Khozestan province south western of Iran is a place with high distribution of Scorpions which are belonged to Buthidae, Scorpionidae and Hemscorpionidae families. The venoms from Buthidae scorpion specially have neurotoxins which specifically act on ionic channels in excitable cells of membrane. Apistobuthus sosane belong to buthidae family, which is yellow in color and its length is about 10 centimeter which is hunter from sandy places. its typical feature is that the second segment of tail is bigger than other segments. The target of this study was isolation and identification of toxic fraction venom of Apistobuthus sosane scorpion. In this study we used UV lamp for night collection of scorpions. Their venoms were extracted by electrical stimulation and were freeze-dried and mucoproteins of venom were separated, than the venom and fractions were injected to 18-20 gram albino mice for LD50 determination According to Sperman and Karber method. The venom was loded on a sephdex G50 column and fractions were collected according to UV absorption at 280 nm wave length. The toxic fraction Asf2, crude venom with the marker was electrophoresis. Molecular weights of toxic fraction 6 KD were collected.

This study was conducted in the winter of 2011 at Yard Pars Steel Ship near Bandar Abbas, Hormozgan province, to determine the amount of heavy metal (iron, copper, lead and nickel) contamination in the sediment of the area in order to investigate the impact of the ship recycling industry on the sediment. Has found. Based on the results, the maximum iron content in the sediment was measured at 2.2402 ppb at the ship's recycling station (station b). Similarly, the highest mean copper in sediment was estimated to be 34.37 ppb and 0.32 ppb in station b. Nickel content was 0.18 ppb (in station c 300 m from station b). All concentrations were below the epa standard. According to one-way ANOVA test, there was a significant difference (at 95% confidence level) between the concentrations of Fe, Cu and Pb in sediment of station b (main scrub site) with other stations. There was also a significant difference between the concentration of nickel in sediment of station c with stations a, b, d and e (p <5%) According to the results of the present study, heavy metals of iron, copper, lead and nickel They are released at the ship's recycling site. Although all concentrations are below the EPA standard, this study demonstrates the importance of the impact of such activities on the environment, possibly due to the limited activity of the ship's vessels in the area.

In this research 120 individuals of lizards belonging to 6 families (Lacertidae, Gekkonidae, Phyllodactylidae, Agamidae, Scincidae and Eublepharidae), 11 genera and 11 species were collected from Mehran region in Ilam Province and scrutinized for existence of ectoparasite. Our results demonstrated that among these, two families of Scincidae and Eublepharidae lack any parasite on their skin whereas the other four families possess mite pockets containing ectoparasite on different site of the body. The mite pockets occurred around eyes, inside ears, within scales and skin folds of the hosts. In general, ectoparasites were found in the members of 6 lizard species including Ophisops elegans (Lacertidae), Asaccus elisa (Phyllodactylidae), Laudakia nupta (Agamidae), Cyrtopodion scabrum and Carinatogecko heteropholis (Gekkonidae). The parasites were found on these lizards were belong to the genera Geckobia (Pterygosomatidae) and Trombicula (Trombiculidae) which occurred in high intensity in Ophisops elegans but with lower number on other species. Based on the results obtained from Asaccus elisa no gender difference is observed in terms of the number and intensity of infestation.

Polycyclic aromatic hydrocarbons (PAHs) have different physiological effects on aquatic organisms. Glutathione S-Transferase (GST) as a biomarker of PAHs in liver of mudskipper (Periophthalmus dussemerie) was analyzed. Polycyclic aromatic hydrocarbons (PAHs) were assessed in the sediments and liver of mudskipper along the coast of north western part of Persian Gulf (Khuzestan coast). PAHs and GST were measured by HPLC and spectrophotometry methods respectively. Total PAH concentrations in sediment and liver tissues ranged between 113.50-3384.34 ngg-1 dw, 3.99-46.64 ngg-1 dw. The highest PAHs concentration and enzymatic activity were identified at Jafari site while the lowest were at Bahrakan. Significant correlation was found between GST and PAHs.The results of this study confirmed the use of mudskipper (P. dussemerie) as a bioindicator of PAHs pollution in marine ecosystem. The results also indicate that GST in p. dussemerie could be extended as a biomarker of polycyclic aromatic hydrocarbons (PAHs).

