parameters of Rutilus firisii kutum Kamensky 1901 larva and compare with routine
condition according to hypothesis that use of Slurry, fertile organic compound, to increase
the efficiency of survivorship and growth of Rutilus firisii and in other hand adaptation
of natural food was performance.”
The object of this project is to compare growth of Rutilus firisii and in usual condition
and the condition of use Slurry The experiences performed in culture and propagation
center Dr. Yousefpour decent (Associan of Dr. Beheshti culture and propagation) in
Siahkal village, 32 Km far from southeast, in North of Iran. In this plan, three
different treatments and related these nine pools , in 1.7 hec area (in same condition)
were determined so that the density of storage was 1.7 million/hec larva.
In this research at first treatment m we use slurry as enrichment compound during larval
within a period of 13 days, and it used all the days of during larval in second treatment.
Then the result of this study compared to control treatment. The results have shown the
level of this study compared to control treatment. The results have shown the level of
survivorship in pools were nutrition by slurry was 1.7 million times or twice than pools
were nutrition with usual concentrate. In addition, growth coefficient such as daily
weight growing (DWG) index, daily length growth (DLG), specific growth ratio (SGR) were measured in this case. All of these parameters in slurry treatment were shown
noticeable enhancement in first treatment
Thereof in the first week there was significant difference (P<0.001) between the average
of length and weight in first week , and in the second week there was a significant
difference (P<0.05) between them
Effects of Zingiber officinale as Feed Additive on the Common Carp Body Composition
The present study was conducted to evaluate the use of ginger powder in diet of common carp, Cyprinus capio (27±3 gr). Different levels of the plant powder (0, 0.25.0.5, 1 and 2 gr / per 100gr food) were spread on commercial diet. The feed was offered by 8 weeks. Results showed that fish fed experimental diets had no significant difference (P>0.05) in amount of NFE, but have significant difference in protein, lipid, ash, moisture percent and kcal energy from different diet (p<0.05) while in kruskal-wallis test illustrated significant difference in amount of carbohydrate and body fiber (p<0.05). So, the best results in amount of protein, lipid, and energy shown in maximum dosage of ginger powder in carp commercial diet and low amount of them shown in control group. There were high amount of carbohydrate and low amount of fiber in control group. There was the lack of fiber in control group and upper level of ash in the third treatment. So, this study presents that; to be improving the body composition of common carp we use the herbal medicine like Ginger powder in their commercial diets

Effects of rainbow trout farming on water quality around the sea farms in the south of the Caspian Sea
The purpose of this study was to investigate the physical and chemical factors of seawater to determine the water quality index around two marine farms of rainbow trout in the south of the Caspian Sea. Each farm had four floating polyethylene cages with a final fish harvest of 60 tons. The water sampling was performed in January and March 2014 as well as May and August 2015 from around the cages (close: cage shade, 50 m and 100 m; distant: 1000 m) in three geographical directions: east, west, and south. The water quality parameters including pH, temperature, transparency, salinity, electrical conductivity (EC), total dissolved solids, dissolved oxygen, and nutrients (nitrogen and phosphorus compounds) were determined. The results of the analysis of variance of data at both farms showed that changes in physical and chemical parameters of water had only significant differences at the time of sampling (p < 0.05). The highest value of variance in the principal component analysis (PCA; 30.23% from 84.75%) was related to EC, temperature, salinity, total nitrogen, pH, and organic phosphorus. Iran Surface Water Quality Index (IRWQISC) at near and far distances from farms was determined to be moderate (40-55). The main reasons for this result can be attributed to the small-scale and short fish farming period along with the hydrological conditions of the region
First Nationwide Study of the Prevalence of the Metabolic Syndrome and Optimal Cutoff Points of Waist Circumference in the Middle East: The National Survey of Risk Factors for Noncommunicable Diseases of Iran
The survey of investigation about Mesopotamichthys sharpeyi projects in development program in Iranian Fisheries Research
Attention to the aquaculture capacity in inland water is needed to reach production of 262072 tons which was implicited in sixth economical and social development program of culture and production warmwater fishes industry. On of the most important aim of progressive management in fisheries program is native aquaculture activity with emphasis on Barbus fishes in Iran.Benni fish is one of the species of this genus despit of low relative growth rate, but is as a desire fishes in market. This fish not only has high fecondity and feed phytoplankton during the larval stages but also is very delicious for consumers. During the fifth economical and social development program there were so many projects have been done on aquaculture of this species but needs to analysis of all data which is important for successive future its aquaculture commercially. The precent analytical investigation base on three decades data, was done for completeing that gap including of analytical activities of researches were done, developmental access to fish aqu culture in six proficiency subjects , propagation and cultue, nutrition, genetic, health and disease biology, physiologt and determination of weak points. Then base on guideline studies on warmwater aquaculture and developmental road map, several suggestion for doing apply research were adopted
