Evaluation of the Supplemental Stocking of Largemouth Bass Fingerlings into Lake Nottely, Georgia

A five-year supplemental fingerling-stocking program was initiated in 2003 to counter decreases in largemouth bass (Micropterus salmoides) abundance and angler catch rates in Lake Nottely. Normal (25 mm TL) and advanced production (50 mm TL) fingerlings were stocked annually (April to June) from 2003 to 2007; all fingerlings were mass marked in oxytetracycline hydrochloride (OTC) to differentiate between stocked and wild largemouth bass. Age-1 stocked fingerling contribution ranged from 17%-100%, age-2 contribution ranged from 0%- 44%, and age-3 contribution ranged from 8%-54%. Mean total length was similar between normal production and advanced production fingerlings at age 1 and age 3 (P ≥ 0.3137). Normal production largemouth bass fingerlings contributed to each age cohort and cost less than advanced production fingerlings.
