Abstract
Abstract An artificial fish farming nest. The nest is formed in the shape of a dome and has a plurality of holes through the wall of said dome. The dome is submerged so that its edge is placed on the bottom of the sea, thereby giving buoyancy to the fish farming nest itself and thus preventing it from being buried in the bottom of the sea within a short space of time.
