jbio()

Description

Creates a list for JABBA-Select stock object as input for the ASEM

Usage

jbio(
  amin = 0,
  amax = 10,
  nsexes = 2,
  nseas = 1,
  Loo = c(80, 65),
  k = c(0.2, 0.25),
  t0 = c(-0.5, -0.7),
  aW = 0.01,
  bW = 3.04,
  mat = c(40, 45, 0),
  M = c(0.3, 0.4),
  h = 0.7,
  fec = NA,
  empty = FALSE
)

Arguments

amin	minimum age
amax	maximum age
nsexes	if nsexes = 2, values are in order female, male
Loo	asymptotic length
k	brody growth coefficient
t0	theoretical age at zero length (vb growth)
aW	parameter of length-weigth Wa = aW*La^bW
bW	parameter of length-weigth Wa = aW*La^bW
mat	c(lm,dm,0=len or 1 = age) logistic maturity ogive parameters m50 - age or length m95 - age or length P(mat) = 1/(1+exp(-log(19)*(x-m50)/(m95-x))) x - age or length
M	Natural mortality (vectors of M at age can be adjusted after stk is created)
h	steepness of BevHolt SSR
fec	number of offspring per female - for sharks and rays
empty	produces an empty list structure based on amin:amax if TRUE

Value

jbio List of life history vectors and matrices