Significant morphological and physiological changes occur in the early development of fishes. This study was conducted to investigate the embryonic and pre-larval development of fighting fish (Betta splendens) in different temperature (24, 27 and 30°C) from oocyte activation to time of free swimming. Spawning occurred in tanks at 28 °C. Fertilized eggs were removed rapidly from the breeding tanks and put in the rearing tanks with different temperature (24, 27 and 30 °C). Diameter of fertilized eggs was determined around 0.8 mm. They were white, typically when deposited, very large vitellogenin and small privitelin space. Eggs and larva in different development stages and temperatures were sampled and taken pictures. The minimum time for arrival to specific developmental stages including: first cleavage, 32 and 64 cells stage, mid blastula stage, 50% epiboly, tail bud formation, heartbeat begins, hatching, opening the mouth and finally free swimming) at 24, 27 and 30 °C was recorded. Higher hatching rate and larva faster growth occurred at 30°C show that this temperature is most suitable for egg incubation of Siamese fighting fish.

To determine the effects of garlic extract on egg yolk cholesterol, egg microbial load, and productivity of egg-laying chickens at different intervals, Spain made garlic extract, Garlic on brand was applied. As many as 392 egg-laying hens of Hi-line race and all 30 weeks old were randomly classified in separate but equal groups and for 6 weeks received seven types of drinking water mixed with different garlic extract concentrations and same nutrition ratio. The first treat was control treat so it only contained pure water. Second treat contained 0.01 % garlic extract and was supplied for two days. Other treats were respectively as follows; 0.02% for two days a week, 0.01% for four days a week, 0.02% for four days a week, 0.01 % for six days a week, and 0.02% for six days a week. Through out experiment, the flock was observed and quality of yolk cholesterol, blood serum, egg shell microbial load, egg contents, production percent, egg bulk, egg weight, FCR, and egg shell thickness were recorded. The information obtained during six weeks was statistically analyzed. At the end of third and seventh week and also one and two weeks following experiments, sampling was carried out. According to results, it was only at the end of sixth week that the mixture of garlic extract with drinking water significantly affected on cholesterol of control group and other garlic extract consumers (P<0.05). However, among other treats, significant difference was not observed. Regarding blood serum cholesterol, in spite of blood cholesterol reduction at the end of experiment, no significant difference was detected among treats (p< 0.05). Egg content and egg shell microbial load didnt show significant difference from control group (P> 0.05). At third week, egg shell thickness significantly reduced compared to control group in other treats (P<0.05). However, at the end of sixth week, no significant difference was noticed (p>0.05). Regarding egg bulk, production percent and FCR, there was no significant difference between treats (p >0.05). Finally, it can be concluded that garlic extract consumption could only increase yolk cholesterol up to 17% and didnt have any other impact on egg-laying hens. By the way, the most economic consumption of this extract is 0.01 % for two days.

Today, modeling risk prediction as an effective strategy to protect the interests of human and wildlife populations is considered. The application of output maps such models to determinant the distribution range of conflicts; cost estimates and success of control programs are very beneficial. In the present study, we present a risk map for gray wolf (Canis lupus) attacks on human in Hamedan province. Thus, evaluation the performance of maximum entropy (MAXENT) modeling method to two methods presence/absence of artificial neural networks (ANN) and Support Vector Machine model (SVM). Based on predictions obtained north and center of the province are facing with high occurrence of wolf attacks. The results showed the important effective factors in distribution of wolf attacks are land use, human density and distance from the road. Between these factors, the land use was identified as the most important parameter. In addition, according to the results, the maximum entropy method, amount allocated area under the curve was greater (AUC =0.88) that indicates the high efficiency of this method in prediction of high risk areas in Hamedan province.

The Agamid genus Trapelus is one of the least studied genus and distributed throughout the desert and semi-desert regions in north Africa, eastwards in to the Middle East and Central Asia, as far east as eastern Kazakhstan and western China. The Trapelus consists of 4 species in Iranian plateau: T. agilis, T. lessonae, T. ruderatus, and T. megalonyx. T. agilis complex is the most complicated and widespread species complex and consists of 3 subspecies in Iran: T. a. agilis, T. a. sanguinolentus, and T. a. khuzistanensis. We studied 81 specimens (35 juveniles, 46 adults) based on 3 morphometric and 12 meristic characters from Torbat-e-Heydariyeh (27 specimens) and Neyshabour (54 specimens) cities. Results revealed that mean of snout-vent length were 60. 40 in males and 63. 41 in females, mean tail length were 89. 24 and 90. 74 in males and females respectively. Numbers of scales around midbody in all specimens were 59-83 (mean 69. 32±0. 64) and numbers of internasals were 3-5 (mean 4. 01±0. 08) Mean number of preanal callos scales were 18. 92 and 7. 86 in males and females respectively. Tails of all juveniles (%100) were original and complete and only one adult specimen was tailless.

