The fundamental equations of multi-species virtual population analysis and its variants

Finally, I discuss (1) the conversion of data on the stomach contents of fish of different ages and of different species into their coefficients of suitability, (2) two possible extensions of the present work, (3) its general ecological and biological significance as a much needed practical method or routine for parameterizing a system of age- and time-dependent or more general Lotka-Volterra equations to understand the underlying mechanisms for the rapid changes of the ecosystems and for us to maintain a harmonious co-existence within a biological system, and (4) its significance to several areas of fisheries science, including food production, effective use and management of fisheries resources, marine and freshwater conservation, and the maintenance of a healthy aquatic environment.
