Abstract

This study examines features such as the population structure, growth and reproduction of the pearl mullet captured in the Lake Ercek. Between the dates January 2008 and January 2010 a total number of 527 individual were sampled through using trammel net and mesh size of 20,22 and 24 mm of fish net.
