Two strong, contrasting management strategies were applied to Lake Ontario during the 1970s. There has been a 40 percent reduction in phosphorus loading to the lake and an exponential increase in salmonid stocking. A comparison of zooplankton community structure and abundance from 1981 to 1985 with that of earlier studies (1967 to 1972) found no detectable change in the range of abundances or community composition between the two periods. Clearly, neither management strategy has had a discernible impact on the zooplankton community to date; however, the potential for change in the system remains high. 36 references, 5 figures, 5 tables.
