Abstract


Elacmen digestive yeast product consists of 4 categories of microorganism: L. acidophilus, L. sporognes, B. subtilis, S. cerevisiae in one manufactured product as well as Biozeo environmental treament product consisting 4 categories of microorganism: Nitrobacter sp, Nitrosomonas sp, B. megaterium, B. licheniformis, B. subtilis with suitable chemicals, when tested on shrimps and their habitat, has effective results. The rate of shrimps which can be produced reaches 50%, the rate of environmental measurements such as NH4+, NO2-, NO3-, in shrimp habitat decreases ard is more stable than in the given sample. As a result, all microorganism in the manufactured product can promote their effective actions and affect greatly the yield of shrimp raising.
