Calculage growth trajectory using the biological intercept model
Description
Uses a biological intercept model (BIM) to calculate the growth at age for the full life history of a fish. It requires the fork length of the fish at capture (fl), the length at hatch for the species (hl) and the otolith radius trajecotry (gt).
Usage
bim(fl, hl, gt)
Arguments
fl |
Fork length of a fish as measured at time of capture. |
hl |
Length at hatch for the species of interest |
gt |
The full otolith radius trajectory for a given fish. At a minimum, the minimum radius, maximum radius, and radius of interest must be supplied (for example, total otolith radius, radius at age 0, and radius for a given age can be supplied if you only want to know the size at a specific age). |
