Multi-Species Virtual Population Analysis eXtended 2

The Multi-Species Virtual Population Analysis tool is a Qt/C++ implementation of the Visual Basic tool written by Dr. Lance Garrison about 20 years ago. This tool is a series of single-species virtual population analysis (VPA) models linked by a simple feeding model to calculate natural mortality rates. A VPA is the process by which a population size is inferred to have been a certain size in the past in order to support the observed fish catches and natural mortality.
