The aim of this study was to determine the effects of Progesterone and Melatonin hormones on ovulation synchronization and improvement of pregnancy rate of Zandi ewes. In this study out of breeding season, 156 ewes were selected and divided into four groups. The first group (control) received no hormone injections. On ear of second group (Melatonin) were implanted a piece of Regulin contained Melatonin hormone and after 35 days, the rams released into the ewes. The ewes of third group (Progesterone) were received cidr for 12 days and 600 IU eCG intramuscularly and 48 hours after cidr removal the rams were released into the ewes. The fourth group (Melatonin and Progesterone) at first received a piece of Regulin and after 22 days received 600 IU eCG intramuscularly and 48 hours after cidr removal the rams were released into the ewes. Reproductive parameters including parity rate, lambing rate, twinning rate, litter size, weight and number of lambs were investigated. The results of this study showed that using of cidr and eCG could improve reproductive parameters compared the other groups (P<0.05).

Age structure and growth of the Caspian sand goby (Neogobius fluviatilis pallasi) in two populations from ZarrinGol River and Gomishan lagoon was studied with monthly sampling from March 2009 through June 2010. 320 fish from ZarrinGol River and 263 fish from Gomishan lagoon were caught. Male: female ratio was 1male: 3.4 female in ZarrinGol River. No significant differences were observed between abundance of male and female in Gomishan lagoon (P>0.05). In ZarrinGol river males were divided into 3 age classes of 0+ to 2+ and females into 4 age classes of 0+ -3+. In Gomishan lagoon both males and females were categorized in 3 age classes of 0+ to 2+. Age class 1+ was the most abundant class of fish in both sexes and populations. Mean total length (TL) of males and females in ZarrinGol River were 7.5 ± 2 and 8.2 ± 1.7 and 9.7 ± 1.1 and 8.2 ± 1.4 in Gomishan lagoon respectively. Growth pattern in ZarrinGol River was positive alometric for both sexes and isometric in Gomishan lagoon. Condition factor varied in both populations in different months and age classes. Comparison of condition factor for both sexes in two populations showed no significant differences in age class 0+ while there were such differences in age classes of 1+ and 2+. Values of the condition factor were higher in ZarrinGol population.

In this study, five plant communities were selected to study on the effect of disturbances of wild boar (sus scrfa) on total organic and particulate organic carbon in rangeland communities, i.e. Festucaovina, Bromus tomentellus, Alyssum minus- Astragalus sp., Trifolium repens-Poa pratensis and Chenopodium foliosum. In each community, one disturbed patch was selected and 3 1*1m plots were established in and out of each patch. Soil samples were collected from each plot. Total organic carbon (TOC) and particulate organic carbon (POC) were measured in the laboratory. The results showed that the effect of disturbance, plant community and the interactions on POC and TOC were significant. The highest of POC (3.33%) and TOC (4.69%) were observed in without disturbance (out the patches). The highest TOC was related to F. ovina community (4.58%) and the highest POC was related to C. foliosum community (4.17%). The lowest of the two soil characteristics was related to the B. tomentellus community (4.32% and 1.98% respectively). The interaction effects of disturbance and community on TOC and POC was also significant. The highest value of TOC was related to F. ovina outside the patches (4.86%) while the lowest value was related to B. tomentellus in inside the patches (3.92%). The highest value of POC was related to C. foliosum outside the patches (3.47%) while the lowest value was related to B. tomentellus in inside the patches (1.48%).

Fish epidermis contains alarm mucous cells which they react to environmental stressful factors, diseases and damages to skin. For histometrical and histocheical studies of these cells, at least 10 mature male and female silvercarpwere selected and 5 mm thickness samples were taken from different parts of skin including head, dorsal, ventral and tail. 5-6µ sections were made using paraffin embedding methods, and stained by general staining of H&E histochemical staining including; PAS and alcian blue (AB) with PH 1 and 2.5. Numbers of alarm cells were counted in 100µ length of epidermis in each region. The results showed that there are voluminous and ellipsoid cells called alarm mucous cells in different regions of silver carp epidermis. These cells have positive reaction to AB staining in PH 1 and 2.5 which it showing the acidic and sulfated property of mucous secretion of these cells. The skin of silver carp fish can divided basis to alarm cells distribution in different parts of epidermis (head , dorsal regions, ventral regions and tail); in mature male fish: The maximum and minimum number of alarm cells in 100µ length of epidermis are in ventral (5.40±1.26) and tail (0.92±0.19) skin respectively but in mature female fish: The maximum and minimum were seen in head (6.06±1.99) and tail (0.97±0.44) skin respectively.

Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system. The aim of this study was to determine the effects of biofloc technology in intensive culture of common carp fingerlings. Two groups of fingerlings (1-3 and 16-22g) were cultured in 45L tanks for 21 days. For each group, three following feeding treatments were assigned: 50% commercial diet (CD) + biofloc products, 75% CD + biofloc products and 100% CD as a control. Growth performances and physico-chemical parameters of water were measured and the results indicated that the fish fed with 50% CD + biofloc products show high percent weight gain than other treatments in first group (P > 0.05). But no significant difference was observed in case of growth performances in second group despite of decreasing in feed intake in bioflocs treatments. Also the results showed that application of biofloc system in intensive carp culture decrease concentration of ammonia, nitrite and nitrate despite of no water exchange (1% daily) in these treatments whiles water was exchanged at a rate approximately every 10 min in control. The results suggest biofloc technology seems to be efficient for intensive farming of common carp.

We identified birds and compared the diversity of birds between different habitats in Naqadeh, North Western Iran. Diversity and number of birds were monitored in four main habitats including semi-arid steppes, wetlands, agriculture and high mountains habitats from July 2010 to June 2012. Different habitats were also compared in terms of Species Diversity indices to evaluate relative importance of each habitat for birds. Overall 140 bird species were identified in the study areas, 53% of them were terrestrial and 47% depended on aquatic habitats. Among identified birds, 31 species have national/international conservation concerns indicating the importance of the study areas for threatened species. Among birds identified, 66 species (47.1%) were breeding birds including summer visitor or resident species among them was. Bittern (Botaurus stellaris) as the first breeding record for this province. The highest values of Simpson and Shanon-Wiener were found in semi-arid steppes (0.934 and 4.208) and wetland (0.872 and 3.457) respectively, both on them occurring in summer season. By contrast, the highest values of evenness indices of Camargo and Simpson were found in winter in agriculture (0.857 and 0.943) and high mountains (0.667 and 0.701) areas. The highest similarity coefficient (Jaccard index) was 0.685 and was found to be between semi-arid steppes and agricultural habitats. Not surprisingly, aquatic habitats supported the highest number of birds reaching a maximum of 10300 (75.1%). Present study implies that habitats around Naqadeh are important for bird fauna and further investigations as well as conversation measured should be undertaken to protect habitats and birds especially in semi-arid steppes.

In this study, effects of Benzo (a) pyrene (BaP) exposure on the levels of neurotransmitters in the different regions of brain and plasma levels of cortisol in the Yellowfin Seabream (Acanthopagrus latus) were examined. In the first protocol for assessing the acute stress responses, BaP was injected to a group of fish (50mg/kg BaP in 2µl/g per body weight). The control group for this procedure was injected with oil (2µl/g) per body weight. A group of fish was not injected to assess the basic levels of respective variables. Blood and brain samples from different groups collected 3 hours after injection. To study the long-term a group of fish was implanted with 50mg/kg BaP in 10µl/g coconut oil in respect to the body weight. As the previous protocol a control group was implanted with the same amount of oil without the BaP. Samples were collected from both implanted groups (treatment and control) after 72 hours. In the collected samples, plasma levels of cortisol and contain neurotransmitter in deferens region were assayed.
Plasma levels of cortisol in Yellowfin Seabream increased and contain neurotransmitter altered during both short term and long term exposure to the BaP. According to the results, BaP exposure may affect the synthesis, storage, uptake/release and degradation of the neurotransmitters in different regions of the brain, specially the pituitary gland. Serotonin showed more distinct responses under the BaP exposure stress than the other monoamines.

