Hybrid catfish (Ictalurus punctatus ♀ × I. furcatus ♂) make up a significant portion of U.S. catfish production due to their aggressive feeding nature and rapid growth rate. One of the challenges Alabama producers have faced in recent years is the overabundance of large, unmarketable fish at harvest. Oversized fish (>1.81 kg) present costly challenges by consuming feed and returning reduced processor value. To evaluate oversized fish abundance, 12 commercial ponds in west Alabama were sampled by electrofishing in the period between final harvest and restocking. The fish collected were processed for length, weight, and otolith-based age. Additionally, pond variables such as pond type, average depth, shoreline development index (SLD), depth range, and seine frequency were recorded. Beta regression modeling identified SLD as the strongest predictor of oversized fish, explaining ~73% of the variance (pseudo-R² = 0.73) with significantly higher oversized proportions in ponds with irregular shorelines (p < 0.001). Growth analysis using a von Bertalanffy Growth Function estimated that fish surpassed the oversized threshold by 2.64 years of age, meaning carryover fish quickly advance beyond market size if not fully removed. These findings highlight the importance of pond perimeter design and harvest efficiency in limiting oversized fish prevalence.
