SacPAS Fish Model v.2.8:   Sacramento River Chinook egg to fry development and in-river migration  

⇨  See the framework of web-accessible salmon models.
⇨ 
Skip egg to fry modeling and input fish directly into the migration model.

Temperature data inputs (Temps)
NOAA CV-Temp

Interpolated between sites successively downstream:
(KWK, CCR, BSF, BND, and RDB).


Use SHINY Tool to create temps.

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).

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.
