An apparatus and method of reducing the effects of hydrodynamic forces of waves and water currents in coastal environments (e.g., oceans, and coastal, river, lake, and reservoir banks). The apparatus is an oysterbreak having two basic designs adapted to allow for the attachment of oysters and other bio-fouling marine organisms, using the least amount of material. In one embodiment, the oysterbreak comprises a support structure and plurality of slats (i.e., relatively planar sections or surfaces) having growth layers made from tubing coated with a material capable of inducing aquatic sessile organism attachment and growth. In another embodiment, the oysterbreak comprises a plurality (e.g., two, three, four, five, six, etc.) of growth layers of regular polygonal-shaped members made from a material capable of inducing aquatic sessile organism attachment and growth that when stacked, form a relatively portable, breakwater module.
