    Aquaculture Potentials Investigation of Yamchi Dam Down Stream Areasin in Ardabil Province (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The research conducted for finding of aquaculture potential and appropriate areas of Yamchi dam downstream river and estimate of its production in 2010-2012. Yamchi dam is located at 25 kilometers of southwest of the Ardabil city. This research done by using of available information and data obtained from the monthly and seasonally sampling. After evaluating of Yamchi river potential and its marginal lands, suitable locations for aquaculture determinated and theirs production was calculated at each site. Totally, 3 areas selected for trout aquaculture and varius method suggested including race way, octagonal pond and semi-recircultaion. In the present condition of Yamchi river the amount of trout production is predicted at least 65 ton by race way to maximum 1750 ton by semirecircultaion method. Whiles, if 2 cubic meters of water from Yamchi dam outlet is provided to aquaculture, it will be predicted at least 580 ton by race way to maximum 4000 ton by semi-recircultaion method

    Identification, Biomass determination and seasonal changes trend of the dominant aquatic plants’ cover in Anzali wetland (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Aquatic plants play an important role in the aquatic ecosystems because of food production and habitats for fish, wildlife, and other aquatic organisms. In recent years, many parameters such as high the mass of nutrition, organic matter and pollution have had a significant effect on the variation of the biological population. In this study, the samples of aquatic plants were identified in 4 stations of Anzali Wetland ( West, Center, Sheijan and Siah kishim) and dominant species biomass were investigated. In this study, 21 plant species belonging to 17 Family of aquatic plants were identified. So, 540 samples were collected in the plot of 1 m2 in 15 stations by systematic random sampling. Species were identified and wet weight was determined. The physic-chemical parameters of water were measured based on standard methods. The relationship between plant coverage (Flura) and Physico-chemical characteristics of water was analyzed by using of PCA in Canaco 4 software. According to this study, the Potamogenaceae and Thyphaceae specified the highest population in 4 and 2 genera, respectively. Based on Rainier’s method, the results of aquatic species classification showed that the highest percentage of plants such as Cryptophyte ( 37.2 %), trophite (23.53%) and Halophite ( 39.38 %) were the main structure of the plant diversity due to climatic features in Anzali wetland. As well as to evaluate the plant Chorotype, plant elements of this area were extracted and compared by using of available resources. The wetland Crorologic group listed by Cosmopolitan ( 57.14%), multi-region (28.57%) Europe-Siberian and Mediterranean ( 7.14%) & Iranian-Turanian (7.14%). The result showed that the average of the total biomass of aquatic plants was 746 g/m2 in this area. The result also showed Ceratophyllum demersum, Nelumbium capsicum and, Trapa natans had the most effect on increasing and decreasing weight of the plant's biomasses in different seasons. The analyses of PCA showed that highest biomass wet weight because of the potential Ceratophyllum demersum for growth in the depths of the wetlands and high nutrient loads in this area.

    Limnological survay of Anzali wetland data during 1990-2003 by use of GIS system (2018)

    Publication Date: 2021-05-19
    Description: Anzali wetland at south west of Caspian located along of North West and southeast and with its unique feature were add on the Ramsar convention list in 1975. There were recorded a high rich of fauna and flora including 276 plant species, 23 reptiles and amphibians, 60 fishes, 26 mammals and 195 birds. Anzali wetland were encountered with numerous disorder with the eutrophication and the early dismissing. The first studies on Anzali wetland started by many international institutions in 1964. In this study the data of biotic and abiotic factors in Anzali wetland analyzed which belongs to different sites (15 to 38 stations) during 1991 to 2000 and were sampled seasonally or monthly in different years. The results showed the increasing trend of phytoplankton abundance from 7.9 to 66 million C./l. and the western part had the most abundant. The Cyanophyta had the most development than other 7 phylum observed in the area. In Anzali wetland identified 143 phytoplankton genus that 9 genus dominated in more than 80 % replicates and 7 genus had the abundance of more than 5 million cell/l. The Zooplankton abundant increased from 580 to 2200 ind./l. The Rotatoria had the most abundant followed by Copepoda. There was identified 104 zooplankton genus that 5 genus were dominated in more than 80 % replicates and 11 genus had the abundance of more than 30 ind./L. The chlorophyll a varied from 8.8 to 50.2 μg/l. and had a increasing trend after 1996, meanwhile it was measured higher than 25 μg/l in most of the stations. The results of benthic study showed that the Chironomidae and Tubificidae were observed more than other organisms which comprised 12.2 to 23.5% of total biomass of benthic organisms in studied period. The range of biomass was 1.1 to 7.8 g/m2. The ichthyologic survey showed presence of 60 species that 11 species were exotic. 28 species belong to freshwater, 17 species were anadromous and 8 species were resident in estuary. The highest and lowest fish catch were 640 and 288 ton in 1994 and 1999 respectively and it was about 500 ton at the end of period. The hydrochemical factors had the various fluctuation so that the nutrients parameters had a significant difference over studied period. Total nitrogen was varied from 0.78 to 1.41 mg/l and total phosphorus varied from 0.05 to 0.1 μg/l.. The oxygen dissolved amount was from 4.6 to 8.7. EC was between 3 to 5 ms/cm during September and October that indicated of Caspian water projection. According to geographic position of station, all biotic and abiotic data, were arranged. The data bank is used by Idrisi software to produce of necessary maps. Analysis of data showed that there must be a responsible department with a vast authority. Conservation and eutrophication prevention of Anzali wetland connect to special attention to catchment area and landuse management of the wetland. Also there is an urgent need for well-developed technologies and managements to reduce the organic pollution and its environmental impacts on the Anzali Lagoon.

    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Caspian trout is valuable, Commercial, anadromous and endemic fish species in the Caspian Sea so that, researchers attention have been focused on this species. At the moment, only pay attention to stocks rehabilitation that fisheries organization releases more than 300,000 fingerlings to the rivers ends to the Caspian Sea. Importance of this study consist (1) introducing a new species to the aquaculture system and (2) provide breeders in this research. we used from 2 treatments that consist with density of 10 kg/m^3 and 20 kg/m3 with 3 replication. Results showed, culture of Caspian trout is suitable with density 10 kg/m^3, so that weight gain, SGR and Daily growth mean are better than treatment 2(15-20 kg/m^3 )
