Plant Natural Compounds with Antibacterial Activity towards Common Pathogens of Pond-Cultured Channel Catfish (Ictalurus punctatus)
نویسنده
چکیده
The bacteria Edwardsiella ictaluri and Flavobacterium columnare cause enteric septicemia and columnaris disease, respectively, in channel catfish (Ictalurus punctatus). Natural therapeutants may provide an alternative to current management approaches used by producers. In this study, a rapid bioassay identified plant compounds as potential therapeutants. Chelerythrine chloride and ellagic acid were the most toxic toward E. ictaluri, with 24-h IC50 of 7.3 mg/L and 15.1 mg/L, respectively, and MIC of 2.1 mg/L and 6.5 mg/L, respectively. Chelerythrine chloride, ellagic acid, β-glycyrrhetinic acid, sorgoleone, and wogonin were the most toxic towards two genomovars of F. columnare, and wogonin had the strongest antibacterial activity (MIC = 0.3 mg/L).

Discovery of Golden-Colored Channel Catfish (Ictalurus punctatus), with Preliminary Culture Evaluations
Channel catfish (Ictalurus punctatus) with a golden pigment and black spots were discovered during harvest of a University of Arkansas at Pine Bluff (UAPB) experimental channel catfish production pond. Golden catfish were mixed with catfish of normal pigmentation and of similar sizes. Following the observation that differences existed in algal-off flavor, three golden and three normal pigmented...

Musty "off-flavor" in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least 30 million US dollars annually. The cyanobacterium Oscillatoria perornata (Skuja) is credited with being the major cause of musty off-flavor in farm-raised catfish in Mississippi. The herbicides diuron and copper sulfate, currently used by catfish produce...
متن کاملEffects of Feeding Diets with and without Fish Meal on the Production of Channel Catfish, Ictalurus punctatus, Stocked at Varying Densities
Animal protein, generally fish meal, has traditionally been used in the diet of channel catfish. However, our previous research indicates that animal protein is not needed for growing stockersize catfish to food fish when the fish are stocked at densities typical of those used in commercial catfish culture. Whether this holds when fish are stocked at high densities is not known; thus, we conduc...
