Abstract

Evaluates the survival, growth, and reproduction of the zebra mussel, Dreissena polymorpha, and the quagga mussel, D. bugensis, in riverine mesocosms using untreated, flowing river water. Also examines the seasonal effects of elevated temperatures and the influence of current velocity. Helps predict the ecological success of Dreissena polymorpha in large river ecosystems, and thus their potential impact on water utilities. Also monitors the population dynamics of zebra mussels within the Ohio River. Published in 1997. (Still available to Foundation subscribers as Order 90724.)
