In jabbamodel/JABBA: Just Another Bayesian Biomass Assessment

jbleslie

Description

Function to compute r, generation time (gt) based on female life history

Usage

jbleslie(bio)

Arguments

bio	list of history parameters if fecundity is provided (e.g. pups per females) it will be used directly if fecundity is NULL, a BevHolt as a function is used to compute the annual reproductive rate

Value

list r, gt

Examples

#Blond ray
# Use fecundity: 30 per female
bio.fec = jbio(amin = 0,amax = 20,Loo = c(154.7),k=c(0.129),t0=c(-1),aW = 0.01,bW=3.04,mat=c(5.5,6,1),M=c(0.26),fec=32,empty=FALSE)
jbleslie(bio.fec)
# Use steepness: h = 0.5
bio.h = jbio(amin = 0,amax = 20,Loo = c(154.7),k=c(0.129),t0=c(-1),aW = 0.01,bW=3.04,mat=c(5.5,6,1),M=c(0.26),h=0.5,empty=FALSE)
jbleslie(bio.h)
#
# Thornback ray
# Use fecundity: 100 per female
bio.fec = jbio(amin = 0,amax = 18,Loo = c(117.6),k=c(0.16),t0=c(-1),aW = 0.01,bW=3.04,mat=c(5.3,5.8,1),M=c(0.32),fec=100,empty=FALSE)
jbleslie(bio.fec)
# Use steepness: h = 0.5
bio.h = jbio(amin = 0,amax = 18,Loo = c(117.6),k=c(0.16),t0=c(-1),aW = 0.01,bW=3.04,mat=c(5.3,5.8,1),M=c(0.32),h=0.5,empty=FALSE)
