Egg Growth of Pre-emergent Salmon -- The on-line egg growth model tracks egg development from spawning to emergence, and then uses a bioenergetics to model the growth of fry after emergence during their first season of growth. It is useful for examining the role of seasonal temperatures on early life development and growth.
Vitality Model -- The vitality-based survival model is a parametric model for relating stressors and environmental properties to organism survivorship. The web page includes research papers, S-PLUS code, sample data file, and documentation.
Fish Passage
CRiSP Passage (Columbia River Salmon Passage Model) -- CRiSP Passage model predicts downstream migration and survival of individual juvenile salmonid stocks from the tributaries and dams of the Columbia and Snake rivers to the estuary. It is also stochastic, incorporating measures of variability and uncertainty into survival predictions. The web page includes the CRiSP Passage executable, data files, and documentation.
Eulerian-Lagrangian-Agent Method (ELAM) Integrating spatial/cognitive ecology, particl-tracking, and
hydraulic/water quality modeling for fisheries engineering &
ecohydraulics research -- ELAM is a mechanistic mathematical
approach for decoding and forecasting the multi-dimensional movement
behavior patterns of individual animals responding to patterns in
abiotic and biotic stimuli available to engineering (e.g., hydrodynamic,
water quality, eutrophication, GIS, etc.) models or a priori field data. External Link
Juvenile Salmon Travel Time Model -- This research is conducted as part of the Columbia River Salmon Passage (CRiSP) model. Our goal is to predict the time it takes for juvenile salmon to migrate through segments of the Columbia and Snake Rivers during their migration to the Pacific Ocean.
RealTime Forecasters -- The Realtime Forecasters use pattern recognition techniques to predict the percent of the run-to-date and days to a specific percent of the run of juvenile salmonids in the Columbia Basin. The statistical algorithms smooth historical trends in PIT tag arrivals or passage indices and use a generalized weight least squares decision criterion in making predictions.
Harvest
Coast Model -- The Coast Model is a code framework that can be configured at runtime to represent many different models depending upon the specific process algorithms and data specified in the input files. Currently, the Coast Model only contains algorithms used by the Pacific Salmon Commission (PSC) chinook model. The web page includes the Coast Model executable, data files, documentation, and source code.
CRiSP Harvest (Chinook Salmon Harvesting Model) -- CRiSP Harvest model simulates the harvest of 30 chinook salmon stocks by 25 fisheries over an extended time horizon. The geographic range covered by the model extends from Southeast Alaska to the Oregon coast. The web page includes the CRiSP Harvest executable and documentation.
Parameter Estimation
PitPro (PIT Tag Processor) -- Includes
CaptHist. A program for processing PTAGIS data into capture histories. PitPro
has a graphical user interface while CaptHist is a console or command line
application.
ROSTER (River-Ocean Survival and Transportation
Effects Routine) Program ROSTER models the life cycle of Pacific salmonids
from the initiation of the juvenile migration as smolts to the end of the
spawning migration as adults.
SampleSize -- A suite for four sample size programs for estimating parameters: SingleRelease, PairedRelease, PairedRadio, and TransportInRiverRatio. The web page includes the SampleSize executables.
SURPH (SURvival under Proportional Hazards) -- SURPH is an analytical tool for estimating survival using release-recapture data as a function of environmental and experimental effects. The web page includes the SURPH executable and documentation.
USER (User Specified Estimation Routine) -- The program USER is a flexible software tool that allows investigators to develop statistical models for analyzing tagging and counts data. The web page includes the USER executable and documentation.
Utilities -- Various utilities
for use in conjuntion with the above programs.
Past Projects & Programs
Dissolved Gas Modeling Core Team -- From 1995 through 1997, the Dissolved Gas Modeling Core Team web page coordinated the work of multiple agencies to develop and implement dissolved gas modeling for the major hydroelectric projects in the Columbia Basin.
NMFS Harvest Modeling Project -- From 1996 through 1999, the NMFS Harvest Modeling Project web page coordinated the work of multiple agencies to develop and implement various harvest algorithms including the CRiSP Harvest model, PM Selective Fishery Modeling and Data Retrieval, and the PSC Selective Fishery Simulation Model.
Radio Telemetry Survey -- This experimental tool was developed in 1997 to plot juvenile salmon radio telemetry data.
GeoMap for Java - Java Mapping System for GIS Data. GeoMap is a collection of Java classes designed to display latitude and longitude coordinate data on an interactive canvas. The tool was written in 1997 and no further development is planned. The web page includes the source code.