This study was done at a 42-day period. One hundred and fifteen male broiler chicks from Ross 308 commercial strain were used as a Randomized Complete Block Design with 5 treatments, 3 replicates and 10 pieces per replicate. The experimental groups were included controls, carrot pulp (50 g/kg diet) tomato pomace (50 g/kg diet), crab (50 g/kg diet) and shrimp waste (50 g/kg diet). To perform for colorimetric tests of broiler skin and meat 2–birds at day 42 randomly weighted and killed and a piece of the breast with skin was removed and after 24 hours of freezing, L*(brightness), a*(redness) and b*(yellowness) parameters were evaluated by Minolta CR-400 colorimetric device. In the Colorimetric Results showed that experimental groups only affected the brightness of the skin, so that pigment sources resulted in darker skin (p<0.01). APS resulted in darker meat significantly (p<0.01). Animal pigment sources APS also caused yellower meat rather than control diet, significantly (p<0.05) but no significant changes were observed in red meat color and the red color was normal in all groups. This experiment showed that the pigment sources can effect meat and skin color in broiler.

In this study, some of reproductive biological characters and gonadal development stages of ovarian tissue in 108 pieces of palaemon elegans shrimp, in the Gomishan wetland were reviewed during the end of December 1389 to June 1390. For this purpose, tissue sections were prepared from middle substances of the ovary of female shrimp monthly. Minimum and maximum of absolute fecundity ranged from 300 pcs and 2686 pcs. With increasing body size, the absolute fecundity of them increases and maximum of length range were 35-45 millimeters. Maximum redundancy of gonads in step 4 and step 5 was observed in April to June and in the final stage of egg development, egg volume reaches. to an average of 0.725 millimeters. It seems that fecundity of elegance shrimp in Gomishan wetland is much higher than other reported areas.

In this study pollution emissions of two Rainbow Trout farms situated on Khochireh and Hasanjoun branch of Shahroud River in Taleghan Dam basin was studied, using Hilsenhoff Rapid Bioassessment Family Biological Index (HFBI). Results of the Biological Index were comprised with Physical, Chemical and Contaminant results of affected rivers. Results showed that BOD5 in both branches were more than Shahroud River as a main branch but the farms didn’t have significant effect on organic matter increasing load (p>0.05). The effect of the farms on rivers pH were not significant (p>0.05). TSS in Hasanjoun River was more than Khochireh River (p<0.05) and Khochireh River had less phosphorus contaminant than Hasanjoun River (p<0.05). As a result, the load of organic contaminant in Hasanjoun was more than Khochireh branch (p<0.05). Changes in macrobenthos communities showed that the dominant families were Choronomidae (Diptera order) with 11.6 mean numbers in m2 and Elmidae (Coeloptera order) with 10.0 mean numbers in m2 in the study area. HFBI results based on macrobenthos diversity and density in sampling time showed that presence of Rainbow Trout farm in Khochire caused decreasing in river quality as little as one degree from “Moderate” in station1 to “Fairly poor” in station2. But this fish farm has not effect on Shahroud river main branch, based on no changing in HFBI results on stations3 and 4. The quality of Hasanjoun branch at fish farm upstream was “Bad” because of the presence of population centers in this area. Assimilative capacity of the river cause better condition in water quality at fish farm downstream in this branch as “Moderate” condition. Shahroud river at this area had “Very good” condition on station7 (upstream of Hasanjoun branch in Shahroud) and “Bad” condition on station8 (Downstream of Hasanjoun branch in Shahroud) that is shown the effects of organic pollutants entering from Hasanjoun branch to the Shahroud main branch. Results of physicochemical and biological comparison showed that in the sampling time, the fish farms had not impacts on Shahroud main river branch because of high water volume of this river.

