Limnologic study Sabalan runoff Dam for aquaculture fish cold water
Limnologicalstudyof SabalanrunoffDamfor aquaculturecold water fish was conducted in sixtimesat fourstationsfrom JulytoDecember2009.Averageminimumandmaximumparametersmeasuredindifferentstationswere included water temperature, dissolved Oxygen, total hardness, electrical conductivity, pH, BOD5, COD,TDS, NH4, NO2, NO3, PO4, TN, TP, SiO2, respectively (10/3 ± 9/5-14 ± 8/7° C), (9 ± 1/2-11/4 ±2/1 mg/liter), (367 ± 19/8-381 ± 17/8mg/liter), (0/95 ± 0/07-1/05 ± 0/07 mz/cm), (8/3 ± 0/1-8/4 ± 0/1), (3 / 3 ± 1/14-3/88 ± 0/71mg/ liter), (15/5 ± 3/1-16/3 ± 3 mg/liter), (0/48 ± 0/04-0/54 ± 0/06mg/ liter), (0/08 ± 0/02-0/13 ± 0/07 mg/liter), (0/004 ± 0/003- 0/05 ± 0/1 mg/ liter), (0/6 ± 0/2-0/64 ± 0/29 mg/ liter), (0/19 ± 0/07-0/22 ± 0/07 mg/ liter), (10/48 ± 0/6-10/98 ± 0/54mg/liter), (0/39 ± 0/11-0/44 ± 0/18 mg/liter), and(9/9 ±0/6-11/1 ± 1/4 mg/liter). Averageminimumandmaximumof water heavy metalswas included of Cd, Pb, Zn, Fe, Cuand Ni respectively was measured as ND(No Deliver), ND, ND- 0/242, ND- 1/075, ND- 0/018andND- 0/014inmg/ liter. Alsoamong the16organochlorinecompoundsmeasuredthehighestamount of was belonged totoxinHexachlorine Benzene (1/5 mg/ liter). The results of theanalysis ofwater quality parametersshowed that parametersexcept ofCOD, TDS, PO4, TP, Zn, Fe andwater temperature, otherparametersdo not haveany restrictions foraquaculturecold waterfishin therunoffDam. Based on data results it was noticed that there was temperature restriction up to November at downstream and station 2 showed less temperature fluctuation and more suitable condition compared to other stations. BOD5 value was within the allowable range for growing trout, in which station 2 somewhat with lower volatility of value had the most suitable BOD5 condition.In the present study, the amount of TDS in the study area was somewhat higher than the limitation and since TDS values increased with distance from the dam, therefore station 2 had somewhat better conditions for fish farming.In addition the amount of EC in the study area, indicating the inappropriateness of it for various activities in the fisheries.Although none of the stations in terms of the amount of phosphorus didn't show favorable conditions for rainbow trout fish propagation, it appears between the researches stations, station 2 had the most favorable terms.The results of this study (regardless of the unseen), it seems that in August and September; Zn had overestimated value for cold fish propagation. Recent study showed that among heavy metals, Fe in water, sediments and fish was over limitation value. Also, Fe value was measured of 1.08 at station 4, which showed over normal value for cold fish propagation. Therefore, station 2 at downstream seemed to have suitable cold fish propagation due to lower Fe value. On the based on the recent study, planktonic biological index did not endorse water quality for fish propagation. In this study, aquatic plant such as Potamogetonpectinatus and Pheragmitiesaustraliswas found at water of higher and somehow polluted organic matter. Probably, based on the results it was noticed that downstream water of dam was polluted to organic matter. At the recent study, resisted maroinvertebrates to organic matter (Chironomidae) was consisted noticeable frequency compared to other sensitive invertebrates to organic matter (EPT).Statistically, it can be expressed that probably organic pollution resulted to increase of resistance invertebrates and decreased of sensitive groups. In recent study, EPT/CHIR index was measured 0.6 in station 2 and 1.74 in station 4. This ration was less to many other mountain rivers. As ETP sensitive invertebrates has higher sensitive to other groups with the regards of environmental condition and pollution, unpredicted increase of Chironomidae compare to sensitive groups resulted of EPT/CHIR value which showed environmental stress. In this study, HFBI index was measured as 7.49 at station 2 and 7 in station4. Based on HFBI index, station 2 was classified as a high organic pollution and station 4 with noticeable organic pollution. At the recent study, station 2 was catch more fish to station4. For instance, Squaliuscephalus and Alburnoides bpinctatuswere catch in station 2 and were not found in station 4. As a whole, Biologicalindicators whichwas includedPlanktonBioindicator, EPT / CHIR. ,HilsenhoffBiologicalIndicator, diversityanddistribution ofaquaticplantsandfish, showed water situation inrunoffDamrich inorganic matter. Finally, thestudy areawasapprovedfor fish farmabout 50tons and needs managementarrangementswiththeincreasedproduction rate.
