An accelerated motion of conical net is associated with a reduction of water velocity inside the net. Water mass retained inside the net will move with the towed net. This water mass is defined as the added mass. In order to evaluate the added mass of the conical net, ten models of different mesh factors and attack angles were tested in a large scale towing tank at the National Research Institute of Fisheries Engineering. The measured added mass is then converted into dimensionless added mass coefficient using the volume of the conical net and the mesh factor. The added mass coefficients of conical nets can thus be compared by type of models and evaluated.
