unitarea

is the unit area used for estimating density of lobsters.

initlambda

is the density of lobsters at the beginning of simulation.

initD

is the dispersion index of lobsters on seabed at the beginning of the simulation.

lobsterSizeFile

is a csv file that contains the frequency of lobsters size class.
