LatA: LatA Simulated length-at-age for 358 female fish

Description

A data.frame containing the simulated age for an array of different lengths based upon the properties of an extensive collection of redfish (Centroberyx affinis) length-at-age data from eastern Australia sampled in the 1990's.

Format

A data.frame with 358 rows and 2 variables:

age

simulated ages in years

length

consequent simulated fork length of the fish, in cms

Subjects

• Estimating individual growth from length-at-age data

• von Bertalanffy growth curve

• Gompertz growth curve

• Michaelis-Menton curve used as a growth curve

Examples

# NOT RUN {
  data(LatA)
  pars <- c(27.0,0.15,-2.0) # von Bertalanffy
  bestvB <- nlm(f=ssq,funk=vB,observed=LatA$length,p=pars,
                ages=LatA$age,typsize=magnitude(pars))
  outfit(bestvB,backtran=FALSE,title="vB")
# }
