Make population
make_pop.Rd
Function used to seed initial age-structured population for simulation based on life-history characteristics. Uses an initial population seed, mortality estimates, and maximum age to create a starting population.
Arguments
- species
Species for which population dynamics will be simulated. Choices include American shad (
"AMS"
), alewife ("ALE"
), and blueback herring ("BBH"
).- max_age
The maximum age of fish in the population(s). A numeric vector of length 1.
- nM
Instantaneous natural mortality rate. A numeric vector of length for (
"AMS"
or a vector of lengthmax_age
for"ALE"
and"BBH"
.- fM
Instantaneous fishing mortality rate. A numeric vector of length 1.
- n_init
Initial population abundance (includes all age classes).
