The first part of this study on the development of fish rearing tanks was concerned with reviewing previous designs and techniques (Klapsis and Burley, 1984). From this study it was made clear that several objectives have to be simultaneously satisfied or at least attempted within such a design and these have been clearly enumerated. In the second part of this study an investigation is reported on a simple re-design of a square tank which offers a 21% increase in useable surface area over an equivalent circular tank. With an asymmetrical square tank, the axial symmetry of a circular tank no longer applies and several important design changes need to be introduced. The design modifications proposed and implemented in this case were found to give fairly constant fluid velocities at all cross-sections, together with excellent mixing, self-cleaning and aeration characteristics in the body of the fluid. © 1985.
