Roads intensify threat factors for wildlife and causes habitat degradation as use of corridors (underpass or overpass) are one of the most effective approaches to prevent these threats and problems. A highway crossing the Golestan National Park is threatening wildlife like leopard (Panthera pardus). Leopard is as endangered species in the IUCN Red List. The purpose of this paper is presenting the results of a study on locating suitable routes for overpass and underpass to reduce leopard road kill in Golestan National Park. For this, we applied the least cost path analysis. We created two friction surface layers, accumulated cost surface and start and end points as input data. We determined five paths to link habitat patches in the northern and southern parts of the Golestan National Park. The identified paths comparison and leopard road kill records along the highway were acceptable. The results of this study provided a means of concentrating on the most important locations for corridor construction for leaopard and its efficient management.

Wolf (Canis lupus) is the largest of the canidae in Iran, is considered opportunistic species with high compatibility and one of the main predator of ungulates in their habitats. It seems wolves prefer habitats which have a decent population of ungulates. Persian Gazelle (Gazella subgutturosa) is the largest herbivore in Iran's steppe plains. Habitats of Persian Gazelle in the west of Iran and in Qaraviz no hunting area adjacent to country of Iraqproportional to the dispersion mounds. In this investigation area boundary were considered equal to ultimate limit of distribution of gazelles During the summer and autumn seasons of 2013. Data of wolf attacks points was collected and it is divided into two sets, training data and test data. Then entered the model (Maxent) as geographic information system along with summer and autumn habitat suitability maps, Gazelles density and other 8 variables. The results of the score matrix and Jackknife analysis have characterize that distance from water sources and springs is the most important factor in habitat suitability of the summer and autumn and also possibility of the wolf spatial attacks. The results of the receiver operating characteristic (ROC) analysis and the area under the ROC curve (AUC) in the average runs, characterized which model has been successful in the prediction of attacks (AUC=0/949). Results show that areas with high-gradient, the high density of gazelles, near to the springs and watering places and north directions, have high-risk of Wolf attacks.

Conservation of large carnivore populations, particularly in areas with high level of conflict with local people is challenging. The grey wolf Canis lupus is an apex predator in Iran whose future is gloomy due to conflict with pastoralists across the country. However, our knowledge about its interaction with local peoples is extremely poor in Iran. The present investigation was carried out between October 2009 and May 2011 in Anguran Wildlife Refuge, northwestern Iran. Semi-structured questionnaire survey was performed in 100 households in order to evaluate local people's attitudes towards wolves and economic impact of wolf predation on livestock. In the meantime, scat analysis was performed to reconstruct main dietary components of the predator in the area. The majority of respondents (60%) considered wolf as the main enemy to their livestock; however, economic loss due to other non-predation factors accounted for more than 3.5 times of the depredation loss. Moreover, scat analysis indicated that wild boar and wild sheep compromise the main proportion of the wolves’ diet in the area. We concluded that wolf-human conflict is not currently serious in the area, but management implications should be considered to mitigate the present level of livestock loss due to wolves.

Investigation of the ecological characteristics of wildlife species and determination of their habitat suitability is one of the main goals for wildlife management and protection strategies. In this study, the autumn and winter habitat suitability of Roe Deer was investigated in Golestan National Park. Golestan National Park is one of the suitable habitats for Roe Deer (Capreolus capreolus). For habitat suitability modeling, the Ecological Niche Factor Analysis (ENFA) method was used. Ecogeographic factors were used as independent variables including altitude, slope, aspect, Normalized Difference Vegetation Index (NDVI), distances from roads, guard stations, villages, springs and rivers. Our result with 95 % of significance level showed that the best habitat for Roe Deer in autumn was in average altitudes 1009 m a.s.l., slope of 27%, south aspect, and distances of 1062 m far from the roads, 894 m from the rivers, 1019 m from the springs, 3216 m from the guard stations and 7385 m from the villages. In winter the altitudes 990 m a.s.l., slope of 23%, aspect of south, and distances of 1144 m away from the roads, 775 m from the rivers, 1097 m from the springs, 3083 m from the guard stations and 7172 m from the villages were preferred by Roe Deer. Subsequently these results showed this species has a narrow niche and a tendency to occupy marginal habitats.

