The length-weight relationships (LWRs) of Clupeonella cultriventris and Clupeonella
muhlisi were analysed. Fish samples were collected gill nets (10 mm mesh sized) from the
Büyük.ekmece Reservoir and Kü.ük.ekmece Lagoon April and June 2016. Samples from
Durusu Reservoir and Uluabat Lake were obtained from Istanbul University Science
Faculty Hydrobiology Museum. The values of parameter b in the LWR equations varied
from 3.177 (Kü.ük.ekmece Lake population) to 3.496 (Büyük.ekmece Reservoir
population) for C. cultriventris and 3.258 (Uluabat Lake) for C. muhlisi.
