This study was conducted to determine if channel catfish could be cultured at an increased density in the Partitioned Aquaculture System (PAS) without significantly affecting performance. Channel catfish fingerlings (36.53±6.76 g; mean ±SD) were in

Uptake and clearance of Edwardsiella ictaluri in the peripheral blood of channel catfish Ictalurus punctatus fingerlings were monitored for 216 h after exposure to E. ictaluri for 4 h and 8 h under static conditions. Most fish exposed to E. ictaluri

Fingerling channel catfish Ictaturus punctarus were stocked into eight 0.04-ha ponds at 12,500 fishlha (treatment 1) and 50,000 fish/ha (treatment 2) with four ponds per treatment. At the end of of phase I (59 d) 50% of the fish were removed from eac

A production strategy for channel catfish Ictalurus punctatus that helps increase pond production, keeps size-classes of fish in discrete groups, and provides multiple harvest dates throughout the year was developed and tested. Fingerling catfish wer

Ecteinascidia turbinate extract (Ete) dramatically decreased the survival of channel catfish Ictalurus punctatus that were challenged with a virulent strain of Edwardsiella ictaluri. A 0.625-μg or a 1.250-μg dose of Ete administered intraperitoneal

During the summers of 1990 and 1991 in the Lowcountry region of South Carolina, high mortality rates (50-90%) of channel catfish, Ictalurus punctatus, in production ponds were attributed to the toxic form of the blue-green alga (Cyanobacterium) Aphan

Sarafin (sarafloxacin hydrochloride), a new antibacterial, was evaluated in the field on a naturally induced infection of Edwardsiella ictaluri in channel catfish, -Ictalurus punctatus. Healthy channel catfish (mean weight = 50 g) were stocked into n

Little is known about the pathogenic mechanisms possessed by Edwardsiella ictaluri, the etiological agent of enteric septicemia of catfish (ESC). Extracellular products probably play a major role in the pathogenesis of the disease. Comparative studie
