The code for the masters thesis work with the above title. Contains a Novel HCR, which reflected an Escapement HCR, was tested on a stock whose dynamics was informed by Greenland halibut (Reinhardtius hippoglossoides). The code is implemented as a modification of the FLBEIA software (https://github.com/flr/FLBEIA).

3.3 Atlantis-R interface
Ibrahim Umar (IMR), Holly Perryman (IMR), Rebecca Gorton (CSIRO), Elizabeth A. Fulton (CSIRO)
The marine ecosystem model Atlantis is structured following the MSE framework, meaning Atlantis simulates both the operating model and the management procedure. This is an advantageous feature for simulating MSE under and ecosystem-based context, however it may be cumbersome to program complicated/specific management procedures into Atlantis. To integrate Atlantis into the REDUS framework, Atlantis was programmed to send/receive data back and forth with the statistical software R. With this new functionality, Atlantis can be treated solely as an operating model while R is used to simulate the management procedure. Thus, management procedures previously programmed in R can now be simulated under an ecosystem-based context within Atlantis.

GadgetR is an R library that allows users to create a two-way interface to the simulation function (via a “gadget -s” command line switch) of Hafro’s Globally applicable Area Disaggregated General Ecosystem Toolbox (Gadget) program. To simply put, GadgetR provides users flexibility to explicitly control gadget simulation steps, and inspect and modify (as needed) gadget internal objects (such as recruitment parameters, fleet consumption amount, among others) at any point in time during the simulation. These functionalities are especially useful when you want to use a gadget model as an operating model (single or multi- species) in existing management strategy (MSE) frameworks in R (FLR/mse or FLBEIA). GadgetR ships with the latest Gadget program (version 2.2.00-BETA) and retains all of the original Gadget program functionality.

3.6 MSE Framework
Ibrahim Umar (IMR), Daisuke Goto (IMR), Alfonso Perez Rodriguez (IMR)
FLR-Gadget is a Management Strategy Evaluation (MSE) framework using FLR (The Fisheries Library in R) mse (https://github.com/flr/mse) with an R package of customized Gadget (Globally applicable Area Disaggregated General Ecosystem Toolbox, https://github.com/Hafro/gadget2), GadgetR (https://github.com/REDUS-IMR/gadget), as an operating model (OM). This framework is designed to run single and multi- species MSEs. The OM can be age- or length- based. The framework runs short-cut and full-feedback MSEs. Currently, a4a (Assessment for All, https://github.com/flr/FLa4a) statistical catch-at-age model and SAM (State-space Assessment Model, https://github.com/flr/FLSAM) are implemented as an assessment model.
