CRiSP.1.6 Theory and Calibration manual (html and pdf)
CRiSP.1 predicts downstream migration and survival of individual stocks of wild and hatchery spawned juvenile fish from the tributaries and dams of the Columbia and Snake rivers to the estuary. The model describes in detail fish movement, survival, and the effects of various river operations on these factors. It is also stochastic, incorporating measures of variability and uncertainty into survival predictions.
CRiSP Harvest Chinook Salmon Harvesting Model
Release of CRiSP Harvest v.3.0.6, Friday, 05-Dec-1997 15:27:10 PST
CRiSP Harvest simulates salmon harvests from a number of years, stocks (hatchery and wild), and fisheries (troll, net, and sport). A key feature of the model is the interaction between stocks through annual catch ceilings imposed upon fisheries that harvest multiple stocks. Other variables include fixed escapement goals, time/area closures, size limits, and brood year survival rates. CRiSP Harvest produces information to help managers evaluate alternative management actions and changes in environmental factors.
Juvenile Salmon Travel Time Model
Juvenile Salmon Travel Time Model predicts the time it takes for juvenile salmon to migrate through segments of the Columbia and Snake Rivers during their migration to the Pacific Ocean. This information is useful for river management actions that attempt to increase the survival of juvenile salmon.
