Estimate Growth Parameters Length Frequency Data #105

Closed MLV99 closed 1 year ago

MLV99 commented 1 year ago

I have length frequency data (no age data) and I need to extract the growth parameters of VBGF to eventually create a length converted catch curve.

I have read the literature and the available functions in the TropFishR and FSA package yet I still cannot make it work for my data and I am also new to R studio.

Example of data: df

length | freq 210 | 2 220 | 7 230 | 3 240 | 13 250 | 33

What function should be applied?

Any help is appreciated

Hi, Unfortunately, the growth models in FSA require length and age. I would suggest checking out the TropFishR package which has numerous functions for analyzing length frequency data. https://github.com/tokami/TropFishR Jason
