Generate recruitment for a simulation year

Takes deterministic recruitment from sim_det_recruitment, multiplies it by the year's lognormal deviations from draw_sim_rec_devs, apportions it across sexes and seasons, and writes it into the age-one slot of sim_env$NAA, with NAA0 synchronized to match. A Rec_input covering year y overrides the draw entirely.

Usage

generate_recruitment(y, sim, sim_env, seas = 1)

Arguments

y

Integer. Year index.

sim

Integer. Simulation replicate index.

sim_env

Simulation environment from Setup_sim_env, modified in place: $ln_RecDevs, $Rec, $NAA and $NAA0.

seas

Integer. Season this recruitment first enters in, through rec_seas_prop[p, seas, sim]. Default 1, the classic rec_lag >= 1 case where the whole year's recruitment is known before season one. rec_lag = 0 instead calls this with seas = spawn_seas, the earliest season this year's own SSB is knowable. See apply_pop_dy.

Value

invisible(NULL); everything is modified by reference within sim_env.
