AbstractDynamic models are described for two applications in aquacultural engineering : mussel longline systems and fish nets. The mussel longline is modeled using lumped masses and tension-only springs. The mussel culture and attached buoys are modeled as cylinders attached to the main line. The fish net is modeled as an inter-connected system of lumped masses and tension-only springs. Surface waves are described by Stokes? second order wave theory. The hydrodynamic loads are applied via a Morison?s equation approach using the instantaneous relative velocities and accelerations between the fluid field and the structural system. The equations of motion are formulated for the coupled dynamics of the masses in each system.
