ABSTRACT:
A method of and apparatus for raising shell fish such as giant clams wherein fertilized eggs are obtained under laboratory conditions and then placed in a larvae tank. The tank float in sea water and has a platform base adapted to support juvenile clams during growth and flexible non-permeable side walls suspended from a ring of floats. The weight of the base tensions the side walls to a desired degree, allowing natural ocean movement to be transmitted to the water within the floating tank. At predetermined growth stages filtered ports are opened in the side walls allowing ocean water to flow through the larvae tank.
