dc.description.abstractThe US catfish industry has undergone significant technological advancements in an attempt to achieve cost efficiencies. This study monitored the progress of the adoption of alternative and complementary technologies in the US catfish industry. A 2019-2020 multi-state in-person survey in Alabama, Arkansas, and Mississippi (n = 68), revealed increased adoption of intensively aerated ponds (6,315 ha) and split ponds (1,176 ha). The adoption of alternative, more intensive, production practices has been accompanied by increased adoption of complementary technologies of fixed-paddlewheel aeration, automated oxygen monitors, and hybrid catfish. As a result, the average aeration rate in the tristate region has increased to 7.8 kW/ha with 97% of catfish farms adopting automated oxygen monitors. About 53% of the water surface area in the tristate region was used for hybrid catfish production. Fingerling producers have also adopted a feed-based, oral vaccine against Enteric Septicemia of Catfish, with 83% of the fingerling farms and 73% of the fingerling production area vaccinated against ESC in 2020. Increased adoption of productivity-enhancing technologies in the US catfish industry explains the 59% increase in foodfish productivity from 2010 to 2019. Monitoring the progress of adoption of productivity-enhancing technologies will guide researchers and Extension personnel involved in the refinement and dissemination of these technologies.en
dc.description.notesWe sincerely thank all the catfish producers and processors from the states of Alabama, Arkansas, and Mississippi who provided us with their responses. We also thank the United States Department of Agriculture-National Institute of Food and Agriculture-Southern Regional Aquaculture Center (USDA-NIFA-SRAC Grant No. 2018-38500-28888) for funding this research along with support from the Mississippi Agriculture and Forestry Experiment Station Special Research Initiative (MAFES-SRI-Grant #38700) and the US Department of Agriculture National Institute of Food and Agriculture (USDA-NIFA Hatch Project Accession Number 1013160).en
