    Description: In this study the physical properties of silver carp burger over a period of six months at a temperature of -18 ċ were studied using pectin. Indicators such as hardness texture,juiciness, flavor and overall acceptance of the product containing. The product were evaluated using qualified assessors، the microbial,chemical markers to evaluate the qualitative change such as peroxide treatments, total volatile nitrogen bases ، total count of bacteria and examined psychotropic of tests six months of treatments carried out on a monthly basis. The results indicate that the addition of pectin 0/3 percent of total admissions acceptance of burgers tissue was obtained and significant differences are. The chemical test results were also increased with storage time burger in refrigerators -18 degrees. Range of volatile nitrogen bases out of 15.2±1.2 at the time of 26/5±1.17 mg/100, the peroxide from 0.6±0.61 to 3/56±0.6 meq/kg of oxygen was. Thus despite a significant increase in indicators of physical Chemical and sensory evaluation of texture analysis. In the past six months storage period of -18 degrees, burger productive uses of pectin 0/3 percent of the limit between acceptable and will was.

    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.

    Description: Risks assessment of laboratories of National Fish Processing Research Center was done in 2014 and 2015 to determine the risk factors, potential risks and provide action plans to prevent the occurrence of any risks and increasing awareness of staff to safety issues. All laboratories: Chemistry, Microbiology, sensitive assessment and physical were visited and all factors were evaluated. The method for evaluation was with Failure Mode and Effects Analysis (FMEA) methods. The assessment process was designed and implemented in two phases, the first phase was the current situation of safety indexes, risks identification and distance to laboratory safety parameters included: working environment, physical factors, test methods and the human factors were done, then risk assessment and risk management of identified risks were followed by check list forms. The second phase was based on the findings, control measures and safety guidelines were done and provided. the highest risk score related to Microbiology laboratory with RPN 540 and then chemistry 360, because of the nature of sensory laboratory was not evaluated and There was no experiments in the physics laboratory and was ignored. After control measures, the risk number of laboratories decreased as follows: Microbiology to 18, chemistry to 12.
