Under these assumptions, the lack of fit of the autoregressive model must be the
consequence of exogenous factors to the fishery and biological parameters. In this
way it is possible to find some type of correlation patterns (linear or nonlinear)
between the autoregressive residual series and time series of environmental
parameters.
19.6.8 SimFish Data, Parameters, and Simulations
Like Gadget, SimFish requires several parameters about the Blackspot Seabream
biology like the population growth model or the population structure composition
and different experimental relationships as the established between length and
weight or length and fecundity. Additionally, it is necessary to take into account
that the Blackspot Seabream is a protandric hermaphrodite species but is functionally gonocoric (Alcaraz et al. 1987). That is, the young individuals are functional