The research was accomplished in order to study of behavioral and histopathological effects of Copper to Rutilus rutilus caspicus. The studied was performed by Water Static Method during 96 hours. 15 fish with average weight 2±0.5 g were encountered with different concentrations (0,. 0.1, 0.2, 0.3, 0.4 mg/l) of Copper. A group of fish was considered as control. Under stable condition and aeration, the lethal concentrations were detected 0.4 mg/l. Results indicate, there was significant differences between lethal rate with each other when copper concentration was increased (p<0.05). The experiments revealed, in the high concentration of Copper nominal signs of toxicity as convulsion, air gulping and opened operculum were happened. Histopathological findings were showed that, major lesions in tissues were hemorrhage, hyperemia, hyperplasia and edema and cells necrosis.

Success in aquaculture is based on various criteria, and the selection of a suitable feed and its potential use is important. The possibility of using fairy shrimps as diet in aquaculture has not been explored widely. Among the live diets used in the aquaculture, fairy shrimps have the potential to be used as a feed item for fishes such as ornamental fishes that benefit from live food. Also, their cysts and nauplii are useful in larval culture, mainly due to their convenience and availability. Branchinecta orientalis belong to the Anostracans, is a common inhabitant in seasonal water catchments in Northwest of Iran. In this study, growth rate and survival of this species was studied for 15 days using two different unicellular algae, that were combined with given amount enriched yeast. Newly hatched nauplii were grown until sexual differentiation under laboratory conditions (21 ±1°C temperature; 12L/12D photoperiod; 1600 Lm/m2 intensity; 200 nauplius L_1 density) feeding on two specie of unicellular algae Haematococus sp. and Scenedesmus sp. Results were analyzed using One-way ANOVA was used to test mean of different variables. No significant difference was observed on the growth rate and survival between the two treatment groups (p > 0.05). Also our findings provide valuable information on B. orientalis high nutrition value and its capability to use in aquaculture.

PAHs are important environmental pollutants because of their ubiquitous presence and carcinogenicity. The present study investigated effects of naphthalene (NAP) as one of the most important hydrocarbons on gill structure and plasma cortisol and T3 levels in klunzingeri mullet (Liza klunzingeri). Fish were divided to control and treatment groups. Treatment fishes received 50mg Bap dissolved in10µl coconut oil per (body weight) that were implanted peritoneal. Control group were implanted with coconut oil (10µl/g body weight) without BaP. Sampling was carried out 72 hours after implanting. During sampling time (While Sampling) fish were anesthetized then blood and gill arch were sampled. According to the results plasma levels of cortisol and T3 significantly increased and decreased respect. Respectively in both control and treatment groups NaP exposure stress caused increasing gill histopathological lesions such as epithelial hyperplasia, epithelial lifting, vascular congestion and mucus hyper secretion was evident. NAP exposure stress caused some alteration in plasma cortisol and T3 levels and increasing gill histopathological lesions. So according to disorders in hydromineral balance and survival are expected. According to the results plasma levels of cortisol and T3 significantly increased and decreased respectively in both control and treatment groups NaP exposure stress caused increasing gill histopathological lesions such as epithelial hyperplasia, epithelial lifting, vascular congestion and mucus hyper secretion was evident.

A study to determine the effect of varying dietary prebiotic Immunogen levels on the growth performance, hematological parameters and intestinal microbial balance of (Acipenser persicus), was carried out. The commercial prebiotic, Immunogen, were mixed thoroughly with the artificial feeds at concentration of 0.0 (control), 0.5, 1 and 2 g kg-1 dry diet and fed to healthy fish (27±0.45 g) at 2 - 3.5 % of their body weight daily in two split doses for 8 weeks. The trail was carried out in 12PVC tanks 500 liter which was filled with about 200 liter of water. That all tanks 12 juvenile Persian sturgeon were stocked. During the experimental period, weight and length of fish were recorded at an interval of 14 days. We studied also hematological parameters and intestinal microbial balance of fish at the end of the experiment. Results showed that specific growth rate (SGR), food conversion ratio (FCR), feed efficiency (FE), body weight gain (BW %) and net production (NP) were significantly (P<0.05) different among the experimental groups. no significant difference were observed in body composition (P>0.05). There were no significant differences (P>0.05) in the haematocrite, hemoglobin, total protein, glucose, albumin and globulin among the treatments. Results also showed that white blood cell (WBC), cholesterol and cortisol levels were significantly (P<0.05) different among the experimental groups. In addition, microbial analysis showed that colony forming units (CFU) and intestine Lactobasilus were significantly (P<0.05) different between control and other experimental groups.
