Production and Economic Comparison of Single Versus Multiple Harvests of Hybrid Catfish in a Commercial In-pond Raceway System in West Alabama Targeting Two Market Outlets

SEAFWA Journal Volume 6, March 2019

This study evaluates the production and economic feasibility of a fixed-floor, in-pond raceway system (IPRS) to supply processor and niche live catfish markets while also highlighting production issues that arose by targeting these two markets. A west Alabama catfish producer grew hybrid catfish (♀ Ictalurus punctatus x ♂ Ictalurus furcatus) to market size in two production cycles (2012–2013 and 2013–2015). Management and harvest of IPRS-raised catfish changed from production cycle 1 to production cycle 2 due to higher market prices received from niche-live fish market buyers. The high...

Evaluation of Split-Pond Systems for Production of Channel Catfish Fingerlings

SEAFWA Journal Volume 8, March 2021

Assessing alternative pond production systems that may reduce avian predation of channel catfish (Ictalurus punctatus) is of extreme interest to state/federal and private hatcheries. This study evaluated the culture of channel catfish fingerlings in a pilot-scale split-pond system (SPS) and compared it to traditional earthen ponds (TP). Six 0.04-ha ponds were covered by netting and stocked with channel catfish fingerlings at a rate of 200,000 fish ha–1; ponds were evenly split between TP and SPS. Fingerlings were cultured for 99 days and fed a commercial diet twice daily. Fish were fed 4.0...
