Abstract
The dynamic behavior of bacterial flora in the mass culture of larvae of Iwagaki Oyster, Crassortrea nippona was investigated with the addition of Nannochloropsis sp. culture fluids. Three additional methods were examined, 1) addition of Nannochloropsis sp. culture fluid (cell (+)), 2) addition of supernatant from centrifuged Nannochloropsis sp. culture fluid (cell (-)) and 3) no addition of Nannochloropsis sp. culture fluids as control.<BR>The obtained results are as follows;<BR>1) Growth and vital ratio of the larvae by means of added cells (-) are superior to those using other methods. 2) In the cell (-) system, it was found that Moraxella sp. becomes preponderant over Vibrio sp., regardless of initial conditions of bacterial florae in cultivation water, and this dynmic behavior of the bacterial florae is favorable for the mass culture of larvae.
