Composition, Demographic History, and Population Structures of Trichiurus

Sequences of the complete mitochondrial cytochrome oxidase subunit I gene were used to identify Trichiurus species and examine their population genetic structure demographic history along coast China. Three found. japonicus lives in colder waters continental shelves China Seas, while nanhaiensis warmer slopes South Sea, brevis shallow Sea. The migrations these mainly associated with feeding spawning preferences. Two major wintering grounds East Sea All showed a lack resulting from oceanodromous life cycle (the degree substructure index N ST = 0.000–0.149), but results approximate Bayesian computational approaches suggested declines or stabilization differentiation. T MRCA (time most recent common ancestor) that during glaciations, Yellow completely exposed, acted as refugium. Thus, populations three experienced differentiation glaciations. This study also examined limitations skyline plot analysis.
