Two stations were sampled one in the treated and in the reference both fairly near the curtain in the middle of the lake. The samples were taken with a 30 cm diameter plankton net with 335 um mesh plankton netting. In almost all cases replicate vertical tows were taken with the length varying on the depth of the lake. The entire sample was surveyed for the 3 large species- D. middendorffiana, Heterocope, and Holopedium. All of the samples were counted and enumerated by Sun Yong.
