In this study, the population pattern intensity of Parapenaeus fissuroides Crosnier in the northeast Fujian sea area was investigated with the negative binomal parameters, average crowding degree and poly block indices. The Paper also further discusses the driving factors of the population pattern intensity. In spring, the population primarily consisted of small patches, population aggregation was low, and individualmean crowding was the lowest of the year. In summer, population aggregation and individual mean was highest. In fall, the population primarily consisted of a small number of large patches. In winter, population aggregation was the lowest. The zooplankton biomass (feed) and water temperature were the major factors affecting population aggregation.
