摘　　要：Drag forces acting on Schlegel’s black rockfish Sebastes schlegeli were studied. A new drag force transducer was designed and used to measure the water drag on Schlegel’s black rockfish in a vertical recirculating flume tank. Fourteen individuals were investigated, yielding two mean drag coefficients referred to the cross sectional area and volume 2/3 respectively at water velocities ranging from 0.3 to 1.0 m s -1 . The drag coefficients can be used for estimating the drag forces acting on Sebastes schlegeli in water.Drag forces acting on Schlegel's black rockfish Sebastes schlegeli were studied.
