Development of a Recirculation System for the Mass Culturing of the rotifer Brachionus plicatilis

Gede Suantika’s research looks at the culturing of small planktonic organisms (rotifers) which are used as food in the cultivation of larval fish and shrimps. The research deals more specifically with the development of a recirculation system for the mass culturing of the rotifer Brachionus plicatilis. In South-East Asia, the cultivation of tiger shrimp (scampi) has expanded enormously over the last ten years, and has become a significant factor in the economies of various countries. One of the main expenses in the production of shrimps is the cultivation of the young stages, primarily due to the high cost of feeding, as the food consists of live prey which also has to be cultivated, often under very difficult circumstances. The author now introduces Western technology, opening up the possibility of producing these food organisms in a much more profitable way. The technology he develops is high-tech and innovative, but it is also easy to use in developing countries: the research covers as many aspects as engineering, water quality, zootechnics and business economics. In principle, complex electronics are not required: the methods used involve pumps and peripheral devices which are obtainable everywhere. The high-tech element lies primarily in the intensity of knowledge required for the development of this technology. Through this study not only has a technique been designed with is practicable, but a country such as Indonesia also acquires the necessary technical knowledge in-house.
The originality of the research lies, among other things, in its analyses of the microbial biota in these recirculation systems.
