hurricanes, flooding events, and changes in salinity and water quality have attributed to the decline in the industry. In an effort to increase soft shell crab production, we have developed several extension tools (factsheets and videos) and conducted several workshops to increase participation in the industry, and make the industry more resilient to change. Topics covered include: components of recirculated systems, biological filtration basics in recirculating crab systems, crab mortality during summer months, system maintenance, water sources, start-up tips, seasonal costs for recirculated shedding systems, harvesting good peelers or busters, nitrifying bacterial products to acclimate systems, start up and seasonal costs, and virus transmission in shedding systems.
