Value

a list of new coordinates, number of catch and their sizes

Arguments

Lobster: is the x & y coordinates of each lobster
Trap: is the x & y coordinates of the trap
trapCatch: number of trapped lobster
lobSize: Size of trapped lobster
lobSex: Sex of trapped lobster
radiusOfInfluence: is the initial radius of influence
currentZoI: is the bait's area of influence at each timestep
dStep: is how much a lobster moves in each time step
howClose: The area within which a lobster considered trapped
q0: is the initial probability of entry into an empty trap
qmin: is the asymptotic minimum probability of entry
saturationThreshold: is the number of lobsters in a trap at which the probability of another lobster entering the trap is zero
trapSaturation: Logical. If TRUE, lobsters behavioral interaction is included during the simulation.
lengthBased: Logical. If TRUE, lobster size is taken into account
lobLengthThreshold: is a size threshold (Carapace Length in mm), if a lobster larger than this threshold caught there will be no more entry to the trap
sexBased: Logical. If TRUE, lobster sex is taken into account and user must provide a list containing sex distribution for the simulated population
