The U.S. Department of Energy's Benneville Power Administration proposes to address two fundamental aspects of lamprey biology by describing diagnostic characters of egg and larval stages of Pacific, river, and western brook lampreys, preparing a meristic and morphometric identification key, and developing molecular techniques suitable for differentiating Columbia River Basin lampreys, and then examining the effects of temperature on the timing of developmental events and on the survival of early life history stages of lampreys. This work helps to answer questions about lampreys, providing tools for population assessment and the quantification of habitat needs will help managers in developing strategies to ensure the long-term stability of lamprey populations. Accurate identification techniques will allow managers to conduct larval lamprey surveys and thus determine the relative abundance of each species in various habitats. Less...