Deficiency of uridine monophosphate synthase (DUMPs) is an autosomal recessive genetic disease which caused by a mutation in UMPs gene at codon 405 from exon 5 of bovine chromosome no 1. This mutation leads to a premature stop codon, which subsequently produces a functionally impaired enzyme. It is possible to detect recessive genes of carriers using molecular techniques to prevent DUMPs distribution in population which is time- saving and cost-effective with high accuracy. In this study, blood samples were collected from 100 Iranian Holstein cows and 100 Guilan native cows from Guilan province, Iran. Genomic DNA was extracted from all blood sample using optimized salting out method. Specific primers were applied to amplify a 108 bp fragment from exon 5 in UMPs gene. In order to identify carrier animals, a PCR-RFLP assay was carried out and PCR products were digested by AvaI restriction enzyme. All samples indicated dominant homozygous genotype and no heterozygosis were observed which maybe explained due to high selection pressure and international reduction of defective gene pool. In view of the fact that there is re-occurrence risk of heritable defects, therefore, widespread screening programs to detect genetic disorders seem to be necessary.

At this experiment was studied information of income and costs of 20 crossbred herds at Guilan province included Lahijan (7 herds), Amlesh (1 herd), Rezvanshahr (3 herds) and Masal (9 herds) cities. The equations were estimated for economic cofficients of milk production, fat percentage, protein percentage and herd life in maximum profit interest and and minimum cost price interest. For crossbred cow equations for economic cofficients of milk production (Rial/kg/cow/year), fat percentage (Rial/cow/year), protein percentage (Rial/cow/year) and herd life (Rial/day/cow/year) in maximum profit interest were (739, -60261, -30672 and 28), and minimum cost price interest (-0.24, 19.89, 10.12 and -0.01), Respectively. In native cows, the economic weights of these traits in maximum profit interest were 232, -6242, -3177 and 454 and minimum cost price interest -0.11, 3.2, 1.6 and -0.23. Economic weights of fat percentage and protein percentage were negative in minimum cost price interest and positive in maximum profit one. In both interest, economic weights of milk production and herd life had more importance than others. The relative economic weights of the traits were equal in both interests. The relative economic weight of herd life (to milk production) was positive in most cities so that increase in economic efficiency of production system for this trait was higher than others in the same direction to milk production.

Wetlands as complex ecosystems are under threat, destruction and degradation and researching on wetlands are a critical part of management and conservation actions. The Ramsar Convention is an international treaty on wetlands for conservation in the entire world that emphasizes wise use of wetlands and their resources to maintain and protect waterfowl habitats. The aim of this study is to evaluate the birds criteria of Aq Qaleh wetland to introduce to the Ramsar Convention in the north west of Iran. The data that were analyzed were obtained during field work in 2010-2013. Result show that the Aq Qaleh wetland has condition according to 2, 3, and 4 criteria of the Ramsar Convention. 93 species of the bird of Iran have been recorded, and 26 species of these birds have international and national cooperation for protection. 21 threatened or endangered species, 15 species of 1, 2, and 3 appendices of the CITES treaty, and 4 species of the IUCN Red List have been identified. Result of birds counting in the wetland illustrate that more than 20000 birds were been in the Aq Qaleh wetland during summer of 2013. Our data suggest that the Aq Qaleh have criteria of the Ramsar Convention, thus with studying other criteria, the Aq Qaleh and Suldoze wetlands together could be introduce to the Ramsar Convention to improve its conservation situation.

The aim of the present study was to perform a polymorphism evaluation of the gene 5 area of IGF-I in order to see whether there is any relationship between the gene and the features of quail’s carcass quality including the PH, the color of meat, the amount of water and fat stored inside the muscles of the Japanese quail. To this end, a total of 100 Japanese quails were reared under similar conditions; and then having been slaughtered at the age of 5 weeks, the carcass quality traits were measured and recorded. Moreover, before slaughtering was done, the blood of the sample birds was tested and the DNA was extracted using a diatom kit. Then, using PCR-RFLP method and the sectorial Enzyme PST-I, the segment no. 621 of the base pair was cut from this part of DNA to be multiplied. In general, having studied the quails, three genotypes of AA, AB and BB were acquired with the frequencies of 41, 35 and 24 percents, respectively. The allele frequencies of A and B were 58.5 and 41.5 percents, respectively. Investigating Hardy Wineberg’s equilibrium with the use of Chi-square test showed that the analyzed sample population is not at equilibrium at its true gene position. The Phenotypic analysis showed that there is a significant relationship between the genotypes of the gene IGF-I at its specified position and the lipid traits inside the muscle. Based on the results of the study, the conclusion is that the gene IGF-I can be used as the candidate gene for carcass quality traits in programs to amend and modify the species of the Japanese quail.

