In CRiSP.1, passage and survival of fish through a reservoir is expressed in terms of the fish travel time through the reservoir, the predation rate in the reservoir and a mortality rate resulting from fish exposure to nitrogen supersaturation, an effect called Gas Bubble Disease. CRiSP.1 formulates these mortality factors individually (Fig. 23).
The processes that determine the factors are complex, and not fully understood, while information to characterize them is limited. In light of the observational and theoretical uncertainties, the modeling approach has been to develop alternative submodels of reservoir mortality. In this manner CRiSP.1 users can run a scenario with alternative models and compare the different effects on fish survival.
