Larval Fish Populations In Little Bear Creek Reservoir During The First Three Years Of Impoundment

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...

Larval Fish Populations During The First Three Years Of Impoundment In Normandy Reservoir, Tennessee

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...