Currently the growth and immune stimulants commonly were used in aquaculture. These compounds have beneficial effect but there is not any study on their side effects in fish. So, the goal of this study was to evaluate in vitro effects of ethanol extract of propolis, β-glucan and levamisole on CHSE-214 Cell line. The live cells of CHSE cell line was prepared from Pasture institute and cultured in RPMI supplemented with bovine fetal serum, penicillin and streptomycin at 37 °C and 5% of CO2. Propolis samples were collected from West Azarbaijan honey bee, Apis mellifera carnica, and alcoholic extract was prepared. In this study different concentrations of these compounds (500, 1000, 2000 and 4000 µg/ml) at 24, 48 and 72 hours were assay with MTT as a colorimetric method. Finally, statistic analysis of data was done with one way analysis of variance and Tukey’s. Results showed that significantly ethanol extract of propolis has cytotoxicity properties at all different concentrations (P<0.05); the lower effect was record at 500 µg/ml (8.01± 1.01 percent) after 24 h and highest cytotoxicity effect was seen at 4000 µg/ml (100%) at 72 h. Also results showed that levamisole significantly (P<0.05) has cytotoxicity property on CHSE-214 cell line. Levamisole at 500 µg/ml concentrations has not inhibitory effect on CHSE-214 after 24 h, but the higher cytotoxicity was seen at 4000 µg/ml (20.11±1 percent) after 72 h. Beta glucan has not cytotoxicity effects on CHSE cell line at 500 µg/ml in all of time periods, the higher cytotoxicity effects was seen at 4000 µg/ml (5.06 ± 1.6 percentage) after 72 h. It should be concluded that cytotoxicity of these compounds are related to concentration and time. On the other hand, each agent could induce cytotoxicity in CHSE-214 based on concentration and it is different between these compounds. The results of this study showed that beta glucan, levamisole and lactoferrin have minimal effects but ethanol extract of propolis could cytotoxic at higher concentrations.

Infectious diseases are major economic losses in fish production facilities. Among the etiological agents of bacterial fish disease, the Aeromonas hydrophila is considered an important pathogen causing primary infection in wounds or the secondary problem following stress from temperature change, handling, or poor water quality. In the present study, six strains of Aeromonas hydrophila isolated from ten fish farms in diseased carp, West Azarbaijan province were characterized and compared with an American type strain by various methods including biochemical and physiological tests, PCR, antibiotic resistance profile and enterotoxin gene. Results showed that any differences were not seen between isolated strains and standard based on phenotypic and genetic properties. Antibiotic susceptibility test revealed that six strains of isolated Aeromonas hydrophila had different antibiogram profile, also higher and lower resistance was seen for enrofloxacin and sulfamethoxasole, respectively. It’s concluded that isolated Aeromonas hydrophila from carp in West Azarbaijan could produce enterotoxin and has antibiotic resistance genes.

An important tool in the study of the physiological state of an organism is the blood. The present study aimed to determine and record the variants between plasma and serum biochemical parameters in Great sturgeon (Huso huso), Persian sturgeon (Acipenser persicus) and Caspian roach (Rutilus rutilus caspicus) was performed. To achieve this goal, sturgeon and Caspian roach weighted average 3-5 and 2-3 g, were provided from Shahid Marjani Proliferation and Culture Center for Sturgeon Fish and Sijwal (Golestan province) and were kept in Research Center of Agriculture and natural Resources, Gorgan University. All of the experimental factors during the growing period (water temperature: 23 C˚, pH 7/5 and DO: 7/9; Fish were fed 2 times a day with commercial food) were the same for tanks. To examine the blood biochemical factors of serum and plasma (aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase (CPK), albumin, total protein and glucose), blood samples were collected and blood biochemical parameters was performed according to standard methods. There were no significant differences in the values obtained from the study of alanine aminotransferase (ALT), creatine phosphokinase (CPK), and albumin of all three species (Great sturgeon, Persian sturgeon and Caspian roach) (P≥ 0.05). Plasma albumin levels were lower than serum plasma in all three species, whereas plasma ALT levels despite the lack of significant difference (P≥ 0.05) in all three species were more than serum ALT. Serum and plasma glucose levels showed significant differences (P≤ 0.05) which in all samples, blood plasma glucose levels were higher than serum glucose levels. The AST factors in all three species obtained values from plasma were greater than those obtained from serum. Serum total protein was greater than total plasma protein obtained in all three species and also the differences in roach was significantly higher than plasma total protein (P≤0.05). Since the observed differences between some factors of serum and plasma in the present study, seems due to the greater similarity of blood plasma to natural blood status, the use of plasma is preferred to study in these three species.

