We used information from an angler recognition program to assess the relationship between lake-record weights of freshwater fishes captured by Texas anglers and two predictors of fish production and growth: reservoir surface area and growing-season length. The lake-record weights of two species, largemouth bass Micropterus salmoides and flathead catfish Pylodictis olivaris, were directly related to the logarithm of surface area. The record weights of all species studied were unrelated to growing-season length. Regardless of the statistical significance of individual correlations, there was a significant excess of positive correlations across all species between lake-record weights of fish and log surface area. This indicates the presence of a general relationship between the record weights of fish and reservoir area. Our results suggest that record weights of fish may be constrained by reservoir surface area.
