Growth, Diet and Fatty Acid Composition of Gibel Carp Carassius Gibelio in Lake Shira, a Brackish Water Body in Southern Siberia
For the first time the presence of gibel carp Carassius gibelio has been detected in the brackish meromictic Lake Shira (Southern Siberia, Republic of Khakassia). Lake Shira has been continuously studied since the late 19th century, and it has been considered so far that there is no ichthyofauna in...

The food spectrum of one- and two-year old C. gibelio was dominated by diatomic, green and blue-green algae, while four- to sixyear old species had an increased share of copepods, beetles and chironomids in their food spectrum, and beginning from the age of six years the amphipods Gammarus lacustris consisted significant part of gibel carp diet.
