Initializes a population for a given virgin biomass.

Description

Abundances at age for a population at virgin conditions at age. An FLBiol object is initiated by providing a target total biomass (B0) and a value for the stock-recruit steepness (s). The object requires slots to be already filled up for the mean weight-at-age (wt), natural mortality (m), time of spawning (spwn) and maturity at age (mat).

Usage

initiate(biol, B0, h = 0.75)

Arguments

biol

An FLBiol object to nbe initiated.

B0

Initial or virgin biomass.

Value

An updated FLBiol with abundances set in teh first year to match the requested biomas.

Examples

data(ple4.biol)
initiate(ple4.biol, B0=450000)
#
initiate(propagate(ple4.biol, 100), B0=runif(100, 3e5, 5e5))
