Abstract

This study was showed Some biologycal aspects of the first stages of Bunnei (Barbus sharpeyi) and Common carp (Cyprinus carpi) in the earth pond. These two species was produced in Marine Science Freshwater hatchery. The Length-Weight relationship for Barbus sharpeyi W= 0.0111 L2.9662 and for Common carp W= 0-05 L2.9524The average relative growth reached its highest value for (4890) and (8275) for Bunnei and Common carp respectively. The highest value for specific growth was (14.7) and (14.4) for Bunnei and common carp respectively. The highest average weight for common carp was (3930) mg and highest average of length (63) mm. while The highest average weight for Buni larvae was (1470) mg and highest average of length (53) mm after 42 days.
