What is FLR?

• Fisheries Library in R
• Provides extensible toolbox for Management
  Strategy Evaluation (MSE)
• For example
• fit stock-recruit relationships and model
  biological stocks
• model fleet dynamics (including economics)
• simulate management procedures (harvest control
  rules)
• Not just stock assessments (XSA, ICA etc.)
• Etc

Philosophy of FLR

• Open source license (GPL) you can modify a copy
  of the code, but you must distribute it under the
  same license.
• Collaborative Discussions are open (mailing
  list), website is editable, external review is
  encouraged
• Breaking the barrier between user and developer
• Improves inter-disciplinary dialogue

4
Design principles

• Object Oriented Programming
• Different elements of system are treated as
  objects, e.g. stocks, fleets
• Each object stores data and has functions that
  act on that data
• Objects can be linked together to create
  simulations
• Lego blocks
• Learning curve trade-off between flexibility and
  simplicity
• Uses R inbuilt graphical and statistical
  routines
