Abstract:

A preliminary age and growth study of largemouth bass, Micropterus salmoides (Lacepede) in the northern sector of Walter F. George Reservoir was conducted from January 19, 1972 through June 23, 1972. Four hundred sixty-seven bass were collected from the study area by electrofishing. Age and growth determinations were difficult due to indistinct annuli. The length-weight relationship for bass in this sector is expressed by the formula W = 0.00009856 x L3.4617. There was no significant difference in the mean lengths and weights between sectors, between collection areas or between males and females. The relative condition of fish in this study was computed by the formula Kn = W/^W. The sex of 389 fish was determined. Bass appeared to mature at approximately 300 mm in length. Anglers reported 26 recaptures from a total of 432 fish which had been tagged and released. The peak of the spawning activity occurred after the first week in April. Approximately one bass was collected per minute of actual shocking time. Genetic influence from the Florida subspecies, warm temperatures and an abundance of food favored rapid growth in this reservoir.
