Comprehensive assessment of population genetic structure of the overexploited Japanese grenadier anchovy (Coilia nasus): Implications for fisheries management and conservation
Japanese grenadier anchovy, Coilia nasus, is a commercially important fish species in China. Three ecotypes (anadromous, landlocked and freshwater-resident populations) are distributed across its range. Due to anthropogenic activities such as overfishing and habitat deterioration, the stock status o...

Japanese grenadier anchovy, Coilia nasus, is a commercially important fish species in China.
