Ensuring a sustainable output from the Chinese coastal sea ecosystem is important to keep up with national demand. Enhancement and release of marine resources has become more and more important because of the continual decline in marine fishery resources. Studying the growth, distribution, feeding habits, and feeding competition of re- leased Chinese shrimp, Fenneropenaeus chinensis, provides a scientific basis for discussing the adaptability of an en- hance and release management strategy for Laizhou Bay. Nine bottom-trawl surveys were conducted in Laizhou Bay from May 2011 to April 2012, including March 21–27, April 19–23, May 6–11, June 9–12, July 8–12, August 1–5, September 6–11, October 19–23, and November 25–27. Chinese shrimp were caught only in four surveys conducted on July 8–12, August 1–5, September 6–11, and October 19–23. This result suggests that Chinese shrimp in Laizhou Bay mainly came from the enhance and release program. The instantaneous growth coefficient [(G = 100 × (lnW2 − lnW1)/t)] of the released Chinese shrimp showed that the shrimp grew fastest in July, and then the growth rate came to an inflec- tion point at the end of July or early August. Growth slowed thereafter. The distribution pattern indicated that the re- leased Chinese shrimp underwent an anadromous migration after a period of growth and adaptation, migrated from the river, and moved to deep water in early August. The released Chinese shrimp were concentrated in west Laizhou Bay in early August and in the bay mouth and west Laizhou Bay in mid-August, and mainly distributed in the bay mouth and outside of the bay in early September and mid-October. Ninety stomach samples were collected during the August 1–5 survey and were analyzed. The adult Chinese shrimp were omnivorous with a wide feeding range but were biased to- ward feeding on benthic prey. The feeding rate was 78.89%, and the feeding niche breadth was close to that of blue crab, Portunus trituberculatus. The dietary overlap index showed moderate or severe feeding competition between Chinese shrimp, blue crab, and eight other important fishery resource species in the Laizhou Bay community, including Clu- panodon punctatus, Oratosquilla oratoria, Synechogobius hasta, Chaeturichthys stigmatias, Charybdis japonica, Pa- laemon gravieri, Cynoglossus joyneri, and Callionymus beniteguri. Feeding competition was mainly associated with bivalve prey. According to growth, distribution, feeding habits, and feeding competition of the released Chinese shrimp, a preliminary discussion about adapting an enhance and release management strategy was conducted. Fishing for re- leased Chinese shrimp in Laizhou Bay began on August 20. However, the instantaneous growth coefficient of the shrimp at that time was about 1.7, and they showed a particular growth potential. Thus, fishing was appropriately post- poned to obtain higher yields later. The western part of Laizhou Bay remains the best location to release Chinese shrimp compared with the southern and eastern parts of the bay, but further study is required to understand the predators of re- leased shrimp larva. The current number of Chinese shrimp released into the bay appears reasonable based on the re- sults of prey resources and feeding competition analyses.
