Today, freshwater ecosystems polluted by heavy metals such as cadmium(cd2+) and lead(Pb2+) in Iran and other countries is an important environmental problem. Discharge of sewage and waste water into surface waters is one of the most important sources of heavy metals pollutions. Surface adsorption of heavy metals by polymer from waste water is one of the most recommended methods for water resource filtration. Poly (ethylene terephthalate) – Grafted – 2- Hydroxy Propyl Methacrylate was used as surface adsorbent in this study. The properties of produced adsorbent were studied. The results were showed that the contact between 1M NaOH and sorbent was not significant change in sorption properties. The adsorbent were used for filtration of Cd2+ and Pb2+ ions from pure laboratory solution and Isfahan steel factory wastewater. The results were showed that the maximum adsorption capacity for Cd2+ and Pb2+ were 23.44 and 20.9 mg/g respectively. The comparison of filtration Cd2+ and Pb2+ from pure laboratory solution and Isfahan steel factory wastewater were showed that the amount of Cd2+ filtration from both solutions were equal. The removal of Pb2+ from Isfahan steel factory wastewater was equal 54% of adsorption amounts from pure laboratory solution. The results proved that the produced adsorbent was useful for removal of cd2+ and Pb2+ from wastewater.

The Iranian cave barb (Iranocypris typhlops) is a species of ray-finned fish of the family Cyprinidae from a single locality in the Zagros Mountains, western Iran. Iranocypris thyphlops is currently recognized as a vulnerable species according to the IUCN Red Data Book. The species faces many natural and human threats in the native habitat. These threats can affect the fish survival and this can have important consequences regarding population extinction. So, in this study, SWOT analysis was performed using the analytical hierarchy process (AHP) for strategic management of the native habitat. Results showed the following ranking of each SWOT group priority: 1) Weaknesses, 2) Strengths, 3) Threats and 4) Opportunities that reflects the impact of weaknesses in the management of the ecosystem. According to the analysis, the most important factors in SWOT is “Unique habitat” from Strengths group, “rock falls” from Weaknesses group, “develop ecotourism” from Opportunities group and “happen fault” from Threats group. The results of this study can be a guide to the wildlife managers that based on the findings manage and conserve of this species.

To evaluate the effect of some managerial parameters on the performance 150 poultry laying flocks (room) from 15 commercial laying farms in Alborz and Tehran provinces of Iran were studied in this experiment. The educational information’s of the managers, geographic location and condition of flock health, nutrition and lighting program were collected thorough questionnaire distribution among the technical managers of commercial egg laying farms. Another required information such as light color, diet properties, feed intake, egg production were collected with direct observation and referring to the preexisting data which registered in the farms notebooks. For evaluation of egg quality, 10 eggs from each flock randomly selected and maintained under standard condition until laboratory assessments, then in the laboratory the egg quality parameters such as egg weight, egg edible percentage, egg yolk color, egg shell thickness, dry egg shell weight, yolk weight, and egg shape index were evaluated. Data from this study were analyzed using the GLM procedure of SPSS20 statistical software with t-student test (for 2 data groups) and F test (for more than two data groups).The results showed that the relevance of the managers profession with their education resulted to some decreases in yolk color, yolk weight and feed consumption and an increase in mortality (P <0.05). Farm manager training reduced yolk color, egg shell thickness, yolk weight, haugh unit, egg shape index, feed intake and mortality is increased (P <0.05). Percentage of yolk and feed to egg conversion were higher yolk color and egg production were lower in Varaminian flocks rather than Karaj flocks (P <0.05).Using of pelleted rather than mash feed resulted in some increases in yolk color, egg shell thickness, egg shape index, feed intake, feed to egg conversion and resulted in decrease of mortality (P <0.05). Haugh unit, feed intake, egg production and daily egg production per hen were reduced when ration prepared outside of farms rather than inside of them (P <0.05). Previous Conflict of flocks with disease rather than no previous conflicted flocks resulted in increase of egg shell thickness, egg shape index, and feed intake, feed to egg conversion, and decrease in egg weight, daily egg production and mortality. The use of CFLs compared to incandescent lamps increased egg weight, yolk color, egg contents weight, yolk weight, feed intake, and mortality but egg production and daily egg production per hen was decreased (P <0.05).The use of white light in the room decreased egg weight, content weight and daily egg production per hen rather than other colors but increased the yolk color. Use yellow light rather than other colors in the room, resulted to decrease of Haugh unit in the flocks. In total having previous disease background in the farms resulted to that farmer tended to be more sensitive and have more attention to their farms. More attention needed in educational and training programs for farmers to produce the high quality products rather than other aspects of production.

