simGrowth: Simulate growth parameters

In danStich/shadia: American shad dam passage performance standard model for R

Simulate growth parameters

Description

Internal function used to simulate sex-specific length at age from sex-specific von Bertalanffy growth functions (VBGF) incorporating effect of sst on VBGF parameters L-infinity and K.

Usage

simGrowth(region, female = TRUE)

Details

This function relies on model estimated VBGF parameters from the 2020 Atlantic States Marine Fishery Commission American shad stock assessment. The VBGF was fit using SST as a continuous predictor of parameters Linf and K in the model. We use these relationships to predict new values of Linf and K from projected sea surface temperatures with stored posteriors from built-in, sex-specific data sets containing VBGF parameters.

Value

A numeric vector of length 1 containing one sample of simultaneously estimated VBGF parameters (as a random draw from fitted model posteriors).
