are supplemented by release of hatchery individuals in Xiangshan Bay. There is little information describing the basic biology of , which hinders efforts to improve the supplementation programN. albiflora from Xiangshan Bay between October 2011 and September 2012, and analyzed the stomach contents and the prey species from them. We used dietary prey species percentage in weight, dietary prey species percentage in number, and occurrence frequency of species in stomach content to analyze the organism composition in diets. We used the importance index (IRI) and IRI% to determine the importance of the prey species in diets, used the empty stomach rate and stomach fullness index to evaluate the feeding intensity of fish, and used selection index selection. , suggesting it was a generalist. Shrimps were the dominant prey groups. At the species level, the main prey items were Oratosquilla oratori, . Feeding activity varied seasonally and with ontogeny. The feeding intensity was lowest in winter and in large-sized individuals (>190 mm). Feeding activity was also correlated with gonad maturation. The diet composition of was similar in autumn, winter, and spring, consisting primarily of , Palaemon macrodactylus, . Shrimps were the dominant prey groups of Oratosquilla oratori were the dominant prey groups of large-sized individuals (>220 mm).Palaemon macrodactylus0.145, V=0.141, was abundant in the environment, but it was negatively selected in the diet (N. albiflora. The feeding selectivity of was related to the composition and individual size of food organisms in the environment. To a certain degree, the prey animals’ ability to escape predators and the length of the individual also affected the feeding ecology ofN. albiflora has abundant feed resources and the prey species are various, and the composition of prey species and feeding intensity in different season or different body size class are variational, and this species has a unique feed selection and ecology. It suggests that the distribution of prey organism forin Xiangshan Bay should be considered during the selection of releasing scope, releasing season and releasing spot for the purpose of conservation and enhancement of this species.
