  • 1. H. Nazari, R. Mosavi-nadoshan / International Journal of Engineering Research andApplications (IJERA) ISSN: 2248-9622 www.ijera.comVol. 3, Issue 3, May-Jun 2013, pp.384-387384 | P a g eHydrobiological Assessment Of Zoshk River, Mashhad CityH. Nazari and R. Mosavi-nadoshanIslamic Azad University, Nort Theran branch, Theran Iran,AbstractZoshk River is one of the major rivers ofMashhad city always filled with water .thepresent study is devoted to hydrobiological studyof Zoshk River in a one –year period , fromOctober 2006 to September 2007 , in four sitesthe origin or the river to the end of Shandizregion . In this study physical factors such aswater temperature , air temperature as well aschemical factors such as NO3 , PO4 , BOD5 andPH were measured . During the study periodconcentration of soluble Oxygen was always insaturated conditions with an average of 9.6 mg/Land the concentration of BOD5 was alwaysignorable with an average of 3.7 mg/L . Basedon the results , Zoshk River is a good placeaquaculture and raising Oncorhynchus mykiss.Keywords-: Zoshk River; aqua culture; BOD5; PH.I. INTRODUCTIONRivers are lotic or running waterenvironment that are usually habitats to an amazingdiversity of species with abundant specializedniches. They are also sources of water for drinking,cleaning, bathing, washing clothes, preparing andcooking food, gardening and even for irrigatingfarmlands. Moreover, they serve as source oflivelihood like fishing and in some areas, quarrying[1] .Zoshk River is one of the branches of theKashafrud. It flows from the northern slopes of theBinalud mountains towards the Northeast, Lengthof the river is 540 km . the purpose of this presentpaper is investigating of quality of water in 4various stations.II. MODEL DETAILSFour stations were established by using ofvarious factors such as maps with Scale 1:150000,taking into account water flow rate and substrategene of river and amount of Baetis populationchanges (finge 1). the Zoshk River were sampledbetween October 2006 and September 2007.Different Physico-Chemical parameters weremeasured like pH, temperature, dissolved oxygen(DO) , phosphates and nitrates. To sample BenthicMacro of flow waters , we had used a customarydevice named Sorbey . Then Obtained samples thatfixed with 4% formalin were investigated.Determination of Dissolved Oxygen (DO), pHand Temperature.In situ measurements of dissolved oxygen, pH andtemperature were conducted a portable DO meter,pH meter and thermometer , respectively in threereplications.Nitrate AnalysisTo measure nitrate , we used identifiers ofsodium chloride , concentrated sulfuric acid andsulfate acid Berosin . After the steps relevant, Thefinal solution absorbed was read at wavelength of 41nm . in comparison with the standard absorbedcurve of device, the nitrate concentration of watersamples was calculated [2] .Phosphates Analysis`Weve added 0.5 ml of compound solutionincluded ammonium molybdate, sulfuric acid,ascorbic acid potassium molybdate to 100 ml ofwater sample by using of scaled Cylinder . andimmediately Blend and We were to evaluate thelight fading coefficient in wavelength 885 nm after10 minutes . in comparison with the standardabsorbed curve of device, the Phosphateconcentration of water samples was calculated [3] .finge 1:The map of zoshk river ●shows thesampling sitesIII. RESULTSAccording to our results, the amount ofoxygen in all year levels is desirable The amountmaximum of dissolved oxygen was measured