This study was conducted in order to determine the effectiveness of canola meal cake replacement with fish meal on growth indices, body composition and food price of juvenile oriental river prawn. The experiment was performed based on completely randomized designs in 5 treatments with 3 replications of different substitution levels 0 (control diet), 25%, 50%, 75%, and 100 %. Four hundred and fifty prawns with average weight of 1.00 ± 0.12 g after two weeks of adaptation were feed with experimental meal for eight weeks. Growth indexes including average weight gain (WG) specific growth rate (SGR), food conversion ratio (FCR), protein efficiency ratio (PER), survival rate (SR) and body composition including moisture, protein, fat and ash were evaluated. The results of this experiment shows that the substitution of canola meal cake up to 50% with fish meal has positive effect on growth performances (p>0.05). However with further increasing canola meal cake in Treatments 75 and 100% the growth performances had shown unimproved and there were statistically significant with other treatments (p<0.05). Meanwhile no significant difference (p>0.05) were observed in body composition (protein, fat and ash); Only moisture of the body in Treatments 75 and 100% showed a significant increase (p<0.05). It can be concluded that upto 50% canola meal cake replacement with fish meal had reliable performance on growth of juvenile prawn and also resulted to decrease food price in this exprement.

The results showed that larvae of treatments 1&3 grew faster than treatment 2. Also , the same treatment produced heavier larvae than treatments 1 and 3 ( p<0.05). The highest survival rate belonged to T1 (90%) and the lowest to T2(67%). General abnormalities such as unbalanced swimming , skin injuries , anorexia, exophtalemei, Fin rot and deformations were observed as 50, 67 and 55 fishes per T1 , T2 and T3, respectively. Final results showed that there is the potential of SELCO enrichment oils production similar to foreign ones by interior potential.

The survey was carried out at the Zahak reproduction center on 11 mature males of Schizothorax zarudnyi at 2013. Each male, was injected by Oviprime hormone 3 times in 7 day interval. Sperm was stripped after each injection but no sperm was not obtained at the third stage. Spermatology parameters were measured in the first and second stage. The results showed that average duration of sperm motility was (45.09 ± 7.73) in the first stage of stripped sperm sampling and (52.84 ±5.20) in the second stage that the difference was not significant (p>0.05). The percentage of motile spermatozoa was (57.18 ±11.29) and (72.4 ±9.73) in the first and second stage respectively that the difference was not significant (p>0.05). According to the results of this study, the volume of sperm was higher in the first stage of sampling compared with the second one that this difference was not significant (p>0.05). The average of sperm density was higher in the second stage (0.8±0.10) compared with the first one (0.7±0.84) that the difference was not significant (p>0.05). The percentage of spermatocrit was obtained (35 ±7.16 and 33.55 ±2.91) and pH was (8.03 ± 0.12 and 7.78 ± 0.27) in the first and second stages respectively that there is a significant difference (p<0.05). The results showed that adjusting appropriate intervals for repetitive sperm stripping depending on the fish species in hatchery can be an effective technique in reproduction centers.

A comparative study was conducted on concentration of heavy metals Hg, Cd and Pb in the muscle and of Otolithes ruber in Boshehr and Bandar-e-Emam Khomeini Sea Ports in Iran from Persian Gulf. In this study used 42 samples of Otolithes ruber from Sea Ports. Metals were extracted from the tissues using wet digestion method and concentrations of the heavy metals were measured by Atomic Absorption Spectrophotometer. Analyses of the datas were done by helping of the SPSS17 software and analyse of the t-test. Concentration of Cd and Pb in the muscle of Otolithes ruber in Boshehr and Bandar-e-Emam Khomeini Sea Ports significant difference between (P<0.05), but level of Hg no significant difference between them (P>0.05). Metals of Hg, Cd and Pb in the muscles of Otolithes ruber from Bandar-e-Emam Khomeini were 0.04±0.008, 0.28±0.035 and 0.44±0.044 mgKg -1 wet weight. The results showed Concentration of Cd and Pb higher than in the muscle of Otolithes ruber from Bandar-e-Emam Khomeini Sea Port. Concentration of Hg and Pb in the muscle of Otolithes ruber was lower than comparison of WHO, MAFF, NHMRC, but Concentration of Cd higher than comparison of WHO, MAFF, NHMRC.
