| Abstract | ||
| In the plan of developing aquaculture and increasing production in the lake behind Golabar dam in Golabar village of Ijroud city of Zanjan province, plankton studies were considered as basic studies to increase fish production in this lake. In this project, 5 study stations were considered in the area of the dam lake and the river entrance. The studies started quarterly from the fall of 2009 and continued for one year until the summer of 2010. For sampling of zooplankton in the dam lake by a 55 micron Juday net was taken from the floor to the surface of a sample of water column, at the entrance of the river by a P.V.C pipe 30 liters of water was filtered by a zooplankton net. finally samples were stabilized with %4 formalin rate and transferred to laboratory for study. In zooplankton studies, a total of 5 zooplankton Phyla and 25 genera were identified, with the highest percentage of the zooplankton population belonging to the Rotifera phylum, which includes %76.2. The most important genera in this group are Polyarthera, Keratella, Filinia and Pompholyx. Comparison of planktonic observations with physical and chemical data of water shows that due to the young age of Glabar Dam Lake, it is equal to the amount of nutrients and organic matter in the Eutroph waters, and This reservoir has talent suitable zooplankton species for feeding, breeding fish and their larvae , so the natural resources of this water source can be used to increase the production of valuable fishery fish. | ||
