Fish from two genetically identified populations of largemouth bass Micropterus salmoides , representing the northern subspecies M. s. salmoides (N × N) and the Florida subspecies M. s. floridanus (F × F), and their reciprocal F 1 hybrids (F × N and N × F; female represented first) were stocked in 0.04–0.48‐hectare ponds and evaluated for growth, condition, and percent survival during the second year of life. Angling and seine‐capture vulnerability were also examined. The F × N cross was significantly heavier and had a significantly higher relative weight (100 [individual weight/standard weight at length]) than the other crosses at the end of the study. The F × F cross was significantly shorter, weighed less, and was in poorer condition than all other crosses. The N × N cross was generally more susceptible to angling than the F × F cross. The F × F cross was significantly less vulnerable to seine capture than the other three crosses.
