Reservoir Rehabilitations: Seeking the Fountain of Youth

Aging of reservoirs alters the functions, and associated services, of these systems through time. The goal of habitat rehabilitation is often to alter the trajectory of the aging process such that the duration of the desired state is prolonged. There are two important characteristics in alteration of the trajectory—the amplitude relative to current state and... Read More

Functional Age as an Indicator of Reservoir Senescence

It has been conjectured that reservoirs differ in the rate at which they manifest senescence, but no attempt has been made to find an indicator of senescence that performs better than chronological age. We assembled an indicator of functional age by creating a multimetric scale consisting of 10 metrics descriptive of reservoir environments that were... Read More

Development of Fish Passage in China

China began to develop fish passage at hydroelectric dams in the 1960s, but few were implemented until the 2000s, when a federal law was passed in 2002 that required fish passage at new hydroelectric dams that block fish migrations. Because of this regulation, in the past 10 years, about 40 fish passage facilities have been... Read More

Myths That Continue to Impede Progress in Ecosystem-Based Fisheries Management

Ecosystem-based fisheries management has been perceived as something desirable but pragmatically unachievable due to several impediments identified earlier during its implementation phase. Over the years, many of these impediments have been resolved but not well communicated to stakeholders, managers, scientists, and policymakers. As a result, several past impediments to implementing ecosystem-based fisheries management have taken... Read More

Imprinting of Hatchery-Reared Salmon to Targeted Spawning Locations

A New Embryonic Imprinting Paradigm for Hatchery Programs Straying by hatchery-reared salmon is a major concern for conservation and recovery of many salmon populations. Fisheries managers have attempted to minimize negative ecological and genetic interactions between hatchery and wild fish by using parr-smolt acclimation facilities to ensure successful olfactory imprinting and homing fidelity. However, the... Read More