Due to study the food regime of Arius dussumieri, a total of 132 specimens were collected from the Oman Sea waters. The length – weight relationship was calculated as: W=aL2.91 in which it shows the isometric growth. The stomach content, were taken into consideration and it was found that the amount of full, semi-full and empty stomachs were 31, 33 and 36 %, respectively; of which the highest frequency was in winter (74%) and the lowest was in summer (24%). The GaSI shows better feeding condition of A.dussumieri in spring and summer but feeding frequency (mostly in males) were decreased in autumn and winter. The Food Preference (FP) Index was estimated as: fishes (39%), crustacean (40%) and molluscs (20%) namely all of them are considered as minor food in all four seasons. The most important food items were identified as 1) fishes consist of: Carangid, Engraulids and Leiognathids; 2) crustaceans as crabs: Portunidae and Porcellanidae families; shrimp: Alpheidae family; and 3) mollusks consist of cephalopods: Loliginidae and Opisthoteuthidae; gastropods: Muricidae and Naticidae.

This experiment was conducted to evaluate the effect of different feeding frequency of guppy (Poecillia reticulata) by pellet and live foods containing Artemia, Daphnia and Chironomid larvae on their reproductive and growth parameters. Fish were divided randomly into 10 group (1 -10) and Three replicate tanks were used for each group with a total of 10 fish stocked in each tank. After adaptation, fish fed by 10 diets (1-10). Results showed that the highest significant final weight, larvae survival (%), SGR, daily growth (%), body weight gain (%) and condition factor were observed in group 1 (one day feeding by pellet and one day feeding by Artemia) (P<0.05). The lowest final weight was recorded in group 5 (two days feeding by pellet and one day feeding by Daphnia). Moreover, the results of the final weight showed no significant difference among group 3 (three days feeding by pellet and one day feeding by Artemia), 5, 6 (three days feeding by pellet and one day feeding by Daphnia) and 7 (one day feeding by pellet and one day feeding by Chironomid larvae) (P>0.05). Survival rate of larvae was significantly (P<0.05) lower in group 8 (two days feeding by pellet and one day feeding by Chironomid larvae). Collectively, this study showed that reproductive and growth performance of Guppy can be improved by feeding live food, especially Artemia.

per
Today most destruction of environmental is the habitats. Hence, the need for methods that can help them to evaluate the habitat, and the over time obtained quality in this habitat. In this study was performed habitat evaluation of the Afghan Pika with Habitat Evaluation Procedure (HEP) and Binary logistic regression. Then, the results of these two methods were compared. Major factors as a variable habitat for species habitat evaluation were measured included: Average of the dominant slope, the aspect, altitude and land cover. Results of the two methods of modeling suggest that land-cover variable has an important role in the Pika habitat suitability which for this species is in rocky areas with cliffs and slopes over 30 degrees with small spaces between the rocks and also the geographical aspects which this species preferred are from north to south. Results showed that the height depending on other variables can be positive or negative, and usually in this region pikas live at altitudes between 2100 to 2300m. Finally, we obtained a model for Pika Habitat Suitability Index (HIS) and also models to predict the Pika presence.
