SacPAS Fish Model v.2.7.4:   Egg to Fry (Spawning to Emergence) and In-river Migration  

Beta version for testing and evaluation This model is in a development phase. Currently it works best with a modern browser.

WARNING: Certain functionality may not be available in older browsers.

The SacPAS fish modeling process begins with egg deposition at the time of spawning. Development rate and survival can be modeled by various methods to determine fry emergence from the gravel. On this page you can control temperature inputs, redd counts/timing/location and survival details for egg development modeling.

Survival: Redds to RBDD
Temperature effect only for method
Stage-dependent mortality
End crit. window ATUs (°C days)
Compute hatching
TCrit: °C = °F
δ (days): in critical window
bδ (rate): b(rate) applies to "Stage-dependent mortality" when mortality occurs in a critical window of time.

This is daily mortality rate when the critical temperature is exceeded, but only applies during the critical window period.

°C-1d-1 = °F-1d-1
Density effects per kilometer:
B (Base rate): (background max. survival)
D (Carry cap): per KM (averaged by reach).
Stage-independent mortality
TCrit: °C = °F
b (rate): b(rate) applies to "Stage-independent mortality". This mortality rate is applied on any day during the entire incubation period when the temperature goes above the critical temperature.
°C-1d-1 = °F-1d-1
Density effects: (Beverton-Holt)
Base rate: (background max. survival)
Carrying capacity: redds total.
