The study is done in order to survey biodiversity and distribution all kinds of clupeonela shapes and the kinds of clupedae in three forms like clupeonella engranli formis clupeonella grimmi and clupeonella cultiventris in two regions of Babolsar and Amirabad in Iran in number of 120 of fish by the conical net with light in 2010. For identification of species shape in Iran features are used. In this survey factors like total length, fork length, standard length,interorbital, head length, eye length, eye diameter, body depth, least depth of the caudal fin, length of the audal fin, breast area, number of kill, sex determination, age determination, predorsall length and weight are considered. In clupeonella engranli formis, fork length is 9.4 cm to 11.8 cm and in average 10.655 cm and body depth is between 1.7 cm and 2.7 cm which in average 2.181 cm, in clupeonella grimmi, head size is between 1.7 cm and 3.1 cm which in average is 1.99 cm fork length is 9.8 cm to 13.5 cm and in average 11.222 cm and eye diameter is between 0.3 cm and 1 cm in average 0.908 cm, head length is 1.7 cm to 3.1 cm and in average it is 1.99 cm. In species clupeonella cultiventris body depth is 0.7 cm to 2.2 cm and in average 1.848 cm fork length is 8.8 cm to 10.3 cm and in average of 9.484 cm head length is 1.1 cm to 1.6 cm with the average of 1.508 and eye diameter is between 0.2 and 0.3 and in average it is 0.268 cm.
