Run upstream migration routine

run_upstream_passage.Rd

Run the upstream migration routine for adult Atlantic salmon in the Dam Impact Analysis (DIA) model v67 during year 6. Not intended to be called directly.

Usage

run_upstream_passage(
  hatchery_returns,
  hatchery_proportions,
  wild_returns,
  wild_proportions,
  upstream_passage,
  straying_matrix,
  p_mainstem_up,
  stocking,
  n_broodstock,
  inefficiency_matrix
)

Arguments

hatchery_returns

Total number of hatchery smolts exiting river in year 4.

hatchery_proportions

Proportion of individuals attempting to return to each production unit (PU in the river). Within the `run_dia()` function, these values are passed as output from `run_downstream_migration()`.

wild_returns

Number of wild-reared smolts exiting river in year 4.

wild_proportions

Proportion of individuals attempting to return to each production unit (PU in the river). Within the `run_dia()` function, these values are passed as output from `run_downstream_migration()`.

upstream_passage

Numeric vector with length = 15 corresponding to dam passage efficiencies at each of 15 dams in the watershed that are used to delineate PUs. Default usage is to inherit these values from the link{run_dia} function's `upstream_passage` argument using default values based on NMFS (2013) prescriptions as implemented in Nieland and Sheehan (2020).

straying_matrix

A dataframe identical in structure to the built-in straying_locations dataset.

p_mainstem_up

Probability that fish use the mainstem Penobscot River (and not Stillwater Branch) for upstream migration around Marsh Island.

stocking

Number indicating whether hatchery stocking is on (`1`) or off (`0`). Will be a vector corresponding to `n_generations` at some point.

n_broodstock

Target number of adult returns collected at Milford Dam for spawning at US Fish and Wildlife Service Craig Brook National Fish Hatchery each year. Broodstock are collected upstream of Milford Dam in run_upstream_passage.

inefficiency_matrix

A matrix identical in structure to the built-in inefficiency_matrix dataset.
