Abstract: The shrimp community features including species composition， dominance species， and diversity as well as similarity of community structure and relationship between community structure and hydrological environmental factors were evaluated by the data from 15 positions by using bottom trawling around Pishan area in Yushan fish ground in November of 2015 and February， May， and August of 2016.A total of 15 species were found， belonging to 11 genera in 8 families， with dominance species of Exopalaemon carinicauda， Parapenaeopsis hardwickii， Solenocera crassicornis， Parapenaeopsis tenella， Acetes chinensis， Palaemon gravieri and Alpheus japonicus.The shrimp species composition was varied with seasons， resulting in the big difference in the composition of dominant species，with the maximal number of shrimp species in autumn and the minimal number in winter.There was the maximal number of dominant species in spring and the minimum in winter.The shrimp species and number in the catches were changed with water depth， with the most species at depths of 20－30 m and the minimum at depths of 30－40 m.There was lower Shannon－Wierer diversity index of shrimp community in winter than in other seasons， and decline with water depth， less at 5－10 m and more at 5 m.The findings indicate that water depths， temperature and salinity are the main environmental factors influencing species composition and feature of shrimp community structure.
