The Least Cisco

Least Cisco is a northern whitefish found in freshwater and some coastal-connected populations. Resident and migratory life histories occur within its broad Arctic distribution.

Arctic Distribution

The range spans northern Eurasia and North America, including Siberian, Alaskan and Canadian waters. These are many distinct populations rather than one uniform stock. A drainage and locality are important when interpreting differences in movement, growth and feeding.

Movement Patterns

Some populations remain in fresh water, while others make broader movements connected with coastal feeding or river spawning. Long migrations reported from one river should not be assigned to every lake resident. Preserve the population context with any account of seasonal travel.

Food and Measurements

Zooplankton and insects are recorded foods, with other items also taken. Spawning occurs over sand or gravel in river pools in reported accounts. The compiled maximum is 47 centimeters total length. A limited sample weight is not retained as a universal upper limit for all populations.

Identify Resident or Migratory Context

The same species can have different movement patterns. Keep a fish’s lake or river population with its life-history and size information.