Standard of insurance procedures and risk assessment manual for cold water fish culture regarding management and natural disasters
The total production of Rainbow trout fish aquaculture in 2009 had been 72515 t which was significantly increased (91519 t) in 2010. Despite of increasing trout fish production during last decade, absence conformity between suitable cultural and proliferation district of this fish species and geographical one, faced this industry harmfully to natural disasters such as flood, overflow and so on, and mismanagement due to human injustices. Hence insurance and supporting concept of can be having a determinant role in efflorescence and increasing production of this fish. The aim of this project is performing an insurance policy based on risk analysis model in propagation and cultural phases of rainbow trout aquaculture, separately. In this study, pay attention to standards in trout fish aquaculture procedure and determination of critical parameters on, are the first research step and recognition of risk factors in different aquaculture phases due to natural disasters and mismanagement, from the brood stock maintenance till reach to 3-5 g fingerling and finally market size fishes, are the following research steps. After determination of proportion percentages of each parameters regarding to arise the risk, analysis risks and risk management were done for trout fish aquaculture. Three provinces, Fars, Mazandaran and Charmahal Bakhtiary as poles production of trout fish were chosen as delegates of the whole Iran and insurance ability of trout fish hatcheries and aquaculture farms were done. Trout aquaculture standardization were obtained, natural disasters and mismanagement affected on aquaculture activities were recognized (Chapters 1 and 3) and due to importance of health and disease of trout fish, mortality causes and audit signs of also determined and analyzed (Chapter 2) . In Chapter 4, trout farms degraded and fix and natural disasters for trout fish brood stock, propagation hatcheries and cultural farms were analyzed and accounted. Finally, premium and recompense were accounted for hatchery and farm separately
Responsible aquaculture: warm water fish preparation management and preparation of guidelines
Responsible aquaculture is a new concept in Iran but in some countries there are good historical performances. In fact this concept is as the spacial challenge for developing countries in order to improvement of aquaculturist livelihood. In bangladesh, near to 60% of the people, which the most of are villagers, live under the poor line. Developing the NGOs and their activities to reach the responsible aquaculture objectives were so effective, since this activity has been knew as profitable acuaculture and many international workshops, symposiums and conferences have been held in this regard all the world. In this project, a complex of parameters affected on preparing management of warmwater fish farms have been studied with using previous studies and experiments of different countries and executive guidelines of four modules prepared including: -Guidline of preparing of warmwater fish ponds -Guidline of water enrichment and using fertilization in warmwater fish ponds -Guidline of using aeration in warmwater fish ponds -Guidline of stocking method in warmwater fish pond

Comparison between shoulder strength ratio and shoulder internal to external rotation range of motion in Zurkhaneh athletes and non-athletes subjects
Introduction: Shoulder internal and external rotator muscles play a critical role to provide stability and mobility for glenohumeral joint, particularly in the overhead athletes. Musculoskeletal adaptation and some special side effects due these physical demands and movement patterns are very important for these athletes. The purpose of this study was to compare shoulder strength ratio with shoulder internal to external rotation range of motion (ROM) in zurkhaneh athletes and non-athletes subjects.
Materials and Methods: Twenty nine zurkhaneh athletes (mean age ± SD; 23.51 ± 2.04 years, sport history ± SD; 8.75 ± 4.47 years) and thirty non-athletes individuals (mean age ± SD; 24.8 ± 1.56) participated in this study. Data were collected through questionnaires and examination. Shoulder strength was measured by Hand-held dynamometer. Leighton flexometer was used to record ROM in both upper extremities internal and external rotations. Independent samples t-test was applied to analyze the data.
Results: There was a significant difference in internal/external rotation range of motion ratio among zurkhaneh athletes and non-athletes group (P ≥ 0.05). Also, the results of this study identified a prominent difference in internal/external rotation strength ratio between zurkhaneh athletes and non-athletes
group (P ≥ 0.001).
Conclusion: Repeated pattern of movements in the zurkhaneh sports for a long time causes muscle imbalance in strength and range of motion shoulder joint. It is known as a risk factor for shoulder injuries. Therefore; a design of corrective exercise and prevention strategies should be considered in training programs by athletic trainers and coaches.
