An aquaculture container for raising shellfish is formed of a homogeneous, monolithic monocoque shell by forming one or more openings therein and installing screen, net, or mesh over the opening(s). The container may be formed of a plastic 55 gallon barrel or drum, or other shapes, sizes, and configurations of containers may be used alternatively. The container has at least one panel or end which is removably secured thereto, for access to the interior thereof. An insert may be removably installed within the container to provide additional internal surface area for shellfish, as well as support for nutrients added to the container. The internal surfaces of the container shell and insert preferably roughened in order to provide a better grip for the attachment of shellfish thereto, particularly for shellfish such as abalone which remain mobile throughout their lives. Preferably, all of the components of the container are formed of plastic or at least a non-corrosive material, to preclude corrosion or deterioration in a salt water environment. The plastic material allows the container to be constructed using a plastic welding method. The present container with its roughened interior and additional surface area provided by an insert therein, is particularly well suited for growing abalone which remain mobile throughout their lifespans, but may be used for growing other shellfish which essentially immovably affix themselves to a surface during at least the adult portions of their lifespans.
