Reducing Fuel Use in Tropical Shrimp Fisheries

Welcome to

The Trade Adjustment Assistance (TAA) program for Farmers delivered technical assistance to producers of agricultural commodities and fishermen who have been adversely affected by import competition. The TAA program delivered training to nearly 10,000 producers of Catfish, Asparagus, Maine Wild Blueberries, as well as Shrimp and Lobster fishermen.


You can view any of the free online training courses developed for the TAA program. TAA participants also completed business adjustment plans using AgPlan (, the online business plan writing app; or AgTransitions (, an online transition planning app. Since the end of TAA the AgPlan development team has developed a fishing specific software call FishBizPlan (

Unfortunately, this program has ended because federal funding for the program was cut. If you have questions related to TAA for Farmers, please contact the Center for Farm Financial Management at

This intensive course outlines the process used to identify, evaluate, and modify cambered trawl doors and High-density Polyethylene webbing that can help shrimp fishermen reduce production expenses while catching the same quantity of shrimp as their traditional gear. Expenses that can be reduced by using this fuel-saving trawl gear include fuel, expense for scheduled engine overhauls, net-dipping expense, and acquisition costs for the gear itself (due to its longer life). In addition to examining the performance of this new gear, we provide tuning and adjusting techniques, decision support for replacing traditional doors with the new cambered doors, and the fuel-saving performance industry cooperators found through the cooperative research process. Finally, this educational module assesses the economic results of a cost-reducing investment in the new, longer-lasting trawl gear.
