Investigation of Techniques for Differentiating Stocked Hatchery Reared and Native Fingerling Striped Bass
Project number: AFS-9
To determine a distinguishing characteristic and/or suitable tagging or marking technique for differentiating stocked hatchery reared striped bass fingerlings from native river populations of striped bass fingerlings.
Fish culture techniques were developed at Richmond Hill Fish Hatchery for rearing fingerling striped bass, Morone saxatilis (Walbaum), from small size (1.5 to 2 inches) to advanced size (4 to 6 inches). Average survival of 121,585 small fingerlings reared to advanced size was 54.0 percent during the study period. Survival was highest (73%) during the fourth year as rearing techniques improved.
