RRK: Ricker Recruitment Model

In IMPRESSPROJECT/ModelingPopulation: Modeling of an exploited population (structured by age)

Description

Computes the recruitment using Ricker Model.

Usage

RRK(SSB, a, b)

Arguments

SSB	Maturity biomass for each year (spawning stock)
a	Recruits-per-spawner at low stock levels.
b	Relates to the rate of decreasing of recruits-per-spawner as SSB increases.

Details

The formulation of the Ricker equation is:

R=a*SSB*exp(-b*SSB)

where SSB is the Maturity biomass (spawning stock), a is the recruits-per-spawner at low stock levels and b relates to the rate of decreasing of recruits-per-spawner as SSB increases.

Value

Vector containing the recruitment for each year.
