The geostatistical aggregation curve,P(T),describes the maximum proportion of fish that can be found in a certain proportion of area.It was described by the curve on the T-Pspace joining the points (T j ,P j ),j=1,2,…,n,where T j is the proportion of the total area occupied by population densities (z) larger than z,and P j is the proportion of fish that are encountered at densities larger than z.The T j and P j curves were respectively formulated as follows :
