Abstract
Two studies investigated various aspects of channel and hybrid catfish production and processing. The first study examined the effects of ammonia stress (15 mg/L vs. 1 mg/L control) on growth performance and fillet quality. While channel catfish demonstrated superior growth, ammonia stress minimally impacted the sensory profiles of both species. Gut microbiota analysis revealed species-specific differences, with Lactococcus lactis dominating hybrid catfish communities. The second study evaluated buffered vinegar treatment (1.5%) on fillet shelf life during refrigerated storage. Vinegar-treated fillets maintained better microbiological quality, with aerobic plate counts remaining below 7 log cfu/g through day 6, while untreated fillets exceeded this threshold. Notably, hybrid catfish fillets treated with vinegar showed the best sensory qualities by day 9. Together, these findings provide insights for optimizing catfish production and processing methods to enhance product quality and shelf life.
