Mean crowding values revealed differences in small-scale distribution of scallops that were undetectable with density estimates.
Distributions of juvenile and adult scallops were plotted across Georges Bank and tile Mid-Atlantic Bight, and mean density and mean crowding were calculated for juveniles and adults in both areas and years.
Crowding is the number of organisms found within a given proximity of an individual of interest, and mean crowding is the average of crowding values for all individuals in the study area.
Quadrat samples have been used to examine mean crowding values in scallop populations (MacDonald & Bajdik 1992).
With quadrat samples, however, the spatial distribution of individuals is unknown, and calculating mean crowding with an estimation of error is necessary.
