| Abstract | ||
| During planktonic exploration in the study of the construction of coldwater fish culture in Zayandehrood riversides during 2007-2008, it showed that the plankton of this river has a low frequency and diversity. Planktonic sampling was carried out at 7 stations and along the river. The plankton sampling method was designed to measure, Phytoplankton were collected for a liter of water directly , for Zooplankton samples 30 liter of water were filtered by 55 micron zooplankton net(Apstein net). Samples were preserved with formaldehyde at % 4 concentration for analyses in the laboratory. In phytoplankton study of this river, 4 phylum and 25 species have been identified. The most commonly observed species belong to Bacillariophyta, The most important of genus this phylum were Navicula, Cymbella and Nitzschia. Bacillariophyta accounts for 94.7% of the annual Phytoplankton frequency in this river. 6 Phyla and 29 genera were identified in zooplankton study, the most frequent of which was Protozoa and the most diversity was related to phylum Rotifera. The results of zooplankton study show Protozoan domination with %74.2 of zooplankton population (Ciliophora %51.8 and Rhizopoda %12.7) which has the most frequency. The most important genus of Rhizopoda was Difflugia, Arcella, and Centropyxis. establishment fish culture along the rivers was commonplace in world, so the development and revision of river fortunes is essential for proper exploitation of these water resources in aquaculture, while maintaining the health of the river ecosystem necessary . | ||
