- In Lake Nipissing, Ontario, larger ciscoes (which migrated early to the
  hypolimnion) fed almost continuously from spring to mid-September on
  plankton crustacea with high fat content.  Ciscoes remaining longer in 
  shallow water ate large numbers of emerging mayfly for a short time,
  but then fasted for a few weeks after migration into the hypolimnion.  A 
  marked increase in growth of older ciscoes was probably the result of
  feeding upon abundant Diapto oregonensis in deep water all summer.

- Lake whitefish (similar to lake trout, longjaw cisco, and lake herring) are
  cold stenotherms at the southern edge of their zoogeographical ranges.  Lake
  whitefish require cold, adequately oxygenated bottom waters for a summer 
  habitat, and a mostly silt-free river or lake-spawning area for successful
  reproduction.  Year-class success is the result of favorable environmental
  conditions rather than of spawning-stock size.

- Differences in bottom characteristics indirectly influence distribution of the

  are confined to a bottom strata of water no more than 1.5 m deep.  In this 
  stratum, food consists mainly of various species of Crustacea and Mollusca.
