In some embodiments, an apparatus for aquaculture includes a support structure defining an interior region. The support structure includes a first support member disposed in a first plane, a second support member disposed in a second plane orthogonal to the first plane, and a third support member disposed in a third plane orthogonal to the first plane and the second plane. A mesh material is disposed in the interior region of the apparatus and is coupleable to the support structure. The mesh material defines a containment volume suitable for cultivating aquatic organisms. A plurality of tensioning members are configured and disposed to couple the mesh material to the support structure. Each of the tensioning members are coupled to the mesh material and at least one of the first, the second and the third support member, and configured to provide tensile loading on the first, second and third support members.
