    A study on environmental pollutants (pesticides, heavy metals & detergents) in surface water, underground water and wastewater of Mangol Dam basin (Mazandaran province) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: At the present study, the environmental pollutants such as organochlorine pesticides (OCPs), heavy metals (during three seasons) and surfactants (during four seasons) were done 2009 to 2010 that located in Mangol Dam with longitude and latitude 52° 22' 49" N and 43° 15' 43" E, respectively. The aims of this study were to determine the seasonal pollutants matters in water samples of under-groundwater and surface water in 12 stations and the results are as follow: The maximum residues fluctuations of OCPs were determined in between all water samples such as aldrin and endrin about 1.51 and 2.85 µg/l, respectively. The mean concentration of aldrin and endrin about 0.66 ± 0.59 and 0.71 ± 1.07 µg/l, respectively were determined. The maximum seasonal concentration of OCPs were detected in fall, winter and spring for such as endosulfan sulfate, γ-BHC, heptachlor, endrin aldehyde compounds about 2.85, 0.34, 0.14 and 0.14µg/l, respectively. The maximum seasonal percentage range of OCPs were detected in fall, winter and spring in water samples such as endosulfan sulfate, DDD and β-BHC were 42, 25 and 25 %, respectively. The maximum seasonal concentrations of Zn and Fe elements were detected in spring about 1.12 and 8.22 µg/l, respectively. Also for Hg in spring was determined about 17.2 mg/l. The mean concentration of Zn, Fe and Hg in water sampled were 0.23 ± 1.01 and 1.21 ± 2.00 µg/l, respectively and 4.65± 6.38 mg/l. The maximum seasonal percentage range of heavy metals were detected in fall, winter and spring in water samples such as Ni, Zn and Fe were 66, 83 and72%, respectively. The maximum seasonal concentrations of heavy metal were detected in Sorkhroud and Polechelave stations during fall, winter and spring for only Fe about 1.48, 3.3 and 8.22 µg/l, respectively. The maximum concentration of linear alkyl benzene sulfonate (LAS) in last month of summer was 971µg/l. The mean concentration of surfactant during fall, winter , spring and summer was 418.62 ± 52.16 µg/l. The maximum seasonal percentage range of surfactant uring fall, winter, spring and summer in all stations of sampling were 76, 76, 100 and 100 %, respectively.

    Survey of physico- chemical param eters in water within fish cage culture establishm ent (before fish breeding) in the Southern Caspian Sea (Mazandaran waters - Kelarabad) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was carried out in the Southern Caspian Sea region and on the coast of Mazandaran in the Clarabad region, which was considered as the location of marine cages. Sampling was carried out seasonally over a year. Sampling was done using a 48 hp boat. Sampling of surface depths of 10 and 20 meters in four seasons was carried out in spring, autumn and winter. Sampling from depths of surface, 10 and 20 meters in four seasons was carried out in spring, summer, autumn and winter. Samples taken from all lines were transferred to laboratories from different depths in plastic containers of 1 liter under Proper conditions. The purpose of this study was to investigate the physico-chemical factors of water including air and water temperature, salinity, transparency, dissolved oxygen, DO%, pH, EC, TN, DOP, DIN, DON, NO2 , NO3 , NH4 + , PO4 , and TP. The results showed that the surface water temperature in these three stations fluctuated from 11° C in the winter to 30° C in the summer. The lowest range of water temperature changes is 20 meters deep at 9.5° C. The average annual water transparency is estimated at 4.50 m. The range of pH changes from 8.13 to 8.78 in autumn. The maximum amount of dissolved oxygen per year in the surface layer was 10.37 mg /l, and the lowest was about 6.64 mg /l at a depth of 20 meters. Minimum concentration of nitrogen, including nitrite, nitrate and ammonium, was 0.26, 19.02 and 1.00 µg /l, and maximum was 3.7, 75.67 and 49.3, respectively. The maximum total nitrogen concentration in the winter season was at the East station and at least in the autumn and at the central station. Also, the concentration of nutrients (nitrogen and phosphorus) in addition to the increasing trend from the west to the east, and the amount of nutrients at the water level increases the designated stations. Mineral phosphorus concentration is highest in summer of 18.08 and the lowest in autumn is 6.15 µg /l. In this study, maximum total phosphorus concentration in spring was 44.45µg /l and at least 14.11µg /l in autumn.

    Description: Different studies on Litopenaeus vannamei (Boone, 1931) has performed in Iran, but less noted in water quality conditions. Water quality, in addition to creating optimal environment for the growth of vannamei shrimp, as well as cause the live food production and improve economic performance are produced. This study was conducted to evaluate the water quality environment vannamei shrimp in the south of Caspian Sea (Mazandaran province) and in the Caspian Ecology Research Center. The results showed that the enrichment of water out of the ponds, can provide favorable conditions for water quality in the culture of vannamei shrimp with different densities. As a result, Mazandaran province environmental conditions (particularly temperature and salinity of the Caspian Sea) has perfectly suited for optimal growth vannamei shrimp. Therefore, vannamei shrimp (PL12) achieved a final individual weight of 21.1gr in a period culture of 85-day with a density of 35 ind/m^2. Also, The nutrients and water quality parameters (Temperature: 27.4±1.79 ° C, Transparency: 10.7±1.2 cm, Salinity: 10.57±0.78 psu, pH: 8.42±0.38, Dissolved Oxygen 8.04±1.35 mg per liter) were within normal limits during the culture period.

    Description: Currently, different kinds of chemical fertilizer such as urea, nitrate, sulphate and ammonium phosphate–potash are using in fish ponds of carp (Hypophthalmychthysmolitrix, Hypophthalmychthysnobilis). Chemical fertilizers, especially phosphate fertilizers can cause environmental pollution. Therefore, the use of alternative one, particularly organic fertilizer (manure) can reduce environmental issues. This study is conducted to effects of liquid cow manure on abundance, biomass and community structure of phytoplankton, zooplankton, physico-chemical chractrestics and heavy metal of water in the warm water fish ponds. For this purpose, the effects of three different types' fertilizers have been searched on fish ponds water. The ponds number 1 and 3 treated by chemical fertilizer and liquid cow manure respectively. Both of the two fertilizers (liquid cow manure and chemical fertilizer) were used in the pond number 2. Results showed that acidity of liquied cow manure was low (pH=7-8), however the total hardness and alkalinity were high. Meanwhile, percent of nitrogen were more than percent of calsium and phosphorus liquid cow manure. The concentrations of Pb, Fe and Zn elements were higer than critical level but some of them such as Cd, Cr, and Hg were lower than detection limit. As a conclusion, biomass of phytoplankton, zooplankton and physico-chemical parameters in fertilized pond treated by liquid cow manure were more convinence than pond treated by chemical fertilizers.
