dc.description.abstract Larvae of the phantom midge, Chaoborus, are nocturnally active, acid-tolerant zooplanktivores whose abundance varies widely in Canadian Shield Lakes. They are known to influence the competitive interplay among dominant zooplankton species, perhaps complicating the interpretation of changes in zooplankton community structure that accompany acidification of lakes. Therefore, estimates of Chaoborus abundance may greatly aid interpretation of patterns in zooplankton communities observed over gradients of lake alkalinity. A summary of field and laboratory methods employed during a fall, 1986, larval Chaoborus survey of 18 Muskoka-Haliburton Lakes is presented. Raw data and four estimates of average Chaoborus abundance and biomass are presented for each lake.