The forests and grasslands of Dez and Karkhe National Park and Protected area are considered as the last habitat for Persian Fallow Deer (Dama dama mesopotamica). In this research the trend of habitat change for was studied in two separate time periods of 1973-1989 and 1989-2007 by interpretation of data gathered from MSS 1973, TM 1989 and LISSIII 2007 Two unsupervised and supervised classification methods were used, Initially the maps of five cover and land-use classification including: settlements; agriculture; forest; degraded forest, and water classification were prepared Then, the accuracy classification was assessed, using Cross Tabulation method. The results indicate that in the total time of study the forest cover reduced 35% and degraded forest increased by 48%, from which 23% reduction in forest cover and 32% increase in degraded forest happened in the second period of study. In the total period of study 25% of forest cover converted to degraded forest and another 10% along with 20% degraded forest converted to agricultural lands. Therefore the vast habitat change and reduction of forest cover can be considered as one of the important factor resulted in rapid population reduction of Fallow Deer, which caused no sign of species presence to be recorded in the region for the past decade.

Pomfret is one of the valuable and economic fishes in the Persian Gulf. According to observations and reports in the last 10 years, amount of fishing and it’s average size in the fishermen net is strongly decreased. The problems in it’s artificial reproduction, make impossible the restoration by reproduction way. For this reason accurate evaluation of population and then store management according to principles of population dynamic and it’s biology in the stable exploitation is necessary order. For this purpose performed extensive study between 2007 – 2013 years, that in this section is accounted growth coefficient, natural death amount, total death amount, fishing coefficient amount and then exploitation coefficient for evaluation; has been studied sexual testis and fishes puberty stages for store management. Growth coefficient is accounted during study 0.4, and after accounting total death, natural death and fishing coefficient, exploitation coefficient amount is 0.1296 that shows store reduction and critical status of population. The fish has a long spawning period from May to November (p<0.001). And the greatest sexual activity is in the female fishes with standard length 25.5cm and in the male fishes with standard length 21.5 cm (p<0.01).

Phylogeography studies usually represent the importance of historical processes in shaping of current geographical distribution of species and genes. The main purpose of this paper is investigating the genetic distance as well geographical distance of the Yazd province based on the mitochondrial data. In this study cytochrome b gene of mitochondrial genome from Ovis vignei and Ovis orientalis stool and tissue were examined for the association between haplotype, the haplotype genetic distance and geographical distribution. 9 haplotype of 30 sequences attained from Wild Sheep in Yazd province. Siahkooh Protected Area, Kalmand-Bahadoran Protected Area and Shirkooh No Hunting Area have got a common haplotype that represents extensive distribution of this haplotype than others in Yazd province. Calculated matrix of genetic distances demonstrates the greatest genetic distance (0.272) related to Wild Sheep in Buruieh Wildlife Refuge. The highest number of polymorphisms between the haplotype belongs to the Buruieh Wildlife Refuge by the 15 polymorphisms. Environmental event such as expansion of the Zagros Mountain in the south of province of Yazd is one of the important reasons for the distribution of Urial and Armenia Wild Sheep in Yazd province. Moreover, the lack of genetic exchange between Wild Sheep of northern and center of Yazd and Buruieh Wildlife Refuge is affected by extent plains in these regions.

A comparative investigation between growths of Gladius with some morphometric measurements of Uroteuthis duvaucelii was carried out within two water body of the Persian Gulf and Oman Sea in 2011. A total of 213 specimens were collected and 16 parameters were measured of which amongst them, 5 parameters of length and width of mantle, length and width of fin and Gladius width showed significant relationship with length of Gladius. There was no significant differences between Gladius of the Persian Gulf and Oman Sea but it is noteworthy to be mentioned that males and females have difference in shape, namely the width of Gladius in females are 1.32 times bigger than males. The Mantle length-Weight relationship showed an allometric growth (b=2.83, r2=0.97 in The Oman Sea and b=2.13, r2=0.84 in The Persian Gulf). A high significant correlation was determined between growth of Gladius with length of mantle both in the Persian Gulf and Oman Sea with estimated r=0.989 and 0.867, respectively.

To compare physical, chemical and biological indices of primary productions on the coast of Bandar-e Anzali, water column in the depths of 2, 5 and 10 meters was sampled. The physical index of primary productions by using the Secchi disc Was calculated, chemical index by measuring the density of nutrients in water and biological index by determining the density of Chlorophyll a in phytoplankton’s were calculated. The maximum clearance was 300 centimeters in spring and the average maximum density of total Phosphorus and total Nitrogen in water column was in spring and respectively 0.061 and 0.831 milligram per Liter (p<0.05). The maximum density of Chlorophyll a was in summer, 6.4 microgram per cubic meter. The results show that among these indices, it is better to use physical and biological indices. Both indices statistically have reversed correlation (p<0.05). Through comparison of information with qualitative water class tables, water of Caspian Sea can be located in Mesotroph water class from the density of Chlorophyll a point of view according to the amount of summer vision depth by Secchi disc and at the beginning of Eutroph water class from the point of view of total Phosphorus and total Nitrogen (p<0.05).

