Is Metagenomic Analysis an Effective Way to Analyze Fish Feeding Habits? A Case of the Yellowfin Sea Bream Acanthopagrus latus (Houttuyn) in Daya Bay

Yellowfin seabream, Acanthopagrus latus , is one of the most important species in terms stock enhancement China. However, using metagenomic techniques to explore feeding habits and stomach microbiome yellowfin seabream still rare. The objective this work was study sea bream from Daya Bay through analysis different weight classes (?50, 50–100, >100 g). Whole-metagenome shotgun sequencing morphological observation were used investigate contents. dietary composition community A. examined. In study, 153 detected eukaryotic contents bream. At level, Mytilus edulis only identified by both observation. proportion fish bivalves over 98%, but diet changed little with body size. Larimichthys crocea Scophthalmus maximus Seriola dumerili abundant among all samples. total, 285 Bacterium 2013Ark19i, bacterium 2013Arg42i Acinetobacter baumannii first reported bream, microbiomes. There no difference biodiversity microbiomes sizes. Overall, mainly consists bivalves. use metagenomics a promising approach for assessing results derived can provide information evaluating ecology Bay.
