Resting cysts collected in the autumn from bottom sediments were stored in the laboratory, in the dark at 4 degrees C, through the winter. Over a six month period, toxicity of the stored resting cysts was compared with toxicity of cysts from freshly-collected sediments. Resting cysts retained toxin over the winter months. Toxin levels show an apparent rise. Toxicity measurements of cysts from sediment samples kept in the laboratory reflect in situ levels.
秋季从底部沉积物中收集的休眠孢囊在实验室中于4摄氏度黑暗条件下储存过冬。在六个月的时间里，将储存的休眠孢囊的毒性与从新采集的沉积物中获得的孢囊的毒性进行了比较。休眠孢囊在冬季的几个月里保留了毒素。毒素水平有明显上升。保存在实验室中的沉积物样本中孢囊的毒性测量结果反映了原位水平。
