Feeding is an important behavior for the growth and reproduction of fish. The nutrient niches of different areas and the distribution of main feeding grounds can be understood by analyzing the spatial heterogeneity of the feeding habits and growth rates of fish species. Based on samples collected from bottom trawl surveys in Haizhou Bay during the springs of 2011 and 2013-2016, the feeding habits of were studied by analyzing their stomach contents. The spatial heterogeneity of feeding habits and feeding grounds was identified by analyzing the distribution of and its major prey species. The results showed that prey items of included 20 species, with decapoda and amphipoda being the most predominant prey taxa. Based on stomach content and bottom trawl survey data, eight major prey items, including Alpheus distinguendus, Metapenaeopsis dalei, were selected to examine the spatial heterogeneity of the feeding habits and feeding grounds of % for the eight major prey items were 35.95%, 55.67%, and 44.59%, respectively. The spatial heterogeneity of feeding habits indicated that . Compared with results from previous studies, our results showed that the dominant prey items of had changed; this change was not only affected by the inter-species relationships in the ecosystem, but also by the fluctuation in the abundance of dominant prey items in Haizhou Bay. In addition, according to the abundance of these major prey items, the survey stations were divided into two areas (area I and area II) based on hierarchical cluster analysis. Except for , the abundance of the other six prey items in area I was higher than that in area II. In area I, the body length of ranged from 52 to 125 mm, their average body length was (86.67±0.28) mm, their body weight ranged from 2.15 g to 33.76 g, and their average body weight was (11.94±0.12) g. In area II, the body length of the ranged from 47 to 138 mm, their average body length was (95.80±0.12) mm, their body weight ranged from 1.74 g to 39.59 g, and their average body weight was (14.75±0.05) g. Our results showed that the <0.05), whereas in area II (2.90) it was significantly lower than 3 ( and its eight major prey species were more abundant in the 10~20 m depth sea area in the center of Haizhou Bay; the abundance of prey in the 10~20 m depth sea area in the center and south of Haizhou bay (area I) was higher than that in other areas ( in this area were smaller and fast-growing. Therefore, this area was identified as the feeding and nursery ground of in Haizhou Bay during the spring.
