bh calculates the expected Beverton-Holt recruitment

Description

bh calculate the expected Beverton-Holt stock recruitment level from the available spawning biomass, the steepness, R0 and B0. This would be used when fitting a model to data.

Usage

bh(spb, h, R0, B0)

Arguments

spb

the current spawning or mature biomass

h

the steepness of the Beverton-Holt stock recruitment curve

R0

the unfished average recruitment level

B0

the unfished spawning biomass.

Value

the expected Beverton-Holt recruitment level, a real number in the linear scale

Examples

rec <- bh(10000,0.75,1500000,30000)
print(rec)   # should be 1285714
bh(spb=30000,h=0.75,R0=1500000,B0=30000)  # should be 1500000
