Abstract:

Populations of plankters in eight ponds containing several species of fish on the Auburn University Agricultural Experiment Station, Auburn, Alabama, were sampled from June to October, 1969. Four of the ponds were aerated artificially and four were non-aerated. One of the non-aerated ponds was not stocked with any species of fish. Monthly plankton samples were taken with a Van-Dorn plankton sampler and analyzed in a Sedgwick-Rafter counter cell with a Whipple ocular micrometer. The average number of organisms per liter were calculated for each depth of each station. This experiment indicated that aeration resulted in uniform distribution of temperature and dissolved oxygen. Cladocera, Ostracoda and total phytoplankton population were more abundant in aerated than in non-aerated ponds. Copepoda and larvae of were more abundant in non-aerated than in aerated ponds. Rotifers were most abundant in the stations farthest away from the blowers in aerated ponds. However when average numbers per liter for entire ponds were considered no differences between aerated and non-aerated ponds were apparent.