One hundred and thirty male and female broiler chicks from ages 21 to 35 days were evaluated. At the initial day of this experiment (d 21), 10 birds (as control group at initial phase) were slaughtered after blood collection, and 120 birds were divided as a completely randomized design, in 5 experimental groups, contains two normal chicken groups (include control and dill extract injected groups) and three hypercholesterolemic chick groups (include control, dill extract and lovastatin injected groups) with three replicates and 8 birds per replicate. Normal chicks were subcutaneously injected only by dill extract (25 mg/kg body weight/d) at days 21-28 and hypercholesterolemic chicks were injected by dill extract plus cholesterol (50 mg/kg body weight/d). Blood samples were collected at day 28 from half of the birds and at day 35 from the others and then they were slaughtered and tissues Sample were removed and maintained at -20°C until testing. The results showed that a seven-day period injection causes increased levels of blood TC, TG and LDL compared with the control group (P<0.05). In hypercholesterolemic chicks, levels of blood LDL and Breast muscle cholesterol at the end of a seven-day period (day 28) increased and level of blood HDL decreased by dill extract injection rather than control group (P<0.01). Lovastatin injection in hypercholesterolemic chicks Compared with dill extract had no difference in most investigated parameters. In general dill extract like lovastatin, had not lowering effects on blood and tissues cholesterol in normal and hypercholesterolemic chickens.

A number of experimental studies have reported that the absence of scales in some scaleless fish species causes toxins to absorb faster in the fish body including the skin, muscles and other organs, possibly leading to potential considerable impacts on the consumers. Although numerous researchers studied heavy metal pollution in aquatics, in vitro comparison of heavy metals uptake in the scaled fish, common carp, with the scaleless striped catfish, and also the role of scale coverage in heavy metals absorption are absent. First, lethal concentration (96 h LC50) was determined for each species. Then the fish were exposed to sub lethal concentrations (10% of LC50 values) of Pb at triplicate treatments for 15 days. The examined tissues from each species were sampled at day 15 of the experiment. Following chemical digestion, each tissue was analyzed by atomic absorption unit (Model Thermo) to measure heavy metal concentration. Final contents of Pb in the catfish's tissues were 1.63 times those in the carp’s (excluding the scales). The catfish's muscle amassed 14.6 times Pb than that of the carp. Lead residual in carp’s aquaria was much higher than that in the catfish’s signifying comparably lower metal absorption by carp’s tissues. The experimental results indicate much lesser lead accumulation in carp's muscle due to its scaly skin compared to scaleless skin of catfish. Hence, the scaled body provides an effective protective layer against environmental chemical contaminants, which can justify the consumption of scaly fishes with presumably rather safer muscle.

In the last few decades pollution of the aquatic ecosystems is a serious problem. Persian Gulf due to special condition of it is one of the ecosystems affected by contaminants. The present study aimed to investigate the effect of industrial and municipal wastewater in gill and of Liza klunzingeri. In order to do this study, 45 fish were collected from three sampling sites in Bandar Abbass: delta of Shure River (control), ship building and suru in Aban 1390. After anesthesia of fishes, specimens from of second arch in right gills were fixed in formalin 10%. Routine procedure histology methods were done and five micron thick sections were obtained and stained with hematoxilin-eosin then examined in light microscopy. Histopathological alterations were not seen in control gill. Histopathological alterations in gills of two polluted stations were including: epithelial lifting, oedematus space, hyperplasia of epithelial cells, lamellar fusion, clubbing, blood congestion and hyperplasia of chloride and mucous cells. Meanwhile parasite pollution was seen in some specimens of suru station also aneurism was seen in a few specimens of ship building station, too.
