Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...
Modeling the Ecological Impacts of Flaming Gorge Dam Operations
Hydropower operations at Flaming Gorge Dam on the Green River in Utah, U.S.A., can produce rapid downstream changes in flow and stage during a day. These changes can, in turn, affect ecological...
Entrainment of Eggs and Larval Fish into Propeller Jets
Because larval fish have limited mobility and eggs have no mobility, both are susceptible to entrainment into the propeller jets of passing vessels. Entrainment subjects eggs and larvae,...
Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...
The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...
Three Dimensional Particle Tracking Model for the Sacramento-San Joaquin Delta
Flows into and out of the Sacramento-San Joaquin Delta are presently regulated in part by threatened and endangered fish species concerns. To aid in planning future project operations,...
Sound Way to Save Fish
Fish protection need not cost an arm and a fin. Using light and sound to spare fragile blueback herring and other species a harrowing fate, the U.S. Army Corps of Engineers devised a fish...
Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...
Tailwater Fishery Management Using a Fish Bioenergetics Model
Water releases from TVA reservoirs exert great influence on downstream water quality. Analytical tools to quantify biological response to altered environmental conditions, such as dissolved...
Managing Reservoir Storage for Fish Production
Salmon populations in numerous Pacific Coast rivers are in decline and are in danger of becoming threatened or endangered. A reservoir system simulation model was developed for the Trinity...
Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...
Instream Flow Strategies for Operation of the Federal Central Valley Project
Federal Central Valley Project (CVP) operations and policies of reservoir storage and river releases for fish and wildlife protection and restoration are discussed. Prescribed strategies...
Water Policy Change, Implications for Pyramid Lake
Pyramid Lake is part of and is surrounded by the Pyramid Lake Indian Reservation. The river system has been administered by a Federal water master serving the Federal court system with...
The Economic Cost of Stocking Catchable Rainbow Trout
States annually stock about 20 million pounds of catchable trout in public waters. Complete information on cost is essential to help wildlife agencies make operating and planning decisions....
Differential Dynamic Programming for Estuarine Management
Differential dynamic programming (DDP) is applied to solve the estuarine management problem to determine the optimal amount of freshwater inflows into bays and estuaries in order to maximize...
Development of Fisheries Models for the Missouri River System
This paper describes how the value of fisheries resources under various Missouri River operating alternatives was determined. The four fish communities evaluated were the reservoir cool/warm...
A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...
Farakka Barrage - It's Impacts and Possible Mitigation
The paper discusses the impacts and possible implications of the Farraka Barrage Project across the Ganges River on different sectors in Bangladesh including hydrology and river morphology,...
A Fish Bypass Screen at Puntledge Project
An Eicher screen has been designed for the Puntledge Diversion Project on Vancouver Island in British Columbia, Canada. Its purpose is to reduce the mortality of downstream migrating juvenile...
Fish Entrainment and Strategies for Diversion
Hydroelectric power projects often impound reservoirs which contain important recreational fisheries. The entrainment of fish through these facilities and the possible associated entrainment...
