Eat but don't get eaten: after restoration, young salmon better off: Habitat restoration has had major benefits for juvenile salmon in the Columbia River Estuary, including new rearing habitat where food is plentiful and where the risk of being eaten is low, accordingly to a USGS study. Models showed that temperature was an important reason for the increased young salmon growth in areas of the river that the current didn't reach, but this growth spurt was somewhat counteracted by the fact that typical foods eaten in the main part of the river were higher in energy. USGS scientists successfully used bioenergetics, a field of biology that looks at the flow of energy in living systems, to study the effectiveness of the restoration project. The study also points to the importance of refuges to keep young salmon safer from predators, a distinct benefit afforded by restoration. This study, Eat, but don't get eaten -- quantifying the energetic benefit of Columbia River Estuary restoration to juvenile salmon, will be presented Sept. 5 at 2 p.m. in room 609.

Targeting young silver carp for control may pay off: Efforts to reduce the harmful effects of invasive silver carp on native fish should focus on younger silver carp, according to a recent USGS, Kansas State University and University of Missouri study. The USGS and university scientists projected a growth rate of 58 percent a year of silver carp, with their m
