1986年夏季，琵琶湖流域南部湖水中溶解无机氮(DIN)的耗竭从8月中旬到10月上旬持续了两个月左右。在这种DIN耗竭开始的半个月后，鱼腥藻出现了水华，并持续了大约一个月。在鱼腥藻水华期间，总磷和颗粒磷的浓度都比前一时期高得多。因此，有人认为，除了DIN的枯竭外，从某个地方向湖水提供的磷刺激了鱼腥藻的大量生长。
In the summer of 1986, the depletion of dissolved inorganic nitrogen (DIN) in the lake water persisted for about two months from mid August to early October in the south basin of Lake Biwa. An Anabaena bloom appeared about a half month later from the onset of this DIN depletion and persisted for about one month. During the period of Anabaena bloom, both total and particulate phosphorus concentrations were much higher than in the preceding period. Thus, it was suggested that, in addition to the DIN depletion, phosphorus supply to the lake water from somewhere stimulated the massive growth of Anabaena.
