carpIPM R code

Fish grow continuously. Integral projection models (IPM) model size continuously. We developed an IPM for fish. We specifically developed the model for grass carp, however, the model could also be applied to species with similar life-histories such as other carp species. We included YY-males within the model because releasing YY-males has been proposed a control method for the species. YY-males are fish that have 2 male chromosomes compared to a XY-male. When YY-males mate, they only produce male (XY) offspring. This decreases the female proportion of the population and can, in theory, eradicate local populations by biasing the sex-ratio. We created our model as an R package and the model has been documented by both a TRACE Document and peer-reviewed manuscript.
