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

Value

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