The data from 3 years of ichthyoplankton sampling during the initial impoundment of Little Bear Creek Reservoir are presented. Trends of percentage composition and abundance are discussed by family and taxon. The Centrarchidae greatly outnumbered other families of fishes throughout the study, while c1upeids failed to become established. Strong year classes of Lepomis and Pomoxis were produced during the first year of impoundment. Relative failures of the second and third years are attributed to lack of spawning success in the case of Lepomis and predation in the case of Pomoxis. The...

Seasonal abundance of larval fishes in Normandy Reservoir, Tennessee, was determined during the first 3 years (1976-1978) following impoundment. Relative abundance of major taxa collected with a 0.5 m frame net was compared with results of cove rotenone samples to measure year-class strength. Centrarchids dominated both larval and cove rotenone populations throughout the investigation. The strongest year class of crappie (Pomoxis spp.) was observed in 1976, even though greater larval abundance (5 times) was recorded in 1978. Threadfin shad (Dorosoma petenense) were stocked and subsequently...

Meristic variation was examined among samples of northern largemouth bass, Micropterus salmoides salmoides, from Arkansas and compared with variation found in samples of the Florida largemouth, Mifloridanus. Meristic characters employed in this investigation included five scale counts and number of pyloric caeca. Statistical analyses of the data involved analysis of variance, discriminant function analysis, and Hotelling's T2 test statistic. The primary objective of this study was to establish the best criteria for the practical separation of the two subspecies and, if possible, their...
