NOTE: This project is in maintenance mode. Further development (backwards incompatible) of more general models is occuring on:

https://bitbucket.org/autocatalysis/model_fishery

This github instance is here to serve as a reference for the online manuscript on bioRxiv (see below).

Dynamical models for fishery assessment

They are made possible by some excellent work:

Julia
SciML
Turing
DifferentialEquations
Other important libraries used can be found in the set up environment (*.environment.jl) for each project.

Current results:

Results based upon this developmental branch.
They are generated by the main calling program.

Models currently implemented:

Discrete logistic (Euler form)
Discrete logistic map
Six sex/size-stage continuous delay differential equation model

Example data are in RData form:

biodyn_number_size_struct.RData
- time series by large areal units, number, size, habitat, etc.
- used by stage structured models
biodyn_biomass.RData
- time series by large areal units in biomass
- used by logistic models

Documentation:

An example using this approach is found here for snowcrab. It is now grafted onto bio.snowcrab for operational work (as of Jan 2023)

Current documentation is here.
