Calculate Recruitment (Version 1)

Usage

get_recruitment_v1(y, sbio, B0, alpha, beta, sigma_r, rdev_y, sr_dep = 1e-10)

Arguments

y

An integer scalar, year index.

sbio

A numeric scalar, spawning biomass for the year.

B0

A numeric scalar, unfished spawning biomass.

alpha

A numeric scalar, Beverton-Holt alpha parameter.

beta

A numeric scalar, Beverton-Holt beta parameter.

sigma_r

A numeric scalar, recruitment standard deviation.

rdev_y

A numeric vector of length n_year, recruitment deviations.

sr_dep

A numeric scalar, depensation threshold (default 1e-10).

Value

A numeric scalar, predicted recruitment for the year.

Legacy status

These functions reproduce historical version-1 assessment code for audit and comparison. They are not the production SBT objective, do not implement the current data, mortality, harvest-wall, or biological-state contracts, and receive only compatibility maintenance. New analyses should use get_data(), sbt_model(), and the current component helpers.
