Description Usage Format Source Examples

Description

Synthetic length-frequency data as generated by the function virtualPop2 from the fishdynr package (Taylor and Mildenberger, 2018). Can be used by ELEFAN, ELEFAN_SA, or ELEFAN_GA. The data is generated with the following von Bertalanffy growth parameters:

Further settings include:

The average biomass relative to the unfished biomass and the yield per recurit for the years, 2014, 2015, 2016, 2017 is 0.16, 0.21, 0.41, 0.75, and 0.4, 0.43, 0.24, 0.07, respectively. Biomass over Bmsy as estimated with a surplus production model is 0.51, 0.67, 1.27, 2.18. Lopt is 53.33 cm.
