“…Thus, the intensification of catfish production found in this study would be expected to enhance the environmental performance of catfish production. A 2021 study reported a high level of efficiency in the new, more intensive catfish production methods in the use of resources such as land, labor, capital, management, energy, and water (Engle, Hanson, & Kumar, 2021; Engle, Kumar, & van Senten, 2021).…”

“…However, the intensity (level of use of a given technology over any period) and the extent of adoption (number of technologies and adopters) depend on the nature of the industry and the economic, social, political, and regulatory environments (Rogers, 2003). In the catfish industry, the contraction period (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) likely triggered renewed interest in production technologies that are more cost-efficient (Engle, Hanson, & Kumar, 2021).…”

“…The catfish industry, the largest US aquaculture segment, has evolved dynamically in response to marketing and production challenges since its inception in the late 1950s (Engle, Hanson, & Kumar, 2021). Competition from lower‐priced imports and higher input prices, especially that of feed, have had the greatest impacts on farms in recent times.…”

The 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.

“…While the global “blue revolution” has seen an expanded emphasis in non‐Asian countries (Garlock et al. 2020), U.S. catfish farmers continue to face many challenges for economic viability (Engle et al., in press). As biology is a key component in enhancing production and is the basis for understanding catfish ecology, it was the predominant topic published in the 1970s and 1980s (Figure 1).…”

The Third International Catfish Symposium was held in Little Rock, Arkansas, in 2020 and provided another milestone to gauge advances in knowledge related to conservation and management of these valuable fishes. Attendees from 29 states and 4 countries gathered to communicate research and information on the conservation, ecology, and management of the world’s catfishes. During 3 d of technical sessions and workshops, 74 oral presentations and 17 posters were shared with 198 attending fisheries professionals. Plenary and oral presentations were recorded and are available online (https://www.youtube.com/channel/UCHNt7ZV05DLWoe4qJO798Pw/videos), aligning with the symposium theme of “Communicating Catfish Science.” Technical sessions explored current research and management issues that included population demographics, introduced catfish populations, sampling methods, harvest management, human dimensions, conservation, habitat use and movement, biology, and aging methods. Ultimately, 38 manuscripts were peer reviewed and published as this special issue of the North American Journal of Fisheries Management. Interest in catfish science, as gauged by publications in six peer‐reviewed fisheries journals, has grown steadily since a 1910 catfish aquaculture article appeared in the Transactions of the American Fisheries Society. Biology and ecology topics became prominent in the 1970s and 1980s, while articles on techniques and fisheries management have grown steadily through 2020. Ecology, fisheries management, and techniques were the most published topics in the three international catfish symposia. Future research and management efforts will continue similar work but also seek to address the expanding role of catfish as invasive species and a better understanding of the ecology and conservation of small‐bodied native catfish. Among the greatest challenges will be adapting current tools and identifying future knowledge gaps as we experience a changing climate. This will require an enhanced understanding of transforming ecosystems and advanced adaptive management applications. The decadal occurrence of a dedicated symposium has served to summarize progress and focus future efforts to advance catfish science.

“…Catfish is the largest segment of U.S. aquaculture [4], but imports of tilapia and pangasius have reduced the share of U.S. catfish consumed from 80% in 2002 to 24% in 2019 [5,6]. In 2008, the National Fisheries Institute reported [7] that U.S. per capita consumption of tilapia and pangasius was 1.2 and 0 lb, respectively, while consumption of U.S. Catfish was 0.92 lb.…”

To increase the demand for U.S. farm-raised catfish, five healthy, convenient ready-to-cook products were developed to expand consumers’ options beyond basic fresh or frozen fillets. Five new catfish products were produced, consisting of one hundred samples of each, including three size-types of Panko-breaded fish products (strips, center cuts of regular fillets, and center cuts from Delacata fillets) and two marinated products (sriracha and sesame-ginger). The breaded products were to be prepared by baking for convenience over traditional frying methods, while the marinated products were to be microwaved as healthy and convenient products. The nutrient content of the samples was analyzed, including protein, moisture, fat, fiber, ash, and carbohydrate, as well as minerals, amino acid, and fatty acid constituent content, with associated atherogenic index (AI) and thrombogenic index (TI), showing unique differences between the Panko-breaded and marinated products. In addition, a trend was observed showing an increase in moisture, protein, ash, and carbohydrate percentages, and a decrease in lipid content related to the volume-to-surface-area ratio, having the order of strips < standard fillets < Delacata fillets.
